The most important are as follows: Detection of type: valve stem seal leakage test and test; water valve tightness test; switch tightness test; the take-off safety valve Test; Detection Object: valve, the cut-off valve , safety valve, throttle valve, check valve, swing check valve, ball valve, regulating valve and other hollow pump body, valve body and housing, etc.; way valve connection: flange connection, threaded connection, welding connection; detection medium.

最重要的有以下几种：检测类型：阀门密封性试验及阀杆泄漏性试验；水中阀体密封性试验；开关密封性试验；安全阀的起跳值试验；检测对象：闸阀、截止阀、安全阀、节流阀、止回阀、摆动式逆止阀、球阀、调节阀和其他中空的泵体、阀体和壳体等；阀门联接方式：法兰联接、螺纹连接、焊接联接；检测介质。

When surface of TiO2 powder is enveloped by carbon, the reduction is mainly solid-solid reaction between carbon and titanic oxide.

结果表明钛氧化物的还原是逐级进行的，反应过程伴随着相变，当TiO2粉末和C粉末均匀混合时还原碳化反应主要依赖于CO／CO2传质的气固反应，当TiO2颗粒表面被C包膜时主要是碳和钛氧化物之间的固固反应，当TiO2粉末和C粉末混合压球时则两种反应机理均有。

A program——VRMLMaker has been developed for the 3D chemical structure display on the Internet in our chinese drug database retrieval system. VRMLMaker can convert a molecular MOL2 or ML2 format file to VRML format files in four different styles:wire-frame, capped sticks, ball-and-stick, and a CPK space-filling model. VRMLMaker is developed based upon molecular model and virtual reality modeling languagetechniques. The working procedures of VRMLMaker are described.

何敏在开发基于Internet的中药信息检索系统时，为了解决三维(3D)化学结构在Internet上的传输和显示问题，利用分子模型和描述3D世界的虚拟现实模型语言等技术开发了一个可以把化学的MOL2或ML2格式文件转换为球棍型、空间充满型、线型、棍型等4种虚拟现实模型语言格式文件的软件。
