利用角度色散X射线粉末衍射仪和图像板探测器，分别测定了经偏差应变修正后的H和D分别高达106 GPa和60 GPa时的状态方程。我们的数据是根据维奈的普遍状态方程进行分析的。这种处理表明，在大约15和66 GPa处发生了两个二级或更高阶的相变，这与质子无序性质预计会发生变化的压力范围一致。{版权所有}{ITAL 1997}{ITAL The American Physitive Society}
Using angle-dispersive x-ray powder diffraction and image plate detector, the equations of state of H{sub 2}O and D{sub 2}O ice VII, corrected for deviatoric strain, were determined up to 106 GPa, and 60 GPa, respectively. Our data were analyzed on the basis of the universal equation of state of Vinet {ital et al.} This treatment indicates the occurrence of two second- or higher-order phase transitions at about 15 and 66 GPa, in agreement with the pressure ranges where the nature of the proton disorder is expected to change. {copyright} {ital 1997} {ital The American Physical Society}
