1. MT is the abbreviation of maintank, which is the main anti boss role. MT is to use its skills to attract boss's hatred and become the main target of boss's attack. The main purpose of treatment is to increase MT's blood, and other classes output damage to kill boss and obtain equipment. The characteristic is that the equipment and talent are defensive or suitable for anti monster. Traditionally, MT is a warrior. Now there are a large number of knights and druids to do tank anti boss. In the case of more than five people, there is usually more than one tank. The number and occupation of tanks are selected according to the skills of combat and boss.

MT represents total moisture, mad represents air dry basis moisture, aad represents ash and VaD represents volatile
the water in coal is divided into internal water, external water, crystallization water and decomposition water
too much moisture in coal is not concive to processing, transportation, etc., combustion will affect thermal stability and heat conction, coking will rece coke yield and prolong coking cycle
ash refers to the resie of coal after combustion. It is not the sum of minerals in coal, but the resies of these minerals after chemical and decomposition. The high ash content indicates that the combustible content of coal is low. The calorific value is low
extended data :
the frequently reported moisture indexes are:
1, total moisture (MT), which is the sum of all internal and external moisture in coal, and is also commonly expressed by Mar. It is usually set below 8%
2. Air drying basis moisture (MAD) refers to the moisture content of coal in air drying state
can also be considered as internal moisture, which is called "analytical basis moisture" in the old national standard
fixed carbon content refers to the resies that remove moisture, ash and volatile, which is an important indicator to determine the use of coal. The difference of water content, ash content and volatile content of coal subtracted from 100 is the fixed carbon content of coal. According to the standard used to calculate volatile matter, the fixed carbon content of dry basis, dry ashless basis and other different standards can be calculated
3. 1. Definition: main tank or monster tank is a kind of character in MMORPG (massively multiplayer online role-playing game) who bears attacks. It is the abbreviation of main tank. Take the online game "world of Warcraft" as an example, MT is the abbreviation of "main tank", and is the only player with a special identity in the team<

main tank [or monster tank], a character who bears attacks in MMORPG, is the abbreviation of main tank. Take the online game "world of Warcraft" as an example, MT is the abbreviation of "main tank", and is the only player with a special identity in the team“ "Tank" is the main bearer of monster's hatred in team replica combat, that is, the target of monster's attack. Because of their existence, other players can output damage safely. It's called "tank" and it's vivid. Because as a "tank" role in general, they have to have high armor, defense skills, resistance, and HP. In a word, he has a strong anti Strike ability. He is also the main treatment undertaker in the team. There will be several tanks in a team activity, but MT only refers to one of them, who is responsible for tank work when fighting with boss. Therefore, MT is the backbone of a team. His operation level, consciousness, equipment, resistance equipment and even network speed have a great impact on the team's progress. So MT will have a special position in the mind of world of Warcraft players
difference
MT is not equal to tank, it is the core of a team, the core of the whole team and even the guild, and it is also a very special existence in the guild or a team. It's not only boss, sometimes a lot of small monsters, a lot of important strongholds, and the team commander may be Mt. MT not only needs all the above factors, but also needs the judgment and control ability of the whole scene. In a team battle, MT is often the first to start the monsters. For the scene and team configuration, it needs more strict requirements. In a team, there can be many tanks, but MT (main tank) has only one. In the wow team, the ones who can take the responsibility of MT are: Druids, the wild protection talent (bear talent); Paladin of protection talent; Defense warrior, DK (Death Knight) of blood talent of new class in wrath of Lich King, and martial monk of wine talent of new class in riddle of pandaria<
2 main tank meaning editor
the reason why you need a main tank is that when you fight with powerful monsters, it is often the healing class and the damage exporter will be attacked by a few monsters and die. Even if they can find a way to live on their own, or recover from the therapy profession, their main responsibilities and work will be disrupted. Therefore, the most effective way is to have a main tank with high armor and high enrance when fighting with these monsters, maintain hatred against monsters, and enable healing classes and damage exporters to focus on their own work
in the recent expansion, "fission of the earth" has four classes that can be used as main tanks: Defense warrior, guardian Druid, protection Paladin and blood death knight, and "mystery of Panda Man" has added the martial monk class, and Jiuxian is an optional tank talent. Although other classes can sometimes be used as tanks, they will not be called "main tanks"
before the release of the "burning expedition" expansion, only soldiers could act as the main tank, so it was long (and now is) difficult to train a soldier to become a tank. At the end of the day, only a small number of players are able to be the main tank. Because the position of the tank is extremely important, the soldiers with excellent operation and equipment are highly valued. The importance of the main tank lies in this, so some trade unions disbanded because their main tank withdrew
with the revision of later versions, other classes can also become tanks. Therefore, the main tank may not be a soldier, but the main tank is still a very important member of any trade union or team.

