摘要: 两端支承管道中流体的临界速度,可从该管道横向振动偏微分方程求解得到·本文从分析管道琴于发散失稳状态时的能量关系,较简便地求得各种支承情况下管道中流体第一临界速度的统一公式,并与其他公式进行比较,结果相近。

Abstract: The critical velocity of fluid in a pipe supported at its two ends can
be obtained by solving the partial differential equation of the pipe's late-
ralibration .By analysing the relation of energy to the pipe's divergent
instability,a unified form ula for the velocity has been derived.The results
obtained by the formula are very close to those got by other formulas.
