击球

Tungsten metal at the bottom of the design, leading-edge design of a lower technological level of different players can be hit more easily to the sweet spot, as at the same time, double ball design to ensure that the club and ball touch the grass, so as to achieve a more successful hit .

钨金属底部设计，更低的前缘设计使不同技术水平的选手都能更轻易击到甜蜜点，以此同时，双重球设计确保球杆与草的击球触感，从而达到更成功的击球。

With the methods of documentation, observe and physics statistics, the paper studies hit skills and stroke amounts of each round. And the paper tries to analysizing the change of fields of serve falling to the ground, the stroke amounts of each round, utilization ratio of each hit skill and the effect of return of service and handle skill of the third stroke in world top men's doubles nowdays after implement of new rule.

本研究采用文献资料法、观察法、数理统计法等对运动员的击球技术和各回合的拍数情况进行了研究，试图分析新规则实施后，当今世界顶尖男子双打选手的发球落地区变化情况、各回合的拍数情况、各击球技术的使用率以及接发球效果与处理第三拍技术。

Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood. If football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking of notes, chores and responses.

你用一只脚搓搓土地；用手擦擦手套上的球套；看着击球手的双眼，体会击球棒的速度，听着击打木棒时的声音，如果美式橄榄球是运动的交响乐，那棒球则是一曲室内音乐，音符在空间中交织、合声、回响。

You feel like you kind of have to live up to this and play the miracle shots, you know, the crowd-pleaser stuff,' Federer has said of his own game.

你感觉你不能辜负你的天赋，必须要打出貌似不可能的击球，就是那些能娱乐观众的击球。

By adopting the basic theory of rigid body mechanics, this paper expounds the safe striking range to avoid miscue and the qualitative and quantitative analysis of force of striking and of the cue ball motion.

运用理论力学的基本原理，确定了避免"滑杆"的安全击球范围，对台球击球和主球运动过程中的受力情况，进行了定量计算和定性分析。

Through the dynamic analysis of the kicking system,the optimal position and orientation of kicking were derived.

依据理论分析结果对旋球式带球结构和电磁式击球机构进行机构优化设计，提高带球的稳定性和击球的准确度。

In kick hitting, the moving forward velocity of bat is the highest when the ball was hit at the right moment, which the left elbow angle is almost 180 degrees and the right elbow angle is between 100-110 degrees. In the hitting process, the displacement of body in backward/forward direction and the resultant velocity with kick hitting are larger than those with glide hitting.

一、在击中球瞬间抬腿击球法左肘关节角度接近伸直与右肘关节角度介於1 00度110度时，球棒的前移速度最大；且在整个挥棒过程中前后方向身体重心位移、合速度明平均大於滑步击球法。

Rounders when batting - everyone was fielding on the other side to the direction I hit the ball!!

击球时， Rounders -人人都派出的另一边的方向我的击球！

After comparing with previously report, conclusion was as follow: when players use take-off spike movement by single-foot, the strides should increase progressively after observing the ball's direction, and raise the height of jump by getting faster horizontal and vertical velocity of body gravity. In order to avoid increasing the time of take-off, the body gravity is inadvisable to drop so much. In air motion period, player's movement of arm swing will influences the time of spike, if we emphasize the quick offensive, it should reduce the movement of arm swing to decrease the time of spike. When spiking, the joint of elbow should flex by a little range to make forearm powerful.

经由本实验结果与过去研究比较后得到以下结论：选手在执行单脚起跳扣球动作时，助跑的步幅宜在观察球的动向后，采取递增的方式助跑，并加快身体重心水平速度及垂直速度，以提高起跳高度；起跳期起跳脚踏入瞬间身体重心不宜大幅度的下降，以避免增加起跳所花费的时间，影响扣球的节奏及战术的执行；空中动作期时，选手的挥臂动作会影响击球时间，若要强调快速的进攻节奏，宜减少扣球的挥臂动作，以降低完成扣球所需的时间；而击球瞬间肘关节宜保持小幅度的弯曲，以发挥前臂的力量和速度。

He honed his putting skills by hitting balls with a soft-drink bottle wrapped in sticky tape.

同时，他用粘胶带包扎饮料瓶击球以此来提高自己的轻击球技巧。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
