金属化合物热容计算公式

THE EXPERIENCE CALCULATING FORMULA OF HEAT-ABSORPTION CAPACITY OF METAL COMPOUNDS

建立计算金属化合物热容经验公式 :lg (Cp/a) =1 390 +0 0 0 1(x - y)。式中a为原子数 ,x为电子浓度 ,y为两元素在周期表中周期数之差。用此式计算 4 7个金属化合物的常温热容 ,计算值与实验值平均相对误差仅为 2 3%。

The experience calculating formula of heat - absorption capacity of metal compounds can be established.The formula:lg( C p/ a )=1 390+0 001( x+y ), in which a is atomicnumber, x is density of electron, y is difference of period number between two elements in the period table.Heat -absorption capacity of common temperature of forty - seven metal compounds can be calculated. The result difference is 2 3 percent between calculated and experience values.
