Using the Shannon-Wiener's niche breadth index and the Pianka's niche overlaps index, we found that the Nereis japonica, nemerteans and eelworms had broad niche breadths (above 2.80); the niche overlaps among them was high (above 0.90) in the quantitative analysis on the 21 species present in the quantitative sample analysis.

对定量取样中获得的21个物种以Shannon-Wiener指数为基础进行了生态位宽度测定，以Pianka重叠指数为基础进行了生态位重叠值分析，结果表明日本沙蚕、纽虫和线虫的生态位较宽，均为2.80以上，它们之间的生态重叠值也较高，均为0.90以上。

The simulation results indicate that comparing with the classical Wiener filter, this method performs better in visual effect, mean square error and peak noise-signal ratio, and is an effective method for image restoration.

仿真实验表明，从视觉效果、均方误差和峰值信噪比等方面进行比较，其恢复效果比经典的维纳滤波法好，是一种有效的方法。

In order to determine the optimal value of noise-signal power ratio, a priori knowledge of image must be known in image restoration in the Wiener filter, which limits its application.
