Effect of acidity of aqueous phase and different ammoniation rates of extractant on the total mass transfer coefficients based on the water phase have been investigated The results showed that the mass transfer coefficients of Zn and Cd decreased but that of rare earth increased with the increasing of the ammoniated rate of extractant.

考察了料液酸度、萃取剂浓度以及萃取剂不同氨化度对锌、镉传质系数的影响。

The Cd~(2+) exchange in analcime is enhanced as the temperature increases.

本文还考察了方沸石对模拟废水中Cd~(2+)的去除效果。

The ion exchange capability and application of analcime and Cd~(2+) were investigated which offer directive theory for exploitation and utilize of analcime.

本论文主要研究了合成的方沸石与重金属Cd~(2+)的交换性能及其应用，对方沸石的开发和利用具有重要的理论指导意义。

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

We found that it can form stable structure in appropriate conditions and it exhibits an anomalous CD spectra.

该序列在适当的条件下能形成稳定的复合物，并表现出非同寻常的圆二色D谱。

This clearly indicates that the negative value of dρ/dT in CdYb QCs is mainly due to the quasiperiodicity because these QCs are stoichiomeric compounds with a very narrow single phase range. Positive dρ/dT and anomalously large MR reported previously are found to be due to the existence of free Cd in the samples.

这清楚地显示CdYb准晶的负电阻温度系数是由於准周期导致，因为CdYb准晶是一种单一相范围极窄的当量化合物，以前的研究说其具有正的dρ/dT和异常巨大的磁阻是由於样品中含有金属Cd。

Convolutional differentiator is obtained by inverse Fourier transform of bandlimited Fourier spectra of partial derivative operator. CD is symmetric or antisymmetric and decays rapidly.

褶积微分算子是将偏导数算子的带限傅氏谱进行反傅氏变换得到的，具有对称或反对称和衰减速度快的特点。
