Raise the tackle above ground for about 500mm using man power, until it goes to OA, start elevator; pull the tackle with low speed to OB (inclination angle=45 degree), and then use man power to lift the front legs slowly, put them into the two holes in the beam.

用人力将滑车抬起离地面约500mm高度达到OA位置，启动升降机；低速缓慢拉起滑车部位及至OB位置（倾角45度）时，再用人力将前支腿缓慢撑起，置于横梁两端的孔中，前后支腿用侧连杆连接好。

The stude announces that their changeable regular of the center of gravity level speed in supporting phase is falling in tne first cushioning phase. When their center of gravity's vertical lines pass their heels and their knee joints go on extended contraction ,their center of gravity level speed has extended .the reason is that their angles have passed the heels and their swinging legs' kenn joints have swinging the front of their bodies. Its power originates the swinging leg's forward active swinging and the decurtation contraction of hip joints 、ankles of the supporting legs.the swinging leg shows "the calf's active backward swinging"before its landing impact,the skill affects the loss of center of gravity level speed when the swinging leg lands.they enlarge their trunks' forward-landing impact phase ,it can decrease the center of gravity level speed's loss after landing and impel the center of gravity level speed to pass the supporting spot quickly.

两人缓冲阶段身体重心水平速度变化规律是在体前缓冲阶段呈下降趋势；当身体重心垂线超过脚后跟后，在膝关节继续缓冲做退让收缩的情况下身体重心水平速度开始加大，原因是踝关节在最大缓冲时身体重心已移过支撑面及摆动腿膝关节已做体前摆动，主要动力来源于摆动腿的积极前摆和支撑腿髋、踝关节的克制性收缩；在摆动腿下压着地前期是大腿积极下压小腿随大腿的积极下压顺势向前下滑摆，在摆动腿下压着地后期表现出"小腿积极回摆"技术，对减小着地时的水平速度损失、加大向前用力都有积极影响；适当加大摆动下压着地阶段躯干的前倾角度，有利于减少着地时相的速度损失和有利于身体重心较快的移过支撑点；缩小后蹬结束后的后伸动作幅度，有利于减小腾空时间。

20X50y on :50, odds 15m kick underwater, then swim through turn and entire second 25 under on the way back; evens 25 kick under surface, one stroke away from wall turn and hold 15m kick underwater off turn.

前25码，出发时做一个水下15米小幅度蝶泳腿的滑行，然后游完剩下的十米，转身后一口气踢水下25码；再完成25米的回程匀速蝶泳腿后，在距壁一划远的地方开始转身，然后接一次水下15码的小幅度蝶泳腿滑行。

The simple forward extensions– such as Adho MukhaVirasana, Adho Mukha Svastikasana, Janu Sirsasana, TriangMukhaikapada in Paschimottatanasana, Ardha Baddha Padma inPaschimottanasana, Marichyasana, Parsva Upavisthakonasana, AdhoMukha Upavisthakonasana done restfully checks the over bleeding,soothes the abdomen and makes the throbbing brain-cells rest.

和缓地练习简单的前屈动作-如下犬式， AdhoMukha Svastikasana，单腿背部伸式，单腿跪伸展式，半莲花单腿背部伸展式，圣哲玛里琪式，屈肘支撑的和上半身完全伸展的坐角式可以缓解流量过大，缓和下腹部不适及安抚大脑细胞。

We evaluated the sufferer's clinical curative effect before the second treatment, third treatment and in the 21th day with evaluate criteria.painful degree was recorded respectively with the visual analog score and lumbodynia and skelalgia score before each time of treatment and 7st day after the last treatment;detected IgG and IgM from blood serum before the first treatment and 7st day after the last treatmen.

依据临床疗效判定标准，分别在第2次治疗前、第3次治疗前和第21天评价患者的临床疗效；应用腰腿痛评分量表和VAS疼痛评分量表分别在每次治疗前和最后一次治疗后第7天对患者进行疼痛评分；并于第一次治疗前和最后一次治疗后第7天分别检测患者血清中IgG、IgM的含量。

To prevent the interference in the antenna all-round rotation plane the nose landing gear legs are retracted rearward into the cowlings flight-wise and the main legs are retracted upward.

为防止在天线干扰全面旋转飞机前起落架腿缩回到整流罩飞行明智的，主要是收回腿向后向上。

Compared with the sail style and the hang style, the hitch kick style have advantages to join the front swing and trig swing of swing leg tightly, to speed the buffer and stretch of take-o?leg, to acquire more vertical muzzle velocity and to decrease losing of horizontal velocity, which results in more velocity and more angle when take o?.and more vertical height of body center, has advantage to obtain better result.

走步式空中技术能在起跳过程中通过紧密衔接的摆动腿加速前摆和制动前摆，加快起跳腿的缓冲和蹬伸动作速度，促进身体重心获得更大的垂直速度，而且水平速度没有更多的损耗，从而获得更大的腾起速度和腾起角，腾起时身体重心的垂直位置更高，最终取得优异成绩，促进跳远起跳技术朝着快速积极的方向发展。

The main technical parameters which decide the movement speed are the ankle angle of the support leg, the horizontal velocity, the hip angle and the support leg's hip joint angle, knee angle and the former support distance at the moment of contact, and the latter leg's hip joint angle, the upper arm's movement scope, the support leg's knee angle, the swing knee's angle, the support leg's hip angle at landing phase, and the ankle angle, the support leg's hip angle, the swing velocity of the former leg, the hip angle of the swing leg and the angle of the landing knee at the pushing phase.

我国优秀男子百米途中跑着地瞬间对动作速度起主要贡献的技术指标是：支撑腿的踝关节角、着地瞬间脚的水平速度、大腿夹角及支撑腿的髋角、膝角和前支撑距离；垂直缓冲瞬间是摆动腿髋关节角、上臂前摆幅度、支撑腿和摆动腿膝关节角、支撑腿髋关节角；后蹬瞬间是踝关节角、支撑腿髋关节角、大腿前摆角速度、摆动腿的髋角及支撑腿膝角。

These 25 are separated by 25 meter kick, it is important in streamline drill that you can also consider an alternative kicking position in between each segment of streamline +2, streamline +4 and streamline to the full stroke alternating with 25 torpedo kick on your back then 25 with torpedo kick on your front, 25 with arms folded kick front and back, and 25 overlapping arms kicking, both on you front, side, or back.

在这些25练习之间穿插着进行25米打腿。流线型练习中需要留意的是，你可以在每个流线型+2、流线型+4和全划臂流线型练习中间穿插的打腿中考虑采用交替的姿势– 25米仰卧鱼雷打腿、然后25米俯卧鱼雷打腿、25米手放两侧仰卧和俯卧的打腿、以及手前交叉的俯卧、侧卧和仰卧打腿。
