Based on the electronic focus technology development of state-of-the-art,the paper suggested a complete apparatus s cheme ofauto-focus based on SSPD(self-scanned photodiode array)and 8098 singl e chipprocessor,giving out a focus criterion algorithm based on image high freq uencystatistics.The function of auto-focus of both reflected and transparent o pticalmicroscope was realized.Meanwhile some corresponding problems such as sta bility of lightsource,step motor driving etc.were also discussed,which greatly improved the accuracy andreliability of the system.

文摘：在介绍与分析了国内外电子调焦系统的技术发展与现状的基础上，提出了一种基于SSPD与8098单片微处理器自动调焦的整体技术方案，给出了基于图像高频成分统计的聚焦判识算法，在此基础上实现了反射式与透射式光学显微镜的自动调焦，同时对系统的可靠性有关的其它相关问题如光源稳定性、步进电机驱动等问题也进行了讨论。

Audio denoising is the pre-step in the audio processing,and wavelet domain denoising has been a main research area.In order to give people a summary knowledge of wavelet domain audio denoising,based on many literatures,this paper attempts to make a survey of wavelet domain audio denoising.First,it introduces wavelet transformation and the characteristics,and gives the optimal selecting and dealing criterion of wavelet domain denoising,the basis wavelet selection.Second,describes five classical methods of audio denoising,for example,threshold,multi-wavelet,wavelet packet,modulus maximum and scale correlation,then introduces their development.Third,introduces a new algorithm based on modulus maximum and scale trading theory.At the end,the future trend of wavelet domain audio denoising is pointed out.

音频降噪是音频处理前期的必要步骤，小波域降噪是其中一个重要的研究方向，为了使人们对小波域音频降噪有概括了解，在对小波域音频降噪相关文献进行分析和理解的前提下，首先介绍了小波变换及其特性，同时阐述了小波降噪的最优选取和处理准则，及对音频进行小波变换时小波基的选取原则；然后评述了用于音频降噪的阈值，多小波、小波包、模极大值和尺度相关法等5类方法及各自的发展；接着介绍在前人基础上，提出新的基于模极大值和尺度理论的降噪算法；最后探讨了小波域音频降噪的发展方向。

The methods of stress and strain analysis, failure analysis and safety evaluation for high arch dam in available specification and studies are reviewed in this paper. The main deficiencies for these methods are: the failure modes are not taken into account in failure analysis and safety evaluation, the regimes of failures are not clearly defined, the related methods and criterion are not so reasonable.
