| 1 | Stable isotopes of summer monsoonal precipitation in southern China and the moisture sources evidence from δ^18O signature显示文摘Summer monsoons (South Asian monsoon,South China Sea monsoon and Sub-tropical monsoon) are prominent features of summertime climate over southern China. Dif-ferent monsoons carry different inflow moisture into China and control the temporal and spa-tial distributions of precipitation. Analyses of meteorological data,particularly wind,tempera-ture and pressure anomalies are traditional methods of characterizing moisture sources and transport patterns. Here,we try to utilize the evidence from stable isotopes signatures to trace summer monsoons over southern China. Based on seven CHNIP (Chinese Network of Iso-topes in Precipitation) observatory stations located in southern China,monthly composite precipitation samples have been collected and analyzed for the composition of δ18O during July,2005. The results indicated that the spatial distributions of δ18O in precipitation could properly portray the moisture sources together with their transport pathways. Moreover,the amount effect,altitude effect,temperature effect and the correlation between δ18O vs. relative humidity were discussed. | LIU Jianrong SONG Xianfang YUAN Guofu SUN Xiaomin LIU Xin WANG Zhimin WANG Shiqin | 2008 | Journal of Geographical Sciences2008，18，2： | 15 |
| 2 | Responses of Patients with Disorders of Consciousness to Habit Stimulation:A Quantitative EEG Study显示文摘Whether habit stimulation is effective in DOC patient arousal has not been reported. In this paper, we analyzed the responses of DOC patients to habit stimulation. Nineteen DOC patients with alcohol consumption or smoking habits were recruited and 64-channel EEG signals were acquired both at the resting state and at three stimulation states. Wavelet transformation and nonlinear dynamics were used to extract the features of EEG signals and four brain lobes were selected to investigate the degree of EEG response to habit stimulation. Results showed that the highest degree of EEG response was from the callname stimulation, followed by habit and music stimulations. Significant differences in EEG wavelet energy and response coefficient were found both between habit and music stimulation, and between habit and call-name stimulation. These findings prove that habit stimulation induces relatively more intense EEG responses in DOC patients than music stimulation, suggesting that it may be a relevant additional method for eliciting patient arousal. | Jingqi Li Jiamin Shen Shiqin Liu Maelig Chauvel Wenwei Yang Jian Mei Ling Lei Li Wu Jian Gao Yong Yang | 2018 | Neuroscience Bulletin2018，34，4： | 8 |

| 4 | 中国南亚热带土壤易分解有机碳和水稳性团聚体对造林的响应显示文摘造林被认为可以提高土壤碳稳定性并促进土壤碳累积。然而,实验结果差异很大,造林在提高土壤碳稳定性方面的作用仍存在争议。因此,在森林生态系统中不同土壤碳库对造林如何响应目前尚不清楚。基于此,本文对亚热带地区的尾叶桉林(Eucalyptus urophylla)、厚荚相思林(Acacia crassicarpa)、红锥林(Castanopsis hystrix)、10树种混交林和自然恢复草坡等5种不同林型的土壤碳组分进行了研究,评估其不同土层(0–10、10–20、20–40和40–60 cm)中的土壤易分解有机碳(容易被高锰酸钾氧化的有机碳ROC和土壤可溶性有机碳DOC)及土壤团聚体相关的碳对造林的响应。实验结果表明,造林(与自然恢复草坡比较)和林型并没有显著影响土壤ROC浓度,而自然恢复草坡土壤的DOC浓度在4个土层中均最高。0–10 cm土层中各径级的土壤团聚体其碳(C)浓度均是红锥林最高。此外,在任一土层中,林型对不同径级土壤水稳性团聚体比例的影响均不显著。但是土壤深度显著改变土壤团聚体的分布,0–20 cm土层主要为>0.25 mm粒径的团聚体,20–60 cm土层则是0.053–2 mm粒径的团聚体占主导。这些结果显示造林和林型影响土壤DOC和团聚体C,而且它们相比于ROC对造林的响应更为敏感。研究发现,与自然恢复相比,人工林降低了土壤DOC浓度,暗示它可能会减少土壤C的淋溶损失。此外,红锥林能够通过物理保护提高表土层中土壤碳的稳定性。本研究为关注土壤碳汇功能时的中国南亚热带地区造林树种选择提供了有价值的信息。 | Yuanqi Chen Yu Zhang Shiqin Yu Feng Li Suping Liu Lixia Zhou Shenglei Fu | 2021 | Journal of Plant Ecology2021，14，2： | 2 |
