作者：刘昉张昭 college of Chemical Engineering Sichuan University

The adsorption mechanism of Na^＋, Cl^- and other impurities on the surface of basic nickel carbonate was clarified by electric double layer model. Based on the mechanism, a new purification method was studied. The method can be described as washing-drying-rewashing-drying. The experimental results indicate that the process is very efficient to remove impurities adsorbed by the precipitate when using NiCl2 and Na2CO3 as the raw materials. The finished product＇s contents of sodium and chlorine are both less than 0.01 wt%.

采用粒子模拟研究了同轴波导虚阴极振荡器二极管参数对微波效率和频率的影响,得到了由二极管参数改变引起的二极管阻抗变化及其对微波效率的影响规律.借鉴具有慢波结构的高功率微波器件中微波模式特性阻抗的计算方法,给出同轴波导虚阴极振荡器中微波主模式特性阻抗的理论计算公式.将理论计算结果与由粒子模拟对器件进行优化后得到的二极管阻抗进行比较,发现当反映电子束特性的二极管阻抗与微波主模式特性阻抗匹配时,虚阴极振荡器具有较高的束波功率转换效率.进一步用特性阻抗对其他几种典型结构的虚阴极振荡器进行分析,验证了该方法的合理性,为设计高效率虚阴极振荡器提供了理论指导.

根据分子动力学理论建立了液态锌铝合金ZA27的模型,结合计算机编程构造出了ZA27合金相与液相共存时的原子结构模型,利用Recursion方法计算了稀土固溶于晶粒内和富集于晶界前沿时的电子结构。由此得出:稀土处于相界区比在晶内更稳定,从而解释了稀土在相内溶解度很小,结晶时富集于相界前沿液体中的事实;稀土处于液态和晶态的结构能差相对于铝较大,解释了稀土在晶界前的富集使晶枝产生熔断、游离、增殖的观点。原子间的键级积分计算也表明,稀土处于晶界前沿液体中与铝相比不容易结晶到晶体表面,起到阻碍晶粒长大,细化晶粒的作用,这就从电子层次解释了稀土的变质机制。

The expression levels of heat shock protein 70 (HSP70) from peripheral lymphocytes of the patients with allergic rhinitis (AR) and the clinical implication were investigated In the morning, 3 ml of fasting venous blood was taken out The lymphocytes were isolated by using Ficoll-Hypaque and the expression of HSP70 in the lymphocytes was detected by using Western blot In the AR patients the HSP70 level (41 49±15 77 integrated optical density, IOD) were significantly higher than that in the control group (23 89±10 13 IOD, P< 0 05) Western blot demonstrated that HSP70 bands in AR patients were more intensive than those in the control group It was concluded that the elevated HSP70 level in peripheral lymphocytes of the AR patients might contribute to the development of AR
