考虑了两个固体表面之间的蒸汽毛细凝结问题。考虑了固体/液体/蒸汽接触线上的线张力和固体之间的表面力对冷凝的影响。在固体表面的不同几何形状中，分析了液体桥的稳定性与相对蒸汽压力、固体之间的距离及其表面化学性质的关系。主要目的是研究线张力的存在如何影响液体毛细管桥的形成，并说明从单分散球形颗粒床和表面力装置（SFA）中观察毛细凝结来估计线张力的可能方法。
The problem of capillary condensation of vapour between two solid surfaces has been considered. The effects on condensation arising from both the line tension at the solid/liquid/vapour contact line and the surface forces between the solid bodies have been taken into account. The stability of the liquid bridges in different geometries of the solid surfaces has been analysed in relation to relative vapour pressure, distance between the solid bodies and their surface chemistry. The main objective has been to investigate how the existence of line tension influences the liquid capillary bridge formation and to illustrate possible ways for the estimation of line tension from the observation of capillary condensation in beds of monodisperse spherical particles and in the surface force apparatus (SFA).
