中文摘要：
利用THz—TDS测定了一些化合物在THz波段的光谱性质，并得到不同物质在THz波段的吸收系数，折射率数值。实验结果显示，在0．2～1．5THz波段内，许多常见的非线性光学晶体（如硼酸盐，黄铜矿类化合物）的吸收系数很小（〈10cm^-1）。同一种物质的多晶样品和单晶样品的对比实验表明，多晶样品和单晶样品有相似的THz波段透过率。
英文摘要：
The spectrum properties of several nonlinear optic crystals by THz-TDS system was measured.The results show that , between 0.2-1.5 THz, most borates and chalcogenides have low absorption coefficient（ 〈 10 cm^-1）. According to the result, poly-crystal samples have similar transmittancy compare to single-crystal samples in the band between 0.2-1.5 THz.
