1·Surface crack has been founded on the normal rolling steel.

某轧钢厂正常轧制的钢材表面存在裂纹缺陷。

2·Surface crack includes horizontal, vertical and reticulate crack.

表面裂纹又分为横向裂纹、竖向裂纹和网状裂纹。

3·All of these tests are used to detect surface crack discontinuities.

所有这些测试是用来检测表面裂缝不连续性。

4·The surface crack fracture toughness KIe of D406A steel were tested.

测定了D406A钢表面裂纹断裂韧度。

5·Surface crack of steel components was repaired with two bundle of laser.

采用双光束激光修复碳钢零件的表面裂纹。

6·The evolution feature of surface crack shape is analysis too in this paper.

同时还对含表面缺陷钢管裂纹形态的疲劳扩展演变规律进行了分析。

7·Subsurface inclusion is one of the reasons causing surface crack of rolled steel.

皮下夹杂是造成表面裂纹的原因之一。

8·The crack occured in silica brick generally includes surface crack and layer crack.

硅砖中裂纹包括表面裂纹和层裂。

9·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。

10·Then the K resemble theory was used to translate the surface crack to middle through crack.

并利用K相似原理，把表面裂纹问题转换为中心贯穿裂纹问题；
