丹栀逍遥散配合心理干预治疗艾滋病抑郁症60例临床观察

目的:探讨和研究丹栀逍遥散配合心理干预治疗艾滋病抑郁症患者的临床效果。方法:采用口服丹栀逍遥散治疗30例,并予应用HARRT药物和常规对症治疗的30例进行对照观察,两组疗程均为8周。结果:两组间比较无显著性差异(P>0.05),但两组治疗后汉密尔顿抑郁量表(HAMD量表)评分均较治疗前改善(P<0.05),且治疗后的治疗组评分低于对照组(P>0.05)。结论:治疗艾滋病抑郁症应用丹栀逍遥散配合心理干预有良好的疗效。     

Structure characterization for the geopolymer of sodium silicate and metakaolin

1 Introduction 1 During the last decade a new kind of material called geopolymer has emerged as a viable alternative for many conventional cements and plastics. Geopolymer is inorganic polymer derived from metakaolin and sodium silicate solution. It can be synthesized at low temperature and have useful properties such as high compressive strength. It is stable at temperatures up to 800 °C and even 1150 °C while ordinary Portland cement loses its strength at 500 °C [1]. Several microstruct…     

碳纳米管修饰电极在酸性溶液中对NO2-的检测

在载有Os(bpy)3 2+的碳纳米管粉末微电极上,第一步及第二步还原平台电势上,NO2-离子检测的灵敏度及温度系数分别为5.7 A·cm-2·mol-1和6.8 A·cm-2·mol-1及0.16%/℃和0.14%/℃.检测限为10-7 μmol/dm3.拥有如此高的灵敏度和很低的温度系数,使这种粉末微电极将是制备高性能亚硝酸根检测器的良好探头.

Ba2CaB6O12：Eu^2＋蓝色荧光粉的高温固相反应制备与光谱性能研究

采用高温固相反应法合成了含Eu^2＋的硼酸盐蓝色荧光粉,测量了该荧光粉的真空紫外（VUV）及紫外（UV）激发光谱和相应的发射光谱．研究结果表明,在真空紫外和紫外光激发下Eu^2＋离子在该基质均呈现f→d的宽带跃迁,其峰值位于437nm和467nm处,分别对应于基质中Ba^2＋和Ca^2＋格位上的Eu^2＋离子．在真空紫外区域160nm和200nm附近,有两个弱的窄带,来自于基质里BO3^3-基团和Ca—O的吸收,基质和激活离子之间存在着能量传递。

微米铜粉在润滑脂中摩擦学性能的考察

通过四球试验,考察了微米铜粉在润滑脂中的摩擦学行为和抗磨性。试验结果表明：在适当百分含量范围内和载荷条件下,润滑脂中加入铜粉可以提高脂的抗磨性。对钢球磨斑表面形貌分析,添加微米铜粉的润滑脂的磨斑表面要比基础脂的磨斑表面光洁许多。     

When Glass and Metal Corrode Together,V: Sodium Copper Formate

A sodium copper formate, first described in 2002, can also form on copper alloys with sodium originating from soda glass hydrolysis. The frequent occurrence (50% of 250 cases of glass-induced metal corrosion) is due to the presence of formaldehyde emissions in storage and its direct reaction to formate in the alkaline surface films. The compound can be produced without the presence of acetate when chalconatronite or metal coupons immersed in soda solution are exposed to formaldehyde vapours. The crystal structure, derived from X-ray powder diffraction, yielded the sum formula Cu₄Na₄O(HCOO)₈(OH)₂·4H₂O. Except for the absence of acetate in the structure, this is in good agreement with the 2002 publication. To assess which kind of combined glass/metal objects are affected, a number of large museum collections were surveyed. Sodium copper formate was detected as a corrosion product using mainly micro-Raman spectroscopy, for instance, on 18 painted Limoges enamels, eight glass vessels with metal mountings, glass beads on metal wire from 11 bridal crowns, nine Christmas tree balls with wire decoration, 40 pieces of jewellery with glass gems, three daguerreotypes, and one miniature with cover glasses.
