Barrier cracks cannot stop the extending of a fracture , and the strength of the sample is reduced by almost one magnitude because of the existing barrier cracks . there are great differences of ae distribution between specimens with non - penetrate crack and specimens with penetrate crack . as for penetrate crack , ae occurs near the two end of the crack , and for non - penetrate crack , crack , ae occurs near the two end of the crack , and for non - penetrate crack , ae occurs near the front edge of crack , which can be explained well by the theory of 3 - d fracture ; ae distribution near the outer part of collinear crack is similar with that of the end of penetrate crack , and inner part of collinear cracks will run - through with high loads 關于預制裂紋系對巖石破裂的影響,集中討論了:空障礙體構造不能阻止主裂紋的擴展,反而會使巖石的破裂強度降低近一個量級;由于構造的不同,非穿透切口樣品和穿透切口樣品的聲發射空間分布特點有本質區別,穿透切口樣品的微破裂在切口兩端發育,而非穿透切口樣品的微破裂在切口兩端之間切口前緣處發育,這用三維破裂理論可以很好地解釋;含共線構造的巖石,裂紋外端的聲發射分布與單裂紋構造中裂紋端部的聲發射分布相似,裂紋內端聲發射有密集分布,在應力達到一定水平時,內端部發生錯斷,而不是貫通。

Next , the effects of the electron - beam quality on the characteristics of the vircator are investigated with simulation method . the simulation results show that the front edge of the beam pulse has almost no effect on the saturated microwave output , while good front edges can accelerate the saturation of the virtual cathode oscillation , and beam quality ( except its energy spread ) has almost no effect on microwave frequency , and so on 結果表明:上凸形束脈沖前沿可使虛陰極振蕩器達到飽和振蕩的時間縮短但對微波飽和功率基本無影響;束流脈寬應足夠大,否則虛陰極振蕩器不能達到飽和振蕩(對應本文中的模型,束脈寬應大于16ns ) ;能散度的影響不可忽視,當能散度為5時,束波轉換效率從單能束時的3 . 8降至1 . 5 ;束流質量(除能散度外)對微波頻率基本上沒有影響等。

In view of the engineering practice that retaining wall in the front edge of landslide is only deformed but not destructed completely as a result of the slide of slope , this paper presents a back calculation method of landslide shear strength index considering the residual resistance of retaining wall occurring topple , translation and shear deformation 摘要針對滑坡的滑動僅使其前緣的擋墻發生位移或變形,但未使之完全破壞的工程實踐,系統提出了滑坡前緣的擋墻在發生傾覆、前移和剪切三種變形下,考慮擋墻變形后對滑坡的剩余抗滑作用進行滑帶土抗剪強度指標反算的理論和方法。
