viscousness

1.Preliminary analysis shows that the propulsion force is relative to serval factors, such as liquid viscousness, drive fin wet area and offset, etc.

分析表,微机器人推进力与流体的粘性系数、摆翼面积和偏移角等因素有关。

2.After experimental data processing, material's viscousness coefficient was acquired and a new method to determine fatigue limit by the threshold of plasticity energy dissipation was given.

通过试验数据的分析，求出了的黏性系数，给出了利用塑性能耗的起点确疲劳极限的方法。
