It is an important research subject how to control the azimuth of borehole trajectory by an application of the regularity of drift.

在井眼轨道的描述模型、设计方法和设计结果等方面，它与常规的二维剖面设计存在着显著的差异。

Changed the chip shot to make it more challenging and also to improve the feel of it--more backspin, better trajectory.

改变了切杆，使其更具挑战性，并提高它的感觉-更多的下旋，更好的轨迹。

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。

On the basis of the analyzing the whole launching process, the mathematics model of the inner ballistic is deduced. Computer procedure is complied through Visual C++ development tools, which simulate the launching process and obtain the main performance curve of inner ballistic trajectory. Mathematics model is also modified through the experimentation data. At the same time, the experiment has proved that the new launching technique has the capability of raising the muzzle velocity.
