In the spectrum of pyrophyllite containing more quartz the absorptionband tends to damp or vanish.
在含石英较多的叶蜡石红外谱图中，叶蜡石的吸收谱带减弱或消失。
2
The results showed the absorptionband produced by the imperfection, impurity and non diamond phase in films decreased the transmission of the films.
结果表明，膜中的缺陷、杂质和非金刚石相在透射谱中产生吸收带；
3
The band gap, linear refractive indices and absorption coefficients fundamental optical constants of the film were obtained through optical transmittance measurements.
