When the rotor bearing journal of turbine-generator unit and the collector ring of generator are damaged, we can restore them on-line by TR series which are the systems that the rotor bearing journal of large-scale rotary machine is lathed subtly on-line and burnished.

汽轮发电机组的转子轴颈和发电机的集电环损伤可利用TR系列&大型回转机械转子轴颈在线精车与珩磨系统&进行在线修复，其精度可达到国际先进水平，在线修复可避免大范围拆装主设备，避免返厂加工的长途运输，可节省大量的检修时间，具有显著的经济效益。

Methods: The tenderness of normal points in subjects with acute neck pain were firstly diagnosed with current diagnostic method, secondly were measured with tonic measurement system of local soft tissue, then whose stress-strain curves were analysized to find proper indexes reflexing the difference.

采用自制软组织张力测试系统，观察急性颈痛患者自身压痛点及无压痛点的力－位移曲线，分上颈椎、下颈椎及颈肩背部等三部位，对生物力学指标按照&压痛点&、&无痛点&配对比较。

METHODS: Bilateral common carotid arteries of rats in the ischemia and treatment groups were splinted for 30 minutes and reperfused for 1 hour to establish models of isehemic cerebral injury.

缺血组和治疗组大鼠夹闭双侧颈总动脉30min后再灌注1h，建立缺血性脑损伤模型；治疗组在缺血30min前腹腔注射参麦注射液2mL／kg（由红参、麦冬等中药组成）；缺血组不给药；对照组做假手术，不夹闭颈总动脉，也不给药。

Well, the blade transected the jugular vein and both carotids.

A set of measurement system for bearing and axle journal on passenger car has been developed to fulfill the work of measuring the dimension,data saving,communication and data management,which overcomes disadvantage of manual measurement,such as low efficiencies,high cost,high labor intensity and low precision.

针对铁路客车轴承与轴颈人工测量效率低、成本高、劳动强度大、精度差等缺点，研制了一套客车轴承与轴颈尺寸的测量系统，能够完成尺寸的测量、数据存储、通信和管理工作。

By employing coordinate transformation, the overall generalized displacement vector relevant to the motion of pad and axle journal is converted into axle journal displacement vector in a local motion coordinate system, and the oil film force in a partial motion coordinate system is obtained by solving the dynamic characters of a fixed bush bearing.

通过坐标变换，将瓦块和轴颈运动相关的全局广义位移矢量转换为局部动坐标系下轴颈的位移矢量；利用求解固定瓦轴承动力特性的方法求得的局部动坐标系下的油膜力。

The results show that the pad tilting angle in static equilibrium is related to the structural parameters of pad, eccentricity of axle journal to pad, and elearance ratio, but is unrelatrd to the axle journal speed, viscosity of oil film, etc.

研究表明，瓦块静平衡摆角只与瓦块结构参数、轴颈相对瓦块偏心率，间隙比有关，而与轴颈转速、油膜粘度等无关。

The assembly of journal and plain bearing liner space is too little, force of organic still oil pressure is small it is the crucial index that affects lubricant result, make lubricate because of lacking engine oil between crankshaft and plain bearing liner and bite dead invalidation, include to be pulled badly, lack lube, layer of alloy of dry attrition generation is fused, grind sliding surface to did not maintain the oily film of certain ply, and all sorts of local overload exhaustion are destroyed, cavitation erosion and V form are destroyed etc, through technology of him director diesel locomotive old experience reachs the analysis of pair of its breakdown reasons, put forward precautionary measures especially. As a result of,the burns caustic mechanism plain bearing liner to burn caustic mechanism of 1 plain bearing liner is the lube film burst between journal and plain bearing liner, cause plain bearing liner and crankshaft generation clash, below high temperature, high pressure and high rotate speed, the wear-resisting alloy layer of plain bearing liner wears away prematurely or fuse, cause plain bearing liner and crankshaft to stick thereby bite, can make the steel back of plain bearing liner and Kong Zhong produces whirligig, inlet port is jammed, carry on the back by steel again with the friction of aperture causes high temperature to make plain bearing liner burned-out further, can cause bolt to break off, happen swing a malign accident that pounds cylinder body of bad internal-combustion engine.

轴颈和轴瓦的装配间隙太小，还有机油压力低是影响润滑效果的关键指标，使得曲轴和轴瓦之间因缺少机油润滑而咬死失效，包括严重拉伤，缺少润滑油，干摩擦产生合金层熔化，磨滑面没有保持一定厚度的油膜，以及各种局部过载疲惫破坏，气蚀和V形破坏等，通过本人主管内燃机车技术多年经验及对其故障原因的分析，特提出预防办法。1轴瓦的烧损机理轴瓦烧损的机理是由于轴颈和轴瓦之间的润滑油膜破裂，导致轴瓦和曲轴产生摩擦，在高温、高压和高转速下，轴瓦的耐磨合金层过早地磨损或熔化，从而引起轴瓦和曲轴粘咬，会使轴瓦的钢背和座孔中产生旋转运动，进油孔被堵塞，再由钢背和座孔的磨擦进一步引起高温使轴瓦烧坏，并会造成螺栓折断，发生甩出捣坏内燃机缸体的恶性事故。

There is something else that I don't like about cat flea collars, or dog flea collars.

有东西，我不喜欢猫蚤颈圈，狗蚤颈圈。
