Spherulitic structure and mechanical properties in tension were analyzed, and stress cracking resistant properties were also tested.

分析了其球晶结构和拉伸力学性质并用扫描电镜观察断口形态，并与最终测得的耐环境应力开裂时间进行比较。

Hoffman-Lauritzen theory was used to analyze spherulitic growth kinetics and the free energy of the folding surface was derived.

由此可见，PEG链段对胶束的影响越小，PCL嵌段的影响越大，越趋向于形成片状晶体结构。

In application of high-strength spherulitic cast iron to thin-walled

白口和反白口缺陷是球铁件转向节的常见缺陷。2。

In previous studies, only spherulitic structures of PVDF membranes prepared by PVDF/single diluent systems via solid-liquid phase separation were obtained. The PVDF membranes with spherulitic structures always present poor mechanical properties, dense skin layers and wide pore size distribution.

在以往的研究中，PVDF微孔膜大多数选用的是单一稀释剂，通过发生固—液相分离制备的，所得到的膜结构都是球晶状结构，具备这种结构的膜往往存在膜的力学强度差、皮层致密和孔径分布宽等缺点。

The result shows that for both PCL homopolymers and PCL-b-PEG block copolymers, the spherulitic linear growth rate first increases with molecular weight and reaches a maximum, then decreases as molecular weight increases. Crystallization temperature has greater influence on the spherulitic growth rate of polymers with higher molecular weight.

当自由PEG在水中的占有面积S_o与单根PEG链段所占有的表面积S的比值S_o／S的值接近或小于3时，PEG链段对胶束形状的影响较小，PCL嵌段的影响占主导地位，易形成片状胶束；当S_o／S的值在3-10之间时，随着PCL嵌段分子量的增加，PCL-b-PEG嵌段共聚物在水溶液中自组装形成类似球状、棒状和蠕虫状胶束，是PEG与PCL嵌段共同的作用的结果；当S_o／S的值大于10时，易形成球状胶束。
