用一管孔连结的两水箱,计算和实测的振动水面的升降值表明,一维解答可准确地预告孔口对振动的阻尼和增量效应。前者主要是增大振幅衰减,后者加大振动周期。
The calculated and measured vibrational water surface lift values show that one-dimensional solutions accurately predict orifice damping and incremental effects on vibration. The former mainly increases the amplitude attenuation, the latter increases the vibration period.
