Because on the turnplate axis power is by the turnplate under after the bevel gear commutation, decelerates transmits, moreover their velocity ratio is 6, also because the bevel gear velocity ratio is not bigger than 3 generally, therefore has designed two axes, by realizes the bevel gear two commutation, decelerates.

因为转台上的轴动力是由转台下经锥齿轮换向、减速传来的，而且它们的传动比为6，又因为锥齿轮的传动比一般不大于3，所以多设计了两根轴，以实现锥齿轮的两次换向、减速。

The velocity field and the velocity equation of the slip surface family may be used to establish a new ultimate analysis method-Generalized Limit Equilibrium Method.

In view of undeterminable parameters andinadaptability to both gas and liquid in existing acoustic velocity models,a new sound velocity model based on PREOS has been established by analysing relationship between pressure,speed of sound and temperature.

针对目前声速模型存在参数难以确定，不能同时适用于气液两种相态等问题，通过分析压力、声速及温度三者的关系，基于PR状态方程开发了声速的新计算模型。

Seepage velocity smoothly change from a steady value to a new steady value, the ratio of the new steady value over the original steady value might increase hundreds of thousand times or even more, but it is always finite.（3）Water-inrush goes with the failure of rock strata, but seepage velocity can not increase unendingly, so seepage flow cant be unstable.

研究表明：由于非Darcy流β因子恒为正值，渗流系统总是稳定的；当渗透特性随时间变化时，渗流速度从一稳定值平滑地过渡到一新的稳定值，新的稳定值与原稳定值之比可以增大到几万至几百万倍，但是总是有限的；突水是岩层结构破裂引起的渗流速度快速或急剧变化，但渗流速度不可能无止境地增大，即渗流不可能失稳。

This gradient thermal field has increased the flow velocity in uniform cross-section channels but can not do it similarly in diverging channels,so that the outlet velocity and volume flow rate have decreased by 16 % and 60 μ l/min,respectively.
