(1) The shrinkage of cementitious material is controlled by capillary tension, disjoining pressure, surface tension and removal of interlayer water.

(2) Collapse of lumber is thought to be caused by capillary tension in those cell lumina that are fully saturated and by compressive stresses in the inner core that exceed the compressive strength.

(3) The heat pipe with multilayer sectional silk screen structure has gradient pore change, greater capillary tension, lower reflow resistance and raised heat pipe performance.

(4) In this paper, a theoretical model is used to analyze shrinkage behavior, which is based on micro pore structure model and capillary tension theory.

(5) The long-term existing theory of wood collapse which was thought to be caused by "negative pressure" resulted from capillary tension in the water capillaries was called in question.
