隐伏铜镍矿异常灰色关联滤波圈定法

在新的铜镍矿异常圈定方法的研究中，我们把灰色系统理论与地质、物探、化探方法相结合，提出了以已知矿床上建立的参考数列系为灰色子波，对研究区的比较数列系进行关联度扫描，从中圈定关联度异常，预测矿床赋存部位的灰色关联滤波法．该方法在新疆哈密研究区作了隐伏铜镍矿床预测试验，在找矿信息的采集中，选取了地质、物探、化探标志１３个．预测实践表明，关联度异常的展布与铜镍矿床的位置相对应．根据研制的方法设计的ＺＫＹ１孔，在离地表１１０～１９０ｍ，钻遇５０多米铜镍矿，证实了该方法适用于大比例尺隐伏矿床预测．

Application of uncertainty analysis to groundwater pollution modeling

Prediction and evaluation of pollution of the subsurface environment and planning remedial actions at existing sites may be useful for siting and designing new land-based waste treatment or disposal facilities. Most models used to make such predictions assume that the system behaves deterministically. A variety of factors, however, introduce uncertainty into the model predictions. The factors include model and pollution transport parameters and geometric uncertainty. The Monte Carlo technique is applied to evaluate the uncertainty, as illustrated by applying three analytical groundwater pollution transport models. The uncertainty analysis provides estimates of statistical reliability in model outputs of pollution concentration and arrival time. Examples are provided that demonstrate: (a) confidence limits around predicted values of concentration and arrival time can be obtained, (b) the selection of probability distributions for input parameters affects the output variables, and (c) the probability distribution of the output variables can be different from that of the input variables, even when all input parameters have the same probability distribution

On the mechanical behaviour of lateral filter paper drains

Summary This note deals with the mechanical behaviour of lateral filter paper drains, used in triaxial testing in the laboratory. It has been found that the maximum influence of the filter paper drain on the measured deviator stress coincides with the development of folds during axial straining. Subsequent reuse of the same filter paper drain caused a significant drop of about 70% in the maximum value of the influence.
