Develop throttle using in wellbore and compound equipment on ground and constitute technique guide line on the base of theoretic research. Applying test had been carry out in 12 wells of Chuanyu gas field and 5 wells of Changqing gas field. The test results prove that throttle in wellbore have the advantages of reasonable design, easy installation and fishing. So we can get the conclusion that throttling in wellborn has great applying foreground.

Those biodegradable materials finally form into CO2 and H2O via culture of tricarboxylic acid cycle, which can be excreted from lung, kidney, and skin. Hydroxyacetic acid is a metabolic product of amino acids. Therefore, velocity of bioldegradable materials can be controlled in vivo. The recent contraception focuses on discover a sustained release system of biodegradable materials.

生物可降解材料包括聚乳酸、聚ε-己内酯、乳酸-羟基乙酸共聚物等，这些材料有很好的生物相容性，植入体内后可经生物降解成乳酸单体，经三羧酸循环后最终成为CO2和H2O，经肺、肾、皮肤排泄，羟基乙酸也是机体氨基酸代谢产物，而且生物可将解材料在体内降解速度是可控的，用生物降解聚合物作为药物载体的缓释避孕系统是目前材料学以及避孕节育研究的一大重点。

Since long, because of different requirements when working ,belt running leanly in movement ,the carrying idler's short service life, on-site maintenance big work load and so on many breakdown reasons and crucial understanding insufficiency, have made the carrying idler's function research and manufacture not be broken through, These make the carrying idlers to transport the material in inexpensive economic cost expense not to be able to obtain manifests fully, which is one that hasn't good solution of comprehensive technical difficult problem.

长期以来，由于对皮带托滚在输送机上所处不同工况性能要求，运行中存在皮带易跑偏，易损坏，托滚使用寿命短，现场维护工作量大等诸多故障原因及关键性认识不足，因而造成了对皮带托辊的功能研究和制造无重大技术突破，使皮带输送物料的最佳效果的低廉的经济成本费用未能得到充分体现，是一项没有得到较好解决的综合性技术难题。
