However,the European,with deeply rooted tradition of atomic theory,stuck to the principle of positivism.

可是 ，具有根深蒂固原子论传统的欧罗巴人，信守逻辑实证主义的思维原则，在人体解剖实验的基础上，利用还原分析和实验求证的方法，使古希腊医学从思辨走向描述和结构时代，这是顺乎逻辑的自然发展。

The platform designing that the photoelectricity sensor tests the instrument experiment this time adopt CSY-998G , the system making use of the photoconductance effect to be one kind of body effect of semiconductor materials , building an experiment, test photosensitive audion waiting for photosensitive transistor volt-ampere characteristic property.

此次设计采用CSY-998G光电传感器试验仪实验平台，利用光电导效应是半导体材料的一种体效应，建立实验系统，测试光敏三极管等光敏晶体管的伏安特性。

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。

This paper introduces a software experiment platform for time domain analysis of second-order system in experimental teaching of automatic control theory.
