2014我们在这里报告了对八种纯化合物的压力研究,所有这些化合物在大气压下都表现出可重入的双相。在所有情况下,近晶A-A相边界具有椭圆形状。对于两种物质,近晶A-重入相变在高压下将其特征从单致转变为各向异性。近晶A相稳定的最大压力与大气压下向列相的范围有关。J. Physique 44(1983)51-55 JANVIER 1983,1
2014 We report here pressure studies on eight pure compounds all of which exhibit the reentrant nematic phase at atmospheric pressure. In all cases the smectic A-nematic phase boundary has an elliptic shape. For two of the substances, the smectic A-reentrant nematic transition changes its character from monotropic to enantiotropic at high pressures. The maximum pressure of stability of the smectic A phase is seen to be related to the range of the nematic phase at atmospheric pressure. J. Physique 44 (1983) 51-55 JANVIER 1983, 1
