珠江口表层水中Alk,K^+,Na^+,Ca^(2+)运移过程的稀释规律

The Dilution Pattern of Alk,K ~ +,Na~ +,Ca ^(2+ ) in the Transfering Process of Surface Seawater Samples of Zhujiang Estuary

１９９４ 年９ 月１ 日～１１ 日采集珠江口表层海水水样。利用模拟水样和现场水样稀释比与化学要素浓度关系的数学模式，对珠江口表层水Ａｌｋ ，Ｋ＋ ，Ｎａ＋ ，Ｃａ２ ＋ 在运移过程的稀释规律进行了研究，并利用上述模式计算了珠江口表层水样的Ａｌｋ ，Ｋ＋ ，Ｎａ＋ ，Ｃａ２ ＋ 在河海水整个混合过程和相应于各稀释比条件下的转移量。

Surface sea water samples in the ZhuJiang River estuary were collected during September 1 to 11, 1994. The dilution pattern of Alk,K +,Na + and Ca 2+ during the migration of the surface water was investigated by a mathematic model based on the relationship between the dilution ratios (of the simulated water samples and water samples collected in situ) and the concentrations of chemical elements. The transfer fluxes of Alk,K +,Na + and Ca 2+ in the surface water corresponding to different dilution ratios during the whole mixing process (of the river sea waters) are calculated using the same model.
