  1. In this thesis hydraulic experimental studies and theoretical analyses on the vortex - flow drop shaft were conduced and the following results were accomplished : ( 1 ) in the model test some hydraulic characteristics including the shape of air core in the center of the drop shaft, the radial distribution of water flow velocity and the distribution of pressure on the wall of the drop shaft were measured under the condition of high water head above 250m and large discharge above 1400m3 / s. ( 2 ) a kind of computational method for the spiral water flow in the air core region of drop shaft was discussed and applied and the results agree the experimental data well. ( 3 ) the total ratio of energy dissipation in the drop shaft can reach 90 % and the energy dissipation in every region was discussed quantitatively

    本文通過試驗研究與理論分析對旋流式豎井泄洪洞應用於高水頭、大泄流量情況時存在的一些水力學問題進行了研究和探討，取得以下主要成果：一、結合小灣工程導流洞改建，對高水頭（ 252m ） 、大泄流量（ 1400m ~ 3 s ）條件下旋流式豎井中的水流運動特徵進行了比較全面的測量，包括空腔形態、徑向流速分佈及井壁壓強等；二、提出了豎井空腔段螺旋水流水力計算方法，其計算結果與實測值吻合良好；三、利用試驗與計算結果，對旋流式豎井的消能機理進行了探討，對豎井各部分的消能能力有了總體認識；四、對豎井下部消力井的合理井深進行了優化試驗研究，發現消力井合理深度為0 . 9d左右；五、通過試驗研究，歸納出豎井水流總摻氣量估算方法，為導流洞排氣方案的設計提供了參考依據；六、在高水頭、大流量條件下，豎井空腔段下部流速很高，盡管水流螺旋運動引起的離心力可以確保井壁壓強保持正壓，但空化數依然較低，因此豎井的空化空蝕始終是工程界關注的重大問題。

    一方面，意在消除長期以來法史學界對中國古代預防犯罪思想起源的誤解，指出早在距今約4000多年前原始社會末期的唐堯虞舜時代，就已經有關于預防犯罪的思想萌芽存在；另一方面，力求縱向探索先秦預防犯罪思想的發生、發展與嬗變歷程，闡述其基本特色，揭示其豐厚內涵，並進一步指出萌生與發展于先秦時期的預防犯罪思想，不僅對整個先秦社會產生了重大影響，對後世所產生的影響也極其深遠，值得我們今天加以分析批判和借鑒。

  4. Anthropology finds the creation of the civilization in the world context, i. e. the transformation from ancient times to societies with ranks of classes, has two basic means : one is the social fundamental changes due to the productive tools and productive means based on the breakthrough of technology, through which produced confusion with the ancient times. the other one is new era created by the establishment and maintain of the political authority and rights, from which inherited some types of institutions, views and ceremonies. thus china developed into a different legality from the west, ethical notions prevailed, no departure from criminal law to civil law, the law being a ruling way in close conformity with criminal rules ( xing ) and military rules ( bing )

    人類學上的研究成果認為，就世界范圍來看，文明的產生，即從原始社會向階級社會的轉變有兩種基本方式:一種以人與自然關系的改變為契機，通過技術的突破，通過生產工具和生產手段的變化引起社會的質變，它以兩河流域的蘇美爾文明為代表;另一種則以人與人關系的改變為主要動力，它在技術上並沒有大的突破，而主要通過政治威權的建立與維持開創了一個新的時代，它以瑪雅一中國文化連續體為代表。
  5. It was demonstrated that the values of domain strain decreased while the rate in reduction of the domain strain lowered with larger n. combined the xrd with sem results, the non - fracture mechanism of the sample when pure electric fatigue was applied can be described as : at an earlier stage of electric fatigue, the high repeated incompatible strain led the major fracture mode for the fatigued sample to be of inter - granular. the ability of domain switching in a - - > c of the sample along with the direction of an applied electric field kept dropping, hence, reduced the domain strain

    結合xrd和sem觀測，提出了純電疲勞作用下試樣不會發生斷裂的機理：電疲勞初始階段，試樣中的非協調高應變導致沿晶微裂紋，隨著微裂紋的增加，使得試樣沿外電場方向發生a c疇的能力不斷降低，從而導致疇變應變減小，當應變減小到一定程度時，將不足以在試樣中引起新的微裂紋或使原有微裂紋繼續伸長。

    即：平行於軸壓方向的測道，在軸向破裂應力的40 %左右開始下降不平行軸壓方向的測道，視電現率約在1 3軸向破裂應力開始下降3電阻率從開始下降起，下降速率逐漸增加，但增加得很緩慢，巖石大破裂前，單位軸向應力變化引起的視電阻率變化幅度也不是很大。

    為了保證本文的科學務實，文中多處通過對比分析，定性分析等研究方法，具體剖析二者不銜接方面之所在，最終得出結論：由於中考試題的簡單，以教材為中心，不注重分析問題，解決問題等能力的考察，只圍繞課本中原封未動的知識來變換題型，進而導致初中英語教學過于強調知識的準確性，而忽略了只有通過廣泛閱讀大量語言材料，不斷輸入新的語言信息才能生成的閱讀能力以及其他語言運用能力的培養，造成初中為高中在能力方面鋪墊過少，高一學生沒有具備進入高中學習所必備的相關能力等不銜接問題；而高考測試注重閱讀能力等綜合語言能力考察的導向確保了高中英語教學從起始階段就以培養閱讀能力、搜集、整理、分析、綜合各種語言信息的能力為中心等綜合語言能力為中心，由此推出初高中英語教學的不銜接問題從初中既已形成，而在高中教學中表現得尤為突出。