| 5 | Bamboo-inspired cell-scale assembly for energy device applications显示文摘Rapid advances in flexible and wearable smart textiles demand low-cost,high-energy/power-density fiber-shaped supercapacitors(FSCs).The performance of FSCs is determined by the fabrication and assembly of fiber-shaped electrodes(FSEs),where an active charge-storage material is always clad around flexible charge transmission current collectors.Inspired by the tissue structure of natural bamboo,wherein parenchyma cells(PCs)that store nutrients are clad around bamboo fibers(BFs),we propose a strategy for converting bamboo cells into FSEs using conductive BFs and activated PCs as current collectors and active materials,respectively.The assembled electrode has a high specific capacitance of 1454 mF cm^(−2) at 0.64 mA cm^(−2).A solid-state FSC with a pair of bamboo-structured electrodes exhibited a substantially high energy density.Its mechanical flexibility enabled the knitting of wearable wristbands to drive ultra-small voltmeter indicators.This lightweight,low cost,and high-energy-density bamboostructured FSC could enable numerous smart textile applications. | Qiuqin Lin Runan Gao Daohao Li Yun Lu Shiqin Liu Yanglun Yu Yuxiang Huang Wenji Yu | 2022 | npj Flexible Electronics2022，6，1： | 1 |
| 6 | Genomic analysis,trajectory tracking,and field surveys reveal sources and long-distance dispersal routes of wheat stripe rust pathogen in China显示文摘Identifying sources of phytopathogen inoculum and determining their contributions to disease outbreaks are essential for predicting disease development and establishing control strategies.Puccinia striiformis f.sp.tritici(Pst),the causal agent of wheat stripe rust,is an airborne fungal pathogen with rapid virulence variation that threatens wheat production through its long-distance migration.Because of wide variation in geographic features,climatic conditions,and wheat production systems,Pst sources and related dispersal routes in China are largely unclear.In the present study,we performed genomic analyses of 154 Pst isolates from all major wheat-growing regions in China to determine Pst population structure and diversity.Through trajectory tracking,historical migration studies,genetic introgression analyses,and field surveys,we investigated Pst sources and their contributions to wheat stripe rust epidemics.We identified Longnan,the Himalayan region,and the Guizhou Plateau,which contain the highest population genetic diversities,as the Pst sources in China.Pst from Longnan disseminates mainly to eastern Liupan Mountain,the Sichuan Basin,and eastern Qinghai;that from the Himalayan region spreads mainly to the Sichuan Basin and eastern Qinghai;and that from the Guizhou Plateau migrates mainly to the Sichuan Basin and the Central Plain.These findings improve our current understanding of wheat stripe rust epidemics in China and emphasize the need for managing stripe rust on a national scale. | Yuxiang Li Jichen Dai Taixue Zhang Baotong Wang Siyue Zhang Conghao Wang Jiguang Zhang Qiang Yao Mingju Li Chengyun Li Yuelin Peng Shiqin Cao Gangming Zhan Fei Tao Haifeng Gao Weili Huang Xiaojun Feng Yingwen Bai Zhuoma Qucuo Hongsheng Shang Chong Huang Wancai Liu Jiasui Zhan Xiangming Xu Xianming Chen Zhensheng Kang Xiaoping Hu | 2023 | Plant Communications2023，4，4： | 1 |
| 7 | Parallel generation of low-correlation wideband complex chaotic signals using CW laser and external-cavity laser with self-phase-modulated injection显示文摘A novel scheme for generating optical chaos is proposed and experimentally demonstrated,which supports to simultaneously produce two low-correlation chaotic signals with wideband spectrum and suppressed time-delay-signature(TDS).In the proposed scheme,we use the output of an external-cavity semiconductor laser(ECSL)as the driving signal of a phase modulator to modulate the output of a CW laser.Then the phase-modulated continuous-wave(CW)light is split into two parts,one is injected back into the ECSL that outputs one chaotic signal,while the other part is passed through a dispersion module for generating another chaotic signal simultaneously.The experimental results prove that the proposed scheme has three merits.Firstly,it can improve the bandwidth of ECSL-based chaos by several times,and simultaneously generate another wideband flat-spectrum chaotic signal.Secondly,the undesired TDS characteristics of the simultaneously-generated chaotic signals can be efficiently suppressed to an indistinguishable level within a wide parameter range,as such the complexities of the chaotic signals are considerably high.Thirdly,the correlation coefficient between these two simultaneously-generated chaotic signals is smaller than 0.1.The proposed scheme provides an attractive solution for parallel multiple chaos generation,and shows great potential for multiple channel chaos communications and multiple random bit generations. | Anke Zhao Ning Jiang Jiafa Peng Shiqin Liu Yiqun Zhang Kun Qiu | 2022 | Opto-Electronic Advances2022，5，5： | 1 |
