Au. the influence of several variables such as gold and cosolvent concentrations, shaking times, the ratio of tdmba and gold on the extraction of gold and the water concentration of the organic phase were studied. while the cosolvent ratio is more than 10 %, in the tdmba system, gold was extracted completely. the gold extraction mechanism was discussed on the bases of water concentrations of organic phases and infrared spectrum. it was found that the aggregation ratio of tdmba and au
等因素對萃取率的影響，並研究了有機相的連續萃取有機相金含量與水含量的關系。結果表明，助溶劑體積比10 %以上時，十四烷基二甲基芐基氯化銨對金具有萃取能力強，平衡時間短的特點。季銨鹽陽離子與au cn -
Thereupon, in the 3rd chapter, the characteristics of the ecological systems are discussed and the necessity of aggregation is proposed, then, the method of choosing macro - variables is discussed, and the aggregation method for the systems of ordinary differential equation is proposed. in the 4th and 5th two examples : the model of single population and the model of two populations in different environment are discussed, the method which have proposed in 3rd chapter is implemented in the two examples
同時在第四章和第五章中分別介紹生態系統中的兩種情況：單物種的發展模型和兩物種在不同環境中競爭的模型，分別介紹了對這兩種模型建立過程，並且應用第3章中介紹的方法對上述兩種模型進行聚合。然後，對聚合后的聚合模型進行分析，得到聚合模型的穩定狀態。
