| 摘 要： | 针对地面研究用岩石的热红外光谱反演其矿物组分过程中,由于自然岩石内矿物组分分布不均匀,给确定观测区域内矿物组分的精确值造成困难的问题,该文采用块状矿物拼接的方法模拟自然岩石,使模拟岩石的矿物组分可以精确获取。进一步,针对模拟岩石制订旋转试样法观测方案,从理论上研究该方案存在的观测误差,并通过光谱解混验证其观测精度。

The experiment study of infrared spectral deconvolution to the mineral component in massive rock |

| Abstract: | Aiming at the problem that it is difficult in acquiring the truth-value of mineral component of rock in the spectrometer spot because the mineral is not well-distributed in natural rock when study the way of obtaining the mineral composition of rocks by thermal infrared spectroscopy on the ground,natural rock was simulated by the way of mosaicking the massive minerals in the experiment in this paper.What's more,the observation scheme of rotating sample was used in simulated rock.The observation error of this scheme was theoretically studied,and observation accuracy of this scheme was validated with spectral deconvolution. |