| 8 | Anomalies in Water Level Records in Yunnan Caused by the Great Indonesian Earthquakes and Their Significance显示文摘Two great earthquakes occurred in the sea northwest of Sumatra,Indonesia,on December 26,2004 and March 29,2005.The observation of water levels in Yunnan yielded abundant information about the two earthquakes.This paper presents the water level response to the two earthquakes in Yunnan and makes a preliminary analysis.It is observed that the large earthquake-induced abnormal water level change could be better recorded by analog recording than by digital recording.The large earthquake-caused water level rise or decline may be attributed to the effect of seismic waves that change the stress in tectonic units,and is correlated with the geological structure where the well is located.The water level response mode in a well is totally the same for earthquakes occurring on the same fault and with the same fracture mode.The only difference is that the response amplitude increases with the growth of the earthquake magnitude. | Fu Hong Wu Chengdong Liu Qiang Wang Shiqin Chen Yan | 2008 | Earthquake Research in China2008，22，4： | 0 |
| 9 | Rare Earth Elements in Manganese Nodules from the Central Pacific Ocean显示文摘Manganese nodules in areas CP and CC of the central Pacific are rich in REE. Comparatively speaking,the REE contents of nodules in area CP are hihger than those in area CC; and the REE contents of nodulesfrom seamounts are higher than those of nodules from sea-floor plains and hills. Within the nodules, the REEshow a zonal distribution. The REE distribution patterns of the nodules are similar to those of the sedimentsand have a mirror image relationship with those of the sea water. Trivalent REE were not obviously differenti-ated when they entered into the nodules from the sea water.A major factor causing the difference of REE abundances between nodules and sediments is the redoxconditions. The redox intensity of the ocean floor of the Pacific is controlled mainly by Antarctic Bottom Wat-er(AABW), The iron-bearing facies in the nodules is the main carrier of REE. | Guo Shiqin Sun Wenhong China Ocean Mineral Resources Research and Developmetn Association Institute of Mineral Deposits, Chinese Academy of Geological Sciences Liu Linqun | 1992 | Acta Geologica Sinica(English Edition)1992，66，4： | 0 |
| 10 | Enhanced production of L-sorbose by systematic engineering of dehydrogenases in Gluconobacter oxydans显示文摘L-Sorbose is an essential intermediate for the industrial production of vitamin C(L-ascorbic acid).However,the formation of fructose and some unknown by-products significantly reduces the conversion ratio of D-sorbitol to L-sorbose.This study aimed to identify the key D-sorbitol dehydrogenases in Gluconobacter oxydans WSH-003 by gene knockout.Then,a total of 38 dehydrogenases were knocked out in G.oxydans WSH-003,and 23 dehydrogenase-deficient strains could increase L-sorbose production.G.oxydans-30,wherein a pyrroloquinoline quinone-dependent glucose dehydrogenase was deleted,showed a significant reduction of a by-product with the extension of fermentation time.In addition,the highest conversion ratio of 99.60%was achieved in G.oxydans MD-16,in which 16 different types of dehydrogenases were inactivated consecutively.Finally,the gene vhb encoding hemoglobin was introduced into the strain.The titer of L-sorbose was 298.61 g/L in a 5-L bioreactor.The results showed that the systematic engineering of dehydrogenase could significantly enhance the production of L-sorbose. | Li Liu Yue Chen Shiqin Yu Jian Chen Jingwen Zhou | 2022 | Synthetic and Systems Biotechnology2022，7，2： | 0 |
