| 1. | Study on the spherulites of polypropylene 聚丙烯球晶的研究 |
| 2. | 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。 |
| 3. | The growth of lamellae at the interface of the banded spherulites was studied in situ using atomic force microscopy ( afm ) with a hot - stage 研究表明,片晶的扭转不是一个渐变的过程,而是发生在相对较窄的区域。 |
| 4. | 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。 |
| 5. | The growth speed was forced to decreased by the spatial hindrance and limitation of the crystalline chain segment during the closing up of the two spherulites 在结晶的早期,片晶在生长过程中, edge - on片晶和flat - on片晶交替取向,逐渐充满球形的空间。 |
| 6. | The lamellae with edge - on orientation in the ridges and the flat - on lamellae in the valleys of the banded spherulites were observed clearly . the twisting between the edge - on and flat - on lamellae was also observed 片晶在凹下环带区域的排列主要是flat - on取向,而凸起环带区域的片晶排列主要是edge - on取向。 |
| 7. | 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。 |
| 8. | Pcl could form banded spherulites through blending with poly ( bisphenol a - co - decane ) lamellar structures of banded spherulites of poly ( s - caprolactone ) / poly ( vinyl chloride ) ( pcl / pvc ) blends were observed using tapping mode atomic force microscopy ( afm ) 利用原子力显微镜( afm )的轻敲( tapping )模式,系统地研究了聚-己内酯聚氯乙烯共混体系形成的环带球晶表面形貌和片晶结构。 |
| 9. | Polarized optical microscopy and phase - contrast microscopy were used to observe the banded spherulites of poly ( e - caprolactone ) / poly ( vinyl chloride ) ( pcl / pvc ) blends . the ring spacing and regularity of the banded spherulites decreased with the decrease of the crystallizing temperature 本文利用偏光显微镜和相差显微镜观察了聚-己内酯聚氯乙烯形成的环带球晶,环带间距随温度的降低而减小,规整性亦随之下降。 |
| 10. | The thickness had some influence on the development of the banded spherulites : when the thickness reduced to some degree , pcl would develop chrysanthemum - like spherulites , which had no extinction rings or the maltese cross pattern under the crossed polarized optical microscopy . the results of the phase - contrast microscopy showed that growth speed of the chrysanthemum - like spherulites along the radius was not constant 发现薄膜厚度对球晶的生长有一定的影响,当共混物膜薄到一定程度时, pcl不能形成环带球晶,而是形成一种类似菊花状的晶体,在偏光显微镜下看不到环带,也没有典型球晶所特有的maltese十字消光图案。 |
