摘要：
The results of a study of the permittivity epsilon GREEK TONOS and the third harmonic coefficient gamma(3 omega) of diisopropylammonium iodide (DIPAI), embedded in porous glass with a pore size of similar to 100 nm, are presented. For DIPAI in pores, the temperature of the lower phase transition upon heating increases by 5 K, compared to bulk DIPAI, and is 368 +/- 1 K. The upper phase transition is not observed up to 450 K, which is close to the melting point of DIPAI (similar to 453 K). Upon cooling, one phase transition is observed at a temperature of 364 +/- 1 K.
