On the basis of investigating the sound field of a plane piston transducer and the relations between sound field and radiation force, by settling four plane piston transducers driven at the same frequency at each corner of a regular triangular pyramid with their sound-beam axes crossing at the center of the pyramid, this technique uses ultrasonic wave synthetic theory to acquire a three-dimensional ultrasonic standing wave field. The micro-component can be captured, transported, released in the range of space by adjusting the phase of the transducers.

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。

Thirdly , a conclusion has been settled down in this dissertation: Because the shaft inertial force vector do not pass the center of the rotating center of the system, there is a moment generated by the shaft inertial force and the counterforce of the cylinder wall to counterbalance the pressure which is imposed by the piston, so, it is important to consider the tortile effect on the flexible supporting component of the balancing machine dedicated to motorcycle crank set, which is originated by the moment.

第三：得到了一个结论：在设计制作曲柄连杆机构动平衡测试装置时，必须考虑这一受力情况，即连杆在作平面运动时，其自身的惯性力与汽缸对活塞的反作用力二者之间形成的力偶将会对弹性支承元件产生扭矩的作用。

The small end of connecting rod acts to-and-fro movement, and the big end of acts circumvolve movement. The connecting rod body acts complex plane movement.
