| 摘 要： | 为解释高温超导晶体的声子Ｒａｍａｎ偏振谱，本文提出两个Ａ＿（ｌｇ）－对称声子模相混的机制。对Ｙ—Ｂａ—Ｃｕ—Ｏ单晶，按偏振Ｒａｍａｎ谱强度比计算了两个Ａ＿（ｌｇ）－振动模的耦合系数。

| Abstract: | The mixing of oxygen vibrational modes of A_(lg) symmetry in the lat- tice of hign-T_c superconductor（SC）are studied．The polarization ratio in the Raman spectra of SC single crystals of YB_(a2)Cu_3O_(7-δ) is investigated and the co-efficient of mode mixing for A_(lg) vibrations was dtermined for it. |
