| 1. | Both spherical and regular crystalline forms are relatively rare .
球形的和规则的球晶形成相对来说很稀少。 |
| 2. | Study on the spherulites of polypropylene
聚丙烯球晶的研究 |
| 3. | The lamellae with edge - on and the flat - on orientation alternated to form the banded spherulites
利用原子力显微镜原位观察了环带球晶界面的片晶生长。 |
| 4. | The crystals of polypropylene were changed which induced by adding montmorillonite and p crystal of polypropylene was found in ppmn
蒙脱土的加入诱导pp晶型发生转变，生成了聚丙烯型球晶。 |
| 5. | And the spherulite growth rate of phbv is studied and the factors , which influence the growth rate and the formula of spherulite growth rate , were discussed
并通过对phbv球晶生长速率的测定，对结。晶生长的速度方程及影响因素做出修正。 |
| 6. | The lamellae in different directions could join and stop growing by each other at the interface of spherulites , which lead the formation of defects
在球晶的edge - on片晶生长前沿相遇时，形成片晶束。也有的片晶在互相接触后停止生长，导致缺陷增多。 |
| 7. | Dsc and x - ray diffraction results show that after pan - milling , the crystallinity and the size of micro crystals of pa6 decrease . melting point increases and crystallization temperature decreases
表现为结晶度降低，微晶尺寸减小；熔融温度降低，结晶温度升高；球晶尺寸减小。 |
| 8. | On the surface of phbv spherulite , some concentric ring like patterns will occur . based on the procedure of the formation of ring - like patterns , the possible mechanism is given
在球晶的表面出现有同心圆环状条纹，经实验验证为表面的不平整所导致，形成机理主要可能是结晶过程中的体积收缩。 |
| 9. | From the pom photos of polypropylene sp herical crystal , we could see that the polypropylene spherical crystal were diminished obviously , which is one of the two reasons that toughness of ppmn was improved
Pom照片表明， ppmn中pp球晶明显细化，这与聚丙烯晶型的形成同为ppmn韧性提高的原因。 |
| 10. | The surface of the pcl / pvc banded spherulites presented to be concentric periodic ups and downs . the period of the bands corresponded to the extinction rings under the polarized optical microscopy observation
Pcl环带球晶的表面由周期性高低起伏的环状结构组成，其凸凹起伏的环带与球晶在偏光显微镜下的明暗交替相对应。 |
