【摘要】 运用实验误差理论常用的“最小二乘法”数学技巧，利用ＮａＣｌ室温（ｔ＝２５℃）压缩的实验资料（ΔＶ／Ｖ０～ｐ关系），即Ｎ＝３５个抽样数据［１］，并借助于电子计算机的大量运算，精确地求得推广的Ｂｒｉｄｇｍａｎ型等温压缩状态方程．数值计算的结果表明，得出的物态方程较Ｂｒｉｄｇｍａｎ方程［２］和Ａｎｄｅｒｓｏｎ方程［３］更符合实验结果．更多还原

【Abstract】 In the paper, by minimum two multiply method of the mathematics skill. It used pressure experimental material(ΔV/V 0～p) of the (NaCl) room temperature and did large calculation with the help of the computer, then abtained accurately Bridgman type isothermal pressure equation of state. Calculation results showed: this equation of state agree well with the experimental data.更多还原
