In order to reduce the axle journal of mechanical strength loss, grinding the shaft seating surface wear uneven Department just to Polish it, and then to the journal after Polish excircle size, choose a higher wear resistance ZQAl7-1.5-1.5 bronze, confecting a plain bearings again, replacing the original linear ball bearing.

为了减多轴颈的板滞强度吃亏，磨削的尺寸以轴颈表背磨损不服处恰好磨平为好，再以磨平后的轴颈外方尺寸为基准，采取耐磨性能较矮的ZQAl7-1.5-1.5青铜合金，从头配制一只滑动轴承，替代本来的曲线滚珠轴承。

Special attention should be directed to the upper cervical spine and especially to C1-2, where subluxation may result in the development of serious neurologic complications.

特别的注意应该指向上面的颈背骨而且尤其到 C1-2 ，次脱臼可能哪里造成严重 neurologic 复杂化的发展。大慨是这个意思了！

The TCM symptoms of hypokinesia, muscle rigidity, bradykinesia, nape rigor, diziness, insomnia and dreamful sleep, sore waist, skelalgia and constipation in treating group has improved than that in controlled group. Compared with placebo group, the"off"time of patients in NKN group reduced 27% averagely; the"on" time prolonged 19% averagely.

脑康宁组证候总有效率76.67％，对照组为50.0％，两组比较有显著差异（P＜0.05）；脑康宁组肢体拘挛、运动迟缓、颈背僵直、头晕、失眠多梦、盗汗、腰酸腿痛、便秘等症状均有明显改善（P＜0.05）；脑康宁组用药后&关期&平均减少27％，&开期&平均延长19％；用药后生活质量评分的各方面均有明显改善，且与对照组比较有明显差异。

It suggests that many plumage features are/can be shared by all three of Pallas's/Middendorff's/Styan's, including blackish-looking greater coverts, white tips to inner web of one or more tertials, white tips to tail feathers and greyish on face/nape, so birds need to be identified on a combination of features.

它建议许多羽毛特徵是或可能是被小蝗莺/北蝗莺/史氏蝗莺共用的，包括看起来带黑色的大覆羽，一或更多根三级飞羽内侧羽瓣的白端，尾羽的白端，以及带灰色的脸/颈背，所以必须以这些特徵综合来辨识。

Within the constraints of the research published to date, it appears that hookers and props have been at disproportionate risk of cervical spine injury, predominantly because of injuries sustained during scrummaging.

在研究的限制里面出版约会，它出现那 hookers ，而且支柱已经在颈背骨受伤的不成比例危险，居多因为受伤在聚合排成争球队形的时候维持。

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。

If these abnormities were laid according as frequency among 2-6 months,reflex abnormities are knee tendon reflex, palmar grasp reflex,...
