摘　　要：用干涉法测量了LAP晶体全部压电系数。结果为:d_(21)=2.9×10^(-12)C/N,d_(22)=-8.2×10^(-12)C/N,d_(23)=-1.5×10^(-12)C/N,d_(25)=-11.8×10^(-12)C/N,d_(14)=5.6×10^(-12)C/N,d_(34)=-2.6×10^(-12)C/N,d_(36)=2.4×10^(-12)C/N,d_(16)=6.6×10^(-12)C/N。The complete set of the piezoelectric constants of LAP crystalswere determined by the interferometric mothod. The results obtained are asfollows: d_(21)=2.9×10^(-12)C/N, d_(22)=-8.2×10^(-12)C/N, d_(23)=-1.5×10^(-12)C/N, d_(25)=11.8×10^(-12)C/N, d_(14)=5.6×10^(-12)C/N, d_(34)= - 2.6×10^(-12)C/N, d_(36)=2.4×10^(-12) C/N,d_(16)=6.6×10^(-12)C/N.
