The Kelvin equation for a compressible liquid in nanoconfinement is written in a form that takes into account not only Laplace's pressure, but also the oscillatory compression pressure. This leads to a simple analytical equation for pressure in nanocapillaries. The corrected equation is used to analyze properties of aqueous systems, including the oscillatory structural forces between attractive surfaces and inert surfaces, repulsive "hydration" forces between hydrophilic surfaces, and attractive "hydrophobic" forces between hydrophobic surfaces. Relative vapor pressure in a nanocapillary also is discussed.
纳米限域中可压缩液体的开尔文方程以一种不仅考虑拉普拉斯压力，还考虑振荡压缩压力的形式书写。这导致了一个关于纳米毛细管中压力的简单解析方程。修正后的方程用于分析水体系的性质，包括吸引表面与惰性表面之间的振荡结构力、亲水表面之间的排斥“水化”力以及疏水表面之间的吸引“疏水”力。还讨论了纳米毛细管中的相对蒸气压。
