The human heart is the center of the cardiovascular system. Integrated with mechanical, electrical, neural and biochemical properties, the heart is difficult to model, and there is no ideal integral model now. The developed electrical models haven't considered the mechanical properties and blood flow process in the heart; while the mechanical ones have normally deal with the heart in the diastole period, and the electrical activity was simplified too much although some mechanical models have investigated the heart during systole.

心脏是循环系统的核心，它集机、电、神经和生化控制于一体，建模难度很大，目前尚无较理想的统一模型；心脏电生理模型未与心脏的机械动力过程和血液流动过程联系起来；而心脏力学模型大都只研究舒张期的力学特性，即使研究收缩期心脏的力学问题，也往往对心电兴奋做了许多简化假设。

Through to pumps with the mechanical seal practical application and the theoretical analysis, proposed the mechanical seal actual seal effect not only with the mechanical seal own performance related, the condition which with other spare parts also which provides the condition as well as the seal servosystem provides to have the important relations, therefore pumps the unit product when the design, must for the mechanical seal use provide a good external condition.

通过对泵的机械密封实际应用和理论分析，提出了机械密封的实际密封效果不仅与机械密封本身的业绩有关的条件与其他零件也提供了条件以及印章伺服系统提供有重要关系，因此，泵的单位产品的设计时，必须对机械密封使用提供了一个良好的外部

The welding nugget happened to dynamically recrystallize and the refined crystal grains were obtained and the majority of Mg_2Si particles dissoluted due to the intensive mechanical stir and higher high temperature. In the thermal-mechanical affect zone that was heated under the recrystallized temperature, the crystal grains were elongated due to the mechanical stir and Mg_2Si particles partly dissoluted and the others grew. In the heat affect heat without the mechanical stir, to some extent, both of the crystal grains and the majority of Mg_2Si particles grew.

焊核区受到强烈机械搅拌作用和加热到较高的温度发生动态再结晶，得到细小等轴晶组织，Mg_2Si相以溶解为主；热机影响区加热温度低于再结晶温度，在机械搅拌作用下晶粒由于塑性变形而伸长，Mg_2Si相部分溶解，部分长大；热影响区仅受加热影响，晶粒有一定程度长大，Mg_2Si相以长大为主。

In order to strengthen the management on old major mechanical and electrical product, old mechanical and electrical products (see the appendix for detailed catalogue) relating to production safety, personal safety (electric appliances, medical apparatus and instruments) and environmental protection (engineering and Vehicle and ship craft machinery), as well as those quota, specially designated, or unifiedly registered (including those old mechanical and electrical equipment provided by foreign investors in foreign investment and processing trade enterprises), shall be dealt with according to the Notice on Strengthening Management on Imported Old Mechanical and Electrical Products Guo Jing Mao Ji No.

一、为加强对重点旧机电产品的管理，对涉及生产安全、人身安全和环境保护的旧机电产品及配额、特定、集中登记的旧机电产品（包括外商投资和加工贸易企业由外商无偿提供进口的旧机电产品）仍按《关于加强旧机电产品进口管理的通知》（国经贸机〔1997〕877号）办理。

The classic macroscopic mechanical models, which characterize the concrete and granite as continuums at macroscopic level and consider the test results of laboratory scale specimen as the mechanical properties of the material, could analyze the mechanical response of structures with greater size. In reality, the test results of laboratory that are generally called physical and mechanical parameters of material are average responses of a heterogeneous specimen with a certain size.

有关混凝土和花岗岩力学特性的力学模型都是基于混凝土和花岗岩材料的宏观层次研究其力学特性，其主要特点是把材料理想化为均质材料进行研究，把实验室尺度下力学试验的结果作为材料的力学参数，以此为基础进行更大尺度宏观结构的力学响应分析。
