查询词典 failure

It is clarified for the first time that the thermal fatigue failure of solder joint is actually a creep strain low cycle fatigue failure, and a physical model for creep fatigue crack propagation has been proposed. It was pointed out that creep strain increases in the high stress area ahead of the tip of thermal fatigue crack, results on one hand that the slide of crack tip increase, inactivation more serious and crack close length increases, the other hand, that intergranular crack exists, whose direction will affect the fatigue crack propagating.

本文首次阐明了焊点的热循环失效本质上是以焊点内循环蠕变为主要应变的低周疲劳失效，并在此基础上提出了蠕变疲劳裂纹扩展的物理模型，指出热循环裂纹前端的高应力区内，蠕变加剧，使裂纹前端滑移增加，裂纹钝化加剧，导致随后的裂纹闭合扩展长度增加；同时蠕变也使裂纹前端的高应力区出现晶间裂纹，蠕变沿晶裂纹对主裂纹扩展的影响取决于沿晶裂纹的连接方向。

The results show that coils' failure rate and probability are biggest, and tap switches' failure rate is also high.

This will lead to roll failure such as fire crack, surface crack, and fatigue failure.

这将会导致轧辊疲劳产生热裂、轧辊表面破裂或是疲劳层的产生。

It was also found that the strength of FF specimen is close to the sumation of the strengths of FC and FS specimens with the same board thickness and screw spacing as FF specimen. As compared the test results with the research findings from Li [2]and Luo [3], It can be concluded that the failure mode of specimen is affected by both the sheathing thickness and the stud thickness. Different from this study, the failure mode of Li's test specimens is torsional-flexural buckling for most cases. The predicted values computed based on the AISI Specification seem to be conservative as compared to the tested values of FF specimens. Therefore, it is suggested that the effective length factor, K, can be taken as 0.5 to determine the wall stud assembly strength.

在三种不同试体组合分析时也发现，具外覆材支撑之立柱与外覆材受压内含支撑之立柱，两者之破坏强度相加，约等於具外覆材之墙体之破坏强度；试验结果与李岱真、罗浩之研究比较后，发现不同厚度之立柱与不同厚度之矽酸钙板之间束制关系明显影响强度之差异，且李岱真之试体破坏模式多为整体扭转-挠曲挫屈破坏，与本研究有较大差异；对於具外覆材之墙体与AISI预测值比较后，AISI规范预测值较保守，因此本研究有效长度系数建议采用0.5。

Slope failure along fracture in rock mass is the basic form of rock slope failure.

边坡沿岩体结构面的破坏是岩石边坡变形破坏的基本形式。

From all the work a set of complete methods of analyzing and calculating fatigue reliability of structure systems are put forward. The fatigue reliability of structure systems can be calculated by searching failure modes and using the series-wound model composed of the failure modes.

由此针对结构系统疲劳破坏的特点，本文提出了一套完整的结构系统疲劳可靠性的分析和计算方法，该方法通过搜索结构系统的主要失效模式，应用失效模式组成的串联模型计算结构系统的疲劳可靠性。

They tell children so often that it will be a great disappointment if they do not measure up ,"says Bonaro W Overstreet, in Understanding Fear,"that they virtually force those children into an exaggerated fear of failure, and into an exaggerated self-dislike when failure occurs.

实际上他们是在强迫孩子们放大对于失败的恐惧感，在失败时对自己产生过度的厌恶心理。

It was shown that coal seam floor failure depth of working face 2121 was 32.5 to 5 m, approximately three times as deep as that of shallow working face(in genera l,9.15 to 12.0 m). Coal seam floor failure depth increased with mining depth. Potential risk of water inrush through coal seam floor of working face 2121 is much higher for deep mining than for shallow mining.

试验结果表明：该工作面底板破坏深度为32.5~35 m，比300 m采深以内的工作面实测深度(9.15~ 12.0 m)增加2倍以上，说明随着开采深度的增加，煤层底板采动破坏深度呈明显增大的趋势，因此，在水压和破坏深度二者同时增加的条件下，2121工作面深部煤层开采的突水危险性远远大于浅部煤层。
