If restrained, shrinkage strains can cause cracking of concrete and will generally cause the deflection of structural members to increase with time.
因此当收缩变形不能自由进行时，有可能导致混凝土产生裂缝，并且裂缝的数量随着时间的增加而增多。
On the basis of measurement of time-dependent auto-shrinkage strains and elastic modulus of concretes, the time-dependent auto-shrinkage stresses may be calculated.
通过对混凝土依时的自收缩应变和弹性模量测定，求得依时自收缩应力。
Strains can be introduced by differential shrinkage, uneven cooling, or nonuniform flow.
株，可引入微分收缩，冷却不均匀，或不均匀流量。
