| 摘 要： | ＾１３４Ｃｓ在海水－底质系统中的转移遵循一级反应动力学模式，盐度能抑制底质对＾１３４Ｃｓ的吸附率；海藻能迅速累积海水中的＾１３４Ｃｓ；盐度对海洋生物累积＾１３４Ｃｓ有明显的影响，这种影响可用指数函数来表达。

| Abstract: | It was found in this study that the variation of 134 Cs in the sea water substrate system follows the model of first order reaction kinetics. The salinity can inhibit the adsorption rate of 134 Cs by substrate. Marine algae can fast accumulate 134 Cs from the sea water. The salinity can obviously effect the accumulation of 134 Cs by marine life. The effect can be described by an exponential function. Because of the antagonism, the distribution of 134 Cs was not even in the ecosystem. The substrate can adsorb about 40% radioactivity and the marine lives can only accumulate 1%. |
