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。

It was believed that either alumina reacted with impurities in the iron powder or the surface diffusion caved the alumina particles to stick to the iron powder surfaces. Another approach was to use the air classifier mill to break up the sintered iron cakes into powders. The morphology of such particles was classified into 4 types in this study: irregular, equalaxed, near spherical, and flaky. The morphological differences were affected by the extent of sintering. The higher the extent of sintering, the stronger the inter-particle bonding.

此外，本实验利用空气分级气流粉碎机将还原后的烧结体进行粉碎，实验结果显示粉碎后的粉末形貌可以分为四种，不规则形、等轴形、近球形和片形，形貌上的差异是由於还原时铁粉烧结程度的不同，烧结程度越高，粉末间键结强度越强，因此粉碎过程中会产生高程度的塑性变形，以至於粉末形貌越来越接近球形，最后因粉末表面大量加工硬化产生破裂，形成片状碎屑。

Chip sth from/off sth;chip sth off ;break or cutfrom the edge or surface of sth

他要是把他那该死的脖子折断就好了。

It is one of the most widely used methods to groove and disconnect the workpiece with the cutter,but in the process of cutting the movement of the cross-feed can reduce the working orthogonal clearance,which increases the friction between the tool flank of the cutting tool and the machined surface,and hence results in the break of the workpiece and the working tool.

用切断刀对被加工工件切断或切槽是生产中应用最广泛的加工方法之一，但在切削过程中横向进给运动的影响使刀具工作后角减小，加剧了刀具后刀面与加工表面之间的摩擦，从而会导致工件被挤断，刀具易折断。

Dr He and his colleagues knew that when certain nanoparticles (which have diameters of only a few billionths of a metre), are spread over glass they break the surface tension of the droplets as they try to form.

贺博士及其同事了解到，一些直径仅为几个十亿万分之一米的纳米颗粒在玻璃表面覆盖，能打破水滴形成过程中的表面张力。

On bright, calm days they lie in thousands on the now darkening water, mostly yellow flotillas of poplar, floating continuously down from great trees that themselves shake in the windless air with the sound of falling water , but on rainy days or after rain they seem to swim or be driven away, and nothing remains to break the surface except the last of the olive-yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain...

当风和日丽时，无数的树叶浮在已经变暗的湖水上，大部份都是白桦叶子，他们一批一批，像黄色的小小扁舟，不断地从高高的树上飘落下来，在无风的空气中轻轻地晃动着，发出如同流水而下的声音。但是在下雨的时候，或者雨过之后，那些浮在湖面上的落叶，仿佛鱼儿一样都游走了，又像是被不知什么驱赶一空，湖面上除了最后的几片黄绿色睡莲叶子，再无一物，而在盛夏里，那些睡莲叶子，如同翠绿晶莹的瓷盘，覆盖着每一寸湖面。

On bright calm days they lie in thousands on the now darkening water mostly yellow flotillas of poplar floating continuously down from great trees that themselves shake in the windless air with the sound of falling water but on rainy days or after rain they seem to swim or be driven away and nothing remains to break the surface except the last of the olive- yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain.

在风和日丽的日子里，白杨树叶伴着水流的节奏簌簌地落下，像一叶叶黄色的扁舟，成千上万地泊在这秋水中。在下育的日子里或育后时节，它们或游离此地，或随波逐流。平静的湖面上只剩下残存的黄绿色的睡莲叶子。而盛夏时，睡莲叶子宛如葱绿晶莹的瓷盘，覆盖着湖面的每寸水域。睡莲凋零了。

这些数叶大多是杨树叶，如一列列黄色小艇般不停地从那些无风也簌簌的高大树木上落下来，落雨般淅淅沥沥。但是在雨天或雨后，它们却飘得无影无踪，或像被什么赶走了，此时湖上只剩下橄榄黄色的睡莲碎片，在盛夏时，碧绿的莲叶曾像盏盏翡翠玉盘一样把整个湖面盖得密不透风。
