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。

Abstract」By the approaches of index and explanation of cause and effect,with the statistics in all kinds of yearbooks edited by the authorities ,in comparisonwith some scholars'same studies about other countries or areas ,this article analysesthe impacts of modernization on the evolution of litigation rates in China,1978—2000,and tests the theoretic hypothesis about the relations between social developmentand evolution of litigation established by some foreign scholars.

内容提要」本文运用指标的方法和因果解释的方法，针对国外学者提出的有关社会发展和诉讼率变迁的关系的理论假设，参照国外学者对其他国家和地区这种关系的经验研究，利用政府出版的各种年鉴中的统计资料，分析了中国大陆1978—2000年间现代化发展对民事经济诉讼率变迁的影响。

It is shown that the M×N ChG beams in turbulent undergo three stages of evolution with increasing propagation distance,and turbulence accelerates the evolution of three stages.The turbulence results in a spreading and degradation of the maximum intensity in the far field.But β-parameter decreases with increasing beam numbers M,separate distances xd and beam parameter δ.And there exists optimal values of xd and δ,and SR of the corresponding M×N ChG beams reaches its maximum.

研究表明：在湍流大气中，双曲余弦高斯列阵光束的传输将经历三个阶段的变化，并且湍流使得光束传输经历三阶段的进程加快；湍流导致双曲余弦高斯列阵光束扩展、最大峰值光强下降，但是，β参量随光束数目M、相邻子光束间距xd和光束参量δ的增加而减少，即光束扩展受湍流的影响减小；并且，存在最佳xd和δ值使得Strehl比取得极大值。
