| 摘 要： | 根据沸点计误差公式,ε≡x_0-x/x=K-1/1+r(r+a)(1)研究设计了能够在r=0的拟静态循环态操作三种新型沸点仪。在稀浓度区,从不同角度进行检证,以期使方法和仪器得以完善。拟静态循环法的原理静态法和双循环法在浓度分布上的差别在于,后者有汽相回流(r>0)从而产生三个浓度区间,使配制浓度x_0代替平衡浓度x有(1)式所示的误差。仅当循环控制在r=0的状态,与静态法等价,称之为拟静态循环态,此时的误差为

| Abstract: | Based on the error equation of ebulliometry~1]ε≡x_0-x/x=(k-1)/1+r(r+a) (1) three type of newly developed ebulliometers, which can be used at r=0 state, are presented. Those ebulliometers were tested by different methods for the measure- ment of infinite activity coefficient γ~∞. |
