摘要
通过分析ＫＤＰ（磷酸二氢钾）晶体处于顺电相时结构的对称性，说明其所属点群为 Ｄ２ｄ（４２ｍ）的真正原因，并利用晶体的压电效应加以验证，然后用于讨论ＫＤＰ晶体的线性 电光效应，说明它由单轴晶到双轴晶的转变．
Through analyzing the structural symmetry of Potassium Didydrogen-phosphate (KDP) crystal in paraelectric phase, illustrate the real reason of the point group D2D which it belongs to. Utilize its piezoelectric effect to confirm. Then study its linear electro-optical effect using above results. Explain the transition from uniaxial to biaxial crystal.
