| 1 | Soil microbial properties under different vegetation types on Mountain Han显示文摘This study investigated the influence of broadleaf and conifer vegetation on soil microbial communities in a distinct vertical distribution belt in Northeast China.Soil samples were taken at 0-5,5-10 and 10-20 cm depths from four vegetation types at different altitudes,which were characterized by poplar(Populus davidiana)(1250-1300 m),poplar(P.davidiana) mixed with birch(Betula platyphylla)(1370-1550 m),birch(B.platyphylla)(1550-1720 m),and larch(Larix principis-rupprechtii)(1840-1890 m).Microbial biomass and community structure were determined using the fumigation-extraction method and phospholipid fatty acid(PLFA) analysis,and soil fungal community level physiological profiles(CLPP) were characterized using Biolog FF Microplates.It was found that soil properties,especially soil organic carbon and water content,contributed significantly to the variations in soil microbes.With increasing soil depth,the soil microbial biomass,fungal biomass,and fungal catabolic ability diminished;however,the ratio of fungi to bacteria increased.The fungal ratio was higher under larch forests compared to that under poplar,birch,and their mixed forests,although the soil microbial biomass was lower.The direct contribution of vegetation types to the soil microbial community variation was 12%.If the indirect contribution through soil organic carbon was included,variations in the vegetation type had substantial influences on soil microbial composition and diversity. | WANG Miao QU LaiYe MA KeMing YUAN Xiu | 2013 | Science China(Life Sciences)2013，56，6： | 10 |

| 3 | Power flows of three non-conservatively series-coupled oscillators, Part Ⅱ: Numerical analysis显示文摘The direct and indirect power flows among three non-conservatively series-coupled oscillators subjected to random forces have been investigated by the numerical method. The relationship between the power flows and the parameters of the oscillators and couplings have been studied. It is shown that the indirect power flow is caused by the resonant transmission between the indirectly coupled oscillators. Once the parameters of the oscillator elements have been settled, the indirect power flow is mainly determined by the coupling stiffness k3 and k4, and is less infiuenced by coupling dampings c3 and c4. The indirect power flow cannot be ignored in strong coupling conditions. Because of the resonant transmission between the indirectly coupled oscillators, the indirect power flow still cannot be neglected even if the coupling stiffness is relatively small and the coupling damping is relatively | WANG Minqing(Xi’an Jiaotong University Xi’an 710049)SHENG Meiping Ren Keming SUN Jincai(Institute of Acoustics Engineering, Northwestern Polgtechnical University Xi’an 710072) | 1998 | Chinese Journal of Acoustics1998，17，3： | 4 |

| 5 | Selective feeding of bay scallop Argopecten irradians on phytoplankton community revealed by HPLC analysis of phytopigments in Bohai Sea, China显示文摘Understanding the feeding selectivity on phytoplankton by shellfi sh is currently a big challenge. In order to investigate the feeding behavior of bay scallop ( Argopecten irradians ) on phytoplankton, we compared its compositions of phytopigments in digestive glands with those in the surrounding seawater, and conducted fi ve consecutive investigations between July and November 2016 in a bay scallop culture area along coast of Qinghuangdao City, northwest of the Bohai Sea, China. Phytopigments in four-size fractionated phytoplankton of seawater (micro-(20-200 μm);nano(L)-[10-20 μm];nano(S)-[2.7-10 μm], and pico-[<2.7 μm]) and digestive glands of A . irradians were examined to investigate the selective feeding of A . irradians . Results show that fucoxanthin and peridinin constituted the major part of taxonomically diagnostic carotenoids (TDCs) in the micro- and nano(L)-phytoplankton in seawater. Compared with total phytoplankton biomass of seawater (TPB, sum of the four sizes), a substantial decrease of fucoxanthin proportion to total DCs in digestive glands was observed while that of peridinin, 19′-butanoyloxyfucoxanthin, alloxanthin and 19′-hexanoyloxy-fucoxanthin showed an obvious increase when those pigments were mainly confi ned to micro-sized phytoplankton (20-200 μm). However, zeaxanthin and prasinoxanthin were mainly confi ned to nano(s)- and pico-phytoplankton, of which the proportions in digestive glands were usually lower in TPB. The contribution of lutein to total DCs in digestive glands (with an average of 7.23%) increased compared with TPB of seawater (with an average of 0.63%) during all fi ve sampling times. | JIANG Tao WANG Longhua ZHANG Fuchong FANG Xiao LU Lin ZHANG Jihong WANG Wei QU Keming CHAI Chao | 2019 | Journal of Oceanology and Limnology2019，37，5： | 4 |
