1) Analysis of oxygen in high purity metals: By using new type oxygen analytical method employing oxygen sensor and pump, the oxygen contents in high purity Ge,Bi and Sb have been determined. The analytical values were highly consistent and reliable despite the fairly low oxygen concentration in the sample.2) Thermodynamical properties of oxygen in liquid binaly alloys: Activity coefficients of oxygen in Ni-S and Co-S melts were determined by using a modified coulometic titration technique. The activity coefficients of oxygen in both melts are rapidly increased with increasing the sulfir compositions.3) Thermodynamic study of liquid binary and temary alloys including In or Ga: By the EMF method using stabilized zirconia solid electrolyte, indium or gallium activities in Ga-Sb-In,Ga-Sb-Bi,In-Bi-TI and In-Pb-Sb temary alloys were determined. The other thennodynamic properties were calculated based on Gibbs-Duhern equation and modified calculation method for temary alloys from the data of each constituent binary alloys.4) Thermodynamic study of compound semiconducten materials: The activities of gallium in the whole composition range of GaAs-InAs solid solutions coexisting with arsenic poor temary liquid phases. Composition dependence of the activity can be explained qualitatively in terms of the phase relation based on the model calculation.5) Ion exchange reaction of beta-alumina and Ag or Go activity measurement in liquid Ag or Ga binary alloys: Ag^+ or Ga^+-beta-alumina solid electrolyte was prepared-by ton-exchange reaction of Na-beta-alumina in AgNO_3 or Ga- GaCl_2 melts. The EMF of following cell was measured and the activities of Ga in liquid Ga-Sb alloys were determined. The same experiments for Ag-Pb alloy by using Ag^+-beta-alumina solid electrolyte was tried, however the reliable data could not obtained because solid electrolyte was broken during EMF measurements.

1)高纯金属中氧的分析：采用新型氧分析方法，采用氧传感器和氧泵，测定了高纯锗、铋、锑中的氧含量。2）二元合金中氧的热力学性质：用改进的库仑滴定法测定了Ni-S和Co-S熔体中氧的活度系数。含In、Ga二元和三元合金的热力学研究：用稳定氧化锆固体电解质电动势法测定了Ga-Sb-In、Ga-Sb-Bi、In-Bi-Ti和In-Pb-Sb三元合金中In、Ga的活度。根据三元合金的Gibbs-Duhern方程和改进的三元合金热力学计算方法，计算了各组分二元合金的热力学性质。4）复合烧结材料的热力学研究：Ga As-InAs固溶体与贫砷三元液相共存的整个组分范围内Ga的活度。（5）β-Al_2O_3的离子交换反应及Ag或Ga二元合金中Ag或Go活度的测量：利用Na-β-Al_2O_3在AgNO_3或Ga-GaCl_2熔体中的离子交换反应，制备了Ag^+或Ga^+-β-Al_2O_3固体电解质。测量了随动电池的电动势，测定了液态镓锑合金中镓的活度。用Ag^+-β-Al_2O_3固体电解质对Ag-Pb合金进行了同样的实验，但由于固体电解质在电动势测量过程中破裂，无法获得可靠的数据。
