对甘蔗在夹持输送终点抛出后和着地时的运动学进行了理论分析，并建立了数学模型，推导出了甘蔗向外铺放的条件，以及甘蔗铺放距离、铺放角的理论计算公式，分析了圆弧轨道式柔性夹持输送装置结构参数、运动参数、甘蔗几何参数对甘蔗向外铺放、铺放距离、铺放角的相互影响规律；对甘蔗在夹持输送过程中的受力情况进行了理论分析，建立了甘蔗在夹持输送装置中所需最小夹持力模型，以及甘蔗质心距柔性夹持元件上端最大距离模型。

And the traditional passive filter's function is also limited for avoiding the resonance and harmonic enlarging. The auto-compensator and harmonics shielding converter transformer can be used to solve these problems, which is based on the principle of the winding ampere and turn's balance. This paper elaborates this kind of transformer filter mechanism. In the view of the HVDC system, a new winding connection plan is proposed, and the filter optimization model is created.

作者基于自耦补偿与谐波屏蔽的换流变压器，针对某实际的HVDC模拟系统，提出了与该变压器配套的滤波装置的接线方案，并将外罚函数法和遗传算法相结合，对上述滤波装置进行优化设计，建立了以初期投资最小为优化目标、满足系统无功需求的滤波器优化配置的数学模型。

It is could be concluded that the larger pump impeller diameter may obviously increase the efficiency of both conduit and pump system; increasing pump diameter and decreasing its rotational speed is consistent with reducing nD value.It is suitable to pump system with low head to choose lower nD value, so as a hydraulic model of axial flow pump with the better hydraulic characteristics could be obtained.

结果表明：选取较大的水泵叶轮直径将显著提高流道效率和泵装置效率；&增径降速&与降低nD值是一致的；在泵装置扬程较低的情况下，选取较小的nD值便于选用到水力性能较好的轴流泵水力模型。

The YWD series oil-cooled motor-driven Rolling Drums equipped are newest drivers for belt conveyers, which reducing speed mechanism are equipped into the drum and driving motors are equipped out of the drum. So they are also called as reducing speed rolling drum or outboard motor rolling drum. The rolling drums have many advantages such as compact construction, light weight, small size, reliable performance, convenience of installation and maintenance, etc. It can be used as driving force for fixed belt conveyers of type of TD75 and DTⅡ, which transport all kinds of loose and lumpy materials, or other cargo.

YWD型油冷外装式电动滚筒是带式输送机的最新驱动装置，它是将减速机构装入滚筒它是将减速机构装入滚筒体内，亦称减速滚筒，减速滚筒再与电机外联构成驱动装置一外装式电动滚，具有结构紧凑、重量轻、体积小、性能可靠、安装及维护方便等优点，广泛应用于TD75、DTⅡ固定式带式输送机作为动力，运送各种散状、块状特料和其他货物。

We present the case of an 11y/o girl with skeletal Class II but high mandibular plane angle, severe crowding, rotated upper first molars, and Class II dental malocclusion. Four first bicuspids extraction with a fixed appliance orthodontic treatment was undertaken.

最常被用来改正上颚大臼齿的去旋转装置就是跨颚弧线(transpalatal arch， TPA)，但是由於该装置作用范围较小对於不当旋转较大的上颚大臼齿将不易置入，且会产生过大之施力与力矩。

Fighting over the whole weight of 6-16 tons, crew 2-3 people, 8-12 people, personnel, land maximum speed: Track formula is 55-70 km time; A wheel that can be up to 100 km when the .70 since the age of some countries, additional small A-turret armored transport, installation of small-caliber guns, with automatic transmission and sound performance of the suspension.
