实体的

China is now the world's 4th largest economy, and we look forward to participating in this growth.

中国现在是世界上第四大经济实体，我们希望能够从她的发展中分一杯羹。

This is a priori mode of entity reduction.

这是一种实体还原论的先验模式。

This is not realistic, as the entity must watch out for the self, less the self be destroyed or placed in a position where the incarnation is abortively ended.

因为实体必须关注好自我，以避免被摧毁，或者处于化身以失败而告终的境地。

For example, 0 is absolute in entity space, 0× any number=0;0 shows its relativity in infinity space, etc, such as 0×∞=?

如，0在实体空间是绝对的，0×任何数=0；0在无限空间等可表现出相对性，如0×∞=？

It is specifically useful for those students who have difficulties in connecting abstract mathematics symbols and concrete experience.

此外虚拟教具还具有不占空间、容易复制、分享，课堂上易於整理等优点，也是传统实体教具所不及的。

The viewpoint that feature is an entity or abstractor with special meanings based on application fields was proposed.

提出特征是某一应用领域内具有特定意义的实体或抽象体。

First of all, the 3D model of the fire frequency adjuster was built.

首先，建立了执行元件及驱动元件的三维实体模型。

Apparently, Albert Einstein was very aware of this, and knew that all that had to be done to accomplish his mission was to somehow establish physical contact with Adolph Hitler.

显然，爱因斯坦非常清楚这一现象，而且知道他为完成任务所要做的就是无论如何要建立一次实体接触。

Compared with texts and graphics, the image conveys the information more vividly and affluently.

影像是利用各种观测系统以不同形式刻画客观世界而获得的视觉实体。

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。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
