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。

Therefore if thou shalt separate from thyself, that is, from thy understanding, whatever others do or say, and whatever thou hast done or said thyself, and whatever future things trouble thee because they may happen, and whatever in the body which envelops thee or in the breath, which is by nature associated with the body, is attached to thee independent of thy will, and whatever the external circumfluent vortex whirls round, so that the intellectual power exempt from the things of fate can live pure and free by itself, doing what is just and accepting what happens and saying the truth: if thou wilt separate, I say, from this ruling faculty the things which are attached to it by the impressions of sense, and the things of time to come and of time that is past, and wilt make thyself like Empedocles' sphere

因此，如果你是自己，也就是说使你的理智同这些事情分开－即不管别人做或说了什么，不管你自己做或说了什么，不管将来可能发生什么事情使你苦恼，不管在将你包裹的身体中，或者在天生与身体结合在一起的呼吸中，有什么东西违背你的意志而附着于你，不管那外部缠绕的事物旋涡是如何旋转，为了使免除了命运束缚的理智力自身能纯粹和自由地活动，那么去做正当的事，接受发生的事和诵出真理吧，我说，如果你使这种支配能力脱离开那些通过感官印象而附着于它的事物，脱离开那些未来的和过去的事物，你就将使自己像恩培多克勒的球体一样

On the one hand, the component method is introduced into flowchart design, which can not only enlarge the depth and the connotation of the flowchart, but also extend the traditional concepts of the flowchart. By combining the component method and the objectoriented method, it will be easy to illustrate the industry flow and meet with the future requirements of the industry control software. On the other hand, the trajectory concepts in plane moving, the method of using Bezier Curve to approach the 1/4 arc to implement the arc circumrotation, the method of using graphic elements' combination to extend the expression capability, and the method of combining the graphic elements'combination, three-dimensional graphic elements and bitmaps to realize the three-dimensional effects to express the industry flow more realistic are brought forward in this dissertation.

工控软件中最能够体现人机接口设计创造性的画面当属流程图，本文对流程图设计进行了深入研究，提出了一种工控软件流程图设计的新方法：一方面在流程图设计中引入部件化方法，扩展流程图的深度与内涵，延伸了流程图的传统概念与意义，将部件化技术与面向对象技术相结合，能够更好地实现对工艺过程的描述并适应工控软件的未来发展要求；另一方面对流程图中动画关联和三维化这些新兴领域进行了研究，提出了平移动画中的&轨道&概念，以实现图元的沿曲线平移，提出了在圆弧旋转动画中用Bezier曲线逼近〓圆弧的工程化方法，并用最小二乘法进行了验证和工程化参数的获取，实现了利用图元组合来扩展流程图的表达能力，采用了图元组合、三维图元和位图相结合的方法来实现逼真的三维效果，以使工控软件更加符合人机工学，更能形象地反映工艺流程。

The further away I hold my fingers from the nib of the pen the more flexibility I have in rotating the head of the pen to position it at different angles to the page which allows for different writing styles.

一个很具未来性的设计，我喜欢他的外观和在我手上的感觉，我发现我的拇指与食指越接近笔尖，越能控制笔触，而且旋转笔头於不同的角度可以写出不同风格的字。

In order to decrease the weight of tracking system and make suitable use of the Lander space, the pitching-axis of Lunar optical telescope is vertical with the Lander's flank, its rotation part is fastened on the Lander's flank, the azimuth-axis adopts rotation reflecting mirror, the flat mirror is located before the telescope tube, the angle of flat mirror and the telescope ray-axis is 45°,so that the reflecting ray can enter the telescope optical system, the scan of the mirror can be accomplished by the rotation of the telescope tube.

工作过程中望远镜支架的两个轴需带动望远镜一起转动，为了减小跟踪平台的重量和合理利用着陆器空间，又能在大范围内对太空目标进行跟踪，月基天文望远镜的俯仰轴垂直于着陆器的侧面，其转动部分固联在着陆器的侧面，方位轴采用旋转反射镜方式，将平面反射镜放在望远镜的镜筒前端，并与望远镜光轴成45°安装，使反射光线能够进入望远镜光学系统，通过转动望远镜镜筒使得反射镜实现对空间的扫描。

The sacred energy of Light Emergence Arrow draws Kirin's attention so Doug and Phoeny, who couldn't approach the Kirin before, eventually have an opening to come near it from the rear-right. But, the closer they go, the more intensive attack of fiery scales they meet. In addition, the kirin can shoot the scales only by jiggling its body and need not aim so Doug and Phoeny have to eschew these raining scales more breathtakingly. As they reach where near Kirin's neck, six scales, which roughly form a hexagon, chop toward them while turning—just like a huge meat grinder. It's thoroughly impossible to go around the scales!

光衍箭的神气吸引了麒麟的注意力，一直难以靠近它的豆豆和小凤终於有机会从它右后方接近可是越接近火鳞的攻击越密集而且麒麟只要抖动身体就能发出火鳞根本不用瞄准所以豆凤必须更加惊险的闪避如雨的火鳞等飞到麒麟颈部附近时六片大致排列成六角形的火鳞一边旋转一边向豆凤劈来就像一座巨大的绞肉机完全无法绕开！

Its main advantages are: 1 Ploughshares former can Geng Sada narrow, sharp-angle, and then a small field can be competent. 2, spiral Ploughshares high-speed rotation, tillage Shulan soil formation, may omit rake mud, soil and other pressure Suitu site preparation process. 3, spiral Ploughshares work will push the soil later, will pull the machine forward traction, it can effort can be smaller engine-driven. 4, the spiral Ploughshares work itself traction to overcome the original style, to break through resistance to the plow, the machine tray can be fitted with the lower part of farming feet deep mud paddy field. 5, the spiral Ploughshares put on the handling round, you can use the drive shaft Ploughshares handling round, 20-30 cm wide in the small mountain ridge or drive to complete removal. 6, according to the plane of principle, can also be designed as a multi-Ploughshares, or a variety of forms, suitable for large-scale farming machinery Plain.

它的主要优点是：1、犁头在前能耕狭田窄地，田尖地角，再小的田地都可胜任。2、螺旋犁头高速旋转，被耕泥土熟烂平整，可省去耙泥、压土等碎土整地过程。3、螺旋犁头工作时将泥土往后推，有将机器往前拉的牵引力，因此可以省力，可用较小的发动机驱动。4、由于螺旋犁头工作时本身有牵引力，克服了原式华犁的对闯阻力，在机器下部装上托盘就可耕作深泥脚水田。5、把螺旋犁头换上小搬运轮，就可利用犁头轴的动力驱动搬运轮，在20—30厘米宽的小山路或田埂上行驶完成搬运。6、根据该机工作原理，还可设计成多犁头或各种形式，适合平原的大型耕作机械。

In 1825 in a passage containing the first recorded instance of the English formboomerang we are told it is "a short crested weapon which the natives of Port Jackson project with accurate aim into a rotary motion."

在1825年的一篇短文中有boomerang 的英语形式的最早记录，我们被告知那是&一种杰克森港［今悉尼的一部分］土著设计的带有饰章的短武器，能在旋转运动中精确击中目标。&

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
