9406812 Van Zytveld Technical abstract: It is proposed to measure the electronic properties of several strong-scattering liquid systems. The parameters of emphasis are the electrical resistivity and the thermoelectric power, since these can be compared rather easily with theoretical calculations, and will therefore provide a good test of theory. The systems under study include the liquid semimetallic alloys aluminum-calcium and aluminum-barium, the pure liquid metals silicon and germanium, three of the liquid heavy trivalent rare-earth metals, and the unusual "heavy Fermion system", cesium-copper, in liquid form. These studies will further the understanding of these interesting classes of liquids, and may also uncover materials of interest for thermoelectric power generation. Non-technical abstract: It is proposed to measure the electronic properties of conducting liquids: liquid metals, liquid alloys, liquid semimetals and liquid semiconductors. In each of the systems to be studied, the interaction between the conducting electrons and the liquid ions is strong, making these properties more difficult to understand theoretically. It is anticipated that these experimental studies will provide strong tests of the current theories; an evaluation of the properties for possible applications in thermoelectric power generation will also be made. ***

9406812 Van Zytveld 技术摘要：建议测量几种强散射液体系统的电子特性。 重点参数是电阻率和热电势，因为它们可以很容易地与理论计算进行比较，因此可以提供良好的理论检验。 正在研究的系统包括液态半金属合金铝钙和铝钡、纯液态金属硅和锗、三种液态重三价稀土金属，以及不寻常的“重费米子系统”——液态铯铜。 这些研究将进一步了解这些有趣的液体类别，并且还可能发现可用于热电发电的材料。 非技术摘要：建议测量导电液体的电子特性：液态金属、液态合金、液态半金属和液态半导体。 在每个要研究的系统中，导电电子和液体离子之间的相互作用很强，使得这些特性在理论上更难以理解。 预计这些实验研究将为当前理论提供强有力的检验；还将对热电发电中可能的应用特性进行评估。 ***
