In order to reduce the musical residual noise and the background noise, a speech enhancement method based on masking properties of the human auditory system is described. this method uses bark wavelet packet transform to simulate the frequency feature of human auditory model to get the threshold
本文以最大限度減少殘留噪聲和背景噪聲為目的，採用bark子波分析的方法模擬人耳基底膜的頻率分析特性來進行語音增強，重點進行模擬人耳聽覺掩蔽效應來確定除噪閾值的研究。The purpose of this thesis is to develop the laser assisted wet chemical etching on the gaas substrate. the main contents and contributions include : 1 ) laser - assisted wet mask - etching method and poles - etching method have been proposed laser - assisted wet mask - etching method is that the area which need not etched is covered by mask film, and the uncovered area is processed by laser induced wet etching
本文的工作就是圍繞半導體gaas基片的激光化學誘導液相腐蝕技術開展的，主要的研究結果和創新之處如下: 1 ）提出了激光誘導液相抗蝕膜掩蔽法和電極腐蝕法抗蝕膜掩蔽法是指在基片表面不需要腐蝕的區域用抗蝕膜覆蓋，激光照射在無抗蝕膜區域，對基片進行腐蝕。In order to make integration of theory with practice, a lot of experiments have been done. mask - making technology, photoetching and wet - etching processes have been optimized. the author also presents the application and commercial value of silicon v - groove arrays
在實踐上，對製作工藝積極探索，提出新的制備硅掩蔽膜的工藝方案，對影響光刻質量的因素深入分析，試驗摸索出適用於v型槽的各向異性濕法腐蝕的腐蝕液配方，獨立優化設計了製作硅v型槽的相關工藝，製作出高質量的硅v型槽。
