It deals with the invention and development of time-keeping apparatus in our country during a historical period of some three thousand years, tracing this development from remote antiquity with its sundial and clepsydra making use of the shadow of the sun down to the Dynasties of Han, Sui, Tang and Sung with their water-powered astronomical clockworks...

自远古利用日影的圭表和日晷起，中间经汉、隋、唐、宋等朝代，附装在水力天文仪器上的水力天文钟，都采用了齿轮和凸轮的传动，即已都属于机械性。元代郭守敬以后，到明初的詹希元，更发展到独立时钟机构，並有了指针和表盘。可是近四百年，即自明代万历年间，西洋的自鸣钟传来我国，我国在计时器方面的工作，始终在模制阶段，自己的发明遂归于停顿。那次会议闭幕以后，会中曾用英文出版一次，我国1956年12月，《天文学报》4卷2期用中文出版一次。现在根据一些新资料，重新加以增删和改正。

When other technics conditions are certain, we use the globosity aluminum powder of different particle diameter a to grind the flake of aluminum powder , with the particle diameter increase of the globosity aluminum powder, the particle diameter of the flake of aluminum powder will also become bigger immediately. 3, The ratio of grinding ball to aluminum powder is 20:1. 4,the grinding speed is 38 and 33 r.min alternate once h-our in the first 10 hours, and use the speed of 29 and24 per hour alternating revolving speed in the last 5 hours, this speed is fine to grind the flake of aluminum powder. 5, wet method ball-milling mainly adopt of help-milling agent as Bl. 6, influence of the research grinding time.

经系统的研究，得出如下结论：1、基本参数：采用200升球磨机，装入钢球200kg，原料铝粉：溶剂量=1：2，铝粉：钢球=1：20；2、当其它工艺条件一定时，用不同粒径的球状铝粉作为原料磨制片状铝粉，随着原料铝粉的粒径增大，所制得的片状铝粉的粒径也会随之增大。3、球料比我们控制在20：1.4、研磨前10小时采用速38和33r.min每小时交变一次，后5小时用29和24每小时交变的转速，这个速度是适宜磨制片状铝粉的。5、湿法球磨片状铝粉主要采用的助剂为复合助剂B1.6、研究研磨时间的影响。
