The SSTA of February and August in 1998 had two peaks, while the wind speed reached its maximum minus anomalies in January and August. In order to find the circulation anomaly in the South China Sea, the circulation of 19952000 had been calculated by the ECOM hydrodynamic numerical model. The elevation and circulation of January and August in 1998 indicated that there were great anomaly of elevation and circulation after this El Nio event.(1)In January, the whole South China Sea had positive sea level anomaly and anticyclonic velocity anomaly, so the cyclonic circulation was weaker than normal.(2) In August, the South China Sea had positive sea level anomaly, especially stronger in the east of Vietnam, and cyclonic velocity anomaly in south, anticyclonic velocity in north, especially strong in the east of Vietnam. So the cyclonic gyre in the north and the anticyclonic gyre in the south were both weaker than normal, and an anticyclonic gyre appeared in the east of Vietnam.

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。

The paper is based on the practical application of certain armed helicopter's barbette tracking system, which has discussed the model of AC servo system, the testing and modeling of certain micro-machined velocity gyro.
