摘　　要：详细阐述了气相二氧化硅在硫酸介质中形成凝胶的落管式强度测定方法,讨论了影响凝胶强度的因素和强度标准。由于这个物理指标仅仅表征静态凝胶的特性,所受影响因素多,因而建议它的意义在于更多地用于胶体电解液配方的筛选。A fall-tube method measuring the strength of gel formed by fumed silica in sulfuric acid medium was described in detail. The factors affecting gel strength as well as the standard for gel strength were discussed. Since this physical index only expressed the static property of gel and many factors influenced gel strength, it was suggested that the significance of gel strength should be mainly in searching the formula of good colloidal electrolytes.
