It is proposed that this project continue its research on the theoretical study of transport and other processes in metals and alloys. Five specific projects will be investigated. 1. They will continue their investigation of transport in random substitutional alloys. They will concentrate on understanding the dc electrical conductivity and thermopower in these materials. They will also investigate other transport phenomena in random and disordered alloys. 2. They will study the relationships between the theory of transport in random alloys (i.e. the theory that they are using for their calculations) and theory of so-called "weak localization." They will see if it is possible to merge these two theories. 3. They will study the phenomena of resistivity saturation in which there is a maximum possible resistivity in a metal or alloy (the Mott theory). 4. They will carry out calculations on the electronic properties of a model of an amorphous alloy (metallic glass). 5. They will complete their theoretical investigation of radio-frequency-size effect in the metal cadmium. They plan to carry out extensive calculations on the Illinois supercomputer.

建议该项目继续研究 对金属中的迁移和其它过程的理论研究 和合金。 将研究五个具体项目。 1. 他们将继续调查运输， 无规替代合金 他们将集中精力 了解直流电导率和热电 这些材料。 他们还将调查其他交通工具 随机和无序合金中的现象。 2. 他们将研究的理论之间的关系， 随机合金中的输运（即他们使用的理论 他们的计算）和所谓的“弱”理论 本地化“他们将看看是否有可能将这些 两个理论 3. 他们将研究电阻率饱和现象 其中在金属中存在最大可能电阻率，或者 莫特理论（Mott Theory） 4. 他们将在电子计算机上进行计算， 非晶合金（金属玻璃）模型的性质。 5. 他们将完成他们的理论研究 金属镉的射频尺寸效应。 他们计划对伊利诺斯号进行广泛的计算 超级计算机
