  2. At the initial stage of planar technique, b was employed as ideal diffusion impurity in base - region of npn si planar devices because of the match of its solid - solubility and diffusion coefficient in si with those of p in emission - region, and the good shield effect of sio2 film to b. but because of the relatively large solubility ( 5 1020 / cm3 at 1000 ) and the small diffusion coefficient, the linear slowly - changed distribution of acceptor b in pn junction can not be formed, which could not cater to the requirement of high - reversal - voltage devics. thereafter b - a1 paste - layer diffusion technology and close - tube ga - diffusion technology had been developed, while the former can lead to relatively large the base - region deviation and abruptly varied region in si, which caused severe decentralization of current amplification parameter, bad thermal stability and high tr ; the latter needed the relatively difficult pack technique, with poor repeatability, high rejection ratio, and poor diffusion quality and productio n efficiency

    在平面工藝初期，由於b在硅中的固溶度、擴散系數與n型發射區的磷相匹配， sio _ 2對其又有良好的掩蔽作用，早被選為npn硅平面器件的理想基區擴散源，但b在硅中的固溶度大（ 1000時達到5 10 ~ （ 20 ） ，擴散系數小， b在硅中的雜質分佈不易形成pn結中雜質的線性緩變分佈，導致器件不能滿足高反壓的要求，隨之又出現了硼鋁塗層擴散工藝和閉管擴鎵工藝，前者會引起較大的基區偏差，雜質在硅內存在突變區域，導致放大系數分散嚴重，下降時間t _ f值較高，熱穩定性差；後者需要難度較大的真空封管技術，工藝重復性差，報廢率高，在擴散質量、生產效率諸方面均不能令人滿意。
  3. On the other hand, relationship between doping concentration, phase transition temperature, magnitude of resistance change and hysteresis width was investigated

    在此基礎上，本文進一步探討了摻雜濃度與vo _ 2薄膜相變溫度、電阻突變數量級以及熱滯寬度的關系。
  4. Then, the effect of vacuum annealing temperature on vo _ 2 thin film phase transition temperature, magnitude of resistance change and hysteresis width by doping zr ~ ( 4 + ) was discussed

    （ 2 ）本文以摻鋯為例，探討了不同的真空退火溫度對vo _ 2薄膜的相變溫度、電阻突變數量級以及熱滯寬度有何影響。
  5. Results show that the increase of semiconductor - metal phase transition temperature and the decrease extent of resistance is linear to zr ~ ( 4 + ) doping content, while the hysteresis width of vo _ 2 thin film fluctuates with zr ~ ( 4 + ) doping content

    實驗結果表明:隨zr含量的增加， vo _ 2薄膜的半導體-金屬轉變溫度和電阻突變數量級呈線性下降，同時，隨摻雜量的增加， vo _ 2薄膜的熱滯寬度的變化規律是先減小后增大。
  6. This change is a break when the outside conditions exceed a threshold value with gradually variety. the break is equal to the non - equilibrium phase transition in thermodynamics. ( 6 ) there are two kinds of stable channels

    河型轉化是在外界條件緩慢變化過程中，超過某一臨界值而發生的突變，這種突變相當于熱力學中的非平衡相變，是由某些參數的漸變引起的從量變到質變的一個過程。
  7. And the value drop to the lowest at ph = 0. 8. as the increase of heat treatment temperature, the pore size distribution peak of sio2 microspheres is very narrow, meanwhile the specific surface area is the smallest before 160 c. the polymer template is removed at 350 c, so the pore structure of sio2 particles has a big change which involve the increase of specific surface area and the broaden of pore size distribution peak. with the continuous raise of temperature the sio2 network will shrink little, as a result the average pore size will decrease, but the specific surface area has no obvious change

    結果發現：二氧化硅膠體顆粒均勻分佈於脲醛聚合物網路中，煅燒去除有機模板后微球表面變粗糙，而粒徑沒有明顯變化； ph值較小時，復合微球中聚合物含量較大，而ph值較大時，得到復合微球結構鬆散，因此熱處理后的二氧化硅微球孔容及平均孔徑都較大，而在ph = 0 . 8時，得到最小值；武漢理工大學碩士學位論文隨著熱處理溫度的變化，小於160時，空分佈較窄，而比表面積較小，在350時，由於有機模板的去除，微球孔結構發生突變，比表面積明顯增大，而孔徑分佈變寬，溫度繼續升高時，二氧化硅網路發生收縮，平均孔徑變小而比表面積由於有機炭化物的完全去除沒有太大變化;微球中的微孔在熱處理過程中處于平衡狀態，分佈沒有太大變化。
  8. Shocked by the dramatic evolution of international politics and the restructuring of the regional strategic power, the situation in central - asia has been changing greatly. five countries in central - asia as a group are playing a more and more important role in the world and becoming a strategic subregion which have the potential power to influence the pattern of international politics, economy and culture. and this region will become the hot area where the world ' s main political forces contest

    冷戰結束后，在國際政治格局重大變革和地區性戰略力量重組的強烈震撼下，中亞地區形勢正在發生重大變化，戰略地位益顯突出：中亞五國正逐步作為一支集團化力量出現在國際舞臺上，已成為可能影響世界政治格局的次戰略地域；中亞地區在世界經濟體系中的地位日漸提高，將影響地緣經濟格局；世界主要文化在中亞地區的沖撞日漸加劇；中亞地區將成為世界各主要政治勢力爭奪的熱點。
  9. By a process of elimination, therefore, the three researchers were left with the conclusion that, by pushing metabolic rates up, tropical heat causes more mutation and thus more speciation

    因此，三位研究人員得到如下結論：由於代謝速度的提升，熱帶地區的熱量引起更多的突變，也因此形成更多的物種。
