对 307 颗有可靠磁场测量值的 CP 星分析其纵向磁场分量 $B_z$ 符号分布，用均方根场和 $B_z$ 极值分类场配置，发现不可逆星中负 $B_z$ 占优，五次以上独立测量子样本也类似，不对称性起源待后续研究。
AI 中文摘要
对 307 颗具有可靠测量磁场的化学特殊（CP）星样本的纵向磁场分量 $B_z$ 的符号分布进行了分析。对于每颗恒星，均方根场 $B_{\rm rms}$ 和 $B_z$ 的极值用于将场配置分类为可逆或不可逆。在 173 颗不可逆恒星中，100 颗主要呈现负 $B_z$ 符号，而只有 73 颗呈现正符号，负极性比正极性约多 1.37 倍。至少有五次独立测量的恒星子样本（254个对象）得到了类似的1.38比例，证实了这种不对称性的稳健性。在太阳附近的不可逆 CP 星中，观测到的负 $B_z$ 值占主导地位具有统计学意义。这种不对称性的可能起源仍不清楚，将在未来的研究中探讨。
英文摘要
An analysis of the distribution of signs of the longitudinal magnetic field component $B_z$ is presented for a sample of 307 chemically peculiar (CP) stars with reliably measured magnetic fields. For each star, the root-mean-square field $B_{\rm rms}$ and the extreme values of $B_z$ are used to classify the field configuration as either reversive or non-reversive. Among the 173 non-reversive stars, 100 exhibit a predominantly negative $B_z$ sign, while only 73 display a positive sign, corresponding to an excess of negative polarities by a factor of about 1.37. A subsample of stars with at least five independent measurements (254 objects) yields a similar ratio of 1.38, confirming the robustness of the asymmetry. The observed predominance of negative $B_z$ values among non-reversive CP stars in the solar neighbourhood is statistically significant. Possible origins of this asymmetry remain unclear and will be addressed in future studies.
