  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、擴系數與n型發區的磷相匹配, 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源,但b在硅中的固溶度大( 1000時達到5 10 ~ ( 20 ) ,擴系數小, b在硅中的雜質分佈易形成pn結中雜質的線性緩分佈,導致器件滿足高反壓的要求,隨之又出現了硼鋁塗層擴工藝和閉管擴鎵工藝,前者會引起較大的基區偏差,雜質在硅內存在突區域,導致放大系數分嚴重,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、生產效率諸方面均令人滿意。
  3. A quantitative analysis on the surface of the plate composite membranes with various polymerization tune was made on the basis of the feature absorption to ir by means of attenuated total reflection - fourier transform infrared spectroscopy. the results showed that polyamide functional layer grew thick with the polymerization time going on. this indicates that the polyamide functional layer formed on the interface cannot separate the w / o phases to stop the reaction

    利用衰減全反-傅立葉換紅外( ftir - atr )對同聚合時間的平板復合膜表面進行了特徵吸收定分析,研究發現,聚酰胺功層隨聚合時間斷增厚,這說明已形成的聚酰胺功屏障兩相而終止反應,相反由於哌嗪單體的分子遠低於納濾截留分子的范圍,很易擴穿過功層達到兩相界面,繼續與有機相單體酰氯反應。
  4. The experimental results indicate that when the air flow rate is determined, the key problem for energy saving is how to keep the indoor thermal comfort at a suitable level and reduce the difference between the internal and external temperature of the room. a formula is gained for calculating the critical values of air exchange rate. when ventilating rate is greater than the value, radiating heating is the better way for energy saving, or else, convection method in heating is more suitable

    實測還指出,當通風一定時,如何保證人體熱舒適度而減少室內外氣溫差將成為大通風房間節約採暖耗的關鍵,本文結合圍護結構傳熱機理,在對三種方式的耗狀況進行理論分析的基礎上,提出了換氣次數的節臨界值,若換氣次數高於此值,則輻供暖是較好的選擇,否則,熱器供暖是較好的方法。
  5. The change of energy in wall rock is tracked in the whole process and the amount of energy transferred to linings is also evaluated. 5 ) based on the principal of energy invariance and the energy properties of sfrc, a practical design equation that related the thickness of projecting sfrc to the energy related properties of tunnel is given in the end. this equation is then used to design a single - track railway tunnel in iii grade rock condition
