旋间松弛作用 spin-spin relaxation
平滑肌松弛作用 Smooth muscle relaxation
内皮细胞松弛因子作用 endothelium-derived relaxing factor ; EDRF
这样使得方向性停止产生而松弛作用开始增加。
围绕障碍物流动使融化前部的速度下降并产生较高的局部粘性而减少松弛作用。
Flow around an obstruction causes a decrease in melt front speed and leads to high local viscosity and reduced relaxation.
较高的融化和成型温度：融化粘性较低，更容易填充，较大松弛作用促成方向性减少。
Higher melt and mold temperatures: lower melt viscosity, easier filling, and greater relaxation favor reduced orientation.
