In this work,we systematically study the two-proton (2p) radioactivity half-lives using the two-potential approach,and the nuclear potential is obtained using the Skyrme-Hartree-Fock approach and the Skyrme effective interaction of SLy8.For true 2p radioactivity (Q2p ＞ 0 and Qp ＜0,where Qp and Q2p are the released energies of the one-proton and two-proton radioactivity,respectively),the standard deviation between the experimental half-lives and our theoretical calculations is 0.701.In addition,we extend this model to predict the half-lives of 15 pos-sible 2p radioactivity candidates with Q2p ＞ 0 obtained from the evaluated atomic mass table AME2016.The calcu-lated results indicate a clear linear relationship between the logarithmic 2p radioactivity half-lives (log10T1/2) and coulomb parameters[(Z0.8d +l0.25)Q-1/22p]considering the effect of orbital angular momentum proposed by Liu et al.[Chin.Phys.C 45,024108 (2021)].For comparison,the generalized liquid drop model (GLDM),effective liquid drop model (ELDM),and Gamow-like model are also used.Our predicted results are consistent with those obtained using other relevant models.

在诸多断裂刻画的案例中,往往是利用相干体对断裂进行刻画与描述,但是相干体在一定程度上对断裂的识别不够精细准确.因此本文提出了基于导向滤波的分频相干体的断层自动提取技术(Auto Fault Extraction,AFE),并针对特定工区改进了断裂识别的技术流程.首先在原始地震记录的基础上使用频谱分解技术生成多个分频数据体,再对分频数据体进行构造导向滤波,之后采用高精度相干算法对每个分频数据体求取相应的分频相干体,通过对比不同分频相干体选择出刻画工区内断裂带的优势频段,并使用带通滤波技术进行切除,最后在带通
大地电磁(MT)法的二维反演算法种类较多,在实际应用中如何选取合适的二维反演方法仍是一个关键问题.通过对比典型理论地电模型与不同反演方法的应用效果,可为实际MT探测反演方法的选择提供参考.本文对数据空间共轭梯度法(DCG)、非线性共轭梯度法(NLCG)以及有限内存拟牛顿法(L--BFGS)三种常用的MT二维反演算法进行对比.首先描述了三种方法的基本原理,然后设计了两个典型的地电模型,对TE、TM、Tzy三种不同模式的数据组合进行了反演试算,分析了这三种模式下不同反演算法的效果.得出3点结论:①三种方法均能

We perform a systematic study on the effect of non-uniform track efficiency correction in higher-order cumulant analysis in heavy-ion collisions.Through analytical derivation,we find that the true values of cumulants can be successfully reproduced by the
