本地连接中“修复”功能实用两例

随着越来越多的朋友进入"无线一派"这个大家庭,无线网络的安全也就倍受大家关注了.相对而言,无线比有线网络更难保护,因为有线网络的固定物理访问点数量有限,而无线网络中信号能够达到的任何一点都可能被使用.     

Prediction of Kinematic Viscosities for Binary and Ternary Liquid Mixtures with an ASOG-VISCO Group Contribution Method

The kinematic viscosities for 273 binary and 11 ternary systems were predicted with a new model (ASOG-VISCO) developed by combining the ASOG group contribution method and Eyrings theory of absolute reaction rates. The ASOG-VISCO group pair parameters were determined from literature kinematic viscosity data for group pairs of CH₂, ArCH, CyCH, OH, H₂O, CO, COO, CCl₃, and CCl₄ in the temperature range of 283.15 to 333.15 K. The overall average deviations between experimental and predicted kinematic viscosities for the binary and ternary systems were 4.15 and 5.03%, respectively. The predicted results using ASOG-VISCO were better than those determined with the UNIFAC-VISCO group contribution method.Paper presented at the Sixteenth European Conference on Thermophysical Properties, September 1–4, 2002, London, United Kingdom.
