The hanging strip device includes: a hanging strip device main body; a winding section for performing the winding of the hanging strip; a winding auxiliary section, which is configured at a state that the rotation relative to the hanging strip device main body is limited and can move between the first preset position and the second preset position relative to the winding section, wherein, at the first preset position, the rotation of the winding section makes the hanging strip wrap is restricted, at a second preset position, the winding section can perform the drawing-out rotation for drawing out the hanging strip; a force applying part, which applies a press pressure to make the winding auxiliary section at the first preset position; and a convex part which allows the winding auxiliary section to be at preset point contact status relative to the hanging strip device main body when the winding auxiliary section is at the first preset position.

置在该吊带装置主体内，而且能够在第一预定位置和第二预定位置之间相对于上述卷绕部移动，其中，在上述第一预定位置，上述卷绕部的使上述吊带回绕的旋转被限制，在上述第二预定位置，上述卷绕部能够进行用于抽出吊带的抽出旋转；施力部，其施加将上述卷绕辅助部按压向上述吊带装置主体的按压力，以使该卷绕辅助部处于上述第一预定位置；和凸起部，其设置于上述卷绕辅助部或者上述吊带装置主体的任一方，在该卷绕辅助部处于上述第一预定位置时，上述凸起部使该卷绕辅助部相对于上述吊带装置主体成为预定的点接触状态

The path the racket travels along looks very similar to a "C." By doing these three things at the same time you'll get to your contact point, which is a little bit out in front of your body and about waist-high.

拍头挥击路线象一个&C&字形，在同一时间完成上面三件事，你将找到你的击球点，击球点是约与腰齐高，身体前面一点点地地方。

Based on the wheel/rail multi-point contact in turnout zone, a dynamic design theory for high-speed railway turnout was established and several creative designs were made, such as separated semi-tangent switch plane linetype, horizontal hidden nose structure of turnout frog, short transitional top surface figure of the switch rail, and track stiffness of turnout with even elasticity.

基于道岔轮轨多点接触关系，建立了高速道岔动力分析理论，并设计出适合我国高速道岔的相离式半切尖轨平面线型、心轨水平藏尖结构、尖轨短过渡顶面轮廓和弹性均匀的岔区轨道刚度。

At this point, electrical components and not as a result of poor contact suck-in so that it heats the electromagnetic clutch coil of insulated would be premature, finally burnt down.

此时，电气元件由于隔绝不良而不呼分，使其温量贬低，制不静电磁离分器线圈的绝缘便会过早受到保护，以致末了被销毁。

In this paper, we proved that there exists only one contact point between a pair of non-circular gears working under the designed pitch curves when they are manufactured by involute cylindrical gear cutter in numeric control slotting machine. Under this manufacturing condition, the pair of non-circular gears can mesh accurately.

证明了采用渐开线圆柱齿轮刀具在数控插齿机上加工的1对非圆齿轮副传动时，在其按设计的已知节曲线工作时，两非圆齿轮副的齿廓具有单一的接触点，即能保证正确的啮合关系，为深入分析非圆齿轮副的传动机理提供了前提。

It is shown that the contact interaction enables bottom drillstring to whirl backward, and then an alternate bending stress with higher frequency is produced. So the drillstring fatigue failure could be accelerated. At the same time, a quite strong wallop force of high frequency is produced on the contacting point, and the contacting zone is next to the screw coupling of drill collars. It will easily result in the failure of screw couplings. The research results provide theoretical basis for the prevention of drillstring failure.

研究表明，下部钻柱与井壁的碰摩作用使下部钻柱反向涡动，产生高频的交变弯曲应力，会加速下部钻柱疲劳破坏；下部钻柱与井壁接触点处存在较大的高频冲击力，并且接触区域靠近钻铤螺纹联结处，更容易诱发螺纹联结处失效，该研究成果可为预防钻柱失效提供理论依据。
