The dielectrie constants of toluene, carbon bisulphide, normal pentane, normal hexane, ethyl ether and iso-amyl alcohol were measured by a capacity bridge using a specially constructed liquid condenser at both 30° and 75℃ (22.4℃ only for the last liquid), for frequencies of 600,1000 and 2000 cycles per sec. and under pressures from 1 up to 12,000 kg/cm2. For the first four liquids, the dielectric constant is practically independent of the frequencies

作者用一电容桥及一特制之液体蓄电器以量甲苯,二硫化碳,正戊烷,正己烷,乙醚,及异戊醇之比电容。所用温度为摄氏三十及七十五度(异戊醇之温度仅为二十二度四),频率为每秒六百,一千及二千周,压力自一气压高至一万二千气压。前四液之比电容几与所用频率无关。(ε-1)/(ε+2)·1/d,(ε-1)/d及(ε~(1/2))-1/d三式中以第一式最近一常数,然压力渐增第一式之值恒随之而渐减,至一万二千气压时(在甲苯为九千五百气压),其减少约数在甲苯及二硫化碳为百分之三,在乙醚为百分之八,在异戊醇为百分之十九,显随电矩之增加而增加,至其原因篇中亦略加说明。 篇中图表惠蒙同事朱福炘先生代为抄绘,附誌谢忱。

The thermodynamic functions of an ideal subetance represented by van der Waals equation are obtained with the help of the condition that these functions reduce to those of a perfect gas in the limiting case of vanisning prassure. The volumes of the liquid state and gas state in coexistence as determined by Maxwell's rule of equal areas are expressed in a parametrie form. The nature of the dependence of the constants a and b on the chemical composition of the gas is briefly considered.

The hydrodynamic theory of viscous lubrication is studied from Navier-Stokes differential equations ,by the method of successive approximation based upon the smallness of the film thickness. It is found that the first approximation gives the Reynolds equation of viscous lubrication. To simplify the numerical nature of the solution of Reynolds equation, the equivalent variational problem is formulated. The approximate solution obtained from the variational problem involves only a very small error, but much less amount of numerical work.

本文基於Navier-Stokes氏微分方程式,研究粘滞性液体层的滑润作用;此种流体动力学的理论,乃依据液体层之薄度进行续步渐近之解法而得。本文除证明初步近似解答与Beynolds氏方程式之结果相合外,更进一步将解答Beynolds方程式的问题,代以一实际相等的变值问题。其结果非但减少计算工作,且亦正确可靠。
