鲍尔公式法的改进和热过程计算方法的评价

Modification of Ball's Formula Method and Evaluation of Various Thermal Process Calculation Methods

本文对鲍尔公式法作了改进。改进是通过更正鲍尔公式中的错误实现的,改进后的鲍尔公式法的精确度作了检验。作为对照,原鲍尔公式法,以及国际上常用的其他一些方法包括Stumbo方法,Hayakawa方法,计算机方法等的精确度也作了检验。发现改进后的鲍尔公式法的精确度较原鲍尔公式法的精确度提高了二倍至五倍。Stumbo方法有较大的正误差。Hayakawa方法有较好的精确度,在所有的方法中,计算机方法有最好的精确度。

Ball's formula method has been modified. The modification was completed through correcting the error in Ball's formula. The accuracy of modified Ball's formula method has been examined.In contrast the accuracy of original Ball's formula method, and the other methods used frequently in the world including Stumbo's method, Hayakawa's method, computer method etc have been examined. It has been found that the accuracy of modified Ball's formula method increased by 2 to 5 times in comparison with original Ball's formula method, Stumbo's method had serious positive error. Hayakawa's method had better accuracy. In all of methods, computer method had the best accuracy.
