Based on the model calculation,an FAPP ventilation system was madein Beijing Poultry Breeding Company.Through running test and a series ofphysical and chemical characteristic measurement,the distribution of flowspeed in length,and breadth was given.The average temperatureand rel-ative humidity,the amplitude of T and RH per day of 30 days in winter,and instantaneous T and RH in 24 hours wre measured in FAPP house,com-paring house and outside,the result shew that FAPP ventilation system wassuperior to comparing house.The dust concentration and microrganism con-tent were also measured in the rearing piriod of poultry,the value in FAPPhouse was junior to comparing house.

在模拟结果的基础上，设计了一套FAPP通风系统并在北京市种禽公司原种后备场种雏舍进行了实际运行试验和一系列的理化特性参数的测试，试验给出的正压管道式送风舍纵轴方向及横截面上气流速度的分布规律与模拟结果相吻合；通过对FAPP舍、对照舍及舍外冬季30天的逐日平均温湿度、温湿度振幅以及24小时瞬时温湿度的测试分析，显示了FAPP通风系统在冬季通风中明显优于负压通风系统；在雏鸡全周期的饲养过程中还对舍内粉尘与微生物的含量进行了测试，FAPP舍的值明显低于对照舍，这一结果为FAPP通风系统的推广应用提供了实验依据。

By analyzing and comparing the above test results, the special demands for welding current and time and pressure in the spot welding of zinc-coated steels were put forward.

为了在需点焊加工的产品上推广使用镀锌钢板，并保证其焊接质量，本文对普通冷轧钢板、电镀锌钢板和两种不同锌层厚度的热镀锌钢板进行了一系列点焊工艺及力学性能试验，并通过对试验结果的数据处理和理论分析，找出了几种材料点焊工艺性能上的差异，得出了一套合适的点焊焊接规范范围。

The main work of this paper: Firstly, Basing on the summarization and analysis of the walking mechanism, Parallel drive five-bar mechanism is applied for walking mechanism. And then the characteristic of the trail and positive kinematics as well as reverse kinematics are discussed. Secondly, the model of walking mechanism is established according to Parallel drive five-bar mechanism, and then a figure planning is designed for the foot-end trail. The characteristics of the parallel drive are emphasized to research in this paragraph by the method of insert value. At last, the simulation is performed in the ADAMS to compare the real result to the theoretical value. Thirdly, a sealed structure of a Quadruped Walking Robot is designed and established. The whole control system, including motor, sensor and control circuit, is sealed in the robot. Walking is derived in the way of the shaft driving and the dynamic torque sensor is used to the surrounding conditions of the robot's foot-end to be the foundation of the robot's control. At last, the applying principle of the dynamic torque sensor is researched in detail basing on the traditional sensor of the walking robot. Moreover, the principle is divided into several sorts to discuss. Finally, simulation and verification of the monitor principle are come through in the Mechanism of the Pro/Engineer.

论文的主要工作有：在对传统步行机构总结分析的基础上，提出将平面并联五杆机构应用于四足步行机器人的腿部结构，并对其轨迹特性、正运动学、逆运动学特性做了详细计算分析；依据平面并联五杆机构的模型，建立机器人步行机构的实体模型，对其足端的轨迹做了图谱规划，并利用插值法对并联驱动端的特性曲线作了研究，并在ADAMS中进行仿真，将结果与理论值相比较；然后设计了一套四足步行机器人密封装配结构设计方案，建立四足步行机器人单足结构、驱动以及传感器监测的三维实体模型，将机器人的整个控制系统，密封装配在步行机器人的机体中，通过轴传动来驱动步行机构实现步行，采用动态扭矩传感器监测步行机构的驱动关节受到的扭矩变化，从而获得四足步行机器人足端的周围情况，为步行机器人的控制方案奠定了基础；论文的最后在分析步行机器人传统控制传感器的基础上，详细分析了动态扭矩传感器的监测原理，并分几种情况分别分析了其监测原理，并在Pro/E的Mechanism模块中实现了监测原理的仿真与验证，最后给出了传感器监测信息与系统判断之间的关系。
