摘要
简述核能级的电四极超精细分裂及核四极共振基本原理，并就与核四极共振应用密切有关的、四极核所在处电场梯度（ＥＦＧ）张量的来源进行讨论。
The quadrupole hyperfine splitting of nuclear energy levels and the fundamentalprinclple of nuclear quadrupole resonance（NQK）are described，and the origin of electric fieldgradient（EFG ） tensor located at atomic nucleus is discussed， which is involved closely withthe applications of EQR.
