Bivariate Pearson Ⅲ Distribution is used to estimate the return values of wind velocity and wave height hindcasted in offshore area of southern Bohai Sea. Different criteria of design parameters are compared for marginal oil field exploitation.

在渤南油田后报环境条件的基础上，采用二维伽玛分布进行统计，给出了几种不同的方法推求的多年一遇风速与波高的联合设计值，供边际油田设计部门作出决策参考。

To improve the performance of image-denoising methods, a locally adaptive denoising algorithm was presented. The new algorithm assumed the statistical dependence among wavelet coefficients. First, a bivariate probability distribution model was introduced to model the statistics of wavelet coefficients, and corresponding nonlinear threshold function was derived from the model using the Bayesian estimation theory.
