摘要
用广角激光散射仪考察了带有同心圆消光环的聚乙烯球晶的光散射图形,用有效偶极矩模型,结合傅里叶变换及光栅衍射原理,分析了散射图形的成因,进一步探讨了晶片的扭曲现象,理论分析与实验结果相一致.
In this paper, the light scattering patterns of polyethylene spherulitea with concentric-circle extinction are examined by wide-angle laser scattering instrument. Based on the model of effective dipole moment and by moans of Fourier transform and diffraction grating principle, the causes of pattern formation are analysed and the twisted phenomena of lamellae are further discussed. The theoretical analysis is in agreement with the experimental result.
