To enlarge the service and influence of the Chinese scientific Papers to theresearchers and other users of the English.1anguage world and promote theinternational exchange between Chinese and foreign scientists，the English-language Proceedings（the Proceedings of the China Association for Science and Technology）has been inaugurated in series since 2004.Collected in this volume are 8 1 English Papers selected from the 11th Annual Conference of the China Association for Science and Technology held in Chongqing，China，September 7-10，2009，and theChinese joumals which are sponsored by the 170 member societies（their names arelisted in the back of this Proceedings）of the China Association for Science andTechnology. The Annual Conference of the China Association for Science and Technologyhas entered its eleventh one since 1 999.It is gratifying that the eleven annualcon ferences have won the high recognition of the Chinese government and thescholars from home and abroad.The Conferences provide a forum for the openexchange of information and ideas in the fields of science and technology. The papers cover the following aspects：Agricultural Science，Chemistry andChemical Engineering，Biology，Environmental Science and Technology，Medicineand Pharmacology，Safety Science and Technology，Mechanics，Forestry，Traffic Engineering，Physics，and Miscellaneous. It is sincerely hoped that，as a consequence of this conference，the academicex change between specialists and scholars would be continued and strengthened. In addition，we greatly appreciate the authors for providing the excellent papersde scribing their latest achievements in their researches.

Stream conductor insulator will be aging of difierent degrees after running for some time，since it can beaffected by the surroundings.This situation is much common in the old streets ofthe towns and the old companies.In recent years，the number offire caused by mat is increasing. In recent years，researches on stream conductor insulator are more and more popular at home and abroad.Their results are continuously applied in the production of electric wires and in the process of using electric wires.Now，foreign research institutions invented a new way to test insulation，which named restored voltage method，aiming at the defects of testing inconvenience，inaccuracy and bad effects from electromagnetic field.In China，SU Zhanpai and LI Changming from cable material research center in Harbin University of Science andTechnology studied the effects of producing heat on the extrusion swelling ratio and the effects of the ratio on tileinsulation.focusing on the extrusion swelling.What’s more，they discovered several ways of reducing the extrusion swelling ratio to improve the capability of insulation of wires and cables.
