We reviewed all skin lesions in all HIV patients diagnosed in our department between 1990 and 1998 to document the spectrum of skin manifestations, the frequency of each disorder, and their relationship with CD4 counts. A total of 64 HIV patients were studied, including 38 with acquired immunodeficiency syndrome CD4 200 x 10(6 cells/L and 26 who had not developed AIDS. There were 142 episodes of skin conditions representing 25 different skin diseases, including oral candidiasis (15% in non-AIDS vs 71% in AIDS patients), drug eruptions, herpes simplex, seborrheic dermatitis, dermatophytosis, herpes zoster, secondary syphilis, condyloma acuminatum, Kaposi's sarcoma (16% among AIDS patients), hairy leukoplakia, and molluscum contagiosum (13% among AIDS patients), in decreasing order.

In order to study the composition segregation region s in bulk metallic glass,small angle X-ray scattering technique and differential scanning calorimetry were used to investigate the evolution of microstructure in Cu55Zr30Ti15 amorphous alloy heated from 310 K to 783 K.

为了研究大块非晶合金中成分分离区的存在状态及其在晶化过程中的作用，应用小角X射线散射技术和差示扫描量热仪研究Cu55Zr30Ti15非晶合金从310 K到783 K之间微结构的演化情况。

It is very difficult to eliminate these influence factors completely by conventional treatment. Surface properties and surface treatment of ultrafine red phosphorus and MMT and their interface properties with polymer matrices were studied in this thesis. The results were characterized by GC, FTIR, XRD, DTA, TG, XPS, UV, SEM, TEM and other physical and chemical methods. The main contents are as following: 1. The study of factors influencing ultrafine red phosphorus's invariability and phosphine liberation indicated red phosphorus undergone oxidation and dismutation reaction in air, and trace ion of iron, copper and nickel fastened water absorption and oxidation, in which the effect of copper ion was the most, while aluminium and zinc ion could slow down red phosphorus'oxidation, and silver ion had the best effect on red phosphorus moisture absorption. Inhibitors such as aluminium hydroxide, magnesium hydroxide, organic phenol and ferrous potassuim cyanide had a good effect on reducing red phosphorus moisture absorption and restraining phosphine liberation.

本文围绕纳微米材料的表面处理及其在高聚物基体中的应用这一主题，系统地研究了超细红磷和蒙脱土两种常见材料的表面特性、表面处理方法及其与高聚物基体的界面特性，通过气相色谱、红外光谱、X射线衍射、差热、热重、X射线光电子能谱仪、紫外光谱、扫描电镜、透射电镜等现代分析仪器以及其它物理、化学方法对实验结果进行了表征和分析，全文主要内容如下： 1、对影响超细红磷安定性的因素以及磷化氢的缓释研究表明：红磷在空气中发生缓慢氧化、歧化反应，微量的铜、铁、镍等金属离子增加了它的吸水和氧化速度，其中铜离子的作用最为明显，而铝、锌等离子减慢了红磷的氧化速度，银离子对减少红磷的吸湿性效果最好。
