“系统绕行时间的四分之一”的意义及应用讨论

时间序列相空间重构中,时间延迟参数选择具有重要意义。文章（１）提出,一般可以用时间序列平均绕行时间的四分之一作为二维混沌吸引子重构的时间延迟,文献（２）建议使用系统伪周期的四分之一。     

Structural Domain Imaging and Direct Determination of Crystallographic Orientation in Noncentrosymmetric Ca_3Ru_2O_7 Using Polarized Light Reflectance

The noncentrosymmetricity of a prototypical correlated electron system Ca₃Ru₂O₇ renders extensive interest in the possible polar metallic state,along with multiple other closely competing interactions.However,the structural domain formation in this material often complicates the study of intrinsic material properties.It is crucial to fully characterize the structural domains for unrevealing underlying physics.Here,we report the domain imaging on Ca₃Ru<...
