速水流

其次对泥沙沉速计算、水流挟沙力和恢复饱和系数的取值等问题进行了探讨并提出了合理的解决办法，在此基础上对现有的泥沙数模学型进行了改进和完善。

Then several problems are discussed and proposed the reasonable solutions , such as the calculation of the silting velocity of sediment , the sediment transport capacity , the coefficient of sediment resume saturation , etc. On the basis of these discussions , the mathematical model is improved .

通常采用泥沙的静水沉速，以计算水流的挟沙能力，在理论上是不合适的。

The current practice of estimating the silt-carrying capacity of channel flow by the use of the settling velocity of suspended sediment in still water is theoretically unreasonable .

结论由恒速灌肠器提供的脉冲恒速高压水流能够用于肛门直肠控便功能的评估，恒速灌肠法具有客观、即时、定量的优点。

Conclusion Fecal incontinence could be evaluated with the speed-constant rectal lavage apparatus , which yields objective and quantitative results .

结果实验室制备的恒速灌肠器能够输出足以克服直肠任何阻力的脉冲恒速水流（可以调试为标准速度1ml/s）。

Results The device could output a pulsed and speed-constant water stream with high pressure , capable of overcoming any rectal resistance change .
