裂纹

The large banded structures would lead to break during drawing.The intermidiate ones would result in extensible crack but not result in break during drawing.The small ones could exist inside the wire in the form of incontinuous particulates,resulting in a decrease of the p...

粗大的带状组织将直接导致拉丝断裂；稍小一点的带状组织不会引起拉丝断裂，但在钢丝内部存在着明显的非稳态扩展裂纹，是不安全的；细小的带状组织不会引起拉丝断裂，最终将以断续的点状形态存在于成品钢丝中，但对其安全性存在重大隐患。

The large banded structures would lead to break during drawing. The intermidiate ones would result in extensible crack but not result in break during drawing. The small ones could exist inside the wire in the form of incontinuous particulates, resulting in a decrease of the performance of wire.

粗大的带状组织将直接导致拉丝断裂；稍小一点的带状组织不会引起拉丝断裂，但在钢丝内部存在着明显的非稳态扩展裂纹，是不安全的；细小的带状组织不会引起拉丝断裂，最终将以断续的点状形态存在于成品钢丝中，但对其安全性存在重大隐患。

This study comes from the "incontrollable problem at last stage" in blanking workpiece with non-symmetrical geometry in the bearing industry, which means the crack propagates beyond the pre-cut V-notch field at the last stage.

本文是针对轴承行业中几何非对称断料的&后失控&问题(裂纹扩展后期扩展路径超出了预制的环形V型切槽范围)提出的。

During the process of fracture toughness test of 7150 alloy extrusion,the prior fatigue crack initiated and propagated inhomogeneously.

在准备7150合金平面应变断裂韧性试样的过程中，预制疲劳裂纹发生不均匀扩展。

Thermal fatigue cracks which occurred to the weak position were intercrystalline in origin and mode of prop...

其热疲劳裂纹在构件薄弱处出现，萌生于晶界，并沿晶界扩展。

Through the comparison of this model with Miller and Smith's shear cracking model, it can be shown that the smaller the interlamellar spacing of pearlite is, the higher the resistance of crack initiation and propagation will be.

该模型与Miller和Smith提出的剪切开裂模型的比较可以说明，珠光体片层间距越细小，裂纹萌生和扩展的阻力越大。

The adhesion wear of the coatings is somewhat different from the sintered or cast materials, which could be explained in terms of interlamellar cracking and flaking off of lamellae.

涂层的粘着磨损显示出不同于块体材料的粘着磨损的特点，表现为粘着力引起涂层层间裂纹扩展和层状颗粒剥离。

This result can be used to explain not only the microhardness and elastic modulus of coatings changing with respect to measurement direction and locations, but also the wear mechanism of interlamellar cracking and flaking off when intense adhesion took place between wear parts during sliding.

从而解释了在压头载荷作用下，由于层间裂纹扩展的强弱不同，而使涂层的显微硬度和弹性模量的测量结果随测量方位和压头取向发生变化。

The stitching method to enhance interlaminar toughness of stitched-laminates was mainly discussed in this paper based on our research and experiment.

在缝合式层间强度的提高研究中，从断裂力学的角度，采用作为层间裂纹扩展阻力的能量释放率来评价层合板复合材料的层间断裂韧性。

But because of the exiting of much stress contained in the dry silicon gel, the membrane would be much crack in the process of calcinations. As a result, the Knudsen contribution to the total flux for N2 was about 70% and 85% for A and B tube, respectively.

但是在焙烧过程中由于干硅胶和MCM-48膜的应力释放而产生较多裂纹，导致在膜对N2的总渗透通量中努森扩散只占到70%和85.7%。

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。
