  1. Electrons which pass through the thin specimen are brought to a focus in the back focal plane of the objective lens, this lens, like all electromagnetic lenses, acts as a converging lens and thus forms a diffraction pattern in this b. f. plane

    穿越薄樣本的電子被帶到目標鏡背面焦點平面的一個焦點,這個鏡,象所有的電子鏡一樣,充當了聚焦鏡的作用,因此,了在這個背面焦點平面的衍射模式。
  2. 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;由於的不同,非穿切口樣品和穿切口樣品的聲發射空間分佈特點有本質區別,穿切口樣品的微破裂在切口兩端發育,而非穿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;含共線的巖石,裂紋外端的聲發射分佈與單裂紋中裂紋端部的聲發射分佈相似,裂紋內端聲發射有密集分佈,在應力達到一定水平時,內端部發生錯斷,而不是貫通。
  3. In the process of building and using the mass concrete structures, because of the effect of out - side condition and themselves, some faults will form in the structure, these faults will effect the bearing capability and endurance using nondestructive testing method to test the concrete ' s quality and diagnose its healthy, which has the significant sense in assessing the safety stability and research of the administering diseases this dissertation mostly researched the testing methods in the mass concrete structure, discussed the principles, methods, features, sphere of application of the ultrasonic testing in the mass concrete structure with faults, used dynamic fem to simulate the testing process, discussed when the concrete structure with cracks is under the effect of the pulse, how the elastic waves propagate and what are their changing feature, researched the principles of the first - arriving waves " phase when the cracks " depths are not same, obtained the relation between the inversion point and the cracks " depth, which has the direction sense in the application of projects, the second part of this dissertation is ct, which used the ultrasonic wave running through the tested - substance to get arriving - time of the ultrasonic wave, then inverse the image this dissertation drawed one ct program which can well present the different little cells " ultrasonic wave velocity profiles of the substance, thereby to diagnose the quality of the part of the tested - substance, ct has the better using foreground.

    在混凝土結的施工及使用過程中,由於受其自身及外界各種因素的影響,常常會產生一些缺陷,對結物的承載能力和耐久性成嚴重影響,採用無損檢測技術進行質量檢測和健康診斷,這對混凝土結開展安全、穩定性評估以及病害隱患治理研究具有重要意義。本論文主要針對大體積混凝土結缺陷的檢測方法展開研究工作,重點討論了超聲波法檢測混凝土結裂縫的基本原理和方法及其特點、適用范圍,運用動力有限元數值模擬其檢測過程,探討了有裂縫缺陷的混凝土結在脈沖荷載作用下彈性波的傳播及其變化特徵,研究了不同裂縫深度下首波相位變化規律,得出了反轉臨界點與裂縫深度之間的關系,這對實際工程應用具有指導意義。聲波ct是一種新的無損檢測技術,它是利用聲波穿被檢測體獲取聲波接收時間,來進行計算機反演成像的技術。
