改进的变比热平行混合解析解

鉴于原平行混合准确解牵动到物理过程一般并不经过的临界温度的比热值。在变比热情况容易带来不必要误差，文中推导了只动用总静温、并主要依靠静参数的全套改进解公式，从算例结果看出，原准确误差很小，但改进解不仅更为合理，而且是简明快捷的。所以是先进的。

IMPROVED ANALYTICAL SOLUTION FOR VARYING SPECIFIC HEAT PARALLEL STREAM MIXING

In view of the fact that the original varying specific heat parallel mixing accurate solution by the author has utilized the critical temperature actually not experienced by the physical process, which possibly introduces unnecessary errors, an improved set of formulae relying mainly on static parameters is hereby derived.Illustrative examples show that the original accurate solution gives very small errors, yet the improved solution, being not only more rational but also much simpier and quicker, is therefore more advanced.
