The combined control consisting of the engine torque control and driving wheel brake control was adopted for the antislip control during driving,while the brake control based on threshold was adopted for the antiskid control during braking.

驱动防滑采用发动机力矩和驱动轮制动的联合控制方式，制动防滑采用基于门限值的制动控制方式。

This thesis in term of characteristics hereinbefore, adopted slippage and differentia rotate speed theory of electromagnetism to imitate differently road conditions of appendiculate quotiety.

并以此为基础，进一步分析了车轮在滚筒上被拖动时、制动时和急加速时的受力情况，建立了附着力与电磁滑差离合器输出力矩之间的力学模型。

To observe and measure the distance and angulation of some muscles such as flexor carpi ulnaris,extensor carpi ulnaris , flexor carpi radialis,extensor carpi radialis longus,extensor carpi radialis brevis, brachioradialis,etc,we achieved the moment of force and loaded them in the model .

测量8具新鲜成人尸体的前臂主要肌肉和韧带横截面积，分别取其平均值，通过横截面积的肌力计算法，求得肌力和韧带力。主要肌肉为肱桡肌、桡侧腕长伸肌、桡侧腕短伸肌、尺侧腕伸肌、尺侧腕屈肌、桡侧腕屈肌等。测量的主要韧带为腕掌侧韧带、腕背侧韧带等。测量主要肌肉和韧带与坐标轴的夹角，求得分力值，然后直接或根据力矩等价原则间接地将肌力加载于模型体表各节点。

Second, this dissertation develops the qualitative and quantitative analysis methods for cogging torque.

其次，本文发展了齿槽力矩的定性和定量分析方法。

The fundamental ways for reducing the dispersed cogging torque are also given.

Methods. Four groups of thoracic segments with different PS constructs were loaded to failure with a rotational torque applied to the construct to simulate the left to right derotational force applied to a typical idiopathic dextrorotary thoracic scoliosis curve.

模拟对典型特发胸椎右弯从左至右的去旋转操作，对4组胸椎标本使用不同的PS连接方式，施加旋转力矩负荷至失败为止。

Moreover we formulize the optimal path according to the theory of B-spline Curve, so the path which is composed by the grid point can transform into a continuous and smooth curve. By formulizing path we can also calculate angular velocity, angle acceleration, and torque in dynamics.

另外我们根据B-spline Curve的理论将最佳路径参数化，使由格点所组成的最佳路径转换为一条连续且平滑的曲线，藉此我们也可以计算动力学中的瞬间角速度、角加速度与力矩。

At the same time,apply akind of trail controller using self-adapted controller to induce the effect arisen by the torque vibration because of load,frication and so on.

同时，应用了一种基于自适应控制器的跟踪控制结构，以解决由于负载、摩擦等因素的变化带来的力矩波动对加工精度的不利影响。
