计算密度 meaning in Chinese

bulk density

This paper introduces two methods of computing density and enthalpy : combination of " sectional average value " and " look - up tables " will improve the temperature resolution to 0 . 1 , that is / 0 . 1 and h / 0 . 1 ; " mathematical simulation " method will get density and enthalpy value with error less than 0 . 01 %
在本文中，提出了两种计算密度值和热焓值的方法：用“区间平均值法”与查表法相结合，来求密度值和热焓值，可将求的密度值和热焓值所对应的温度分辨率，提高到0 . 1 ，即0 . 1 、 h 0 . 1 。
