Due diligence, also known as prudential investigation, refers to a series of activities that investors conduct on-the-spot investigation and data analysis on all matters related to this investment of the target enterprise after reaching a preliminary cooperation intention with the target enterprise through consultation. Including financial due diligence and legal due diligence. The survey contents generally include: industry research, enterprise owners, historical evolution, human resources, market and sales, research and development, production and service, procurement, law and supervision, finance and accounting, taxation, management information system, etc.
Question 2: What do you mean by rootless and traffic-free intranet? Hello, I'm glad to answer your questions.
In order to provide convenience for customers, operators have provided some preferential policies, such as receiving multimedia messages, landing in the lobby and other services free of traffic charges.
In order to distinguish whether users are using traffic-free services or surfing the Internet normally, the billing system of operators will add these traffic-free services to the white list. The websites in these whitelists are what we usually call IP-free. When the billing system detects that the user is visiting the website in the white list or receiving the multimedia message, it will not deduct the fee.
The problem lies in the detection. The detection methods of operators and regions are different and imperfect, which leads to free traffic, different free traffic modes and regional restrictions. So how is the billing system detected? When a user accesses the Internet, he will send a request header to the server, which contains all the interactive information between the network server and the user, such as the visited website, UA, network protocol, host, Cookie, source address, file type and many other information. By detecting the request header, the billing system can distinguish whether the user is visiting a website in the white list or receiving a multimedia message. The billing system detects the request information sent by the user, which comes from the user. That is to say, by customizing this information, the purpose of cheating billing detection and not surfing the Internet can be achieved.
Question 3: What does due diligence mean? Due diligence, also known as prudential investigation, refers to a series of activities that investors and target enterprises conduct on-the-spot investigation and data analysis on all matters related to this investment after reaching a preliminary cooperation intention through consultation. Including financial due diligence and legal due diligence. The survey contents generally include: industry research, enterprise ownership, historical evolution, human resources, market and sales, research and development, production and service, procurement, law and supervision, finance and accounting, taxation, management information system, etc.
Question 4: What do you mean by half current setting and attenuation setting of stepping motor driver, and how to set them? Current is the carrier of motor operation, but voltage also directly affects current. Many people have misunderstandings when using stepping motors, and think that the function of semi-flow is to reduce heating. In fact, the half-current is for the sake of saving electricity. The inferior thermal motor consumes high energy, so it is necessary to control the heating of the motor through static semi-flow. Good motor heating is inherently small (of course, continuous high-speed uninterrupted operation will still generate heat, but half-flow is meaningless), not to mention that products with the same high energy consumption as motor static operation will definitely consider reducing energy consumption.
Application of Half-current of Stepping Motor: 1: For the equipment (most of which have this structure) with small reaction force from objects to stepping motor, please use half-current or even start the motor.
2: For the structure that only the stepping motor can locate the reaction force by self-locking, please select full flow. (Example: Up-Down Transmission Structure)
Attenuation current setting generally does not make much sense.
Many drivers have automatic attenuation current (automatic internal adjustment and protection circuit), only some old drivers have it.
In fact, the current of any electrical component has a decay process. The decay process of other components is instantaneous, so it is ignored. The characteristic of inductance is the ability to prevent the circuit from changing, that is to say, the current in inductance cannot change instantly, so there is a process of attenuation. The principle is that the change of current is due to the change of magnetic flux in the inductance coil, and the change of magnetic flux produces electromotive force in the coil, and the direction of this electromotive force is just the direction to prevent the change of current, that is, when the current becomes larger, the electromotive force is opposite to the current direction, which plays a role in reducing the current; When the current is small, the direction of electromotive force is the same as that of current, which strengthens the role of current. Because of this electromotive force, the inductor has the process of attenuating the current. In the circuit design, corresponding protection measures should also be set to ensure that the inductor can successfully complete this process during power failure, so as to avoid generating instantaneous large current to damage the circuit.
Question 5: What does parallel flow air conditioning mean? Parallel flow is a new type of heat exchanger. The so-called parallel flow air conditioner refers to the air conditioner with parallel flow heat exchanger. The principle of heat transfer comes from microchannel theory.
At present, parallel flow air conditioners are mainly used for special air conditioners, such as automobile air conditioners.
Household air conditioners are rarely used.
Question 6: What does the current regulation rate mean? Current regulation rate SI is a main self-index reflecting the load capacity of DC regulated power supply, also known as current stability coefficient. Represents the ability of DC regulated power supply to suppress the fluctuation of output voltage caused by the change of load current (output current) under the condition of constant input voltage. Under the condition of specified load current change, the current regulation rate of DC regulated power supply is usually expressed as the percentage of output voltage change value under unit output voltage.
Question 7: What does due diligence mean? Hello, classmate, I'm glad to answer your question!
Due diligence due diligence 1. Investigate or review possible investments. Due diligence aims to confirm all the important facts involved in the sales project. Generally speaking, due diligence refers to the investigation action that a rational person should take before signing an agreement or trading with another party.
