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 soldering qualities of radiating fin are increased by adding mg spalls in vacuo soldering furnace.
通过跟蹤试验,在真空钎焊炉内加入镁屑,解决了质量问题,提高了散热片的钎焊成品率。
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。
the area of peak 3 increased by 1.90-and 5.74-fold, respectively, after drying in vacuo and under atmospheric pressure.
与干燥前相比,减压干燥和常压干燥使3号峰面积分别增加了1.90倍和5.74倍。
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.
