扩展

Extension modules are shared betweeninterpreters as follows: the first time a particular extension is imported, it is initialized normally, and a copy of its module's dictionary is squirreled away.

扩展模块在自解析器之间是被共享的，如下：一个特定的扩展被第一次导入后，他被正常的初始化，并且把一个它的Module的词典的浅拷贝保存到一边去。

Then based on the three traditional elements, we superadded management, information and technology to extended the elements of traditional agricultural to six in all.

Furthermore, the extensive development in globe trade of animal and animal products increased the risk of prevalence of animal diseases and zoonoses. Facing these challenges in a changing environment, Official Veterinary Services must accomplish the historical mission.

加之兽医工作由传统的动物疾病诊疗逐步扩展到食品安全、动物福利和环境保护范围的扩展也使各国兽医机构面临前所未有的挑战，如何提高国家动物疫病防控能力，促进动物福利和食品安全成为日前世界各国增强兽医机构能力建设的关键性问题。

The object of the present paper was to study the relationship between corrosion fatigue crack growth rate da/dN and stress intensity factor amplitude ΔK of 07MnNiCrMoVDR steel by corrosion fatigue crack growth rate experiment in H2S solution. This steel is the typical material used in chemistry and oil chemistry equipment in our country. Corrosion fatigue safety assessment method of pressure vessels with defects in service could be explored and investigated.
