摘要
本文描述了使用最小二乘法原理 ,推导出两种工况下的过热水蒸汽比容近似公式 ,其精度高 ,误差小 。
This paper describes the use of the principle of the least square method to derive an approximate formula for calculating the specific volume of superheat steam under two working conditions.This formula can yield a high accuracy and a small error,which is of considerable reference value for improving the measurement accuracy of the steam flow.
