Abstract: 用米勒罗(Millero),罔萨雷斯(Gonzalez),沃德(Ward)(1976,Journal of Marine Research,34,61—93)还有波伊森(Poisson),布律内(Brunet),布伦—科坦(Brun—Cottan)(1980,Deep Sea Research,27,1013—1028)在温度0—40℃,盐度0.5—43时进行的密度测量值来确定新的一个大气压海水状态方程。方程的形式如下(t℃;S;ρkgm-3) ρ=ρo+AS+BS3/2+CS2 式中:A=8.24493×10-1-4.0899×10-3t+7.6438×10-5t2-8.2467×10-7t3+5.3875×10-9t4 B=-5.72466×10-3+1.0227×10-4t-1.6546×10-6t2 C=4.8314×10-4 ρo是水的密度(Bigg,1967,British Jonrnal fo Applied physics 8,521—537) ρo=999.842594+6.793952×10-2t-9.095290×10-3t2+1.001685×10-4t3-1.120083×10-6t4+6.536332×10-9t5 方程的标准误差为3.6×10-3kgm-3。联合国教科文组织海洋学常用表及标准联合专家小组已推荐该方程为新的一个大气压海水状态方程。
