    In this paper, through many years′study on earthquake prediction, and on the basis of observational data since 1982, the mechanism and characteristics of coseismic and postseismic effect are analyzed, the space distribution, such as single well, concentration, banding and migration etc. of post seismic effect is put forward. This has indicative significance for predicting the location of aftershocks in the old seismic area and successive earthquakes in the periphery area and near the well location.

Rare Earth Elements (REEs) play an important role on understanding and studying hypergene processes.As of the chemical characteristics,input resources,migration and fractionation of REE in hypergene water,the complete process of REE′s activation and re fractionation is summarized,and the significance of REE in natural water and paleo sediments is also discussed by shale relative to deeper sea sediments.Considering the mistake found in the analytical means,it is necessary to recorrect the past wrong conclusions and to re estimate the geological significance of REE in water and evolution of lithosphere as well as other sediments.

REE是了解和研究地球表生过程的一个重要手段。通过REE的化学性质、物源和在表生水中的迁移和分配,综述了REE在表生过程水中的独特行为和再分配的全过程,同时利用表生水作用的代表产物——页岩,讨论了REE在水与古沉积物中的作用和指示意义。由于REE测试方法中存在的问题,指出了过去研究中可能错误的结论和当前重新评估REE在水和岩石圈演化中分配及其地质意义的重要性

The space Hausdoff dimension, correlation dimension and information entropy ofseismicities appeared anoma1ously in north-western Yunnan before Lijiang M7.0earthquake in February 1996- These anomalies occurred after the formation of largeearthquake preparation zone and the acceleration of energy release, which just indicates anonlinear developing process in and near the source zone before the final energy release. Itis fully agreed with the results of the fractal study before 8 large earthquakes occurred inYunnan Province and its adjacent region since l965. It is shown that the fractal anomaly ofseismicity is of important indicative significance for earthquake preparation.

The multiple anomalies of seismic wave in kinematics and dynamics observed at Eryuan and Tengchong stations, Vp/Vs ratio anomalies recorded at numerous stations in northwest Yunnan and their dynamic evolution process in time-space before the M 7 0 Lijiang earthquake on Feb 3, 1996 are discussed in this paper It is found that all the multiple mutation characters of seismic wave appeared about one year before the event; of the mutation characters the abrupt anomaly scale of Vp/Vs ratio at sigle point before the large event was 5 times of the scale of that before moderate-strong event; the abrupt anomaly scale of amplitude ratio before the large event was about 3-5 times of the scale of that before moderate strong event; the continuous time ratio of coda wave remained in low value of anomaly for about one year before the event and the time scale was about 3 times larger than that before moderate-strong event At same time, the analysis of spatial image evolution shows that a turn in the strike of anomalous area of velocity ratio in strip distribution appeared 1-3 years before the event, and the intersection area of anomalous strips with the turns is the epicenter of future large event Therefore, the abrupt in large scale of seismic wave in some time interval or the intersection area of velocity ratio anomalies with turns in strikes may be a precursor information of medium-short term before great event And also, the spatial location of mutation point has some meaning to futrue great earthquake, but in does not mean the epicenter of the great earthquake

本文论述了1996年2月3日丽江70级地震前洱源、腾冲两个地震台的多项地震波运动学和动力学异常及滇西北多台波速比异常的特征,探讨了其时空演化的动态变化过程。得出:在时间进程上,多项地震波突变特征均在震前一年左右的时间出现。其中,波速比在大震前的单点突变异常幅度为中强震的5倍之多;振幅比突变异常幅度约为中强震的3—5倍;尾波持续时间比则是在震前一年左右出现持续性的低值,时间尺度约为中强震异常时间的3倍以上。同时,在空间演化图像的分析也表明,呈条带分布的波速比异常区在震前1—3年出现走向上的转折,而异常条带转折的交汇区域即为未来大震的震中。因而指出了地震波在某一时段所呈现出的大幅度突变或波速比异常区发生的走向上转折的交汇区,可视为大震的中短期震兆信息。此外,突变点的空间位置对未来大震具有一定的指示意义,但并非是未来大震的震中
