由红外光谱和气相色谱法测得天然丰度原料的含氢化合物的解离速率较含氚化合物的解离速率小约10~4倍。
Our results measured by IR spectrum and gas chromatography show that the dissociation rate of hydrogen compound in natural reactant is anbot 10~4 less than deuterium compound.
水位随季节周期性消落，将导致水体相和沉积物相中的总汞浓度按枯、丰、平顺序依次递减。
As the result of seasonal fluctuation of water, the total Hg concentration of water and sediment would be degressive in sequence of low water, flush time and ordinary level.
