| 摘 要： | 文章采用介电谱方法对升温过程中乙醇的复介电常数实部ε’和虚部ε″随温度T的变化进行了测量。结果表明,升温过程中在100K～180K的温度范围内ε’主要有两个变化过程Kα和Cd,而ε″也有两个变化过程Pα和Ld。

| Abstract: | The glass transition of the ethanol was measured by dielectric spectroscopy method during heating process.The qualitative analysis on the trend of the real and imaginary parts of complex permittivity of the ethanol is given out,which show that there are two main changes when the temperature is between 100K and 180K,namely,and of and the other two changes are and of. |
