重心低的

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 lower center of gravity makes for better balance as well.

较低的重心使得更好的平衡，以及。

First and foremost, the center of gravity needs to be kept as low as possible.

首先并且是首要的，重心要保持在尽可能低的位置。

STEP 3: Slightly shift your weight on your uphill Ski and then move your lower Ski upward.

第三步：将身体的重心渐渐转至山上板，并将稍低的雪板向上移动。

The compact, horizontally-mounted shock also helps to keep the machine's centre of gravity low - and largely because of the bike's low unsprung weight, the plush rear suspension action is going to be a revelation for many cruiser riders.

紧凑型，横向式的冲击，也有利于保持机器的中心，重心低-主要是因为自行车的低u nsprung重量，毛绒后悬架的行动将是一个启示，许多邮轮乘客。

The ultra low center of gravity combined with the center-mounted battery location minimizes roll and allows the car change direction like no other before it.

超低的重心结合中心安装电池位置，最大限度地减少轧辊，并让汽车改变方向一样，没有任何其他在它的前面。
