查询词典 inaudibility

The experimental results show the two practical algorithms can preserve inaudibility and they are robust enough to against the different signal processing operations. In addition, the watermarking information can be embedded into the original audio signal adaptively, which also doesnt require the use of the original audio signal for detection. Furthermore, it can resist the different attacks, such as lossy compression (MP3), filtering, resampling and requantizing, etc.

仿真实验结果表明，两种方法都具有较强的鲁棒性和不可感知性，水印嵌入容量的自适应性，提取水印时不需要原始音频信号的参与，且对包括MP3有损压缩、低通滤波、重采样/重量化等多种攻击性试验具有较强的稳健性，是可行的数字音频水印算法。

Infrasound (0.0001-20Hz) is acoustic energy with characters of little attenuation and long distance during radiation, inaudibility, diffraction and resonance in some parameters.

次声波是频率为0.0001Hz-20Hz的声波，具有传播衰减小、传播距离远、易于衍射、一般听不到、达到一定参数可引发共振等特点。

But realization of inaudibility for audios is much more difficult than realizing invisibility for images, the reason for this is that audio signals are represented by much less samples per time interval compared with images and video.

但是由于人耳听觉系统(Human Auditory System，简称HAS)比人眼视觉系统(Human Visual System，简称HVS)灵敏、以及音频作品的采样点数较少等缘故，使得音频数字水印实现不可感知性比较困难。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
