声谱仪

在CO2激光光声谱仪上，对T形腔性能的测量结果表明，耦合谐振光声腔有高达900左右的Ω值；

With the CO2 laser photoacoustic spectrometer the measured results of the T-type cell prove that it has a high quality factor Q ( up to 900 ) .

应用红外光谱仪、分光光度计、光声谱仪和正电子湮没寿命谱仪，从不同的角度，研究a-Si：H和a-SiNx：H薄膜中的成分、缺陷以及光生载流子的非辐射复合。

The defects and the nonradiative recombination of photogenerated carriers in a-Si : H and a-SiNx : H films are studied by using infrared spectrometer , spectrophotometer , photoacoustic Spectrometer and positron annihilation life-time spectrometer from various respects .

在以上两个例子里，对于一个说英语的人，这两个词都几乎无法分辨，但通过声谱仪处理后却能形成明显不同的图案。

In both cases , the two words are nearly indistinguishable to an English speaker , but yield starkly different patterns when run through a spectrograph .
