This paper designs shielding and guarding for the circuits, aimed to enhance the stability and reduce error. At last, this paper calibrate the system is using autocollimator and 12 edge glass, and gives the position error, repeatability and acceleration feature.

最后，本文对设计的测角系统进行了实验测试，实验和分析结果表明，本课题所设计的测角系统，其位置精度、测角重复性和加速度性能均满足系统设计要求。

Methods The clpE-deficient strain was constructed by LFH-PCR and identified by PCR and sequencing. The impact of clpE mutant on the virulence of S. pneumoniae was evaluated in a mouse model. In addition, we also studied the effect of clpE mutant on adherence and invasion of host cells. Real time RT-PCR was used to measure the mRNA expression levels of autolysin A, pneumococcal surface adhesion A, pneumolysin, pneumococcal surface protein A and neuraminidase The clpE gene was replaced completely by erm cassette.

用长臂同源多聚酶链式反应方法失活clpE基因，用PCR、测序鉴定缺失菌株，通过动物实验观察clpE基因缺失株毒力改变情况，同时用细胞实验比较clpE基因缺失株和野生菌对宿主细胞的粘附和侵袭能力，最后用实时荧光定量PCR分析自溶素(major autolysin A，lytA)、表面黏附素A(pneumococcal surface adhesion A，psaA)、溶血素(pneumolysin，ply)、肺炎球菌表面蛋白A（pneumococcal surface protein A， pspA和神经氨酸酶（neuraminidase， nanA）的表达。
