besides, a new inequality on generalized logarithmic mean is obtained.
此外,还得到关于广义对数平均的一个新的不等式。
under the same conditions, when the logarithmic mean temperature difference between upstream maximum downstream, the smallest of the mixed flow pattern between the two asked.
在相同工况下,逆流时对数平均温差最大,顺流时最小,混合流型介于二者之问。
improve the heat transfer efficiency of plate heat exchanger is to improve the heat transfer coefficient and key logarithmic mean temperature difference.
提高板式换热器传热效率的关键是提高传热系数和对数平均温差。
by introducing and comparing the already existing mature ets and combining the chinese situation analyzed by logarithmic mean weight divisia(lmd)method, we present a tentative concept of ets in china.
本文通过对成熟排放权交易体系的介绍和比较,再结合对数平均权重分解法分析所得的中国的国情,对中国的温室气体排放权交易体系提出构想。
