When the velocity proportion of longitudinal wave to transverse wave of a bed is distinctly different from that of another bed, the reflection factor will be changed with the variation of incident angle according to the elastic wave mechanics, which is the foundation of AVO theory.

由弹性波动力学理论可知，当一种岩层纵、横波速度与另一种岩层纵、横波速度之比明显不同时，反射系数随入射角的变化而变化。

Aformula which describes the transient process from beginning traveling waveto steadytraveling wave was deduced and the concept of initial traveling wave stagefirst was defined and its duration was given. It leads to a conclusion that reflectionfactor is a time dependent function, and variation range and reflection factor atdifferent stage were presented .Based on unified traveling wave theory andtransmission line model of reflective terminal with energy storage element , powerpolarity of initial traveling wave was analysed with both physical and mathematicalmethod.

通过理论推导得出从初始行波到稳态行波过渡过程的数学公式，统一了不同阶段的故障分量信号；定义了初始行波的概念，并指出了其持续时间的影响因素，针对末端含有储能元件系统，从物理和数学两方面剖析了初始行波的功率极性；通过分析提出反射系数是时变函数，给出了在不同暂态阶段行波反射系数的变化范围。

Based on the study of chronology and geochemistry of Cd in sediments of the Dongting lake area, we have established an ARIMA model of Cd and Cd/Ca in Quaternary and Holocene period respectively, and discussed Cd evolutionary regularity according to the fitted value and predicted value of the model The results revealed that the Cd evolution has remarkable periodicity of ecogeochemistry cycles, and is correlated with the climate change of alternative cold and warm Cd/Ca is changed with climate, from which the evolutionary history of regional ecogeochemistry can be inferred The changes of Cd and Cd/Ca are basically simultaneous, which showed that the change of Cd is mainly a natural evolution Cd in sediments will rise in the next 30 years and then tend to decrease From the regularity of ecogeochemistry indexes and global environment variation, it is concluded that the natural environment is the dominant factor affecting the Cd deposition

在对洞庭湖区沉积物钻探取样的年代学和地球化学研究基础上，分别建立第四纪和全新世时期Cd和Cd/Ca的时间序列演化ARIMA模型，并据模型的拟合值及未来预测值对区域地球化学环境中Cd的演化规律进行了探讨，结果显示区内Cd的演化有较显著的周期性--环境地球化学旋回，与气候多次冷暖的交替有关；沉积物Cd/Ca受气候环境等控制，分析该比值的变化规律可推测区域环境地球化学的演变历史；Cd和Cd/Ca两者的变化基本同步，说明该区Cd的演化主要为自然演化；未来30年内沉积层的Cd含量仍有逐渐增高的趋势，之后转为降低。从本区环境地球化学指标的时间变化规律及其与全球环境变化的相关联中说明自然条件是区域镉等元素沉积的主控因素。
