  边缘概率
     Based on the classic probability of edge(POE) metrics for quantifying background clutter,and the up-to-date research findings in human visual perception,a new method for modifying NVESD's classic human target acquisition performance was proposed. And the modified model was preliminarily validated.
     本文基于边缘概率(POE)背景杂波量化尺度,利用人眼视觉搜索探测特性领域的最新研究成果,提出了一种对经典的NVESD模型进行修正的新方法,并对修正模型进行了初步的验证.

In order to understand the process of ultra-fine comminuting mica with high pressurewater jet, the particle characteristic equation is deducted in this paper with assumption thatthe developing probability of edge crack,surface crack or volume crack in a particle is independant, and that the probbility of any crack developing in a particle is submitted to PoissonDistribution. It is considered that the developing probability of crack is proportional directlyto pressure, and inversely to feed mean particle size. Also, the experimental data of comminuting mica with water jet have been analysed, with the particle characteristic equation. Itis found that comminuting mica with water jet is mainly caused by edge crack developing,and particle size distribution depends on pressure and feed mean particle size.

为了弄清高压水射流超细粉碎云母的规律,本文通过假设颗粒中的校裂纹、表面裂纹和体裂纹的扩展概率相互独立,以及颗粒中发生多少个裂纹扩展的概率服从普哇松分布,推导出粒度特性方程;并认为裂纹扩展概率与水压成正比,与给料调和平均粒率成反比;然后用粒度特性方程拟合和分析了高压水射流超细粉碎云母的实验测试数据,发现高压水射流超细粉碎云母主要是云母粉中的棱裂纹扩展所致,且粒度分布由水压和给料调和平均粒度决定。

Ecotone is zones of transition between adjacent ecological systems, having a set of characteristics uniquely defined by space and time scales and by the strength of the interactions between adjacent ecological systems. It situated where the rate and the dimension of ecological transfers (solar energy, nutrient exchange) have an abrupt change. Ecotonal ecosystems are characterizes by (1) permeability and vector diffusion;(2) semi-permeable membranes function and modification;(3) relative high instability and volatility;(4) a wider amplitude of fluctuating physical and biological processes in arid zone ecosystems;(5) critical threshold. Ecotones of desert-oasis exist at every scale. The structural variables important to ecotones are size, shape, biological structure, structural constraint, internal heterogeneity, ecotone density, fractal dimension, patch diversity and mean patch size. The function of ecotones among desert and oasis are stated, such as passive diffusion, active diffusion, probability of edge encounter and probability of crossing a boundary. The important functional variables are stability, resilience, energetic, functional contrast and porosity. Finally, the future directions for the research of ecotone among desert and oasis are also presented.