| 11 | A Preliminary Study on Ultrasonic Cutting Process for Carbon Fibre Prepreg显示文摘In ultrasonic cutting process, the cutting pressure is still essential for achieving good quality cut edge compared with traditional mechanical cutting process. With the increase of the cutting power, the cutting pressure demand decreases. The cutting velocity range is extended broadly. The experiment results show that ultrasonic cutting technique is an effective, clean and controllable method for machining of carbon fibre prepreg. | Jingquan LIU Jiuchun YAN Shiqin YANG | 2001 | Journal of Materials Science & Technology2001，17，1： | 0 |
| 12 | Effects of molten state of ultrasonic welded Joints of plastics on their strength显示文摘Effects of molten state of ultrasonic welded joints of plastics on their strength were investigated. Physical parameters such as temperature, viscosity and thickness of melting layers of plastic material joints were measured and analyzed. Results show that when the welding vibration amplitude and pressure increase, the temperature increases, the viscosity decreases, and the thickness of molten layer decreases. The microstructure of weld fusion zone was observed by using an optical microscope. It was found that there is strong orientation along transverse direction in the microstructure of fusion zone. Testing results show that the mechanics performance of welded joints are obviously anisotropic, and strongly affected by the thickness of molten layer and the extent of orientation. | YAN Jiuchun, LIU Jingquan, ZHOU Yusheng, YANG Shiqin (National Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology Harbin 150001) ZHOU Fuhong (Department of Underwater Acoustics Engineering, Harbin Institute of Enginee | 2001 | Chinese Journal of Acoustics2001，20，4： | 0 |
| 13 | Sedimentary elements,evolutions and controlling factors of the Miocene channel system:a case study of the deep-water Taranaki Basin in New Zealand显示文摘Deep-water channel systems are important petroleum reservoirs,and many have been discovered worldwide.Understanding deep-water channel sedimentary elements and evolution is helpful for deep-sea petroleum exploration and development.Based on high-resolution 3D seismic data,the Miocene channel system in the deep-water Taranaki Basin,New Zealand,was analyzed by using seismic interpretation techniques such as interlayer attribute extraction and strata slicing.The channel system was divided into five composite channels(CC-I to CC-V)according to four secondary level channel boundaries,and sedimentary elements such as channels,slump deposits,inner levees,mass transport deposits,and hemipelagic drape deposits were identified in the channel system.The morphological characteristics of several composite channels exhibited stark variances,and the overall morphology of the composite channels changed from relatively straight to highly sinuous to relatively straight.The evolution of the composite channels involved a gradual and repeated process of erosion and filling,and the composite channels could be divided into three evolutionary stages:initial erosion-filling,later erosion-filling(multistage),and channel abandonment.The middle Miocene channel system may have formed as a consequence of combined regional tectonic activity and global climatic change,and its intricate morphological alterations may have been influenced by the channel's ability to self-regulate and gravity flow properties.When studying the sedimentary evolution of a large-scale deep-water channel system in the Taranaki Basin during the Oligocene-Miocene,which transitioned from a passive margin to plate convergence,it can be understood how tectonic activity affected the channel and can also provide a theoretical reference for the evolution of the deepwater channels in areas with similar tectonic conversion environments around the world. | Guangxu Wang Wei Wu Changsong Lin Quan Li Xiaoming Zhao Yongsheng Zhou Weiqing Liu Shiqin Liang | 2023 | Acta Oceanologica Sinica2023，42，11： | 0 |
