测量了Cs3H（SeO4）2和Cs3H03D07（SeO4）2晶体的介电常数和电导率。用X射线衍射法测定了Cs_3H（SeO_4）_2中Ⅰ、Ⅱ、Ⅲ相的对称性和晶体结构。在三角相I中产生的位置质子无序被证明在原则上不同于氢键中两个可能的位点之间的质子无序。
Abstract In Cs3H(SeO4)2 and Cs3H0 3D0 7(SeO4)2 crystals dielectric constant and conductivity were measured. The symmetry and crystal structure of the phases I, II and III, in Cs3H(SeO4)2 were determined by means of X-ray examination. The positional proton disorder arising in the trigonal phase I was shown to differ in principle from the proton disordering between the two possible sites in the hydrogen bond.
