裂纹蛋和破损蛋在鸡蛋加工中是非常严重的问题，因为它们能够在分级和包装过程中污染机械部件，进而导致鸡蛋级别下降，因而在鸡蛋被运往分散于各个地方，设备昂贵的鸡蛋分级包装厂之前，剔除有严重缺陷的鸡蛋显得尤为重要。

There are the following several points different from existing finite element eigenanalysis methods for asymptotic fields near the crack tip:(1)The jump-off that educes the formula is different.(2)The form of the element is a ad hoc element.(3)The singular transformation technique is not used in the assumption of displacement fields surrounding the wedge tip.

该方法与过去原有求解裂纹端部近似场的有限元特征分析方法有几点不同：(1)导出公式的出发点不同；(2)单元形式为高次内插单元；(3)尖劈端部邻域内的位移场假定没有采用奇异变换技术。

3The microcosmic analysis of drill pipes: Through comparison metallographic analysis of drill pipes, this paper finds out the ultimate reason which its" performance are difference, then uses SEM to analyze drill pipes and studies crack and acanthopore, measures local chemistry component and the influence that Shot-peened to performance of drill pipes in it"s inside thickening transitional region, measures microcosmic rigidity of drill pipes.

本文的创新点：(1)提出了钻杆失效的过程和概念模型，即内表面缺陷-解理断裂-裂纹疲劳扩展-过载断裂，为解决钻杆失效分析中存在的困惑(各项基本检测参数基本合格，刺穿和断裂仍有发生)提出了分析方法和手段。

The distribution of glacial-erosion traces on the roche moutonnee has fair regularity, that is to say the long-straight striations were often formed on the top of stoss side and the crescentic scars, crescentic wedges, chatter marks and shorted striations on the end of stoss side and striation of many groups on the flanks, which can show the condition of glacial division-flow.

迎冰面的顶部为长度大且平直的擦痕，尾部为新月型裂纹，新月型凿口，颤痕和较短的擦痕；侧部常有多组擦痕，它可指示冰川分流的情况。

The 3D topography of fractured surfaces was reconstructed and quantified by the means of SEM stereo pairs, image processing and analysis, and computer vision. It was shown that measured 3D roughness indexes Rs, Rq and Rmax have good positive relations to the crack propagation part of absorbed impact energy. Although fractal behavior had been checked out on the fractured surfaces, the fractal dimension was found nonsensitive to the fracture mode and mechanical properties. The geometric characteristics of fractal fractured surfaces should be quantified in fractal dimension together with absolute parameters.

利用扫描电镜立体对技术、图像处理与分析和计算机视觉方法对示波冲击断口形貌进行了三维重建和定量分析结果表明，断口三维粗糙度指数Rs，Rq和Rmax与示波冲击裂纹扩展功有很好的对应关系，显示了它们良好的应用前景断面虽然表现出分形行为，但分形维数是一个对断裂模式和性能不敏感参量对分形断口的几何特征描述应将分维和绝对尺度结合起来

Results show that the alteration of parameters has a great influence on whether Fe3Al overlayer can be obtained or not. Cracking is the major flaw in this experiment.

研究表明，工艺参数的改变对能否获得F3Al合金堆焊层有较大的影响，裂纹是堆焊Fe3Al合金时出现的主要缺陷。

The solution: inking widgets hard and soft rollers, stereoplasm rollers which is typically the oscillating not be damaged easily; soft metal rollers are comprised of mostly made of acrylonitrile-butadiene rubber, easy swelling, surface dry aging trabeculectomies, crack or affect the normal transfer ink.

处置方法：输不朱部件有硬质和软质不朱辊两栽，硬质的不朱辊凡是为串不朱辊，是金属不难败坏；软质的不朱辊次要是由丁腈橡胶创作不收明的，便当扩张变形，暗地潮湿不解膜或老化裂纹等，感化油不朱的变态传输。

Based on analyzing and summing up the study results on deformation and fracture mechanisms of materials and member under repeated impact load,this paper shows that material defomation is characterized by plastic deformation concentrating on impact point,multi-systemes sliping difficult to perform and strain more unhomogeneous.

本文综合归纳了材料和构件在循环冲击载荷下的变形、断裂规律及机理研究成果，指出材料的变形具有多系滑移难于进行、应变不均匀性大和塑性变形集中在冲击接触点的特点；材料断裂过程为裂纹萌生、扩展和最后断裂过程，组织及实验条件对材料断裂有较大影响。

According to failure analyses of the cooling wall of No.5 blast furnace in No.1Iron Making Plant of Jigang in heavy repair in 2000, the main cause of longitudinal crack of cooling wall with ribs enchased in bricks is the temperature instability of hot side of cooling wall.

根据济钢第一炼铁厂5＃高炉在2000年大修中的破损情况，分析筋条镶砖式冷却壁纵裂原因是冷却壁热面温度不稳定，而全覆盖式冷却壁由于其结构能使冷却壁本体温度变化幅度小，且有很强的抵抗裂纹扩展的能力，因而破损速度较慢。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
