To search for novel Cu(Ⅰ) complexes,traditional approaches focus on designing and screening ligands,metal precursors and reaction parameters.In this report,we propose a top-down approach,in which Cu precursor is first reduced to nanoparticles in the presence of alkynyl and phosphine ligands.The nanoparticles then undergo an auto-oxidation step in open air to give CuO powder.During this process,a new tetranuclear Cu(Ⅰ) cluster with an unprecedented centered triangular configuration,[Cu4(PhC=C)3(dppp)3]NO3,is iso-lated in the supernatant.To demonstrate the feasibility of such strategy,it is applied to synthesize another two new Cu(Ⅰ) clusters,[Cu6 (PhC=C)5(dppe)3]NO3 and Cu4(PhC=C)4(dpph)2.The latter has shown a photoluminescence at 511 nm with a quantum yield of as high as 69.84％.

中国形象的诗性书写是新世纪文学一种新的表意动向。这种书写实际上是一种重述中国的文学行动,它重构了中国经验与中国故事的讲述方式。这种诗性书写是通过回归与激活传统美学而实现的,传统文化精神与美学风格是它的基本资源依凭。美好人性人情、具审美现代性质素的文化乡愁与故乡记忆、具形而上性质的精神境界与意义世界、神秘地域文化与民族神话叙事等形构了中国形象诗性书写的审美意涵;在艺术形式与话语风格方面,这种书写氤氲着一种古典美学趣味,表现出鲜明独特的“中华审美风范”。从深层文化意味来看,这种书写是新世纪文学关于中国形象

随着司法体制改革带来的司法权力扩增,司法权的监督成为重点。当前,司法责任制带有结果主义导向误区,传统监督机制功能日趋虚化。大数据则为司法权的监督提供了新路径,体现为基于数据采集的实时监督机制,基于数据画像的业绩考核机制,基于知识图谱的证据审查机制以及基于法律推理的偏离度预警机制。大数据司法监督具有全景式监督、预防性监督及算法监督的特征。同时,要注意大数据司法监督中的数据风险和算法风险,防止“监督”演化为“监控”,防范大数据对司法裁判权的过度干预。
