5)Human-being masking effect人耳掩蔽
1.In order to get a better trade off,the subspace technique is introduced,which separates the noisy signal into irrelated signal space and noise space,and then combines with human-being masking effect.传统的减谱技术虽然去噪明显,但在听觉上留下了不舒适的"音乐噪声",为了在主客观上得到更好的折衷,引入了子空间技术,将带噪信号分解为不相关的信号空间和噪声空间,并结合人耳掩蔽效应,在主客观上得到了较好的折衷。

沉淀掩蔽法利用沉淀反应降低干扰离子浓度,以消除干扰离子的方法,称为沉淀掩蔽法.例如,在ca2+,mg2+共存的溶液中,加入naoh使溶液的ph>12,mg2+形成mg(oh)2沉淀,不干扰ca2+的滴定.应该指出,沉淀掩蔽法,不是理想的掩蔽方法,因为它尚存在着如下缺点.(1)一些沉淀反应进行得不完全,掩蔽效率不高.(2)由于生成沉淀时,常有"共沉淀现象",因而影响滴定的准确度,有时由于对指示剂有吸附作用,而影响终点的观察.(3)沉淀有颜色或体积很大,都会妨碍终点的观察.因此,沉淀掩蔽法的应用不很广泛.
