| 摘 要： | 本文采用Ｕ－Ｂ力场在位置群近似时对锆石中ＳｉＯ＾４－４离子的内振动进行了简正坐标分析，振动频率的计算值与观察值吻合很好。根据简正坐标分析确定的力常数值为Ｋｒ＝４００，Ｈ１＝４４，Ｈ２＝６０，Ｆ＝２５Ｎ．ｍ＾－１。

| Abstract: | Normal coordinate analysis has been carried out for the internal vibrations of SiO ions in zircon using the Urey-Bradley force field. The calculated vibrational frequencies are in reasonably good agreement with those observed- The valus of the force constants so obtained are: Kr= 400,H1=44, H2= 60, and F=25 N. m-1. |
