Single wall carbon nanotube(SWCNT)/Si heterojunction photodetectors have the advantages of high photoresponse ability and simple structure,however,their detection wavelength range are usually lower than 1100 nm,which limits their application in the infrared *** report a SWCNT/Cu/Si photodetector with both a high photoresponse and a detection range up to the infrared band by depositing a Cu nanoparticles(NPs)layer between a SWCNT film and a n-Si *** was found that the Cu NPs produce strong surface plasmon resonance(SPR)under laser irradiation,which breaks through the limitation of Si band gap and greatly improves the photoresponse of the SWCNT/Cu/Si photodetector in the near infrared *** responsivity(R)of the photodetector in the wavelength range of 1850–1200 nm reached 2.2–14.15 mA/W,which is the highest value in the reported plasmon enhanced n-Si based photodetectors,and about 20,000 times higher than that of a SWCNT/Si *** R value for 1550 nm wavelength used in optical communications reached~8.2 mA/W,which is 64%higher than the previously reported values of commonly used *** attribute the significant increase to the strong SPR and low Schottky barrier of Cu with n-Si,which facilitates the generation and transfer of the carriers.

An Algorithm to Analyze Electron Backscatter Diffraction Data for Grain Reconstruction:from Methodology to Application

引用

Acta Metallurgica Sinica(English Letters) 2016年第5期29卷 491-499页

作者： Xue-Hao Zheng hong-wang zhang Shenyang National Laboratory for Materials Science Institute of Metal Research Chinese Academy of Sciences National Engineering Research Center for Equipment and Technology of Cold Strip Rolling College of Mechanical Engineering Yanshan University

An algorithm for grain reconstruction based on electron backscatter diffraction data was proposed in this paper. This algorithm can well record the original data arrangement when an external file for the reconstructed grain（s） was exported for further post-processing. Assisted by an in-house MATLAB program, grain reconstruction, lattice rotations, orientation spreads, and slip system analysis can be performed. The validity of this algorithm has been successfully tested by polycrystalline Ni before and after channel die compression.

探究不同有机物料投入对滨海盐碱地土壤理化性质及玉米生长发育的调控作用,为滨海盐碱地夏玉米生产提供理论依据。试验于2021-2022年夏玉米生长季在山东省滨州市无棣县滨海盐碱型农田进行。有机物料类型及用量分别为腐植酸(3000 kg hm^(–2), HA)、生物炭(15,000 kg hm^(–2), BC)、生物有机肥(15,000 kg hm^(–2), BO),以不添加有机物料为对照(CK),探究0~40 cm土层土壤容重、总孔隙度、田间持水量、pH值、电导率及总有机碳含量的变化,分析不同有机物料投入对玉米地上部干物质积累和产量形成的影响。结果表明,腐植酸、生物炭和生物有机肥的施用均可在一定程度上改善盐碱土理化性质。3种有机物料连续处理能有效降低表层土壤容重,增加土壤总孔隙度和田间持水量;可显著降低0~10cm土层pH,分别平均降低0.17、0.08和0.20。连续施用2年后,腐植酸显著降低0~40cm土层电导率,平均降低32.74%;3种有机物料显著增加0~20 cm土层中总有机碳的含量,其中生物炭处理能显著增加57.99%。腐植酸和生物有机肥处理显著增加夏玉米地上部干物质积累量和产量;连续使用2年后腐植酸处理产量显著增加了11.01%,表现较好。综上所述,本试验条件下腐植酸施用后能改善土壤物理结构、降低0~10 cm土层pH、提高土壤中有机碳含量、显著降低土壤电导率,促进夏玉米地上部干物质积累、提高籽粒产量,且连续施用2年后较CK增加纯收益。故而腐植酸可作为改良滨海盐碱地土壤理化性状、促进夏玉米生长发育的有机物料。生物有机肥的施用可改善土壤理化性状,但仍需进行定位试验以验证其长期经济效应。

