查询词典 pascal distribution

Considering the impacts of \'excessive fitting\' and \'unusual point\' on identification, a weighted least squares support vector machine which based on the normal distribution function is proposed in this thesis. Its weighted rules mainly apply some statistical characteristics of the normal distribution faction.

The auther studied the community ecology of soil pro-tozoa by chosing the five representative forest types,korean-pine-broad-leaved forest,broad-leaved-korean-pine forest,korean-pine forest,broad-leaved forest andsylvesfriformis-pine forest in the coniferous-broadleaved mixed forest zone on northern slope of ChangbaiMountain during the summer of 1985-1987 in order tounderstand the composition of species and number of soilprotozoa in different forest types of the coniferous-broad leaved mixed forest zone;species dibersity indexand evenness index of soil protozoa in community;pro-tozoan density and biomass;noteworthiness of the re-gularity of protozoan number variance;distributionpattern in community;horizontal distribution;relation-ship of vertical distribution and soil micro-environ-ment etc.,and compare the similarities and differencesof these five forest types according to feature ofsoil protozoan community,and finally summarize thetheoretical regularity,the index or the evidonceof the best forest-type structure.

本文工作的目的是通过对不同林型下土壤原生动物的群落组成，群落结构特征的研究，以及对凋落物分解过程中原生动物种类和数量的初步调查，来探索土壤原生动物在指示环境条件和林型结构特征方面的可能性作用。

Oilcan is a kind of typical rigid target with big backscattering coefficient, which takes on point figure if the resolution of SAR image is not very high; these point targets to be recognized gather together, and form a target region with some distribution area; the center of the region appears as a beeline, and the speckle noise appears scattered, therefore, considering the different grey distributions between point target and speckle noise region and the space geometry distribution, these point targets can be recognized by this algorithm.

由于在高分辨率情况下，合成孔径雷达图像中油罐个体的散射分别体现为由若干高亮度点围成的椭圆，待识别油罐目标的模糊边缘呈不连续的椭圆状，因此从二值化后的SAR图像中识别出拟目标的不连续边缘，判断其是否满足目标边缘特性来识别出最终结果，采用该方法解决了这类高分辨率下椭圆状目标的识别问题。本文运用了基于Gauss核函数支持向量机的SAR图像典型目标识别方法。

The third member of Dongying Formation Oligocene (Ed3) is one of the major oil producing pays. As the oilfield developing, the contradiction between distribution of reservoir sandbodies and production practice becomes more serious. For further production, it is the key point to get better understanding of sedimentary characteristic and reservoir distribution.
