摘　　要：本文用半经验方法给出了Ａ≥７０的偶偶核的有效玻色子数，收集了玻色子数饱和的有关证据，并采用有效玻色子数概念，处理了内禀电四极矩Ｑ０与ＮπＮｖ（Ａ≥７０的偶偶核）系统关系，得到了Ｑ０的经验公式．本文采用所给的有效玻色子数对（１４２）Ｃｅ和（１４４）Ｎｄ进行了数值计算。The methods to obtain effective boson numbers are reviewed briefly, and the evidence for the existence of the saturation phenomenon of effective boson numbers is collected. With the effective boson numbers presented by a semi-empirical method,formula of intrinsic quadrupole moment Φo as a function of NπNv for even-even nuclei with A ≥ 70 are presented, and 142Ce and 144Nd are calculated numerically. These results are satisfactory.
