Nonetheless Edison offered him a job, promising Tesla fifty thousand dollars if Tesla could redesign Edison's breakdown-prone DC generator designs.

尽管如此，爱迪生还是给了他一份工作，并向特斯拉承诺， 如果特斯拉能够重新设计爱迪生容易发生故障的直流发电机设计， 他将获得五万美元的报酬。

There are DC generators, which include special parts to make the current keep flowing in the same direction the whole time, instead of reversing itself as the coil turns.

有直流发电机，其中包括特殊部件，使电流始终沿同一方向流动，而不是在线圈转动时自行反转。
