The result showed that the carrier concentration of IMO was less than one third of that of ITO.So,the absorptance of visible light in IMO is lower than in ITO,there might br more space to improve the conductivity of IMO.

因此，IMO薄膜对可见光的吸收小，有很大的发展空间可以通过提高载流子浓度而进一步提高电导率，对近红外线也有较高的透射率，有利于拓展透明导电薄膜的应用领域。

The photo-induced change in absorption coefficiency and in refractive index and their relationship were summarized.

本章介绍了光照下bR膜的吸收系数和折射率的变化及二者的关系。

While the adsorptions of 1-propanol and 1-Br-propane at 100℃ give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 ℃ shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150℃, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO〓 catalyst.

2原位IR光谱实验结果表明：200℃时丙烷/O〓混合气在催化剂表面吸附后的IR谱与同温度下异丙醇吸附的IR谱相似，均检测到吸附态丙酮物种和丙烯醛物种的IR谱峰；溴代异丙烷和异丙醇在催化剂表面吸附后均转化为异丙氧基，异丙氧基主要转化为丙烯和丙酮，丙烯进一步转化为丙烯醛；溴代正丙烷和正丙醇在催化剂表面吸附后均转化为正丙氧基，正丙氧基主要转化为丙醛；丙烯在催化剂表面吸附后转化为σ-氧烯丙基和异丙氧基，升温后σ-氧烯丙基转化为丙烯醛而异丙氧基转化为丙酮。
