說一下具體作者，期刊名稱，年月用你給的信息查到的是上海理工大學(xué)動(dòng)力工程學(xué)院的碩士畢業(yè)論文順便留意下郵箱

是不是上海理工大學(xué)龔智方的《電聲法膠體Zeta電位的測(cè)量》？這可是一篇碩士論文啊！購買這篇論文是要花不少錢的！

電位法誰能解釋下啊:

誰能幫我翻譯下這片文章？翻譯的好的在追加100分?。?！: Experimental Method All experiments were carried out in a high-pressure CO2 apparatus (Speed-SFE from Applied Separations) (see Figure 1) with a 300-mL extractor designed for a maximum pressure of 690 bar and a maximum temperature of 2... Experimental Method All experiments were carried out in a high-pressure CO2 apparatus (Speed-SFE from Applied Separations) (see Figure 1) with a 300-mL extractor designed for a maximum pressure of 690 bar and a maximum temperature of 250 °C. The volume of the extractor had to be reduced to 50 mL by a metallic cylinder， which tightens to the extractor wall， because as preliminary tests showed the equilibrium cell has to be completely filled with material. Otherwise， diffusion is the limiting factor and time for reaching equilibrium was too long. The extraction vessel was filled with compressed CO2 by an air-driven pump at closed outlet valves and under static conditions， which means desired pressure and temperature; the cell was incubated for 15 h， maintaining these conditions to reach equilibrium. In preliminary experiments the equilibrium time of 15 h was determined to reach equilibrium. CO2 Sampling. At equilibrium a CO2 phase sample is taken by opening the outlet valve and expanding a certain amount of CO2-substance mixture into a cooling trap filled with toluene， which has the highest solubility for the measured substances under atmospheric conditions. The pure gaseous CO2 passes a rotameter， showing the actual flow rate， and a gas flowmeter for determining the expanded CO2 amount. The content of the cooling trap was filled up with toluene to 30 mL and analyzed by a gas chromatographic method using an electron capture detector (GC-ECD). With the mass of expanded CO2 and composition of the cooling trap solubility at a certain pressure and temperature was calculated. Sampling was repeated four times at a given pressure and temperature and the standard deviation was lower than 5%. Gas Chromatographic Method. The tolueneflame retardant mixture of CO2 sampling was analyzed in a gas chromatograph (HP 5890 Serie II) with an ECD using a capillary column (type HP-1， 12 m 0.2 mm 0.2 ím). The injector temperature was held constant at 290 °C and the detector temperature at 300 °C. The oven temperature was held constant at 290 °C. Calibration with different amounts of HBCD and TBBA in toluene has been done before determining the linear range of calibration line and retention time of substances 展開
