  1. The calculation formulas for velocity coefficients 2 and 5 for the throat and throat inlet section were deduced from the theoretical research on the velocity coefficients in time - averaged basic equations by use of the unsteady momentum equation and time - averaged value calculation method

    摘要運用非恆定的動量方程和時均值計算方法，對脈沖液體射流泵時均值基本方程中的流速系數進行了理論研究，推導出了喉管和喉管進口段流速系數2和5的計算式。
  2. Better agreements between computation results and experimental data were found using the models. ( 4 ) two phenomena in straight - convergent - divergent - straight microchannels were identified, which are different from the macroflow through experimental studies. one is that the first appearing sonic point position in microchannels is not near throat cross - section

    （ 4 ）對等直收縮擴張等直微管道中氣體流動的實驗研究發現兩個特異現象：其一為微管道內最早出現聲速點的位置不一定在喉部附近，其二為微管道中的臨界壓比與常規值有很大差別。