4. Oh, don't make a mistake.
MT = metric ton & quot; Metric tons & quot; 1000 kilos is a metric ton<
so the above meaning is:
shipment (loading): 25000 metric tons per month.
others such as:
demand amount of minimum 50 MT per month
MT = metric ton & quot; Metric tons & quot; 1000 kilos is a metric ton<
so the above meaning is:

5. Main tank, a character in MMORPG, is the abbreviation of main tank. Taking "world of Warcraft" as an example, the classes that can act as MT include Warrior (Defense), Paladin (protection), Druid (wild bear) and death knight (Frost). In fact, some specific boss also need mages and warlocks to act as Mt, And these bosses are generally magic department. MT is the only player with a special identity in the team“ "Tank" is the primary maker of monster hatred in team replica combat, that is, the first target of monster attack. Because of their existence, other players can output damage safely. As a "tank" character, you usually have high armor, defense skills, resistance, and HP, or specific skills, such as mage's spell stealing. In a word, he has a strong anti Strike ability. He is also the main treatment undertaker in the team. There will be several tanks in a team activity, but MT only refers to one of them, who is responsible for tank work when fighting with boss. Therefore, MT is the backbone of a team. His operation level, consciousness, equipment, resistance equipment and even network speed have a great impact on the team's progress

6. Manual transmission (MT) is the most original transmission. It adopts dry friction clutch and gear set. Since the number of teeth in each gear set is fixed, the gear ratio of each gear is a fixed value (that is, the so-called "stage"). For example, the first gear ratio is 3.455, the second gear ratio is 2.056, and then the fifth gear ratio is 0.85. These numbers are multiplied by the final drive ratio to get the total transmission ratio. There are only five values in total (5-gear manual), so it is a staged transmission.
7. MT: management training
what is Mt? How can a MT be achieved?
first of all, as a MT, you have to be responsible to 40 people, even to the guild. You have to have a strong sense of responsibility. What you have to do is not to hold the hatred. For example, if you are a flower gatherer, go to Dongquan to collect more ice caps when you have nothing to do. Withered leaf grass, graveyard moss, mountain rat grass, golden ginseng and so on are also needed. Not a flower picker? Go to the farm element flame. Are you a armor blacksmith? Let's do all the prestige tasks of the seyin brotherhood earlier, so as not to waste time in the future. More for raid, more for the guild to do something, so as to convince the public
personality is also a very important point. It is not recommended for people who have no opinions or weak personality to be Mt. Because MT & quot; Must & quot; In 40 people to have absolute high prestige, and to have enough judgment to quickly form their own opinions. For example, an unexpected defeat of the regiment, or a boss can't get through,
What's the reason? 40 people may have a lot to say. At this time, you need to say the reason you think, point out the way to overcome, and convince everyone. This is not what the raid leader should do, this is what you should do
in addition, how to coordinate the relationship between yourself and the raid leader is also very important. I don't think MT is suitable for doing what raid leader does
because MT is basically busy in the whole process, there is not much time for you to type or even press macro. What's more, many things that raid leader does are also very troublesome, such as making DKP, distributing goods, directing, and so on. Since it's hard to be a good raid leader, it's very important to try to make the raid leader and yourself like a person. You and he need to adapt to each other
technical problems. The most important thing is what you should pay attention to when playing boss according to the characteristics of your team. As a MT, you must be clear about these problems. The technology here is not only your own. You should know every detail, what should be paid attention to by mage and what should be paid attention to by PREEST. In this way, you can point out that someone is wrong, and don't expect others to be able to learn from themselves without any teachers. Moreover, as a whole, no one can see it more clearly than Mt. At the same time, it's needless to say that your own tank technology is very important, but it's often ignored. Walk with great accuracy. Don't go beyond the priest's ability to move. Keep a clear mind and sense of orientation, and don't be afraid of the size of the boss, which is particularly important in the face of black dragon, Shazzrah, blue dragon and other boss
