The orientations of polyurethanes resulted in a large number of the residualorientation , the stress softing and stress hysteresis , the permanent set , the higher modulus and strength of materials .
取向的结果,导致大量的硬段残留取向、应力软化、应力滞后和高变形,以及材料的高模量和高强度。

Residual stresses and molecular orientation throughout a product provide important information about how that product will perform.
残余应力及分子取向整个产品提供了重要的资料,如何生产表演。

The preoperative level of orientation should be achieved, although a mild degree of residual sedation is acceptable.
