Fitting Of Relational Expression Of Saturated Vapor Pressure And Temperature Of Water By Multiple Regression

Keyword:  回归拟合水的饱和蒸气压温度;
Abstract: 在使用于湿球测定锅炉烟气含湿量的过程中,需要查找水的饱和蒸气压,非常不方便.利用D-196和<化工原理>上册中取得部分数据,用多次线性回归的方法,拟合出水在0~200℃范围内的饱和蒸气压与温度的关系表达式;并对该表达式的误差进行了分析,误差均值为0.2‰,最大值也只有0.8‰,完全可以满足环境监测中数据处理的精度要求.
