In this paper, the stoker's method in optics is applied to the phenomena of reflection and refraction of elastic waves on boundary surface between two media. The coefficients of reflection and refraction of P-wave on liquid-liquid boundary surface and those of SH-wave on solid-solid boundary surface are calculated. In addition, it is proved that the seattering matrixes of elastic waves on solid-solid boundary surface are unitary Hermite ones.

In this paper, a set of analytic solutions to reflection and transmission is derived, which are suitable for P, SV and SH waves incidence on any possible interfaces composed of solid, liquid, gas and vaccum, such as solid-solid, solid-liquid, liquid-liquid and free interfaces etc. So the reflection and transmission equations, which were established by their boundary conditions and were regarded as no relation to each other are integrated. The difference of dynamics between converted wave and non-converted wave is illustrated with the solutions, and the conclusion is that for elastic plane waves incidence on different boundary conditions, the coefficients of reflection and transmission are the odd function of raypath parameter p for converted wave; and the even function of raypath parameter p for non-converted wave. Theoretical investigation has shown that amplitude versus angle of incidence (AVA) is comprised in reflected, transmitted and converted waves. Based on the properties of odd and even functions, no wave conversion occurs at normal incidence, and the conclusion offers a new way for the simplification of Zoeppritz equations and for the extension of AVA analysis in seismic exploration.

本文对Aki固体-固体分界面的反射和透射公式进行适当变换,使之成为一组适合不同坐标系下,固体、液体、气体和真空之间所有可能形成的分界面上,入射P、SV和SH波所形成的反射和透射公式,从而把不同边界条件的反射和透射方程统一起来,并且阐明了转换波和非转换波动力学特征的差异.指出:在不同弹性介质分界面上入射平面弹性波,转换波的反射系数和透射系数是射线参数p的奇函数;非转换波的反射系数和透射系数是射线参数p的偶函数.根据奇函数和偶函数的性质可见:垂直入射时不存在转换波.同时也为简化Zoeppricz方程,开展AVO分析打开新思路.

Solid-solid surface adsorption of Eu2O3 of amorphous A12O3 was investigated by Mossbauer Spectroscopy,X-ray diffraction analysis and a Laser Raman Spectra.

用穆斯堡尔谱学,X射线衍射和激光喇曼光谱研究了Eu_2O_3在非晶Al_2O_3上的固体—固体表面吸附。没有观察到Eu_2O_3的X射线衍射峰。随着Eu_2O_3含量的增加,同质异能移和线宽持续增加并趋近体相Eu_2O_3值。激光喇曼光谱表明Eu_2O_3含量为18.7Wt.%时,出现表征二维含铕表面氧物种998cm~(-1)和1051cm~(-1)的两个弱振动峰。当Eu_2O_3含量增加到36.5wt.%时,出现表面氧物种的1068cm~(-1)峰和Eu_2O_3的342cm~(-1)特征峰。比较了Eu_2O_3在非晶Al_2O_3和在其他载体表面的分散情况。同质异能移的变化缘于载体具有不同的电负性。研究结果表明,存在载体对分散在载体表面的Eu_2O_3结构形成的诱导效应。
