活泼元素 meaning in Chinese

active element

Comparison of the characteristic parameters of immobile elements , such as ree , sc , th , ti etc and of the characteristics of sedimentology and mineralogy comes to a conclusion that the provenance of the sediment is different in the last glacial maximum and in the sub - interglacial stage , and they have the traits of mixed source . during the last glacial maximum the sediment in the outshelf of the southern east china sea was affected weakly by changjiang river and they are probably derived from the coast mountains of zhejiang - fujian province , which are near the southern east china sea
通过对东海外陆架样品的稀土元素和sc ， th ， ti等不活泼元素地球化学物源示踪指标对比，再结合沉积学和矿物学特征，判断末次盛冰期与盛冰期以前的沉积物具有不同的物质来源，不同时期的沉积物都具有混合物源的性质，盛冰期东海南部外陆架沉积物受长江物源影响较小，可能来源于距东海南部较近的浙闽沿海山地。
