内燃机现场环境状况下饱和蒸汽压的曲线拟合

介绍了用最小二乘法拟合方法 ,将内燃机现场环境状况下饱和蒸汽压表示为多项式形式 ,为计算功率和燃油消耗率校正系数 ,并为此而编制计算机程序提供方便。

Saturation vapour pressure of internal combustion engine under actual operation conditions is expressed as the multinomial by using least square method, which facilitates the calculation of rectifying coefficient of engine output and fuel consumption as well as the fabrication of computer programme for such calculations. The practicability of method has been verified by calculations.
