The bio-leaching and multi-liquid arrangement technologies are the effective measures to overcome the "inert corner" and geochemical layering problems in-situ crushed leaching process of uranium.

The Gumbel-hougaard Copula function was used to analyze the joint distributions between annual maximum daily storm and seven-day storm amounts which are both with Pearson type III marginal distributions.

A bivariate joint distribution with Pearson Type III distribution margins is developed based on Gumbel-Hougaard Copula and used to describe two seasonal maximum flood series.

This paper proves joint distributions of multiple order statistics different from other documents;then studies distributions of single order statistic on the basis of joint distributions of multiple order statistics;finally systematically studies condional distributions of order statistics.

The Gumbel-Hougaard Copula was employed to construct a bivariate joint probability distribution for describing flood peak and flood volume,whose marginal distributions are both the Pearson type Ⅲ.

A joint probability distribution model of the tide level is established in the Wusongkou and the rainfall in the Taihu Lake area for calculating the probability of occurrence of the specified design tide level in Wusongkou,the design rainfall in Taihu Lake area and the corresponding rainfall in the reach.

The period non-stationary probability and thejoint probability distribution for the system are aCquired.
