| 1. | Ultrasonic test for detecting internal defects in ceramic 超声波探测瓷件内部缺陷 |
| 2. | Terminology of internal defects in castings as revealed by radiography 辐射摄影术揭示的铸件内部缺陷词汇 |
| 3. | Internal defects : lack of penetration , lack of fusion , slag , gas pole , carck , overheating 内部缺陷:未焊透、未熔合、夹渣、气孔、裂纹、过热。 |
| 4. | Its limitation is the internal defects of weak measures , standards too much , slowly changing and difficult accumulation . 2 门)局限:第一,手段软弱;第二,标准多元;第三,转型缓慢;第四;积淀困难。 |
| 5. | The images can be used to determine the location of a surface - opening crack , an internal defect , reinforcing steel bars , or the covering thickness 所建构的影像可用以决定表面裂缝的走向及深度、内部缺陷位置、钢筋位置,及保护层厚度。 |
| 6. | The paper is based on the project of " detect of log internal defect and shape using numerical control laser and computer frequency distinguish system " 本论文是国家引进国际先进农业科学技术项目“数控激光及视频识别木材形状和缺陷技术”的基础研究之一。 |
| 7. | The occurrence probability and existence form of internal defects in rolled pieces during three - roll and two - roll cross wedge rolling were compared and analyzed by finite element numerical simulation 摘要采用有限元数值模拟方法,比较分析了三辊楔横轧与两辊楔横轧轧件内部缺陷的产生几率和存在形式。 |
| 8. | The reason that the internal defects little occur at the center points and fissure takes an annular form during three - roll rolling was expounded based on the state of stress and strain at the center of rolled pieces 根据轧件内部的应力应变状态,阐述了三辊轧制轧件中心点缺陷产生可能性较小和断裂呈环向裂纹的原因。 |
| 9. | The techniques introduced include the imaging of surface - opening cracks , the three dimensional scan of surface - opening cracks , and the imaging of internal defects using time domain or frequency domain signals 本文介绍数种利用弹性波建构混凝土缺陷影像的技术,包括表面裂缝影像法、表面裂缝三维扫描法,以及时间域和频率域的内部缺陷影像法。 |
| 10. | Therefore , in order to overcome the internal defects of the east asia exchange rate system , the dissertation attempts to probe into the issues that whether the east asia countries can closely coordinate , and how to coordinate in the exchange rate arrangement 为了克服东亚汇率体系中的内在缺陷,东亚国家能否展开东亚区域内密切的汇率协作,以及如何进行汇率协作,这是本文试图探讨的问题。 |
