有齿轮的

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。

In fact, there is little pump of the fluid loss, which makes the operation of pumps can not achieve 100% efficiency, as these fluids are used to on both sides of bearing and gear lubrication, and the pump body is also not possible with no gap, it can not be so that 100% of fluid discharged from the export, so a small amount of fluid loss is inevitable.

实际上，在泵内有很少量的流体损失，这使泵的运行效率不能达到100％，因为这些流体被用来润滑轴承及齿轮两侧，而泵体也绝不可能无间隙配合，故不能使流体100％地从出口排出，所以少量的流体损失是必然的。
