After that, the aforementioned flow field in metering section of the triple-screw extruder with single-thread elements and 45mm pitch has been calculated too for the purpose of comparing the difference of flow fields between the single-thread element and three-thread element.

还以螺距45mm的单头螺纹元件为代表，计算了由单头螺纹元件构成的上述流场，分析、比较螺纹头数对流场的不同影响。

The practical measuring of incomplete inner thread ,using the screw gauge and the special fixture is introduced in this article.

结合生产实例介绍了一种利用定制螺纹通止规和夹具测量不完整内螺纹的方法，并讨论了相关结构的加工精度对测量结果的影响，此方法解决了常规测量法无法用于不完整内螺纹检测的问题。

This research job analysised the extending roll pass system the finish roll pass system and the ultimate roll groove. The mathematical models and experience formulations used for roll pass design are corrected according to the basic theory and the practical experience of the engineerings. The thread steel bar CARD was set up with the visual program tool-VisualBasic6.0, based on the method of the structural program design.

本课题通过对螺纹钢延伸孔型系统、精轧孔型系统及成品孔型的构成和设计方法的分析，结合螺纹钢孔型系统的基本设计理论和工程技术人员的实际生产经验，对以往孔型设计过程中所使用的数学模型、经验公式等进行了修正，以结构化程序设计方法为基础，采用可视化编程工具VisualBasic6.0建立了螺纹钢计算机辅助孔型设计系统。

The modular machine tool is used to tap 18 screw holes of M8 and M10 on the left, 15 screw holes of M8, M10, M12 on the right and three screw holes of Z1/4, a screw holes of G3/8 on the back surface. The modular machine tool uses the horizontal-type single location three-side processing plan, the processing and assembly technology capability is good, and it clamps conveniently.

同时采用机械滑台，一次装夹，对左面15个M8-7H深14和3个M10-7H深15的螺纹孔，右面7个M8-7H深14，3个M10-7H深15，5个M12-7H深20的螺纹孔以及后面3个Z1/4&-5H深20和1个G3/8&-5H深20的螺纹孔同时进行加工，不仅保证了孔的加工精度，而且还大大地提高了加工效率。