研究不同类型土壤调理剂对滨海盐碱地夏玉米田0~10 cm、10~20 cm、20~30 cm和30~40 cm土层土壤盐分含量、玉米根系形态和籽粒产量的影响,为滨海盐碱地区夏玉米田适宜土壤调理剂的选用提供理论依据。试验于2022—2023年夏玉米季在山东省滨州市滨海盐碱型农田进行。采用完全随机区组设计,以不施土壤调理剂为对照(CK),设置3种不同类型的土壤调理剂,分别为硅钙钾镁型调理剂(T1)、硅钙钾镁沸石型调理剂(T2)和硅钙钾镁聚丙烯酰胺(PAM)型调理剂(T3)。研究不同类型土壤调理剂对0~40 cm土层土壤盐分含量、玉米根系形态、叶面积指数、地上部干物质积累量、氮素积累量及籽粒产量的调控效应。结果表明,与CK相比,玉米拔节期(V6)T1、T3处理20~30 cm土层土壤总盐含量和Na+含量分别降低6.88%和23.00%、28.82%和17.44%,土壤HCO3–含量分别升高10.97%、5.66%;吐丝期(R1)T2处理10~40 cm土层土壤总盐含量、Na+含量分别平均降低9.07%、14.11%,土壤HCO3–含量平均升高21.35%。土壤总盐含量降低有利于根系和地上部生长。与CK相比,吐丝期T1、T2和T3处理0~40 cm土层玉米单株平均根系长度分别提高17.56%、74.83%和33.53%;T2和T3处理单株平均根系表面积分别提高33.35%和27.44%,单株平均根系干重分别提高14.58%和11.93%。与CK相比,T1、T2和T3处理显著提高了玉米的叶面积指数,植株地上部干物质积累量以及氮素积累量,最终提高了夏玉米产量。2022年T1、T2和T3处理籽粒产量分别提高3.81%、8.22%和4.72%;2023年分别提高8.08%、18.88%和15.95%。综合分析可知,本试验条件下硅钙钾镁沸石型调理剂可有效降低玉米吐丝期土壤盐分含量,减轻盐分胁迫,促进玉米根系生长和对氮素的吸收,增加地上部氮素积累量和干物质积累量,显著增加籽粒产量,是滨海盐碱地降低盐碱胁迫促进夏玉米生长的最佳土壤调理剂类型。

In this strategy, liquid metal(LM) with a shiny metallic luster and an excellent optical property, was introduced as a novel metallic paint and coating to packing products and achieved decorative effects. We report a straightforward method via spray printing to fabricate a consecutive ultra-thin LM film on various product substrates. Then, the flexible LM film was coated with a transparent varnish layer, which was rather convenient for the LM paint to be storing, using and transporting. The thicknesses(25 μm) and the shapes of LM paint were well controlled. The flop index(FI=105), and reflectance(R=88.8%) data of the LM metallic paint were characterized. The results indicated that the LM metallic paint could provide a sparkling appearance and an abounding glossy. The deoxidized LM has a pronounced positive influence on the surface roughness, appearance, reflectance,and metallic texture. The LM metallic paint was highly desirable for potential applications in automotive enamel, motorcycle,toy and high-quality industrial coatings in the near future.

The SDIFF(T2)local-generalized Kac-Moody G(T2) symmetry is an infinite-dimensional group on the torus membrane, whose Lie algebra is the semi-direct sum of the SDIFF(T2)local algebra and the generalized KacMoody algebra g(T2). In this paper, we construct the linearly realized gauge theory of the SDIFF(T2)loc1al-generalized Kac-Moody G(T2) symmetry.

A Modified Projection Method for Linear Feasibility Problems

引用

International Journal of Automation and computing 2009年第4期6卷 401-405页

作者： Yi-Ju wang hong-Yu zhang School of Operations Research and Management Science Qufu Normal University Rizhao 276800 PRC

In this paper, we present a modified projection method for the linear feasibility problems （LFP）. Compared with the existing methods, the new method adopts a surrogate technique to obtain new iteration instead of the line search procedure with fixed stepsize. For the new method, we first show its global convergence under the condition that the solution set is nonempty, and then establish its linear convergence rate. Preliminary numerical experiments show that this method has good performance.

Use of digital subtraction angiography for assessment of digital replantation

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2012年第3期13卷 209-212页

作者： Liu-hong wang Guang-qiang zhang Department of Radiology the Second Affiliated Hospital School of Medicine Zhejiang University Hangzhou 310009 China

Objective: To assess the blood flow of the proper digital artery using digital subtraction angiography (DSA) in the early stage after replantation. Methods: From January 2006 to October 2010, 27 anastomosed arteries in 27 replanted digits were included in the study. The patients included nine males and four females. The patients received DSA at 48 to 96 h after digital replantation. Based on DSA image, the blood flow was classified into normal, slow-running, and flow-stopping types. The patients with normal digital blood flow were given continuous routine treatments; the patients with slow-running flow were given the conservative treatments, such as release of the tight dressings, removal of stitches, keeping warm, the use of massage, and the use of anticoagulants and anti-inflammatory drugs; the patients with flow-stopping received immediate surgical re-exploration. Results: In this series, 23 digits in 11 patients showed a normal blood flow, and these digits all survived. In one of 13 patients, two digits which displayed slow-running flow also survived after conservative treatments. In two of 13 patients, two digits showed flow stopping, with one surviving and one failing after re-exploration and arterial revision. Conclusions: The DSA can be used to assess the blood flow of the proper digital artery in the early stage after replantation. It provides essential information for salvaging the replanted finger.
