By model 4 (letting both PEO and POM well crystallize) and model 5 (decreasing temperature at a rate of 10°C/min), when PEO content is 5%, the blend forms amorphous PEO existing among POM lamellae. When PEO content is 10%, the blend forms interfibrillar segregation crystalline structure.

在所有降温模式的共混物中，当PEO含量为5％，降温模式4时共混物的综合力学性能最优，原因是此时形成了无定形PEO存在于POM球晶微纤晶间的结晶结构，且POM的结晶度最大。7。

There exists isomorphous replacement in the rutile structure, and the most prominent feature is the average content of oxides, being 1.22%, 0.39%, 0.35% and 0.22% for V 2O 5, Fe 2O 3, ZnO and CuO respectively. They substitute Ti 4+ in octahedra. The valence of V is 5, and its polyhedron is trigonal bipyramid, which causes the lattice distortion, breaks the raw octahedron symmetry into square bipyramid, and produces the microstrains in the structure.

天然含钒金红石平均含V2O5可达1.22％，Fe2O30.39％，ZnO0.35％，CuO0.22％，这些金属离子可替代八面体中Ti^4 。V以5价形式存在，配位多面体呈三方双锥，其在晶格内部对Ti的替代导致晶格畸变，打破了配位多面体原有的八面体对称而呈四方双锥的几何形态，并产生结构微应力。

PCL is not crystallizable when its content is lower than 50 wt% in theuncured novolac/PCL blends, whereas, after cured with 15 wt% HMTA, PCL is stillcrystallizable even the content of PCL is 30 wt%.

实验结果表明在尿素及硝酸铈的混合溶液中分别加入一元羧酸硬脂酸，二元羧酸酒石酸和三元羧酸柠檬酸时，一元羧酸硬脂酸在混合溶液中只起表面活性剂的作用，其产物为斜方晶系的单晶Ce2O(CO3)2.H2O微粉，且表面活性剂硬脂酸的加入使得晶体的晶化程度明显提高；而二元羧酸酒石酸与三元羧酸柠檬酸在均相反应中则起螯合剂的作用，分别与Ce3+形成螯合物酒石酸铈和柠檬酸铈，这些结果的造成是由于其反应机理的不同所导致的。
