高明元 단국대학교 1967 論文集 Vol.1 No.-
본 연구에서는 불완전 기체를 고전통계역학의 입장에서 취급하였다. 즉 클러스터 적분정리를 새로운 방법으로 유도하고 이것을 이용하여 몇 가지 열역학적함수를 고찰하였지만, 분자간의 상호작용은 원래 양자론의 범주에 속하며 따라서 불완전 기체의 더 심오하고 엄밀한 연구에는 양자통계역학의 입장에서 고찰할 필요가 있다.

When the electric field, F acts on a hydrogen atoms in Ζ-direction, the interaction energy between hydrogen atoms and the applied electric field may be represented by eFΖ=eFrcosθ=eF3α_0/2ρcosθ Suppose that hydrogen atoms are in the states of principle quantum 3. In the states, hydrogen atoms are degenerated, having nine wave functions of same energy. It was attempted to evaluate the first-order perturbation energies using degenerated perturbation theory, putting λΗ^(1)=eFΖ The calcuated energies are as follows. W′=0, W′=±95.26α_0eF, W′=±13.59α_0eF These values indicate that energy levels split into five.

高明元 단국대학교 1974 論文集 Vol.8 No.-
The purpose of this paper is to elucidate the mechanism of adsorption in terms of the ideas of semi-conductivity by measuring the change of electric conductivity of metallic oxides (ex.; ZnO, MoO) due to the adsorption of a gas (ex.; CO_2, O_2, N_2, SO_2) It is well-known that the oxides of transition metals belong to n-type or p-type semi-conductors and their semi-conductive property are much influenced by the property of A adsorbed gas. In general, if A gas is adsorbed on the surface of solid, migration of electrons or polarisation of charge occurs. C. Wagner supposed that adsorbent molecules form surface electronic energy level in order to explain the relation between the electric conductivity of metallic oxides as semi-conductors and catalytic activity in the decomposition of nitrous oxide. T. Wolkenstein developed Wagner's theory. Generally, positively charged adsorption or negatively Charged adsorption on n-type semi-conductors increases or decreases electric conductivity respectively, It is contrary in the case of P-type conductors. Films of the metallic oxides were prepared on glass plate under 10^-4 Torr and their resistance were measured at various temperatures. Thereafter the resistance of the films adsorbed by gas were measured at 100℃. The Change of electric conductivity was investigated by means of the experimental data and the mechanism of the given adsorption was supposed from the semi-conductive point of view. As te result, a considerable part of gaseous molecules is considered to be adsorbed in the form of ions.

This study is to determine the mean activity coefficient hydrogen chloride in the mixed solvent of water and methanol by measuring the electromotive force of the following cell; H_2|P_t(1atm)|HCl in the mixture of water and methanol|AgCl|Ag the calculated values of the activity coefficient is obtained from me extented Debye-Hu¨ckel equation. The observed values of the mean activity coefficient is compared with the calculated values. The origin that causes the difference between the observed values and the calculated values is investigated.

Sprue와 Wax Pattern의 각도 및 방향에 따른 주조성 연구
고명원,최운재,정희선 대한치과기공학회 2004 대한치과기공학회지 Vol.26 No.1
This study obtained the following consequences, as a result of the comparative analysis for thecastability depending on an angle of the sprue and wax pattern in case of manufacturing dentalprostheses, for the castability depending on direction, and for the castablility of sprue, whichattached the reserve to each different 3.5mm roll wax(sprue wax) and to 2.5mm sprue wax. 1. As a result of the comparative analysis for the castability depending on an angle of the sprueand wax pattern, the best castability was shown when the angle of the sprue and wax pattern is180°∆(straight line), and the lowest castability was shown in 45°∆, which was curved most, andthere was no statistical significance. 2. As a result of the comparative analysis for the castability of an angle depending on direction,the best castability was shown in the farthest side from the direction of centrifugal casting, and thelowest castability was shown in the same side as the direction of centrifugal casting, and therewas no statistical significance. 3. Given comparing the castability depending on the pattern of sprue, the better castability wasshown in 135°∆and 180°∆when using 3.5mm roll wax(sprue wax), compared to attaching thereserve to 2.5mm sprue wax.

This study wa attempted to extract the Potash-Ammonia Fertilyzer in most satisfactory yield from the Uncalcinecl Domestic Alunite ore applying an optimal reaction conditions (Ammonia water concentration and applicable reaction pressure, etc.), it was found that almost all amount of $K_2SO_4$ was extracted in the forms of $K_2SO_4·(NH_4)_2SO_4$</TX>mixture under such conditions. The experimental data to note are as follows: 1. The optimal pressure applied to the reaction was 600 to 700 Psig. 2. The optimal concentration of Ammonia water was 7 Mol/L. 3. The reaction time needed was 3 hours. 4. The extraction rate and degree were not at variance with sorts and occurrences of Alunite ore.

活性白土에 關한 硏究(제II報) 酸性白土의 構造 推定에 關하여
손선관,고명원,Son, Sun-Kwan,Ko, Myoung-Won 대한화학회 1970 대한화학회지 Vol.14 No.4
Composition of Acid Clay, the raw material for activated clay manufacturing, was investigated to develop useful data in deciding activation condition. Speculations on components and structure of activated clay were also made in order to see how included components of raw materials change during activation process. And a study was made on relations between structure of activated its adsorptivity. For this research, theremogravimetric analysis, X-ray differaction analysis and calculation of adsorptive index were carried out.