finally, communicate with your offtank. Well, no one will willingly give you purple equipment unless they believe you. You also have to believe in their ability, because you can only stand boss, not stand by. Sometimes you can't trust your pastor when you face the boss of Qing hate. But you also have to be able to point out their shortcomings. Many priests like to be close to tanks, which is a big mistake. You should criticize the treatment teams that don't keep three hot in the big skill big blood drop and don't shield in the boss war
well, if you can do what I said above, your MT road will only be short of some equipment. Below I list the equipment that I think is qualified for MT when I first entered MC. I try to list the equipment that is easy to get and works well. At the same time, MC needs at least three sets of equipment, fire resistance, dark resistance and physics. But as long as you have a set of physics, it's OK to play 1-9, just die a few more times. For physical equipment, you should have no buff more than 5000 blood, 410 defense skills or more, dodge + Parry & gt; 30%，7000AC In this premise to meet, try to improve their defense skills, Dodge, parry, grid and HP
the most important thing is to improve defense skills to 420 +, followed by HP, dodge and parry, then grid, grid value and AC< Head:
you should choose the stone skull helmet of BRD 98. He's a little better than alertness, because using alertness and then using dodge boots doesn't have enough defense skills. Mercer helmets are better, of course, but it doesn't matter if they don't
Necklace:
it is absolutely the best Medal of Marshal Mo XX. The world falls, please stay ah<
shoulder:
since there is prison shoulder armor, and since it is often sold in ah, you should buy it, and you don't need to replace it with anything else
clothes:
the clothes dropped by the commander of DM north are the easiest to get. The next easy thing is the last step of the love and family task to get the armor clothes. More difficult is to rely on character in the channeling play six small boss out of the blue board clothes. Colorful dragon breastplate? It's not for tank physics boss
the advantages and disadvantages of the above three are just opposite to the difficulty<
wrist:
believe me, you just need to buy a first-class sergeant's plate armor wrist. Of course, you can spend a lot of time with the Warlock to kill the thousand g horse task boss and expect him to lose a wrist with + 5 defense skills. Channeling also lost a 7agi17sta wrist, which I'm using<
weapons:
the most easily available and practical weapons are the trimmer dropped by the DM North guard and the hammer dropped by the prince of the West
shield:
please brush out the Dragon man shield and then become MT, thank you<
bow / gun:
take the blood wood of the mission, it's good. Although I think guns are more handsome
hand:
the most suitable hand is the world's falling stone holding hand guard. Buy it<
belt:
the most suitable belt is a green one, which is a reward for a task of BRD. It will accompany you a long way
legs:
the most suitable leg is the 2-flash 15sta drop of UBRS red. Use it. Believe me, this is the best one<
shoes:
this is the least suspense. Please believe that my dodge boots are better than the middle ones. This is a bug
ring:
if you don't have a good dragon ring (Dodge, enrance, monkey) in temple, then use the poet's magic King Ring + flesh and blood ring
or if you don't feel uncomfortable with green, the world drops a green ring 8str8sta5 defense skill, buy it. Sal's determination to sell<
Earrings:
the dog of DM West can take two earrings if it loses a 2% flash. Thrall will reward the black dragon for killing red in the middle of the mission. 1% grid 180 to prevent 10 Aokang. Soldiers Blue Book task reward please sell shop. There is also a 1% grid + AP is not good, do not wear him

Cape I forgot to say. The best cloak is DM north, the barrier cloak out of the box. Stone elephant ghost cape is not recommended, because it is estimated that the defense skills will not be enough
in addition, one of the earrings dropped by King BRD is good. It's a pity I didn't get it.

