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

The feathers attached to the arms and the tail evidently possess the structures of " modern feathers ", which consisting of the central shafts ( rachis ) and parallel barbs. dromaeosaurids are unusual group of maniraptoran theropods. they share many similar or the same features with archaeopteryx or other primitive birds, such as : u - shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and " modern feathers " with rachis and barbs etc. these facts indicate not only that dromaeosaurids had developed many bird - like characters in course of the advanced maniraptorans toward birds, but also that there seemed to be the co - evolutionary trend between the feathers and the skeletal bones
