| 摘 要： | 在有界闭区域中按随机抽样原则取点,是地质勘探、环境监测等工程应用领域中的常见问题,所取点应服从在该区域上的均匀分布。本文通过边际分布理论,探讨了在有界闭区域中按照简单随机抽样原则随机取点的一般方法,并通过二维平面上的圆内区域与三维空间中的球内区域,演示了在符号处理软件Mathematica环境下的具体操作。

| Abstract: | It is common to access point randomly in a bounded closed region in engineering applications such as geological exploration and environmental monitoring. The point accessed should be uniformly distributed in the region. By applying the marginal distribution theory,this paper explores the general approach to accessing point randomly in a bounded closed regio. Meanwhile,it demonstrates the specific operation by using the Mathematica software within a two-dimensional circle region and a three-dimensional ball region. |
