quadrupole

n.

四极；

1. It was quadrupole since abolished-Kyushu, Nu Wa Sky after the rare good day.
   那是自四极废，九州裂，女娲补天之后出现的难得的好日子。
2. In order to discuss the possible measurement of order parameters, NMR quadrupole splitting in liquid crystal is considered.
   为讨论序参数的实验测量，本文考虑核磁共振实验中液晶分子的核电四极矩所产生的能级分裂。
