The amount of soil aggregateon solonetz was 16.5% only,but after improving,it can reach 32.55%.

碱土团粒结构则更少,仅为16.5%,但经化学措施改良后也可达到32.55%。

This review summaries the application of ion exchangers in the separation and determination of alkali metals, alkali-earth metals, noble metals, rare earth elements and actinoid.

离子交换取色谱中得到了广泛应，本文详细总结了离子交换分析化学中于碱属、碱土属、贵属、稀土元素、锕系元素等分离与测定。

When two different metals are placed in a fused alkali or alkaline-earth chloride bath, the more readily corrodible metal will deposit on the less corrodible one.

当两种不属放熔融碱属或碱土属氯化物盐浴中时,较易腐蚀属会沉积较难腐蚀属上。
