| 摘 要： | 从介电常数与反射串的普遍联系出发，推导出反射光谱灵敏度的解忻表达式。从这个统一的公式出发，分析了Ｌｏｒｅｎｔｚ振子及Ｄｒｕｄｅ自由载流子的反射光谱的敏感性，从而更深入地解释了一些碱卤晶体剩余反射带短波边的异常反射光谱结构及高温超导体的红外反射光谱特征。

| Abstract: | We have deduced a formula for sensitivity of reflection spectrum from the general relation between dielectric constant and reflectivity. Using this unified formula, we have analyzed the sensitivity of reflection spectra of Lorentz oscillator and Drude free carrier, thus we have got a deeper understanding of the abnormal reflection-spectrum structures on the short-wave side of reststrahlen bands of some alkali-halide crystals and the feature of infrared reflection-spectrum of high-Tc superconductors. |
