求物理生中译英.水在0-4度时,热缩冷胀,4度以上,就热胀冷缩了.所以0-4度时,表面张力随温度升高而升减小.4度以上时,表面张力随温度升高而升高.当然管径越越大,表面张力越小.流速越大,表

When water ia at around 0-4 degrees, heat(things) shrinks, cold(things) expansions, so when it's around 0-4 degrees,surface tension decreases as the temperature increases.When it's above 4 degrees, the surface tension increases as the temperature decreases. Of course, the greater the diameter, the smaller the surface tension. The greater the velocity, the greater the surface tension.
