Firstly, this article in view of the CATIA CLSF, elaborated this software post-processing way, the operating mode of the three principles, and has given the explanation to this software overall constitution; Secondly, after having analysised and researched thoroughly how the CATIA/CAM module creates the APTSOURCE file and its format, the rules of CNC milling machining center MODIMILL 4L, FIDIA PowerXP20system and the coordinate transformation of the machine tool, we programmed the code of CMSPP special post-processing software and compiled the interface based on the dialog box pattern which the fine outward appearance, is easy to operate; Finally, from machining practice, the NC program by the post-processing program can be run in the machining center to machine the part.

首先，本文针对CATIA刀位文件的特点，提出了该软件的后处理方式以及软件运行的三条原则，并对该软件的总体构成作了阐明：其次，本文对CATIA／CAM模块生成的APTSOURCE文件格式、FIDIA PowerXP20数控系统的规则以及MODIMILL 4L铣削加工中心坐标转换数学模型进行了深入的分析与研究，在此基础上用VC++6.0语言编写了CMSPP专用后处理软件的算法代码，并且基于对话框模式编写了外观精美、易于操作的功能界面；最后，通过实例验证表明：开发的后置处理软件所生成的数控加工程序能够在加工中心上运行并能进行有效地加工。

We select pharmacodynamics index, establish animal model, and carve availability group according to pharmacological experiments. And draw a conclusion that the 60%EtOH extr. is availability group. In this group, 15 compounds have been isolated, 13 are identified, 6 are the first isolation from Galium verum L., 2 are the compounds that no document reports. Most of the compounds are flavonoids, others are organic acid and anthraquinone.

本课题首先选取治疗下肢静脉炎相关的药效学指标，建立动物模型，在药理学实验的基础上，确立大孔树脂60％乙醇洗脱部位为有效部位，继而对该部位进行进一步的化学研究，分离出单体化合物15个，鉴定结构13个，其中有6个是从蓬子菜中首次分离得到，有2个化合物是国内外文献中未见报道的化合物，结构鉴定工作正在进行中。

We observed that the probationary teacher has very strong motives in learning to teach. However, his intention of teaching diagnostically was defeated by his relatively weak PCK and easily impacted by the traditional instruction approach at the beginning stage of his probation. His social identity within the community of practice is heteronomous. He was not able to practice intentionally at this early stage.

研究发现，这位实习教师有强烈的内发学习动机，但是实习刚开始时，由於他缺少诊断教学实作经验，教学知能尚不足，想要引起师生互动的教学容易受到挫折，容易受到辅导老师和学生对他的教学感受的影响，导致无法有效提升他的教学知能。

讨论］采用仰卧位C形臂引导下经皮骶髂螺钉固定治疗骨盆后环损伤具有安全、有效及创伤小等优点。

In theory, this kind of interferometer can divide the parasitic interferential signal, meanwhile, it has nonlinear error.

在计算过程中，对时域采样数值进行加权，然后采用多步移相算法进行位相计算，可以有效地抑制谐波误差的影响。

The acyl derivatives all exhibited higher inhibitory effect than prinsepiol, among which isobutyryl and diacetate derivatives exhibited highest activity with EC50 of 3.85 mg/L and 5.60 mg/L respectively.

在Prinsepiol 4，4'位引入不同酰基后化合物的抑菌活性均有不同程度提高，其中4，4'-二异丁酰基衍生物和4，4'-二乙酰基衍生物的抑菌活性均较好，有效中浓度(EC50)分别为3.85和5.60 mg/L，是Prinsepiol的6~8倍。

To develop standard WNV diagnostic tools, four monoclonal antibodies against WNV envelope protein domain III were produced. The isotype, the reactivity with denatured and native antigens, the affinity and specificity of antibodies have been characterized. Two MAbs (4B3 and 2F5) were used to establish an antigen capture-ELISA detection system.

为了建立有效的WNV检测方法，本研究制备了四株抗WNV囊膜蛋白第三结构域的单克隆抗体，鉴定了抗体的亚型、抗体和变性及非变性抗原结合的强度、抗原和抗体结合的亲和力常数，进行了免疫荧光分析、测定了抗原表位竞争、抗体的中和能力等，并检测了上述单抗与日本乙型脑炎病毒的交叉反应情况。
