Identifying the real fracture of rock hidden in acoustic emission(AE)source clusters(AE-depicted microcrack zone)remains challenging and *** we revealed the AE energy(representing dissipated energy)distribution rule in the rock microcrack zone and proposed an AE-energy-based method for identifying the real fracture.(1)A set of fracture experiments were performed on granite using wedgeloading,and the fracture process was detected and recorded by *** microcrack zone associated with the energy dissipation was characterized by AE sources and energy distribution,utilizing our selfdeveloped AE analysis program(RockAE).(2)The accumulated AE energy,an index representing energy dissipation,across the AE-depicted microcrack zone followed the normal distribution model(the mean and variance relate to the real fracture path and the microcrack zone width).This result implies that the nucleation and coalescence of massive cracks(i.e.,real fracture generation process)are supposed to follow a normal distribution.(3)Then,we obtained the real fracture extension path by joining the peak positions of the AE energy normal distribution curve at different cross-sections of the microcrack ***,we distinguished between the microcrack zone and the concealed real fracture within *** deviation was validated as slight as 1–3 mm.

Fast beam profile measurement is important in fast beam dynamic behavior investigations. A bunch-bybunch beam size measurement system, which is presently used to measure horizontal profile, has been developed at the Shanghai Synchrotron Radiation Facility(SSRF) and is capable of measuring bunches within a separation of 2 *** system is based on a direct-imaging optical system and high-speed photomultiplier array detector. A high-bandwidth linear signal amplifier and acquisition module have also been designed to process bunch-by-bunch multichannel signals from the detector. The software resampling technique and principal component analysis method were developed to obtain the synchronized data and enhance the signal-to-noise ratio. The fast injection of transients was successfully captured and analyzed. Moreover, the bunchby-bunch positions and sizes exhibited strong oscillation after the injection at the horizontal betatron oscillation frequency of the SSRF storage ring, and this demonstrated the bunch-by-bunch measurement capability of our system.

创新创业是新发展阶段构建新发展格局和实现高质量发展的重要议题。将内涵和外延原有异同的创新与创业的两个概念定义为一个集合概念,进而结合数字化转型中介作用,探讨创新创业促进区域经济高质量发展的效应及其影响机制。考察分析表明:创新创业显著促进经济高质量发展;数字化转型在创新创业与经济高质量发展之间存在间接中介效应。采用IRIEC指数、Moran’I指数法和空间杜宾模型衡量创新创业空间效应,发现创新创业不仅会对本地区的经济高质量发展产生显著的正向影响,还对相邻区域的经济高质量发展产生正向的溢出效应。异质性分析发现,东部地区享受到的创新创业释放红利比中西部和东北地区更大。鉴于此,应着力提升区域创新创业能力,发挥数字化转型在创新创业进程中的作用,推进建立创新创业多元协同运行机制,以促进经济高质量发展。

Areca catechu L.（Palmae）, commonly known as an important economical seed crop, is widely culti- vated in tropical and subtropical areas, including India, Southeast Asia, East Africa and New Guinea. Areca nut（frequently known as betel nut） is the ripe fruit of the tree A. catechu. Areca nut can be chewed and it is a common masticatory in tropical and subtropical countries. It was estimated in the early 1990s that 10% to 20% of the world＇s population chewed betel quid daily. Areca nut is commonly used in folklore medicine for treatment of various diseases such as dyspep sia, constipation, beriberi and oedema.
