f 9 7 Z—Z 9男一Z 我国对减速顶及其调速技术的研究已经十年了,让我们通过这些镜头来描绘我国十年来减速顶调速技术发展的一个轮廓吧! 图片说明: 1.我国首先研究采用减速顶调速系统的就是这个哈尔滨站下行场,1979年在这里创造了我国第一个减速器与减速顶结合的点连式方案。 2.
It has been 10 years since our country started to research on the deceleration top and its speed control technology. Let us use these shots to depict a profile of the technological development of speed domestication in our country over the past decade. Photo caption: 1. China first studied the use of deceleration top speed control system is the Harbin Railway Station downlink field, here in 1979 to create China’s first reducer and deceleration top combination of point-connected solutions. 2.
