  1. A method to calculate quantitatively the adsorption volume or adsorption space of per mass of adsorbent derived from both the adsorbed molecule volume and the maximum adsorbance of a solute in an adsorption isotherm under a given experimential condition is presented firstly for a solid / liquid adsorption system of the solute in a dilute aqueous solution. this method is suitable for not only mono - layer adsorption, but also mani - layer adsorption and micelle adsorpion of surfactant constructed by hydrophile and lipophile groups. therefore, the surface concentration of the adsorbate, cs, deduced from the adsorption volume is possessed of the meaning of true concentration, and the value of the patition coefficient of the adsorbate between solid and liquid phass, p, attained by the cs and the c, solution concentration of the adsorbate, can be accurate. the foregoing a set of calculations are presented for the solid - liquid adsorption systems consisted of the wool fiber and separately dodecyltrimethyl - ammonium bromide ( dtab ) and hexadecyltrimethyl - ammonium bromide ( ctab ) in this paper. this provides a strong basis for adsorption thermodynamic investigation of adsorbate

    對稀溶液中溶質的固/液吸附體系,首次提出了根據吸附分子體積和實驗條件下吸附等溫線中的最大吸附量計算單位質量吸附劑的吸附體積或吸附空間的方法.此法適用於單層吸附,也適用於多層吸附和具有親水親油結構的表面活性劑分子的膠團吸附.由此,吸附質的表面相濃度cs具有真實濃度的含義,相應地,計算得到的溶質的固/液分配系數p就有了準確值.分別計算由溴代十二烷基三甲銨( dtab )和溴代十六烷基三甲銨( ctab )與羊毛纖維構成的液/固體系分配系數等,為溶質吸附的熱力學研究奠定了基礎
  2. The desorption experiments in the same ph of solutions as adsorption experiments show that the desorption coefficient is bigger than the adsorption coefficient, so the adsorption of neptunium on silica gel in nitric acid belongs to irreversible process

    用239np溶液進行上述實驗后,又用239np與237np的混合溶液或237np溶液進行了上述部分實驗以比較微克量的237np和示蹤量的239np在硅膠上的吸附行為。
  3. Based on the analysis of gas - solid multiphase catalytic reaction, the chemical reaction model is established. when the reaction is controlled by the chemical dynamic, the reaction rate is introduced by consideration of the adsorption and desorption effects. when the reaction is controlled by mass transfer, the diffusion coefficient is established which can present the flow rate increases in small reynolds domain ; for the internal diffusion, the internal diffusion coefficient is derived, and then the internal diffusion is coupled with chemical reaction to represent the phenomenon that the diffusion and the chemical reaction occur cocurrently

    本文在考慮催化轉化器載體內發生的傳熱傳質現象的基礎上,建立了催化轉化器的一維單孔道和三維多孔道傳熱傳質模型;在分析載體內以氣-固多相催化反應為特點的工作機理的基礎上,建立了催化轉化器的化學反應模型:當催化轉化處于化學動力學控制區時,引入了考慮吸附、表面反應和脫附的表面化學反應速率公式,當催化轉化處于質量輸運控制區時,引入了決定外擴散能力的擴散系數公式和和決定內擴散速率的內擴散系數公式,並與化學反應速率相耦合,得出由擴散過程決定的化學反應速率公式。
  4. Semiconductor materials was laid on the base, and the corresponding electrode was lead to. the semiconductor material has selective adsorption to the gas that changes the electronic concentration which also raises hall coefficient, corresponding changes the export of hall electromotive force, so the gas sensors which is based on hall effect was made

    當我們把半導體材料塗敷到基片上,並引出相應的電極,由於氣敏材料對個別氣體有選擇的吸附特性從而改變了材料中的電子濃度,也就引起了霍耳系數的相應變化,輸出的霍耳電動勢也跟著變化,就製成了基於霍耳效應的氣敏傳感器。
  5. Increasing ph of water samples induces partitioning of metals to solid phases and hence transport of metals with suspended sediments. 3. increase in concentration of sediment promotes adsorption for trace metals onto solid - phase in the estuary, but has little influence on partitioning coefficient for trace metals

    水體懸浮泥沙濃度的增大將普遍提高體系中微量金屬在固相中的吸附,但對微量金屬的固-液分配系數k _ d (為金屬在泥沙固相中的質量濃度與其在溶液相中的體積濃度之比值)的影響並不顯著。
  6. Its density, water adsorption, coefficient of heat conducting and the coefficient of steam pervasion are all lower than those of other board heat preservasion materials

    其密度、吸水率、導熱系數及蒸汽透系數等方面均低於其它類型的板狀保溫材料。
  7. The semiconductor material has selective adsorption to the gas that changes the electronic concentration which also raises hail coefficient corresponding changes in the export of hall electromotive force

    這種新型傳感器不僅可以根據需要輸出幾毫伏至幾十毫伏甚至幾百毫伏的直流電壓,而且具有其它半導體傳感器所沒有的優點無需另外加熱。
