The brushless permanent magnet automobile a. c. generator has the advantages of high reliability, long service life, high efficiency, good performance at both low and high speed, low radio interference, simplifying its associated voltage regulator, cutting down materials, technology simplified, as well as high power/weight ratio, etc.,and will be a new product with broad prospects and large market.

无刷永磁汽车交流发电机由于取消了碳刷、滑环及励磁绕组，可大大提高可靠性，延长使用寿命，具有效率高，低、高速性能好、无线电干扰小，与之匹配的电压调节器结构简单、节约原材料、工艺性能好、比功大等优点。

Much of the public first learned about radio in the wake of a tragedy: When the luxury liner Titanic struck an iceberg in April 1912, the doomed ship used the new technology to desperately call for help. Only about 700 of the 2,220 passengers were rescued, but the number of survivors might have been much lower if other ships had not arrived when they did.

大部分人意识到无线电通信是从一个悲剧开始的。1912年四月，豪华邮轮泰坦尼克号撞上了冰山，在新技术的帮助下，它发出了最后的求救信号，2200乘客中只有700人获救，但是如果其它船只不收到信号赶过去，获救的人会更少。
