  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

    直流電沉時,基質金屬的沉連續進行,粒子在電極表面不間斷嵌入鍍層;單脈沖電沉由於脈沖間歇的存在使得具有較大的粒子會脫附,重新回到中;採用周期換向脈沖時,反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附,同時,反向脈沖電流對基質金屬的解作用,也會促進粒子的脫附,因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加,三種鍍層的晶粒都明顯細化,說明al _ 2o _ 3的存在阻止了晶粒的長大,提高了電沉過程中晶核的形成速率。
