利用Onsager和Kirkwood的极性液体理论，分析了现有的介电常数与压力关系的实验数据。在大多数情况下，有必要假定由分子内畸变引起的偶极矩有明显的减少，在某些情况下，这种减少可能大到足以补偿由分子间压缩引起的有效矩的增加。给出了这两个因素的定量估计，并讨论了它们对结合能和可压缩性的影响。
The Onsager and Kirkwood theories of polar liquids have been used to analyze the available experimental data on the pressure dependence of the dielectric constant. It is found necessary in most cases to assume an appreciable decrease in the dipole moment arising from intramolecular distortion which may be large enough in some cases to more than compensate for the increase in effective moment caused by intermolecular compression. Quantitative estimates of these two factors are given, and their influence on binding energy and compressibility is discussed.
