In China, there is no research in the field previously. This thesis supported by the Ministry Advanced Research Foundation of China, make a basic study of the instrument. Its achievements read as follows:(1) A new analytic method based on the concept of an equivalent volume force presented in this thesis, which solve the problem of piezoelectric beam, is simple, clear and reliable. By means of it, the design parameters for QRS have been calculated and analyzed serially, i. e., optimum electrode configurations are chosen, the side ratio of beam is determined, and the formula of electrode location efficiency is derived.

在我国这方面的研究尚属空白，本文在兵器部预研基金项目的支持下，对这种器件进行了基础性研究，从而填补了国内空白，具体包括如下内容：(1)提出了等效体力概念，以此为基础建立了一种分析压电振梁问题的新方法——等效体力分析法，该方法物理图象清晰、计算简明、结果可靠，它可以对QRS的设计参数进行系统的理论分析。

Then through series experiment of coupling beams only add diagonal bars on the basis of traditional reinforcement with Zhanlin, we can conclude this plan for steel bar can satisfied the ductility demand of short-span coupling beams in tube body structure of Chongqing area. Through the computer simulation we can know: Procedures outputs coupling beams'ductility demand mainly in 1.5 to2.0 (maximum value 2.2), comparing the simulation of 8 or 9 degree , we can see the response of the whole structure and yielding degree are much small.

计算机分析程序输出的连梁的转角延性大多在1.5到2.0之间(最大值2.2)，对比以往本学科点对8度和9度等高烈度区的同类型结构的地震作用模拟分析可以看出，6度区大震作用下不管是结构的整体反应还是各杆件的屈服情况都比高9度和8度区小很多。

By using a shooting method, the strongly nonlinear ordinary differential equations with two-point boundary conditions were solved and numerical solutions for thermal post-buckling and bending deformation of sandwich Timoshenko beam with pinned-pinned ends and subjected to transversely non-uniform temperature rising were obtained.

The results show that the nonlinear response of steel frame in fire can be divided into four stages, the temperature distribution in beam section is nonlinear, and joint is the weak link in steel frame fire resistance.

研究结果表明，火灾下钢框架的非线性反应可以划分为4个阶段，火灾中梁的截面温度为非线性分布，节点部位是钢框架抗火的薄弱环节。

Red beam from 2,110.3 meters, the winding down of a high-level snow Road ------ Jinlong Road, the Snow Road, a total length of 1800 meters, 50 meters wide, with an average gradient of 18 degrees is ideal for giant slalom practice (Wanlong ski snow on the needs of the faithful, especially in this season free of charge twice a month to teach new rotary technology projects), but this trail has been adopted by the International Ski Federation of the acceptance can be contractors, including the World Cup, including the six individual world-class alpine skiing competitions.

从红花梁至高点2110.3米处，蜿蜒而下的一条高级雪道------金龙道，其雪道全长1800米，宽50米，平均坡度18度，非常适合大回转的练习（万龙滑雪场基于雪友们的需求，特在本雪季新增每月两次免费传授回转技术的项目），而且此雪道已通过国际滑雪联合会的验收，可承办包括世界杯在内的6个单项的高山滑雪国际级比赛。

The care-giving team then moves on, visiting 36-year-old lymphoma sufferer Liang Weiming, who has trouble paying his medical bills; volunteers also bring a soothing song to dispel the loneliness that this solitary old woman feels.

志工继续到下一户关心36岁的梁卫明，他罹患淋巴癌，高昂的医药费更是压的他喘不过来，独居的奶奶慈济人也用歌声排解她的寂寥。

After the movable support operates the box, it should pay attention to the Teflon board and the stainless steel plate protection, prevented scratches and the dirty things adheres to the surface of the stainless steel board and the tetrafluoroethylene slide board ,and pay attention to inspecting
