在高达0.7 GPa的静水压力下研究了（1-x）Pb（In 1/2 Nb 1/2）O3-xPbZrO 3（Zr-PIN）和（1-x）Pb（In 1/2 Nb 1/2）O3-xPb（Yb 1/2 Nb 1/2）O3（Yb-PIN）混合晶体系统的介电性能。在这些系统中存在显著的压力效应。在Zr-PIN（x=0.1）中，指示介电常数最大值的温度Tm以dTm/dp的速率降低|p=0=−54 °C/GPa，且Δ ′随压力增加而减小，而在Zr-PIN（x=0.34）中，Tm以dTm/dp的速率减小|p=0=−100 °C/GPa，随着压力的增加，ε ′减小，tan δ的最大值（记为tan δm）增加。对于Yb-PIN（x=0.16），Tm以dTm/dp=155 °C/GPa的速率增加，Δ Tm ′和tan δm均随压力增加而减小。
Dielectric properties of (1−x)Pb(In1/2Nb1/2)O3−xPbZrO3(Zr‐PIN) and (1−x)Pb(In1/2Nb1/2) O3−xPb(Yb1/2Nb1/2)O3(Yb‐PIN) mixed crystal systems were investigated under hydrostatic pressures up to 0.7 GPa. There are striking pressure effects in these systems. In Zr‐PIN (x=0.1) the temperature Tm, indicating the maximum of the dielectric constant, erm′, decreases at the rate of dTm/dp|p=0=−54 °C/GPa, and the erm′ decreases with increasing pressure, while in Zr‐PIN (x=0.34) the Tm decreases at the rate of dTm/dp|p=0=−100 °C/GPa, and the erm′ decreases and the maximum value of the tan δ, denoted as tan δm, increases with increasing pressure. For Yb‐PIN (x=0.16) the Tm increases at the rate of dTm/dp=155 °C/GPa, both the erm′ and the tan δm decrease with increasing pressure.
