A reliable knowledge of the activity coefficients at infinite dilution is of particular importance for the synthesis, design, and optimization of separation processes, since the largest separation effort is required to remove the last traces of impurities. The GLC (Gas-Liquid Chromatography) technique was chosen owing to the possibility of a fast and reliable determination of γ∞ values To sum up, the data in Table 1 and eq 12 are considered to be widely applicable and reliable. According (to): 按照、根据、从……来看 (根据……方法)： This paper analyzes the resistivity curves at different magnetic fields according to the above approach. The necessary critical properties and molar volumes are collected/estimated according to the methods recommended by Reid et al. (根据……结论) According to the regression lines for Tp and magnetic field (B) in Figure 3d, it can be seen that there is a very simple linear relationship between the two variables. (The symbol ○ refers to measured data, while the symbols + stand for modeled results.) According to the results, crystallization operating with higher temperatures is more advisable for EGPA preparation. (根据……定理) According to the Gibbs-Helmholtz equation, the value for the partial molar enthalpy at infinite dilution can directly be obtained from the slope of this straight line. 14. 如何在科技写作中提出问题？ 一般用特定词组表达问题，很少使用反问、疑问句。 1. 用It is necessary to. . .的句型，如 “Is the result correct?”→→ It is necessary to examine (investigate/test/determine) whether those results are correct. 有必要检查一下这些实验结果是否正确 How much fuel will be consumed? →→ It is necessary to determine how much fuel will be consumed. 有必要确定需要消耗多少燃料 2. 用as to引出问题，如 Which data is correct?→→ A decision should be made as to which data is correct. 我们应当决定究竟哪一个数据是正确的。 How can the industrial pollution be controlled? →→ Research is going on as to how the industrial pollution can be controlled. 人们正在研究如何控制工业污染。 3. 用“It is doubtful /not clear/ unknown how…..”引出问题，如： How accurate are these experimental results
