查询词典 classification statistic

Firstly, variables which were acquired for the above two kinds of classification system were obtained from field and laboratory investigation of the core samples as well as test of supersonic waves in drilling holes. Secondly, distribution functions and parameters of all variables are determined using statistic method. Thirdly, 20000 RMR values or BQ values and cumulative distribution function of these RMR or BQ values have been obtained utilizing Monte—Carlo method and the results are plotted. Finally, risk analysis can be made from above results.

风险评价方法步骤如下：（1）首先通过岩芯样品的现场观测和实验室试验及钻孔岩体超声波测试获得两种分类所需的变量；（2）通过统计分析和判断得出各变量的分布函数及参数；（3）运用Monte—Carlo模拟方法获得2万个RMR值或BQ值及相应的累积分布函数，并将结果绘成岩体质量描述图；（4）运用以上结果作出岩体质量风险分析。

An algorithm of cluster analysis with statistic significance test to classification was developed in this paper.

鉴于此，本研究用随机化方法对分类进行统计显著性检验，建立了具有统计显著性标记的聚类分析算法，用于对若干个样品进行有显著性标记的聚类分析。

The procedure is as follows: First, the haze area is recognized by using band statistic values, Second, the remote sensing image is classified by using unsupervised classification, then the aerosol optical depth distribution is calculated by comparing the radiation values in haze and clear areas, Finally, the image can be atmospherically corrected by using MODTRAN model.

首先，结合SPOT 5各波段的统计特征，从影像上识别出模糊区；然后，对影像进行非监督分类，对同一分类区内像元在模糊区和清晰区的辐射值进行比较，计算出气溶胶空间分布；最后，将气溶胶分布输入MODTRAN模型中，对影像进行大气校正。
