It is found that generally the hydrologic noises exhibit skew characteristics, so that it is reasonably to use skew probability distribution to describing the noise components, and the wavelet coefficient threshold obtained by optimal entropy criterion based on information entropy theory in the global optimum.

分析结果显示，水文序列中的噪声成分具有偏态特性，因此本文应用偏态分布线型对噪声成分进行描述更为合理，而且小波系数阈值优选熵准则所得的阈值是基于信息熵理论而确定的，因此是整体上最优值。

By study of the statistic characteristics of flood forecasting errors and their confidence intervals for Nushi watershed at Sanhuajian of the Yellow River and on the basis of a comparison of the precision criterion currently used for flood forecasting with the result of the error confidence interval method, it is concluded that the error of flood forecasting is of the characteristic of skew probability distribution, and that the evaluated results of forecasting errors are different by the above two methods.

因此，本文在三花间伊河卢氏流域洪水预报的基础上研究了误差置信限及误差置信限评定方法，并将误差置信限评定结果与现行水情预报精度标准[1]评定结果进行了比较。1 现行洪水预报评定方法流域洪水预报精度评定内容包括洪峰流量、峰现时间和洪量等。洪水预报误差指标有绝对误差、相对误差和确定性系数3种。预报误差小于许可误差时为合格预报。

Upon the conditions addressed,an improved parameter-dependent l2-l∞ performance criterion is established by the introduction of a slack variable,which exhibits a kind of decoupling between Lyapunov functions and system matrices.
