气体绝缘金属封闭开关设备(GIS)在设计、制造、安装和运行维护时会产生金属异物,导致其内部会发生局部放电甚至电弧放电。通过建立异物对比分析数据库,将GIS相关已知材料及放电异物的成分数据形成系统完善的数据库。在分析放电异物时,通过对放电异物成分数据与数据库中已知材料的成分对比分析,可快速准确地得出放电异物的材料和来源。该GIS放电异物分析方法可为GIS制造厂及用户现场放电事故的调查研究提供可靠的数据支撑,并可为GIS装配、试验、安装过程中如何预防放电异物再次混入提供系统可靠的理论依据。

The first SEASTAR (Shell Evolution and Search for Two-plus energies At RIBF) campaign was carried out inMay 2014. We are analyzing the data for 58??63V and 63??*** experiment was performed at the Radioactive Isotope Beam Factory in RIKEN. A high-intensity 238U beamwas accelerated to bombard beryllium target to produce secondary beams. The B??ΔE??B method was applied toselect and purify secondary beams. An ionization chamber located at the focal point F7 (F11) measured the energyloss ΔE, yielding the fragments' element number Z in BigRIPS (ZDS)[1].

The present study utilized motor imaginary-based brain-computer interface technology combined with rehabilitation training in 20 stroke patients. Results from the Berg Balance Scale and the Holden Walking Classification were significantly greater at 4 weeks after treatment （P 〈 0.01）, which suggested that motor imaginary-based brain-computer interface technology improved balance and walking in stroke patients.

在断路器1 000~2 000次机械操作试验中,30CrNi3合金钢渗氮轴销发生断裂。通过化学成分分析、断口分析、低倍检验、金相检验、力学性能测试的方法,对轴销的断裂原因进行了分析。结果表明:该轴销的断裂性质为双向弯曲疲劳断裂;轴销材料渗氮层存在脉状氮化物,内部存在疏松、大尺寸夹杂物和气泡缺陷,降低了材料的力学性能;在周期性旋转弯曲力作用下,轴销表面缺陷处出现裂纹并不断扩展,最终导致轴销疲劳断裂。

The most neutron-deficient isotopes215,216 U were produced in the complete-fusion reaction ^(180)W(^(40)Ar, 4-5n)^(215,216) U. Evaporation residues recoiled from the target were separated in-flight from the primary beam by the gas-filled recoil separator SHANS and subsequently identified on the basis of correlated α-decay chains. Two α-decaying states were identified in ^(216)U, one for the ground state and the other for the isomeric state with 8+(πh_(9/2)πf_(7/2)) configuration. The α-decay properties for ^(215,216)U and the systematics of 8+isomeric state in N = 124, 126 isotones were investigated.

An attempt has been made recently to synthesize very neutron-decient 216U isotope in 40Ca+natHf reaction atthe gas-lled recoil separator SHANS[1]. A beam of 40Ca12+ at an energy of Elab=194.6 MeV was delivered by thesector focusing cyclotron of the Heavy Ion Research Facility in Lanzhou (HIRFL). The average beam intensity wasabout 100 pnA. Self-support targets of natural hafnium foils with thickness of 420 g/cm2 was mounted in a edframe. Evaporation residues recoiled from the target were separated from the primary beam by the separator andthen implanted into the Si-box detector (consist of three position sensitive silicon detectors and eight non-positionsensitive silicon detectors)[2]. In order to distinguish the -decay events from the implantation events, two multi-wire proportional counters (MWPCs) were mounted upstream from the Si-box detector. Behind the Si-box detectora fourfold segmented Clover detector was installed for -ray studies.
