O形密封圈在光学仪器结构设计中的应用

在光学仪器结构中使用O形橡胶密封圈，具有减少光学零部件压紧附加应力、紧固、防松、密封等功能；据实际情况巧用它，可简化结构、提高标准化程序、减少工序、降低成本。论文介绍了几种应用型式及相应的设计参数。把O形橡胶密封圈应用于光学仪器设计中有一定的推广价值，尤其是文中推介的低、中倍显微物镜的简化结构很有希望能进一步发展成为光学仪器新的典型结构。     

水解酸化-好氧处理光学仪器生产废水试验研究

采用水解酸化-好氧工艺对光学仪器生产废水进行试验研究。结果表明，该工艺可有效地处理光学仪器生产废水。当进水CODcr浓度为530—900mg／L时，水解酸化出水达148—376mg／L，再经过好氧处理后出水可达45～115mg／L，总的CODcr去除率在86．2％以上。明显优于单一好氧处理出水水质。     

Design and Coupled Thermo-Mechanical Analysis of Silicon Carbide Primary Mirror Assembly

Based on the principle that the thermal expansion coefficient of the support structure should match that of the mirror, three schemes of primary mirror assembly were designed. Of them, the first is fused silica mirror plus 4J32 flexible support plus ZTC4 support back plate, the second K9 mirror plus 4J45 flexible support plus ZTC4 support back plate, and the third SiC mirror plus SiC rigid support back plate. A coupled thermo-mechanical analysis of the three primary mirror assemblies was made with finite element method. The results show that the SiC assembly is the best of all schemes in terms of their combination properties due to its elimination of the thermal expansion mismatch between the materials. The analytical results on the cryogenic property of the SiC primary mirror assembly show a higher surface finish of the SiC mirror even under the cryogenic condition.