| 6 | Effects of plant coverage on shrub fertile islands in the Upper Minjiang River Valley显示文摘The patchy distribution of vegetation in dry land results in well-documented 'fertile islands'. However, the response of shrub fertile islands to plant recovery and the underlying mechanisms, such as the linkage plant and soil properties, remain unknown.We sampled soils from areas with three different plant coverages(25%, 45%, and 75%) and three of their adjacent inter-plants to investigate soil physicochemical and microbial properties in the upper Minjiang River arid valley. The results showed that these factors were influenced by the persistence of plants that contrasted with the inter-plant interspaces. We found fertile islands in under-plant soil that were enhanced with increasing plant coverage, from 25% to 45% and 75%; however, there were no significant differences between 45% and 75% plant coverage apart from the soil clay content and the fungi to bacteria ratio. The soil microbial communities in under-plant soil were strongly influenced by the total soil carbon(TC), soil organic carbon(SOC),and available nitrogen(AN), whereas the microbial communities in inter-plant soil were primarily constrained by the AN and available phosphorous(AP). Moreover, the inter-plant soil properties, including gravimetric soil water content, pH, electrical conductivity(EC), and soil C:N ratio, were also strongly influenced by adjacent vegetation, which suggested that fertile islands may be beneficial for plant recovery in this region. | Laiye Qu Zhongbin Wang Yuanyuan Huang Yuxin Zhang Chengjun Song Keming Ma | 2018 | Science China(Life Sciences)2018，61，3： | 3 |
| 7 | Analysis of single frequency modulation for passive hydrogen maser显示文摘Based on the theory of the passive hydrogen maser,along with the technology of frequency modulation and modulation transfer spectroscopy, the theoretical expression of the single frequency modulation for the passive hydrogen maser and the function of the cavity and H line error signals separation are derived, which are basically coincident with the experiment. The absorption and dispersion spectrum curves with different resonance widths show that the cavity and hydrogen transition serve as discriminators, and the two error signals can be separated.Through the calculations of the two error signals in the passive hydrogen maser, it analyzes the traditional method of the two error signals separation, and then describes a new improved method for the passive hydrogen servo loops consisting in the use of a single modulation frequency and frequency discrimination. A null interaction of the two error signals for the new selection of the phase setting is deduced theoretically and validated by the simulation.The preliminary experimental result confirms the feasibility of this new approach, which can reduce the influence from the cavity frequency variety on the crystal oscillator and contribute significantly to the long term performance of the passive hydrogen maser. | Hefei Zheng Jing Li Wenming Wang Lianshan Gao Keming Feng | 2017 | Journal of Systems Engineering and Electronics2017，28，4： | 2 |
| 8 | Hydrocarbon Generation and Expulsion of the Upper Triassic T3x5Source Rocks in the Western Sichuan Depression: Assessment for Unconventional Natural Gas显示文摘Tight-sand gas in the Jurassic and shale gas within the fifth member of Xujiahe Formation(T3x5) in the Western Sichuan Basin(WSD) are currently regarded as the most prolific emerging unconventional gas plays in China. This study conducted a conventional evaluation of T3x5 source rocks in the WSD, and investigated their hydrocarbon generation and expulsion characteristics, including intensity, efficiency and amount. The results show that, the T3x5 source rocks are thick(generally >200 m), and have a high total organic content(TOC), ranging from 2.5 to 4.5 wt%. It is thus indivative of a great hydrocarbon generation potential when they underwent high thermal evolution(Ro>1.2%) in the area. In addition, an improved method of hydrocarbon generation potential is applied, indicating