目前随着行业的改变，发电机租赁迎来黄金时代，作为基于法拉第电磁感应定律而来的设备，即一块金属，比如一根铜线，在磁场中运动，金属内部会产生电场。

　　With the changes in the industry, generator leasing has entered a golden age. As a device based on Faraday's law of electromagnetic induction, a piece of metal, such as a copper wire, moves in a magnetic field and generates an electric field inside the metal.

　　金属内部的电荷就会沿着电场流动。如果这块金属不是一个环，电荷就会积累在两端，以电压的形式存在，把这块金属接在一个回路中(回路除金属以外的其他部分并没有在磁场中)，就产生了电流，于是，发电机发出了电。

　　The charge inside the metal will flow along the electric field. If this metal is not a ring, charges will accumulate at both ends and exist in the form of voltage. Connecting this metal to a circuit (other than the metal in the circuit that is not in the magnetic field) generates current, and the generator emits electricity.

　　所以，发电机的基本原则就是固定住永磁体或者是金属，让金属或者是永磁体不停的运动，运动是相对的嘛，这样，那块不停的在磁场中运动的金属就会不断的发电。

　　So, the basic principle of a generator is to fix the permanent magnet or metal, so that the metal or permanent magnet moves continuously and the motion is relative. In this way, the metal that is constantly moving in the magnetic field will continuously generate electricity.

　　由这一点可以区分不同的发电机，水力发电机就是利用水从高处落下的能量维持金属的运动，火电就是利用火烧开水产生的蒸汽的力量维持金属运动。发电机组类型有很多，按照

　　From this point, different generators can be distinguished. Hydroelectric generators use the energy of water falling from a height to maintain the movement of metals, while thermal power uses the power of steam generated by burning water to maintain the movement of metals. There are many types of generator sets, according to

　　总之，发电机租赁对于工程以及公共救援是非常好用的，不同的标准可以划分不同类型的机组，如果你正巧也需要欢迎来我们博达发电机租赁考察。
