internal cracking meaning in Chinese
内部龟裂
Examples
- The cement concrete pavements in cold regions often suffer from surface scaling or internal cracking under freeze - thaw cycles
寒冷地区的混凝土路面常因冻融循环而表面剥落、内部疏松开裂，影响结构的使用。 - The experiment results show that this kind of distributed strain sensor has good sensing property and high sensitivity . it can effectively identify the internal cracks of structure that occurs when the tensile stress exceed the tensile strength
试验说明，所开发的强度调制分布应变传感器具有良好的应变反应特性和较高灵敏度，可以有效识别结构拉伸应变超过极限后所产生的裂缝，对结构应变可实现定性分布测量。 - By theoretical analysis and actual measurement of field and phenomena analysis of rock burst , the author illustrates the directionless pressure , sudden movement and rupture of hard roof lead to the internal cracks of coal instable development , which easily results in rock burst happening
摘要通过理论分析、现场实测和冲击矿压现象分析，说明了顶板坚硬岩层产生的静压和突然运动、破断均可使煤体内部裂纹不稳定扩展而容易发生冲击矿压。
