巖石亞臨界裂紋擴展試驗及門檻值研究The student said " hello " to all of us when we met him. he was thin and his face was black, seems that he was undernourished. his father brushed the chairs with his sleeves immediately, asked us to sit down. his mother leaned the door with foolish smile all the time. it was even poorer of their family than our thought. the lime had started to come off as the wind and rain damage, the sunshine got through their house, shadow was remained on the sap of floor. two small rooms, a kitchen, a quadrate desk and some chairs here, there were not anything else ; the other one was bedroom, two beds were squeezed together. the bedding wasn ' t new any more and turned white, cotton was come out from the clothes. the only thing was what one old desk was cleaned well, it should be his book desk, there were some books on it

這間小屋用一條扁平的石頭做門檻。It is found that cyclic loading at high differential stress level will lead to the decrease of felicity ratio, and the value max can be decreased by some crack systems in specimen. there is still a lot of ae during unloading at high differential stress level, which implies that the deformation is dominated by fracturing at low differential stress level, and the deformation by frictional sliding increases greatly at high differential stress level
關于應力方式對巖石破裂的影響，發現較高差應力水平下的多次循環加卸載會使felicity比減小；某些構造能使巖石產生felicity效應的應力門檻值_ （ max ）降低；由高差應力水平下卸載時仍有大量聲發射產生推測：在低差應力水平下，破裂以裂紋尖端的突然擴展為主；在高差應力水平下，沿已有的裂紋面的滑動破裂大量增加。分享友人