that the source rocks reached a hydrocarbon expulsion threshold with vitrinite reflectance(Ro) reaching 1.06%, and that the comprehensive hydrocarbon expulsion efficiency is about 60%. The amount of hydrocarbon generation and expulsion from T3x5 source rocks is 3.14×1010 t and 1.86×1010 t, respectively, with a residual amount of 1.28×1010 t within them. Continuous-type tight-sand gas is predicted to have developed in the Jurassic in the Chengdu Sag of the WSD because of the good source-reservoir configuration; the Jurassic sandstone reservoirs are tight, and the gas expelled from the T3x5 source rocks migrates for very short distances vertically and horizontally. The amount of gas accumulation in the Jurassic reservoirs derived from T3x5 source rocks is up to 9.3×108 t. Geological resources of shale gas are up to 1.05×1010 t. Small differences between the amounts calculated by the volumetric method and those obtained by hydrocarbon generation potential method may be due to other gas accumulations present within interbedded sands associated with gas shales. | GUO Yingchun SONG Yan PANG Xiongqi WANG Youwei YANG Keming LI Boyuan | 2015 | Acta Geologica Sinica(English Edition)2015，89，1： | 2 |
| 9 | Partitioning the effects of environmental and spatial heterogeneity on distribution of plant diversity in the Yellow River Estuary显示文摘For successful conservation and restoration of biodiversity,it is important to understand how diversity is regulated.In the ecological research community,a current topic of interest is how much of the variation in plant species richness and composition is explained by environmental variation(niche-based model),relative to spatial processes(neutral theory).The Yellow River Estuary(YRE) is a newly formed and fragile wetland ecosystem influenced by both the Yellow River and Bohai Bay.Here,we applied variance partitioning techniques to assess the relative effects of spatial and environmental variables on species richness and composition in the YRE.We also conducted a species indicator analysis to identify characteristic species for three subestuaries within the YRE.Partial redundancy analysis showed that the variations in species richness and composition were explained by both environmental and spatial factors.The majority of explained variation in species richness and composition was attributable to local environmental factors.Among the environmental variables,soil salinity made the greatest contribution to species abundance and composition.Soil salinity was the most important factor in the Diaokou subestuary,while soil moisture was the most important factor influencing species richness in the Qingshui and Chahe subestuaries.The combined effects of soil salinity and moisture determined species richness and composition in the wetlands.These results increase our understanding of the organization and assembly of estuarine plant communities. | YUAN Xiu MA KeMing WANG De | 2012 | Science China(Life Sciences)2012，55，6： | 2 |

| 13 | MXene-GaN van der Waals metal-semiconductor junctions for high performance multiple quantum well photodetectors显示文摘A MXene-GaN-MXene based multiple quantum well photodetector was prepared on patterned sapphire substrate by facile drop casting.The use of MXene electrodes improves the responsivity and reduces dark current,compared with traditional Metal-Semiconductor-Metal(MSM)photodetectors using Cr/Au electrodes.Dark current of the device using MXene-GaN van der Waals junctions is reduced by three orders of magnitude and its noise spectral intensity shows distinct improvement compared with the traditional Cr/Au–GaN–Cr/Au MSM photodetector.The improved device performance is attributed to low-defect MXene-GaN van der Waals interfaces.Thanks to the high quality MXene-GaN interfaces,it is possible to verify that the patterned substrate can locally improve both light extraction and photocurrent collection.The measured responsivity and specific detectivity reach as high as 64.6 A/W and 1.93×1012 Jones,respectively,making it a potential candidate for underwater optical detection and communication.The simple fabrication of MXene-GaN-MXene photodetectors spearheaded the way to high performance photodetection by combining the advantages of emerging 2D MXene materials with the conventional III-V materials. | Lingzhi Luo Yixuan Huang Keming Cheng Abdullah Alhassan Mahdi Alqahtani Libin Tang Zhiming Wang Jiang Wu | 2021 | Light(Science & Applications)2021，10，10： | 1 |
