nonsteady 中文意思是什麼

nonsteady 解釋
不穩的
  1. It was specially pointed out that, when the tail water is constant maximum tide, the computed flood surface is higher than that of nonsteady current, so there is some safety superelevation. underestimation of the roughness will make downward bias to compute along - river surface and bring hidden trouble for flood control. to improve the section can decrease the water level or offset the water rise for increase of floodplains " roughness, but it need much engineering works

    特別提出，按照恆定流計算出來的設計水位比非恆定水位具有一定的安全儲備；而對于灘地糙率的低估又會造成設計水位的偏低，給防洪工作帶來隱患；如果利用改進斷面形式來降低水位或彌補糙率增加帶來的水位抬高，需要較大的工程量，所以平時應注意灘面的減糙管理工作。
  2. The vapor pressure and heat of vaporization have been shown to be significant properties in nonsteady droplet vaporization.

    在非穩態的液滴汽化中，蒸氣壓和汽化熱是重要的性質。
