Constructing type II heterostructures represents a widely recognized strategy for enhancing charge separation and photocatalytic efficiency,but it remains challenging to fabricate homologous heterostructures based on visible-light-responsive semiconductors,especially for popularly investigated （oxy）nitrides with low thermal ***,we synthesized a homologous heterostructure （denoted as YTON＿H） based on the oxynitrides of YTaO4-xNyand YTa *** heterostructure exhibits type II band structure alignment and intimate interface achieved through a magnesium （Mg） powder-assisted nitridation *** with widely reported heterologous heterostructures,the as-obtained YTON＿H homologous heterostructure could similarly exhibit enhanced charge separation as well as photocatalytic water splitting performance with respect to its counterparts(YTaO4-xNyand YTaON2).Meanwhile,detailed structural characterizations and spectroscopy analysis have been made to confirm the formation of heterostructure and promotion of spatial charge separation.

The instantaneous detection of entanglement in quantum states poses a significant challenge in the fields of quantum computation and quantum information, and there are no practical methods or tools to complete this task satisfactorily so far. We propose a sufficient and necessary criterion of k-nonseparability for any n-partite finite or infinite dimensional systems, 2 ≤ k ≤ n. This criterion serves as the foundation for a practical scheme designed to detect entanglement and k-nonseparability across multipartite finite-dimensional systems. To exemplify the application of our scheme, we have developed a software tool that facilitates swift and precise identification of entanglement, k-nonseparability, and genuine entanglement within n-qubit systems, specifically tailored for systems with 2 ≤ n ≤ 4.

为获取最优工艺参数组合,采用层次分析法并结合BP神经网络（AHP-BP）来确定铝板冲压工艺参数。首先按等深拉延、均匀变形原则,设计满足符合试验条件的工艺补充面;其次,采用层次分析法确定压边力、拉延筋直径以及摩擦系数的权值;通过正交试验获取多组分析结果,构建基于层次分析法BP网络模型,并依据网络模型预测值与CAE分析值的接近程度来确定最优的工艺参数组合,压边力、拉延筋直径以及摩擦系数分别为：135 t、20 mm、0. 2;最后,将AHP-BP网络输出的回弹值作为模具的修正的基准值,并加工实物进行验证。结果表明：将拉延工艺模型回弹修正量设为AHP-BP模型预测值的1. 2倍比较合适。