MT, manual transmission, also known as manual gear, that is to say, the gear meshing position and transmission ratio can be changed by manually moving the transmission lever, so as to achieve the purpose of speed change
most of the manual transmissions in cars are four or five speed gear transmission, and usually with synchronizer, which is convenient for shifting and low noise. When manual transmission is operated, the clutch must be pressed to move the transmission lever. Manual transmission is relative to automatic transmission. In fact, before the appearance of automatic transmission, all cars used manual transmission
extended data:
features of manual transmission. The most common manual transmission is 6-gear (5 forward gears, 1 reverse gear), and some cars use 7-gear (6 forward gears, 1 reverse gear) transmission
generally speaking, the transmission efficiency of manual transmission is higher than that of automatic transmission, so the driver's technology is good. The vehicle with manual transmission is faster than that of automatic transmission in acceleration and overtaking, and it also saves fuel
9. The first index: moisture
water in coal can be divided into internal water, external water, crystallization water and decomposition water
too much moisture in coal is not concive to processing and transportation, which will affect thermal stability and heat conction ring combustion, rece coke yield and prolong coking cycle ring coking
at present, we often report the water index as follows:
1. Total water (MT), which is the sum of all internal and external water in coal, is also commonly expressed by Mar. It is usually set below 8%
2. Air drying basis moisture (MAD) refers to the moisture content of coal in air drying state. It can also be regarded as internal moisture, which is called "analytical basis moisture" in the old national standard
the second index: ash
refers to the resie left after coal combustion
it is not the sum of minerals in coal, but the resies of these minerals after chemical and decomposition
the high ash content indicates that the combustible content of coal is low. The calorific value is low
at the same time, the ash content of coke is determined by the ash content
the common ash indexes are air drying based ash (AAD), drying based ash (AD), etc. It is also useful to use the (AAR) of as received ash
the third index: volatile matter (all called volatile matter yield) V
refers to the procts of heating decomposition of organic matter and some minerals in coal, not all of which are intrinsic components in coal, but also some of which are pyrolysis procts, so it is called volatile matter yield
the size of volatile matter is related to the degree of coal metamorphism. The higher the degree of coal metamorphism, the lower the yield of volatile matter
in combustion, it is used to determine the type of boiler; In coking, it is used to determine the proportion of coal blending; At the same time, it is an important index of vaporization and liquefaction
the commonly used volatiles are VAD, VD, Vdaf and var
Vdaf is one of the important indexes of coal classification
the fourth index: fixed carbon
different from the carbon of element analysis, it is calculated according to moisture, ash and volatile
FC + A + V + M = 100
the relevant formula is as follows: FCAD = 100 mad VAD
FCD = 100 ad VD
fcdaf = 100 Vdaf
the fifth index: total sulfur st
is a harmful element in coal, including organic sulfur and inorganic sulfur. Less than 1% can be used as fuel. In some areas, it is required to be below 0.6 and 0.8. Now the commonly used environmental coal and green energy refer to the coal with low sulfur content
common indicators are: Total Sulfur on air drying basis (st, AD), total sulfur on drying basis (St.d) and total sulfur on as received basis (st, AR)
there are also some other indicators, which mainly depend on what you need coal for, and then test what indicators!
water in coal can be divided into internal water, external water, crystallization water and decomposition water

different from the carbon of element analysis, it is calculated according to moisture, ash and volatile
FC + A + V + M = 100
the relevant formula is as follows: FCAD = 100 mad VAD
FCD = 100 ad VD
fcdaf = 100 Vdaf
the fifth index: total sulfur st
is a harmful element in coal, including organic sulfur and inorganic sulfur. Less than 1% can be used as fuel. In some areas, it is required to be below 0.6 and 0.8. Now the commonly used environmental coal and green energy refer to the coal with low sulfur content
common indicators are: Total Sulfur on air drying basis (st, AD), total sulfur on drying basis (St.d) and total sulfur on as received basis (st, AR)
there are also some other indicators, which mainly depend on what you need coal for, and then test what indicators!
10. At: refers to the hydraulic automatic transmission, that is, the ordinary sense of automatic transmission, 10 two automatic stop car, there must be 9 with at, technology is very mature
MT: it's a manual transmission. There are 1, 2, 3, 4, 5, R numbers and letters on the transmission lever. There are five forward gears and R is reverse gear. AMT: an automatic control mechanism is added on the basis of the manual transmission. Generally, it has hydraulic control and motor control, which is equivalent to a robot to help you shift automatically. Its basic structure is the same as MT (manual transmission).
