Keyword:  海水电导率标准海水电导池低盐度重量稀释温度函数关系海水样品测量值聚四氟乙烯;
Abstract: 在-2℃至35℃的整个海洋温度范围和0至42‰S盐度范围内测量准确已知盐度的海水样品电导率和同温度下标准海水电导率的比值Rs.t.o。盐度S<35‰的海水样品是由蒸馏水准确重量稀释标准海水制备的,快速蒸发标准海水制备高盐度海水样品继而重量稀释到已经确定的<35‰S范围。推导出了非常准确地表示1~42‰S和全部温度范围内的S与Rs.t.o关系式,即 S=f1(Rs.t.o)+f2(Rs.o,t.t)=sum from n=0 to 5 a1Ra/2+△t/(1+k△t)sum from n=0 to 5 bnRn/2式中△t=t-15℃,R=Rs.t.o,只有第一项f1要求15℃。也确定了温度对标准海水电导率的影响,用t的四次方程非常准确地表示温度t时的电导率的比值的rtt(C35.t.o/C35.15.o),即:(?)t=sum from n=0 to 4 Cntn 这两个方程足以满足常压下所有盐度测量。
