Through Raman mapping measurement,the thickness of the induced conducting layer of PVDF is determined to be about 7 μm.
通过测量KrF准分子激光辐照前后PVDF的拉曼光谱和红外光谱,分析了PVDF经激光辐照后表面电导率大幅度提高的机理;采用逐点扫描拉曼成像技术,确定出激光辐照后PVDF的导电层厚度约为7。
This paper researches the basic algorithms of Computer Graphics including the algorithm for implementing Boolean operation between regions and the pixel-level algorithm for generating parametric curves by dividing the segments.
随着光栅显示器的广泛使用，逐点算法已成为目前图形学基础算法中的一个研究热点。
The unit layer quantitative interpretation method adopting point-by-point spectrum striping is introduced.
本文分析了目前常用的γ能谱测井平均含量法、传统剥谱法对不饱和混合矿层(铀、钍、钾元素的含量在矿层中分布不均匀)的定量解释存在的原理缺陷;提出了利用γ能谱测井分离铀、钍、钾元素的定量解释新方法—逐点剥谱的单元层定量解释法,简单讨论了该解释方法涉及的形态系数、换算系数和单元层饱和度的确定,以及反形态系数的计算问题。
