The results were as follows.(1) In the backward handspring, the trajectory of CM and horizontal velocity of CM in junior-high and college gymnasts were lower and higher than those of senior-high gymnast, so the vertical velocity is better when they perform tucked backward somersault. College gymnast has higher vertical velocity than junior-high and senior-high gymnasts in take-off moment of backward handspring phase.(2) Senior-high and college gymnasts have more elbow and shoulder angle in take-off moment of backward handspring and tucked backward somersault phase. Therefore, angle of both arm is bigger for performing in hand push away phase in the backward handspring, and increased the reaction force with body in the tucked backward handspring.(3) College gymnast has large knee flexions in hand support and push away moment in the backward handspring, it would increase rotation radius and better moments of inertia in the backward handspring.

结果显示：在后手翻阶段中，较低的重心轨迹和较高的水平速，有於后续空翻的垂直速；大专选手在后手翻阶段起跳瞬间有较高的垂直速；高中及大专选手在后手翻起跳脚地瞬间和团身后空翻起跳脚地瞬间时，肘、肩关节角皆大於国中选手，使其在后手翻起跳地瞬间时，双臂的伸展於后手翻的手推地面的动作，而团身后空翻起跳脚地时，双臂向上摆於身体向上伸展方向的掌握，并使重心有一定的腾空高；大专选手在后手翻阶段的手著地瞬间和手地瞬间的膝关节角较大於高中和国中选手，使其可增加身体的旋转半径，并能获得较佳的下摆动能，而膝关节角小则形成屈膝的动作，导致重心水平速低，减少下摆动能和影响整体动作的节奏和韵。

Angle base side flat, two angle outward show, again, after bend.

Two different methods based on ship rectangular frame and inertial frame are proposed separately according to consistence of radar base angle and beam angle.

本文首先研究了舰载两轴雷达系统抑制船摇的方案，对雷达天线转角和波束转角一致和不一致的情况，分别提出了基于甲板坐标系稳定和基于大地坐标系稳定的不同方法。

Base on intermission angle principle, a practical method was established, which avoids the disadvantage of the traditional method with accurate measurement of intermission angle, but only analyses the wave transformed from original signal after transform.

因此在对比基于小波理论与其它理论的保护算法的基础上，本文对基于小波理论的保护的实际应用作了进一步的研究。

The composite article as recited in claim 6 wherein each core is substantially triangular in cross section and each U-shaped channel is contoured such that one side forms an acute angle with the base and the other side forms an obtuse angle with the base.

综合文章作为背诵在索赔6 ，其中每个核心是大幅三角在截面和每一个U形渠道是轮廓，例如一方形式一锐角与基地和另一边的形式一钝角与基地。

ABSTRACT With the development of installed capacity and power system interconnect scale, the importance of stable monitor and control is becoming more and more obvious. The phase angle is one of basic state variable of electric power system, so monitoring and controlling power angle and phasor of the bus voltage are the most important means.

随着电网装机容量的增大及电网互连规模的扩大，电网的稳定监视和控制越来越重要，而相角是反映系统最基本的状态变量之一，因此监视和控制发电机的功角和母线电压相量，将是电力系统稳定监视和控制最重要的手段。

Assuming that the friction angle on different slip planes varied with the angle between the slip plane and bedding plane, an anisotropic strength criterion was established based on the concept of SMP. The formulation for cross-anisotropic granular materials was then derived.

基于SMP准则，假定不同平面上的摩擦角随该平面与沉积面之间的夹角变化，提出了一般应力条件下各向异性粒状材料的强度准则，称为ASMP准则，给出了该强度准则在横观各向同性条件下的表达式。

The theoretical analysis and optimizing design were implemented to the structuralparameters of major working components, such as the clearance between cutter heads, thearrange of bent blade, grass removing angle and setting angle.

本文通过上述的试验和分析，给出了刀盘间距、机器前进速度以及刀滚旋转速度这三个因素在满足作业要求(覆盖率、埋草深度、碎土率)的前提下，降低功耗的最优组合方案，为进一步进行整机参数优化设计提供了重要的理论依据。

Considering the factors such as randomness of natural lightning locus and the coexistence of primary and secondary leaders, it is necessary to lead in the concept of dynamic lightning protection shielding angle. It is suggested that the angular bisector of practical protective angle formed by ground wire or earth pin in UHVAC transmission line and conductor should be aligned with the direction of lightning leader as well as the ratio of vertical span to horizontal span and the impact of wind speed should be considered.

考虑自然闪电轨迹的随机性和雷电主先导与次先导并存现象等因素，有必要引入动态防雷保护角概念，建议特高压交流线路中地线对导线的实际保护角形成的角平分线应与雷电先导的来向一致，并应计及垂直档距和水平档距的比值和风速的影响。
