| 2 | Fabrication of ZnS/CdS Heterojunction by Using Bimetallic MOFs Template for Photocatalytic Hydrogen Generation显示文摘A new ZnS/CdS heterojunction is constructed through the direct sulfurization of a metal ions exchanged Zn/Cd-MOF precursor(MOF=metal-organic framework material).The composition,structure,morphology,photoabsorption and photoelectric performance of the ZnS/CdS are characterized by powder X-ray diffraction(PXRD),scanning electron microscope(SEM),transmission electron microscope(TEM),diffuse reflection spectrum(DRS),photoelectric current(PEC),electrochemical impedance spectroscopy(El S)and photoluminescence(PL)technologies.Since the metal ions are highly orderly separated by the organic ligands and the inherent porosity of the Zn/Cd-MOF,the as-synthesized ZnS/CdS possesses a large surface area and intimate contact at the heterogeneous interface with uniform ZnS/CdS nanoparticles.The photocatalytic hydrogen evolution activity of the ZnS/CdS is investigated under visible light irradiation(A^420 nm).It exhibits enhanced photocatalytic performance that the optimal ZnS/CdS achieves a maximum average hydrogen production rate of 2348μmol·h^-1 g^-1.A possible electron transfer mechanism is therefore proposed by the analyses of the Mott-Schottky plots. | ZHU Yuxin JIANG Xing LIN Lin WANG Shuhua CHEN Chao | 2020 | Chemical Research in Chinese Universities2020，36，6： | 2 |
| 3 | Validity and Accuracy of Eddy Current Field Analysis of Laminations by Introducing Equivalent Conductivities显示文摘对于分析叠片铁心中的涡流问题,利用各种等效电导率替代硅钢片实际电导率的匀质化方法是很有应用前景的。为了评估各种电导率模型,该文提出了铁心涡流场分析的二维解析验证方法,并分别基于引入各向异性或各向同性等效电导率的铁心连续体表述和实际叠片表述对涡流场进行了解析计算。通过比较连续体表述下所得到的平均磁通密度和涡流损耗值与相应由实际叠片表述所得到的精确解,对各种电导率模型的有效性和准确性在各种条件下进行了评估。为了进一步考察电导率模型对实际工程问题的适用性,利用有限元法进行了关于TEAM21面向工程基准问题的磁通和杂散场损耗计算。计算结果表明,由该文作者所提出的等效电导率模型优于其他模型。 | WANG Jian LIN Heyun FANG Shuhua HUANG Yunkai | 2012 | 中国电机工程学报2012，32，27： | 2 |

| 13 | The Surface Energy Budget and Its Impact on the Freeze-thaw Processes of Active Layer in Permafrost Regions of the Qinghai-Tibetan Plateau显示文摘The surface energy budget is closely related to freeze-thaw processes and is also a key issue for land surface process research in permafrost regions.In this study,in situ data collected from 2005 to 2015 at the Tanggula site were used to analyze surface energy regimes,the interaction between surface energy budget and freeze-thaw processes.The results confirmed that surface energy flux in the permafrost region of the Qinghai-Tibetan Plateau exhibited obvious seasonal variations.Annual average net radiation(R_(n))for 2010 was 86.5 W m^(-2),with the largest being in July and smallest in November.Surface soil heat flux(G_(0))was positive during warm seasons but negative in cold seasons with annual average value of 2.7 W m^(-2).Variations in R_(n) and G_(0) were closely related to freeze-thaw processes.Sensible heat flux(H)was the main energy budget component during cold seasons,whereas latent heat flux(LE)dominated surface energy distribution in warm seasons.Freeze-thaw processes,snow cover,precipitation,and surface conditions were important influence factors for surface energy flux.Albedo was strongly dependent on soil moisture content and ground surface state,increasing significantly when land surface was covered with deep snow,and exhibited negative correlation with surface soil moisture content.Energy variation was significantly related to active layer thaw depth.Soil heat balance coefficient K was>1 during the investigation time period,indicating the permafrost in the Tanggula area tended to degrade. | Junjie MA Ren LI Hongchao LIU Zhongwei HUANG Tonghua WU Guojie HU Yao XIAO Lin ZHAO Yizhen DU Shuhua YANG | 2022 | Advances in Atmospheric Sciences2022，39，1： | 1 |
