The depth of excavated areas can be ascertained with the reflectance coefficient method or using the automatic calculating program of the depth in direct current electrical prospecting developed by China Mining University.
采空区埋深则可利用反射系数法和中国矿业大学编制的直流电测深自动拟合反演程序予以确定;
The optical refractive index and extinction coefficient were derived by simultaneously fitting the transmittance and reflectance spectra in the wavelength region of 2~ 12.5 μ m.
通过拟合2~12.5μm波长范围的反射和透射光谱,得出了薄膜在此区间的折射率和消光系数。
