駕車者的下列行為清楚地表明了這一點：給相機噴灑顏料；撞倒相機；用喜慶的包裝紙和垃圾袋將它們蓋住；把相機挖出來；用槍射擊、用錘子砸和用燃燒彈炸；用燃燒的輪胎在上面結彩；將自身膨脹的絕緣泡沫塞進相機外殼，一旦泡末膨脹起來，能將相機撐開。Abstract : by means of metallographical examination and sem, the microstructure characteristics, macro - and microfractographs of the brittle broken wheel hull bolt of bj212 automobile have been studied. the results show that the thin - headed screw, with excessively deep carbonitriding layer and hardening layer, has less resistance to brittle fracture in the thin area of its head. at the root of the head connecting the stem, a tensile stress may emerge owing to the non - even quenching stress. those are the two reasons for low torque fracture of bolt
文摘:藉助金相、掃描電鏡等手段對低扭矩脆斷的bj212汽車輪殼螺栓的金相組織特徵，宏觀和微觀斷口形貌等進行了研究，結果表明：這種頭部薄的螺栓，滲層和淬透層過深，使頭部薄區脆斷抗力降低，在頭部與桿的根部，由於淬火應力不均勻導致根部產生拉應力，均是導致螺栓低扭矩斷裂的原因。In the first part, the method of velocity coefficient was used to design a 100mm diameter impeller with five single - arc - cylinder blades, and the method of velocity moment was applied to design the volute " s cross - section. the volute " s cross - section is a rectangle, which was designed as a whole structure with the front shroud of the pump. a special lighting window was designed on the side
在第一部分工作中，設計了一個帶半開式葉輪的微型泵：葉輪外徑100mm 、共5片單圓弧圓柱形葉片；蝸殼採用速度矩法設計，內為矩形斷面，和泵殼前蓋板為一整體、透明結構，側面專門設計一個打光窗口。Abstract : the end basket with a form of double layered conical weave net is simplified into a model of continuous conical shell - beam combined structure and in accordance with the test results of experimental modal analysis. a part of geometrical and material parameters of the conical shell in the model are identified to get an equivalent mechanical model which has the same dynamic characteristics as that of the prototype structure. by simulation and experiment, the effectiveness of the method offered is fully verified
