摘要
利用在红外分光光度计上实验测出三种黑龙江省产煤及其灰的稀相均一微粒弥散系的透射率光谱,结合精确Lorenz-Mie电磁理论及色散K—K关系式.反演微粒的基本辐射特性参数(复折射率),并进而求粒子的衰减因子、散射因子和吸收因子.由于计算的唯一简化条件为有限区域实验数据的外推关系式.因而本文方法精度高.适用范围广。本文对透射率实验误差对反演结果的影响进行了分析.指出透射率的实验精度将影响复折射率的求解。
Through the utilization of the transmissivity spectrum of rare-phase homogeneous microperticle dispersion system of three types of Heilongjiang Province coal and its ash, experimentally determinned by an infrared spetrophotometer, coupled with the adoption of a coly precise Lorenz-Mie electromagnetic theory and dispersion K-K relation, the authors have made an inverse computation of the bole radiation characteristics parameters (compound refractive index) of microperticles and on ho bets determined the decay factor, scattering factor and absorption fractor of the said particles. As the only simplificationn condition of the computation is the extrapolation relation of a limited domain experimental data, the method under discussion in ho paper features high precision and a wide applicability. The authors have analysed the effect of transmissivity experimental error on the result of inverse computation and pointed out that the experimental precision of the transmissivity will exercise an influence on the solution of the compound refractive index.
