离子交换

A monomer, trithiocarbonate anion is successfully"immobilized"onto the polymeric support by reaction of CS〓 with strong-base quaternary ammonium in anion exchange resin with OH〓 form.

研究了把CS〓离子固定到阴离子交换树脂上，以及它在CS〓悬浮体系中和另一单体，α，α'-二溴代二羧酸甲酯在阴离子树脂表面上进行的亲核取代反应。

In addition, a series of analyses about theoretical principles of HMI removal by WBAER from DK with alkali metals, alkaline-earth metals and anions at high concentration and regeneration of WBAER, have been analyzed.

同时本文还对弱碱性阴离子交换树脂从高背景的常规阳离子和阴离子中有选择性地去除饮用水中微量重金属离子及其再生的机理进行了一定的探讨。

The cation resin used in softeners is easily contaminated by iron ion.

软化器中使用的阳离子交换树脂容易受到铁离子的污染。

However, the results of the previous works about the first-order phase transition are confused and even contradict each other.In this paper, the properties of the phase transition in the transverse spin-2 Ising model with different single-ion anisotropies are studied employing mean-field theory and correlated effective-field theory.

目前，研究最活跃的是所谓的Blume-Capel模型(简单记为BC模型，是只考虑线性交换作用和单离子各向异性的Ising模型)及其扩展模型(引入横场的BC模型和引入无序的BC模型)，但关于BC模型及其扩展模型的一阶相变的结果还很模糊。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
