At first in the preliminary design this paper computes the linear damping coefficient of the viscous damper employed in this project using Composite Response Spectra approach, meantime, this paper proves that reducing the exponent of velocity of the piston can increase the magnitude of the dissipative energy, because of the viscous damper employed in the practical project character nonlinear behavior; next this chapter performs analysis and comparison between the building without and with the viscous dampers aforementioned when the building suffers from various Time Domain Response, from the angle of displacement, interstroy drift, velocity, interstory velocity, acceleration, energy, maximum axial force of the dampers and of the column etc., in order to prove that the incorporating the viscous dampers into the buildings has great superiority on enhancing its aseismic performance ; furthermore, this chapter also expatiates on diverse assembly form of the viscous dampers that results in the adverse impact on the internal force of the structural member in this building, on the ground of which this segment bring about the preference of the assembly form of the viscous damper; finally this chapter points out the sphere of application of the analysis and computation using Composite Response Spectra approach in design: it is available in well-proportioned stiffness structures and isn抰 available in the structures that contain weak story. It is recommendable, particularly, to incorporate the fluid viscous dampers into this structure that contain weak story to refrain earthquake and reinforce, such as the Central Hall of Shanghai Exhibition Hall.
首先使用了反应谱分析法设计出欲附设的粘滞阻尼器的线性阻尼系数,由于实际工程所用的粘滞阻尼器具有非线性的特性,故而笔者又证明了降低速度指数对提高粘滞阻尼器的耗能量的优势所在;接着分别从位移、层间位移、速度、层间速度、加速度、能量、最大阻尼出力和柱轴力等不同的角度对结构在附设粘滞阻尼器前后的时程反应进行了分析对比,籍此在实际工程中证明了附设粘滞阻尼器对于提高结构的抗震性能的优越性;再者,笔者还阐述了采用不同的粘滞阻尼器布置方式对结构中构件内力特别是柱轴力和基座竖向反力产生的不利影响,并在此基础上提出了布置方式的优选;最后,指出了反应谱法在设计中的适用范围:对于均匀结构反应谱法能够使用,而对于含有薄弱层的结构反应谱法并不适用;对于类似于上海展览馆中央大厅的含薄弱层的结构尤其值得使用粘滞阻尼器的方法进行抗震加固。

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.
本实验分两部分:第一部分、对转化番茄的形态及细胞显微结构进行观察与分析,实验表明转化番茄形态与对照相比有明显的变化,其叶面积变小,叶形收拢,这种结构可有效地减少水分的蒸发,缓解由盐胁产生的生理干旱;组织解剖结构结果显示,耐盐番茄在细胞结构上发生了明显的变异:其气孔器倾向下陷,表皮毛增多,叶脉微管组织不发达,微管束周围出现增多的贮水细胞,叶缘及其它部位表面分化出大型的多细胞分泌型结构,这些结构与转化番茄后代较强的耐盐能力有关。

This paper discusses the dynamical characters of the RC mega-sub controlled structure. It is concluded that the deformation and the acceleration of vibration-absorption megaframe structure can be well reduced under the windward pulsoting wind load, through choosing the reasonable the member parameter and the accessional columns stiffness of the structure. So the safety of the structure is enhanced, and the comfortable need is satisfied. So the new mega-sub controlled structure is a kind of ideal super tall building structure configuration, it will have the bright future.
