摘要：
Thermal dilatation experiments are performed for partially deuterated triglycine sulphate crystals and the temperature dependence of linear expansion coefficients is studied in the temperature range 77-120 K for the three principal directions. The critical behavior of the crystal due to ferroelectric phase transition is shown to be well described within the first fluctuation correction approach.
