defect n. 1.缺陷,缺点,弱点;短处。 2.不足,缺乏。 have some defect in eyesight 目力不佳。 have the defects of one's qualities 美中不足之处。 in defect of 若无…时;因无。 vi. 叛变;逃走。 He defected to the West. 他叛逃到西方。
The analytical results show that this method can be applied in defect size prediction of pipeline in service 分析结果表明,这一方法可用于在役管道缺陷尺寸的预测。
The method chosen is based on the defect size and the availability of the remaining local skin 但对于不同的外耳轮廓缺损,应该依其缺损程度,用不同的覆盖方法加以修补,以达到最佳外观及便利性。
The result shows that the soft and hard faults will have different significance to the performance of circuits at a wide range of defect size . the relationship between yield and reliability is concerned for a long time 最后以一个4x4的移位寄存器为例,验证了该方法的有效性,最后的模拟结果给出了在不同粒径时,软、硬故障对电路性能影响程度的比较。
At last, the model of defect size distribution and the model of soft and hard faults caused by defects is given . electromigration effect is still a dominating failure mechanism of interconnect for deep submicron and ultra-deep submicron scale 然后从实际芯片的缺陷类型中抽象出了丢失物缺陷、冗余物缺陷以及介质针孔缺陷的几何模型,给出了缺陷的粒径分布模型和由缺陷引起的软故障和硬故障的模型。
With the principle of defect occurrence, a new accurate discrete yield model is deduced in this thesis . then a formula is given to show the relationship between yield and reliability, which also includes many factors with respect to design parameters such as the line width and the spacing between the lines and to processing parameters such as the distribution of defect sizes 本文首先根据缺陷的产生机理推导出了一种更精确的离散的成品率模型,然后结合该模型给出了成品率和可靠性之间的表达式,该表达式中同时考虑了与设计有关的参数,如线宽、线间距等,以及与工艺有关的参数,如缺陷的粒径分布等。
Abstract : in view of the quantity examination of weld defect by ultrasonic, on the basis of theoretical analysis and test, the cause, composition and contriling method of error of crack defect size h have been analyzed systematically, a controlling and statistical method of ultrasolic examination error has been put forward . this method is simple and suitable, and has been verified by test 文摘:针对焊缝缺陷超声波定量检测,从理论分析与实验出发,系统分析了裂纹类缺陷自身高度尺寸h的检测误差的物理成因、组成及误差控制方法,提出了一套实用简洁并经实验证实可行的超声波检测误差控制及统计方法。
