摘　　要：运用半定量半定性研究方法 ,依据经典统计规律对极性分子的极化程度作了研究。通过计算 <cosθ >,得出极性分子永久极矩沿外场方向有序排列的表达式 ,并得到永久极矩沿外场方向排列的有序程度很小的结论。The polarized degree of polar molecule is studied based on the classic statistic law and semi_quantitative, method. And thus the formula of < cosθ >, which expresses the ordered degree of electric moment of polar molecule in field direction, is calculated. Therefore, a conclusion can be drawn that the ordered degree of electric moment is very little.
