Statistical relationships between the initial wear and uniform wear periods are obtained. The results show that there is qualitative relationship between wear rate during initial wear period （WRIWP） and wear rate in uniform wear period （WRUWP） to certain extent. On this basis,a tool material rapid selection method based on the initial wear is put forward,and suitable tool materials for machining titanium alloy are selected. The experimental results indicate that this method is effective and useful. The new tool materials rapid selection can be used to select suitable cutting tool materials quickly before carrying out systematic machinability tests with the most suitable tool materials. The technology can be applied to doing the initial selection of cutting tool materials in either the machinability research or the workshop production.展开更多

[ Method] By screening enriched bacteria, solid medium and medicine and comparing effects of rapidly choosing medicine, a kit that could pick up the right medicine quickly for mariculture bacteriosis was created. [Result] The pilot test in some regions showed the kit had ideal yesalts and was easy to operate. [ Conclusion] The kit, a convenient and useful kit to detect drug sensitivity, can help users select effective drugs from many common medicines rapidly and accurately, and it is mainly suitable to use in the rapid selection of an appropriate medicine for maricultural bacteriosis.展开更多
