It is during these seasons that the differences in temperature between warm and cold masses of air are greatest 就在这些季节里,热气团与冷气团的温差最大。
Think about : why is the difference in temperature on the earth ‘ s surface not so big as that on the moon ' s surface 想一想,为什么地球表面的昼夜温差远不如月球表面大?
Currents of flowing liquid are caused by the difference in temperature between the top and the base of this zone 流动的液态流是由这个流体带顶端和基部之间的温差引起的。
The major reason of coming into being crack is the temperature shrinking stress by bringing of difference in temperature 由内外温差引起的温度收缩应力是致产生裂缝的主要原因。
Therefore well controlling of difference in temperature and temperature strain are important measures on concrete cracking control 因此,控制好内外温差和温度变形是防止大体积混凝土出现裂缝的重要方法。
