The proposal covers three areas of exprimental physics. The first is critical and tricritical phenomena in water-surfactant- oil systems, and the relationship of these systems to the theory of critical phenomena. The second is spinodal decomposition in mixtures of nitroethane and 3-methylpentane, with particular attention to the effect of finite quench rates. The third is the use of silica gels. grown by aggregation of colloidal silica particles, to study random field effects in binary fluid mixtures, as well as diffusion of spheres in such media.

该提案涵盖了实验物理的三个领域。首先是水-表面活性剂-油体系中的临界现象和三临界现象，以及这些体系与临界现象理论的关系。第二种是在硝基乙烷和3-甲基戊烷的混合物中分解，特别注意有限淬火速率的影响。第三是硅胶的使用。由胶体二氧化硅颗粒聚集而成，研究二元流体混合物中的随机场效应，以及球体在这种介质中的扩散。
