在5~400K温度范围内测量了K3H(SeO4)2及其部分氚晶体的介电常数，发现K3H(SeO4)2在20K左右发生相变，并伴随着一个小的介电常数峰值，经过约70%的氢化，介电常数的峰值从20K移动到73K。
The dielectric constants of K 3 H(SeO 4 ) 2 and its partially deuterated crystal were measured from 5 K to 400 K. It was found that K 3 H(SeO 4 ) 2 undergoes a phase transition accompanied with a small peak in the dielectric constant at about 20 K. The peak of the dielectric constant was shifted from 20 K to 73 K by deuteration of about 70%.
