Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.

It's actually quite easy to drive a car. The difficult part is to find your way. First you need to learn to drive in reverse. When you drive in reverse the rear-view mirror is not very useful because it can't reflect a large area, so you normally have to turn your head around and look behind.

2其实看车很简单，只不过要认识路是一件很难的事首先你要知道怎么倒车，倒车的时候是用不上后视镜的，因为后视镜不能展现出很大的区域分为，所以在一般情况下都要把头转到后面去看。

Some relative characters of reverse micro emulsions of reacting substance/AOT/iso-octane were studied. The phase graphs of the reverse micro emulsions at different temperatures were drawn. And the charts of relationship between conductivity of the reverse micro emulsions and the solubility of H2O or the solution of RDX in them were also done.
