采用离子注入的金属有机化学汽相淀积（mOCVD）缓冲层制作了低噪声GaAs金属-半导体场效应晶体管（mESFET）。在12GHz下,0.5μm（栅长）×300μm（栅宽）的FET器件的噪声系数可达1.46dB,相关增益达到10.20dB。此结果证明,采用离子注入mO... 详细信息

采用离子注入的金属有机化学汽相淀积（mOCVD）缓冲层制作了低噪声GaAs金属-半导体场效应晶体管（mESFET）。在12GHz下,0.5μm（栅长）×300μm（栅宽）的FET器件的噪声系数可达1.46dB,相关增益达到10.20dB。此结果证明,采用离子注入mOCVD缓冲层能制成极好的GaAs LNFET,它可以与采用AsCl;汽相外延和分子束外延制作的类似器件所得的最佳结果相比拟。

XPS Study on the Dimethyl-modified Silica Xerogel

第三十五届国际光谱会议

作者： J.Huang C.Zheng m.feng H.B.Zhan~* College of materials Science and Engineering Fuzhou University Fuzhou 350002 China

＜正＞Silver nanoparticles have attracted great attentions because of their potential applications of catalysis,biological labeling,information storage,surface enhanced Raman scattering （SERS）,photography,photonics,and optoelectronic[1-3].Silver nanoparticles have been known to possess large nonlinear optical properties and ultrafast response times[4]. However,to our knowledge,seldom studies have focused on the optical limiting property

本篇文章对常温及均匀高温条件下的冷成型薄壁短槽钢的轴向强度进行了初步研究。对常温及均匀高温下的一系列卷边的或非卷边的槽钢进行了试验研究。应用一系列的设计方法和商业化的有限元软件ABAQUS( 1998)对试验进行了分析。本文中涉及的设计方法包括 :英国规范BS5 95 0 ( 1987)、欧洲规范Eurocode 3Part1.3 (CEN1996)和美国规范AISI( 1996) ,在有限元分析中 ,考虑了几何非线性和材料非线性。高温下钢材的应力 -应变曲线根据欧洲规范Eurocode 3Part 1.2(CEN1995 )和Qutinen ( 2 0 0 1)采用。在某些试验中发现扭转屈曲 ,为了扩展针对这种破坏模式的设计方法 ,在这些规范中引用了Yong和Hancock( 1992 )考虑扭转屈曲的方法。对设计规范BS5 95 0Part 5 ( 1987)、欧洲规范Eurocode 3Part 1.3(CEN1996)和美国规范AISI( 1996)中常温下薄壁柱的设计方法加以修改 ,来考虑钢材高温下的强度和刚度的变化。从试验结果、规范预期的结果和数值分析的比较可见。

We are interested in investigating whether cancer therapy may alter the mitochondrial redox state in cancer cells to inhibit their growth and *** redox state can be imaged by the redox scanner that collects the fuorescence signals from both the oxidized-fAavoproteins(Fp)and the reduced form of nicotinamide adenine dinucleotide(NADH)in snap frozen tissues and has been previously employed to study tumor aggressiveness and treatment ***,with the redox scanner we investigated the effects of chemotherapy on mouse xenografts of a human diffuse large *** lymphoma cell line(DLCL2).The mice were treated with CHOP therapy,i.e,cyclophosphamide(C)+hydroxydoxorubicin(H)+Oncovin(O)+prednisone(P)with CHO administration on day 1 and prednisone administration on days *** Fp content of the treated group was significantly decreased(p=0.033)on day 5,and the mitochondrial redox state of the treated group was slightly more reduced than that of the control group(p=0.048).The decrease of the Fp heterogeneity(measured by the mean st andard deviation)had a border-line statistical significance(p=0.071).The result suggests that the mitochondrial metabolism of lymphoma cells was slightly suppressed and the lymphomas became less aggressive after the CHOP therapy.
