摘要：

We have investigated the fragility of glycerol, propylene carbonate, and metafluoroaniline at pressures tip to 700 MPa using dielectric spectroscopy. All three small-molecule glass formers do not show a pressure dependence of fragility within experimental error. The ratio of glass transition temperature and Vogel-Fulcher-Tammann temperature is pressure independent. The results are discussed in the frame of the detect diffusion model.
