Then the relationship among vibration frequency of the plate in water and that in vacuo and the Nondimensionalized Added Virtual Mass Incremental (NAVMI) is obtain by utilizing Rayleigh method.
进而应用瑞利方法得到了薄板水中振动频率与真空中振动频率、无量纲附加虚质量增量之间的关系。
The dioxane solution was concentrated by evaporation and the remaining oil was distilled in vacuo on a water bath.
在二氧六环的解决办法是通过蒸发浓缩和剩余油是在真空中蒸馏水上热水澡。
Moreover the vibration frequencies of the plate are computed using iterative method, which begins with the in vacuo eigenfrequency and continues until in-water eigenfrequency con-verges.
从真空中模态特征频率出发用迭代法直到水中频率收敛为止而得到水中方板的特征频率,进而计算了方板的棤态辐射效率。
