It is very difficult to make differences between hardware instrumentation and software instrumentation since through DSP (Digital Signal Processing) technology many deconvolution mathematical algorithms can be included into the instrumentation by Ic techniques to improve the instruments’ resolution. However, digital signal processing can always show some strange results due to noise sensitivity of inverse procedure, singular value problem, divergence problems, ring effects which make the deconvolution results difficult to explain. Further more, the limitation of the

The University of Hong kong positron beam employs conventional magnetic field transport to the target, but has a special hybrid lens design around the positron moderator that allows the beam to be focussed to millimeter spot sizes at the target. The hybrid lens consists of conventional Soa emersion lens that extracts positrons optimally from the moderator in a magnetic field free region. An einzel lens then focuses the positrons into the magnetic funnel at the end of transportation magnetic

第九届全国正电子谱学会议

作者： P.Y.kwan c.k.cheung c.D.Beling S.Fung Department of Physics The University of Hong KongPokfulam RoadHong KongP.R.C.

There are many advantages to being able to perform PALS (Positron Annihilation Lifetime Spectroscopy) using a variable energy positron beam, the most obvious being the easy identification of different defect types. The difficulty in conducting VE (Variable Energy) PALS studies lies in the fact that a "start" signal is required to signal the entry of the positron into the target. Two methods have been used to overcome this problem, namely the bunching technique which employs RF cavities and choppers, and secondly the use of secondary electrons emitted from the target. The latter technique

食用菌虎奶菇在三个不同生长阶段(包括菌丝、菌核和子实体)的细胞壁中均含有大量的超支化多糖。菌丝细胞壁中的多糖为杂多糖,分子量和粒径分别为4.502×104g/mol和33.2 nm,其主链由→1)-D-Glcp-(6→残基构成,并由部分→1)-D-Glcp-(4→和→1)-D-Glcp-(3→残基构成侧链,末端含有少量甘露糖、木糖和鼠李糖,分支度为45%。而菌核和子实体细胞壁多糖则主要由具有相似结构的超支化β-葡聚糖构成,该多糖主要由→1)-D-Glcp-(4→主链和→1)-D-Glcp-(6→侧链构成,并有少量→1)-D-Glcp-(3→存在于侧链中。主要分支位点在主链葡萄糖的O-3和/或O-6位,分支度为63%～70%。该类多糖分子量超过10g/mol,但粒径较小,仅为35 nm左右。进一步的结构分析发现,这类具有致密结构的超支化多糖具有类似支链淀粉的空间结构和内部空腔,在纳米载体、药物载运、新型材料等领域均具有巨大的潜在开发价值。

中亚地区是推进"一带一路"建设的重要合作区域之一,在国家推进共建"一带一路"教育行动的背景下,文章围绕中亚五国高等教育发展过程中面临的共同成就和共性挑战开展研究,以期为我国与中亚国家的高等教育的高效合作提供借鉴。研究表明,中亚国家高等教育自苏联解体以来实现了基础设施及基本框架的不断完善、教育质量保障及认证系统的从无到有及高等教育国际化的逐步加深,其教育权力运作呈现表面分散、实则集中的特点,同时存在学术研究亟需加强、教育教学手段有待更新、供求相对失衡且腐败现象亟待消除等挑战。
