Lac is a national large public chain entity mining company
The formula of long-term marginal cost is expressed as:
LMC = △ LTC / △ Q
or: LMC = DLTC / DQ
Mr = AP = P, which is the characteristic of perfect competition market, that is, the demand curve P (q) of perfect competition market coincides with marginal cost curve MR and average cost curve AP. Mr = LMC = SMC = lac = sac, which is the condition of perfect competitive market equilibrium
LMC, SMC, lac and sac were long-term marginal cost, short-term marginal cost, long-term average cost and short-term average cost respectively
Because lac is the envelope of sac, return to scale changes and remains unchanged in the long run. If the return to scale remains unchanged, lac = LMC, which is the lac straight line and the lowest point of sac Increasing or decreasing returns to scale: the lowest point of the intersection of LMC and lac with lac, which is the lowest point of SA corresponding to proction 
extended data:
(1) each STC and LTC has only one common point. This is because for each STC, there is only one point tangent to the line from the origin. Or, it can be said that for each sac, there is only one point intersecting with SMC, and at this point sac drops to the lowest point
(2) STC can only be located above LTC, that is, except for common point, all other points on each STC are larger than LTC under the same proction state. Otherwise, if the STC falls below the LTC, it means that the short-term average cost sac is less than the long-term average cost lac, which is contradictory to the fact that lac is the lowest point of sac
(3) STC is tangent to LTC only when lac reaches the lowest point. This is because at every point on the LTC, it is the common point with an STC. At these common points, the corresponding STC is tangent to a straight line from the origin respectively,
however, for LTC, it is tangent to a straight line from the origin only when the lac drops to the lowest point. Therefore, except for the point on the LTC corresponding to the lowest lac, LTC and STC all intersect, and there is only one intersection
to put it simply: a dealer opens a market, and then draws people in to invest. Of course, the return is also great. For example, if you invest 1000 yuan, you will get 100-200 yuan in a week. What a banker with such a high profit can do to give you such a high profit is that he supports your profit with other people's investment, and goes on like this all the time, and pays the early entrants with the later entrants. The consequence of such a cycle is that bubbles are bigger and bigger. When no new people come in, the dealer will crash and run away. This is the reason why people who enter the site in the early stage can make compensation, while those who enter the site in the later stage will make compensation
in addition to making cash early, it also depends on luck. The sooner you find out to play, the better to buy a car in half a year, the better to buy a house and a car in one year, and the better to buy a house and a car in two years
however, it's not good luck. When no one joins in to fill the hole in front of us, if we don't quit, we should go to jump off the building and cut the chicken instead
there are risks in any investment. If you dare to do it, you may get rich overnight or lose money overnight.
Lac is called L2TP access concentrator
The lac is located between the remote dialing user and the LNs device and is responsible for the data forwarding between the remote dialing user and the LNs deviceto forward data from lac to LNs, it is necessary to use L2TP protocol to establish a tunnel between the two devices, and PPP link is still used between lac and remote dial-up users

extended data
the coding method of Lac has corresponding regulations in every country, and China Telecom has clear regulations on the coding method of Lac on GSM network (see the system specification of GSM of the Ministry of Posts and Telecommunications)
generally, the allocation and coding of Lac have been determined in the initial stage of network construction, and there are few changes in the operation process. The size of location area code (LAC) is a key factor in the system
if the lac coverage is too small, the location update process of the mobile station will increase, thus increasing the signaling traffic in the system
On the contrary, if the location area coverage is too large, the same paging message will be sent in many cells when the network paging mobile station, which will lead to the overload of PCH channel and increase the signaling traffic on Abis interfacee to the strong mobility and burst in mobile communication, there is no unified standard to adjust the size of location area. The operation Department can make long-term statistics on the PCH load and signaling link load of each region according to the current network to determine whether to adjust the size of the location area
if the former phenomenon is serious, the location area can be appropriately reced, otherwise, the location area can be appropriately increased. In general, it is suggested that the location area should be as large as possible
the long-term average cost is the total cost of a manufacturer per unit of proction in the long run. The formula is lac = LTC / Q< br /> The U-shaped long-term average cost is e to economies of scale and diseconomies of scale. Economies of scale: the economic benefits of manufacturers are improved by expanding proction scale, that is, the multiple of output increase is greater than that of cost increase. Diseconomy of scale: e to the large scale of manufacturers, the economic benefits decrease, that is, the increase multiple of output is less than the increase multiple of cost
external economy and external diseconomy lead to the upward or downward shift of long-term average cost. External economy: factors outside the enterprise make the enterprise cost decrease. External diseconomy: factors outside the enterprise make the enterprise cost rise.
Part 1: Problems and improvement measures of property management involved in the case. This paper systematically analyzes the problems of property management in law enforcement and case handling of public security frontier forces, and the causes; Establish rules and regulations to standardize the property management system involved in the case; We should further strengthen the socialist concept of rule of law of officers and soldiers in ruling the country according to law, law enforcement for the people, fairness and justice, serving the overall situation and the leadership of the party, so that officers and soldiers can abide by the law enforcement proceres, pay attention to law enforcement methods, change law enforcement attitude and pay attention to law enforcement art, So that all kinds of law enforcement activities can be fully understood and accepted by the people. Key words: property involved in the case, concept of rule of law, daily supervision Author: Li Wei, teaching and research section of border defense business of Guangzhou border Command School, assistant lecturer. Chinese Library Classification Number: d920.4 document identification code: a article number: 1009-0592 (20XX) 12-208-02 "in all state powers, administrative power is the most rebellious, it is the only power that can be exercised without the help of proceres, and has great arbitrariness and broad space." As one of the contents of the exercise of administrative power, the management of property involved in the daily handling of cases by the public security frontier forces is related to the quality of case handling and the vital interests of the relative person. The management of the property involved in the case is an important link in the whole process of the case, so it is easy to be ignored. However, whether the work is in place and can be carried out according to law not only restricts the overall quality of the investigators
According to the previous answers on the Internet, I walked this road a few days ago. Now I'd like to make a detailed supplement:
1. Xitang bus station Taozhuang bus station: take k216 at gate 2 of Xitang bus station to Taozhuang (remember not to take the bus backwards, but wait in the station), and the ticket price is 2 yuan. Get off at Taozhuang bus station (be sure to get off at this stop, because the starting point of the next stop is here), about 20 minutes' drive
2. Taozhuang Luxu: after getting off at Taozhuang bus station, you will find a crossroad. Take K310 and follow Taolu highway to shuizhaqiao, the terminal station, about 20 minutes. The ticket price is 2 yuan. I also asked a few people to make it clear. It happened that K310 was stopped at the intersection and met two warm-hearted aunts and sisters, who were from luxui. They said that there was no bus after 4 p.m. We took a 3:00 bus. It seemed that there were only three buses in the afternoon. The bus waited at the intersection ahead of time and started at the arrival point. This is a picture of the car
you can find out the route on the network map. It takes more than two hours and costs a total of 5 yuan, which saves time and money compared with going to Suzhou first and then to Zhouzhuang. You can also see the human style on both sides of the road. We can see a lot of rape flowers on both sides of the road. I'd like to thank you for meeting those two aunts. They happened to lead us all the way to the 302 bus
I hope I can help you
