integral principle meaning in Chinese

积分原理

In this context , the nlo properties of three kinds of essa ultrathin films are investigated systematically in terms of experiment and theory . the main contents are list in the following : based on the traditional z - scan theory and the huygens - fresnel ( h - f ) diffraction integral principle , we present a double - sided film z - scan theory that is suitable to characterize the nlo properties of the double - sided nonlinear mediums
本论文从实验和理论上系统地研究了三类静电自组装超薄膜的光学非线性,主要研究内容如下:在已有的z - scan理论基础之上,基于惠更斯-菲涅耳衍射积分原理推导出了适合于表征双面非线性介质光学非线性的双面膜z - scan理论。
