A conclusion can be drawn that the land market in the rural area and the urban area in our country are dissevered by the faulty land right system and the binary economic structure engendered due to the history cause. such land institution lead to many problems in the land resource allocation. firstly, the land in the rural area should shift, in order to meet the need of the urbanization, the development of the group enterprise and the change of labor structure in the rural area, but there are obstructions in the legal system, which lead to farmland and construction land shifting illegally
在這種制度安排下導致我國土地資源配置中出現諸多問題:城市化的發展、鄉鎮企業發展以及農村勞動力結構變化都要求農村土地入市,但是法律上卻存在著障礙從而導致農地非法非農化和建設用地自發交易;在不完全的土地產權體系中農村集體和農戶利益受到侵害;國家利益隨著劃撥土地入市而大量流失;在割裂的土地市場制度下土地價格體系也出現城鄉割裂,農村集體土地不論是農用地還是非農用地的價格都未得到科學的界定和規范。The experiment was carried out at the lawrence berkeley national laboratory ( u. s. a ). a 252cf was placed at the center of the gammasphere detector array which, for this experiment, consisted of 102 compton - suppressed ge detectors. by measuring prompt - ray of spontaneous fission from 252cf, a total of 5. 7 1011 triple - and higher - fold coincidence events were collected
實驗工作是在美國洛侖茲伯克利國家實驗室( lbnl )的gammasphere探測裝置上完成的, 252cf自發裂變源放置在一個由102個反康ge探測器組成的gammasphere探測器陣列的中心,測量自發裂變產生的瞬發譜,記錄三重以上的符合事件。In view of the rapid development of electric undertaking and a sharp increase of steel products consumption, the state development planning commission, the former state water resources and hydropower ministry and state energy ministry have been urging that the building of steel towers should be strictly controlled in the construction of transformer substations ; and warning that the need of the present 500kv power transmission and transformer trusses can hardly be satisfied by ordinary steel and concrete electric poles or prestressed concrete poles, which have endangered the operation and longevity of the high voltage transmitting line due to the common problem of cracks by gravity
隨著電力工業建設的迅速發展,鋼材的用量急劇增長,為此,國家計委,原水電部和能源部一再強調在輸變電工程建設中,應從嚴掌握自立式鐵塔的建設。然而,一般的鋼筋混凝土電桿或與預應力混凝土電桿,較普遍地存在著縱向裂縫問題,嚴重影響了高壓輸電線路的安全運行及其使用壽命,已不能適應高壓輸電桿塔和變電構架的要求。The microprocesses of deformation and fracture in 18 - 8 stainless steel were observed by in - situ tension in tem. it was found that the dislocations were emitted from the grainboundary and dislocation source inside a grain and slip along their slip system respectively. partial dislocation could also be emitted from the grainboundary, and moved into the grain, and that leaving behind a stacking fault
摘要浙江人學博1 :學位論文採用透射電鏡動態拉伸、原位觀察icrlsnigti不銹鋼形變與斷裂過程,發現不銹鋼變形時,晶界和晶內位錯源均可產生位錯,並沿各自的滑移系運動。分享友人
