Effect of blade Angle at exit on energy performances is shown by conducting energy equilibrium test on impellers with different exit blade angles.
通过对不同出口安放角叶轮的能量平衡试验，了解到出口安放角对泵能量性能的影响。

Factors that effect the preciseness of contact Angle measurement are the roughness of the solid surface. The change of temperature and equilibrium time effect the contact Angle slightly.
影响接触角法测定准确的主要因素为表面粗糙度，此外温度变化及平衡时间对接触角也略有影响。
