The results indicated that both binary interactive parameters of water/isobutanol system from this work and the parameters of water/ethanol from literature can be used to precdict the liquid-liquid equilibria of water/ethanol/isobutanol. But the parameters of ethanol/isobutanol from the literature were not appropriate for the prediction. Furthermore, the model parameters from 30℃ can can be used to predict the liquid-liquid equilibria under 35 ℃. The model parameters of water/isobutanol are independent on the temperatures, so constant parameters irrelative to temperature can meet prediction accuracy. Othmer-Tobias/Bancroft equation was also used to fit the liquid-liquid data of water/ethanol/isobutanol system, but it didnt possess the performance of predicting the liquid-liquid equilibria.The partition coefficients of dipotassium glycyrrhizinat were determined in the liquid-liquid two-phase system of water/ethanol/isobutanol and corrected by experiential equation.

结果表明：由本文的二元液液相平衡实验数据关联得到的水+异丁醇体系的相互作用参数和文献上由二元气液相平衡数据关联得到的水+乙醇体系的相互作用参数都具有预测三元液液相平衡关系的能力，而文献上由二元气液相平衡数据关联得到的乙醇+异丁醇体系的相互作用参数不具有预测三元液液相平衡关系的能力；可以用从30℃三元液液相平衡数据关联回归得到的模型参数来预测35℃时的液液相平衡关系；水+异丁醇的相互作用参数与温度关系不是很密切，计算时取与温度无关的常数即能满足关联精度要求；Othmer-Tobias和Bancroft经验方程可用于水+乙醇+异丁醇两相体系的液液相平衡关系的关联计算，但这类经验方法并不具有预测能力。

Thermogravimetric analysis was extended to the measurements on vapor pressures of three n-alkanes, hexadecane, heptadecane and octadecane, on the basis of the Langmuir equation for zero-order vaporization process. The vapor pressures were calculated by two different methods, a constant-parameter one and a comparative one, from the TGA data. These results are in good agreement with the reference data calculated from the Antoine equation.

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.

因此本章会先就父子关系的冲突与矛盾做深入的探讨，小说中的父亲似有对儿子爱之深责之切的行为，其原因可能在於父亲将儿子视为所有物所致；其次，论文将引用拉冈相关理论，讨论在父权社会中，不论身分为何，只要是已受父权社会观念根深蒂固影响的人物，终生都将受其所苦，此也揭示出人生存於社会上的无奈。
