1. The Internet of vehicles is to collect and share automobile information through 3G mobile Internet. Through information processing, the communication between vehicle and road, vehicle and owner, vehicle owner and owner, vehicle owner and third-party service provider can be realized
the role of the Internet of vehicles is: it can realize information sharing through the interconnection of vehicles, vehicles and people, vehicles and roads, collect the information of vehicles, roads and environment, process, calculate, share and safely release the information collected from multiple sources on the information network platform, and effectively guide and supervise vehicles according to different functional requirements, And provide professional multimedia and mobile Internet application services<

from the perspective of network, IOV system is a three-tier system of "end management cloud"
the first layer (end system): the end system is the intelligent sensor of the vehicle, which is responsible for collecting and acquiring the intelligent information of the vehicle, and sensing the driving state and environment; It is a ubiquitous communication terminal with in vehicle communication, workshop communication and vehicle network communication; At the same time, it is also a device that enables cars to have the ability of IOV addressing and network trusted identification
the second layer (management system): it solves the interconnection of vehicle to vehicle (V2V), vehicle to road (V2R), vehicle to network (V2I), vehicle to person (v2h), etc., realizes the communication and roaming between vehicle ad hoc network and a variety of heterogeneous networks, guarantees real-time, servability and network ubiquity in function and performance, and is the unity of public network and private network

the third layer (cloud system): the Internet of vehicles is a vehicle operation information platform based on Cloud Architecture. Its ecological chain includes its, logistics, passenger and freight transportation, dangerous special vehicles, auto repair and auto parts, car rental, emergency rescue, mobile Internet, etc. It is a collection of multi-source massive information, so it needs cloud computing functions such as virtualization, security authentication, real-time interaction, massive storage, etc, Its application system is also a composite system of vehicle data aggregation, calculation, scheling, monitoring, management and application
it is worth noting that as of 2013, GPS + GPRS is not really the Internet of vehicles or the Internet of things, but a combination of technologies. At present, most of its experiments and IOV concepts in China are based on this technology.

2. There are essential differences between foreign exchange speculation and stock speculation:
1. Stock speculation is a daily turnover of 400 billion RMB in China, and foreign exchange is a global daily turnover of trillion US dollars
2, stock is t + 1, foreign exchange is t + 0. Buy and sell at any time. Buy and sell
3, 2 can do, I'm afraid not, you have to be careful.

The calculation formula of electric field force

(1) the general formula F = QE

(2) f = kq1q2 / R ^ 2

(3) uniform electric field F = Qu / d

(1) the definition formula UAB = WAB / Q

(2) uniform electric field u = ed

The interaction between

charges occurs through the electric field. As long as there is a charge, there is an electric field around the charge. The basic property of the electric field is its powerful effect on the charge placed in it. This force is called electric field force

voltage, also known as potential difference or potential difference, is a physical quantity to measure the energy difference of unit charge in the electrostatic field e to different potentials. Its magnitude is equal to the work done by the unit positive charge moving from point a to point B e to the electric field force, and the direction of voltage is defined as the direction from high potential to low potential

extended data:

the main unit of voltage in the international system of units is volt (V), abbreviated as volt, which is represented by the symbol v. One volt is equal to one joule of work per Coulomb of charge, i.e. 1 v = 1 J / C. The unit of strong voltage is kilovolt (kV), and the unit of weak voltage is millivolt (MV) microvolt μ v)

The conversion relationship between them is: 1kV = 1000V, 1V = 1000mV, 1mV = 1000V μ v

4. Electric field is a kind of special substance, which is an objective existence that is not felt by human senses. Electric field has the general generality of substance, that is, electric field has energy and momentum just like general substance. The energy of electric field is called electric field energy, which is different from electric potential energy. Electric potential energy is the energy of electric charge in electric field, Electric potential energy is similar to gravitational potential energy, which is a kind of system energy shared by electric charge and electric field. Electric potential energy is determined by the nature of electric field where electric charge is located and the quantity of electric charge ε＝ The potential of a certain point in the electric field is determined by the electric field itself, and is determined by the selection of the "field source charge", the space position and the zero potential point (the potential is a relative quantity). The potential of a certain point in the electric field is numerically equal to the ratio of the potential energy of the test charge at that point to the quantity of the test charge, That is u = ε／ The electrostatic force is similar to gravity and is a conservative force. The work done by the electrostatic force is independent of the motion path of the charge, and is determined by the difference between the initial and final positions of the charge in the electric field and the electric quantity of the charge, that is, WAB = q (UA UB) = quab, Potential difference (voltage) is a physical quantity reflecting the power of electric field force. The relationship between the work of electrostatic field force and electric potential energy is similar to the relationship between the work of gravity and gravitational potential energy, that is, the work of electrostatic field force is equal to the rection of electric potential energy (WAB =) ε a＋ ε b＝－ Δε．

note: (1) when two identical charged metal spheres are in contact, the distribution of electric quantity is as follows: those with different charges are neutralized first and then equally divided, and those with the same charges are equally divided
(2) the electric field line starts from the positive charge and ends at the negative charge. The electric field line does not intersect, and the tangent direction is the direction of field strength. The electric field is strong in the dense part of the electric field line, and the electric potential is lower and lower along the electric field line, and the electric field line is perpendicular to the equipotential line

The electric field line near the outer surface of the conctor is perpendicular to the surface of the conctor, and the combined electric field strength inside the conctor is zero. There is no net charge inside the conctor, and the net charge is only distributed on the outer surface of the conctor

7. The following three methods are commonly used to calculate the work done by the electrostatic force: w = FL (F is the electrostatic force, l is the displacement in the direction of the electrostatic force); W = E1-E2 (E1 and E2 are the potential energy at the beginning and end position respectively); W = Qu (q is the amount of charge, u is the potential difference between the beginning and the end)
the latter two formulas are commonly used in non transport electric field, and the first one needs integral method

Feeding method: the alpaca needs to be saddled with carpet before feeding

analysis of breeding methods: in PC version, alpacas can only be fed after they are tamed by riding on them. Alpacas like food is wheat, take out wheat long press two alpacas can be fed. In PC, alpacas don't eat wheat, but eat hay. Take out hay and right-click alpacas to feed. After feeding two alpacas, they will come out with red hearts, then they will squeeze together and give birth to a baby alpaca

9. This friend, the answer you adopted is wrong. He doesn't know anything at all. Different pets consume different things. Alpacas are lucky enough to add 6 better pets. For example, Pegasus, fire dragon and Christmas elk, the maximum amount of 50 cards is 3. Several of my friends only spend less than 200 cards to add 10, I can only add 4 to 200 cards of the enhanced feihuolong, and the consumption of coupons is also different. Feihuolong needs several times more than the enhanced alpaca. Even if the hand is disabled, it only needs more than 300, and the coupons are within 5W!
