divalent ion meaning in English
二价离子
二阶离子
Examples
- The chemical analysis of the soil extracted solution has shown that the soluble salt in the soil is predominated by the divalent ions ca2 + and mg2 + which mean that the soil aggregates have been chemically stable during the field experiment
同时，对土壤浸剂液的化学成分的分析结果表明，浸提液中二价的钙、镁离子占优势，这使土壤微团聚体处于一种化学稳定的状态。 - More recently , the perovskite manganite compounds , la1 - xsrxmno3 have been used as the cathode of the solid oxide fuel cell ( sofc ) because of their electro - ion conductivity properties . in manganite perovskites , substitution of divalent ions ( alkaline earth metals viz
近几年来， la _ ( 1 - x ) sr _ xmno _ 3这类钙钛矿型结构的氧化物材料因为其具有混合电子-离子导电特性而被广泛的应用于固体氧化物燃料电池阴极材料。 - Though zn 2 + and co 2 + are divalent ions , they probably can not substitute ca2 + from the active center of tcs , or can substitute ca2 + but does not change the structure of tcs . there is no significant change observed for the fluorescence intensity of tcs
‘ “是二价金属离子，但这两种离子与天花粉蛋白作用时可能并没有取代天花粉蛋白活性部位的ca ‘ ” ，或部分取代但并没有改变天花粉蛋白分子的空间结构，以致天花粉蛋白的荧光强度无明显变化。 - In manganite perovskites , substitution of divalent ions ( alkaline earth metals viz . ca , sr , ba ) in the a sublattice , introduces mn4 + ions or holes into the system . it is generally considered that the concentration of holes is equal to the concentration of divalent cations because of the charge compensation by controlled valencies
在类钙钛矿型晶体结构中通过掺入二价碱土金属(如ca ， sr ， ba )可以在系统中产生mn ~ ( 4 + )或氧空位，由价格补偿的原理，理论上掺入的二价离子的浓度和氧空位的浓度相等。
