| 1 | Effects of Water and Nitrogen Supply on Spinach(Spinacia oleracea L.) Growth and Soil Mineral N Residues显示文摘Effects of conventional and optimized water and nitrogen managements on spinach (Spinacia olerocea L.)growth and soil mineral N (Nmi.) residues were compared in an open field experiment in which water balancemethod and N recommendation with the KNS-system were included. It was shown that the conventionalwater treatment (seasonal irrigated amount: 175 mm) reduced spinach growth compared to the water balancetreatments (seasonal irrigated amount: 80 and 85 mm) at the same N supply level due to N loss throughleaching caused by excessive water supply. Although 309 kg N ha-1 was applied in the conventional Ntreatment, compared to 82 and 66 kg N ha-l in the optimum N treatments, no significant difference in cropyield was investigated between the N treatments with the same irrigation practice. N uptake in spinach andsoil residual Nmin contents were also significantly affected by the irrigation practices. The conventional watersupply not only decreased water use efficiency, but also | CHENQING H.P.LIEBIG 等 | 2002 | Pedosphere2002，12，2： | 18 |

| 3 | Estimating significant wave height from SAR imagery based on an SVM regression model显示文摘A new method for estimating significant wave height(SWH) from advanced synthetic aperture radar(ASAR) wave mode data based on a support vector machine(SVM) regression model is presented. The model is established based on a nonlinear relationship between σ0, the variance of the normalized SAR image, SAR image spectrum spectral decomposition parameters and ocean wave SWH. The feature parameters of the SAR images are the input parameters of the SVM regression model, and the SWH provided by the European Centre for Medium-range Weather Forecasts(ECMWF) is the output parameter. On the basis of ASAR matching data set, a particle swarm optimization(PSO) algorithm is used to optimize the input kernel parameters of the SVM regression model and to establish the SVM model. The SWH estimation results yielded by this model are compared with the ECMWF reanalysis data and the buoy data. The RMSE values of the SWH are 0.34 and 0.48 m, and the correlation coefficient is 0.94 and 0.81, respectively. The results show that the SVM regression model is an effective method for estimating the SWH from the SAR data. The advantage of this model is that SAR data may serve as an independent data source for retrieving the SWH, which can avoid the complicated solution process associated with wave spectra. | GAO Dong LIU Yongxin MENG Junmin JIA Yongjun FAN Chenqing | 2018 | Acta Oceanologica Sinica2018，37，3： | 7 |

| 5 | Auditory characteristics of noise-exposed memberscrossing age-related groups显示文摘Objective: To report audiological characteristics in a group of noise-exposed crew members on board ships.Methods and materials: Clinical and audiological measurements including pure-tone thresholds, acoustic immittance results and tinnitus questionnaires were collected from both the ship crew members(study subjects) and their land based colleagues(controls).Results: 1) Noise exposed crew members showed not only high frequency, but also low frequency hearing loss; 2) Hearing impairment increased with age, with 65.5% of crew members younger than 50 years showing normal hearing while only 14.9% of those older than 50 years had normal hearing; 3)hearing loss gradually increased with the extension of on board career time; and 4) Most study subjects reported high pitch tinnitus, significantly more than the control group although not significantly different among different age groups.Conclusion: Noise induced hearing impairment from working on board ships shows specific frequency and age characteristics. Understanding these characteristics is important for advancing relevant studies and for effective prevention of noise-induced hearing loss in ship crew members. | Liu Chenqing Ding Daxiong Zhu Yuhua Wang Hongyang Cheng Xiaoting Zhao Zhenhua Cao Juyang Zhai Suoqiang Yu Ning | 2018 | Journal of Otology2018，13，2： | 3 |
| 6 | Observation of internal waves with OLCI and SRAL on board Sentinel-3显示文摘The ocean and land color instrument(OLCI) and synthetic aperture radar altimeter(SRAL) installed aboard the Sentinel-3 satellite have been in orbit for operational uses. In this study, data collected from Sentinel-3 are used to investigate internal waves in the South China Sea. An internal wave is detected using an OLCI image with a resolution of 300 m, and an analysis was performed with a quasi-synchronous moderate-resolution imaging spectroradiometer(MODIS) image. The opposite characteristics of OLCI and MODIS images of the same internal wave are explained by the critical angle in brightness reversals. The unique observational geometry of the OLCI image and its influence on observations of internal waves are discussed. The distribution of σ0 and sea surface height anomalies(SSHAs) induced by internal waves are studied using SRAL records. The σ0 records of SRAL occasionally show less sensitivity to the modulation of internal waves, which may be attributed to the observational geometry, while SSHAs show obvious variations. The synchronous pairing of OLCI images and SRAL records are analyzed to extract the three-dimensional sea surface signatures induced by internal waves. The analysis demonstrates that the profile of SSHAs in the surface shows an opposite phase to the profiles of internal waves in the ocean. The opposite phase relationship, observed in the remote sensing view, is also confirmed with a laboratory experiment. | Xudong Zhang Jie Zhang Junmin Meng Chenqing Fan Jing Wang | 2020 | Acta Oceanologica Sinica2020，39，3： | 2 |
| 7 | FTIR Spectroscopy in Cultural Heritage Studies: Non-destructive Analysis of Chinese Handmade Papers显示文摘Chinese handmade papers have been the carriers of paper-based documents, paintings and calligraphies, which are of great importance for historical and cultural heritage studies. This research developed the attenuated total reflectance-Fourier transform infrared(ATR-FTIR) spectroscopic technique for the analysis of Chinese handmade papers. The test was applied to Chinese handmade papers taken from bark, hemp and bamboo groups, followed by papers from ancient books and arts collected in library and museum. Our study indicated tliat FTIR was an efficient analytical method to identify fiber types of library/museum papers of unknown origin. Moreover, information about degree of crystallinity and state of deterioration of cellulosic fibers was learned from FTIR spectra. This research provides a non-destnictive method to study the molecular structure of cellulosic fibers, and guides tlie selection of appropriate Chinese handmade papers for the restoration of cultural heritage objects. | YAN Yueer WEN Chenqing JIN Ming DUAN Lian ZHANG Ruohong LUO Chan XIAO Jianfang YE Zhaoqi GAO Boxu LIU Peng TANG Yi | 2019 | Chemical Research in Chinese Universities2019，35，4： | 2 |
| 8 | A newly developed ocean significant wave height retrieval method from Envisat ASAR wave mode imagery显示文摘The main objective of this paper is to propose a newly developed ocean Significant Wave Height (SWH) retrieval method from Envisat Advanced Synthetic Aperture Radar (ASAR) imagery. A series of wave mode imagery from January, April and May of 2011 are collocated with ERA-Interim reanalysis SWH data. Based on the matched datasets, a simplified empirical relationship between 22 types of SAR imagery parameters and SWH products is developed with the Genetic Algorithms Partial Least-Squares (GA-PLS) model. Two major features of the backscattering coefficient σ0 and the frequency parameter S10 are chosen as the optimal training feature subset of SWH retrieval by using cross validation. In addition, we also present a comparison of the retrieval results of the simplified empirical relationship with the collocated ERA-Interim data. The results show that the assessment index of the correlation coefficient, the bias, the root-mean-square error of cross validation (RMSECV) and the scattering index (SI) are 0.78, 0.07 m, 0.76 m and 0.5, respectively. In addition, the comparison of the retrieved SWH data between our simplifying model and the Jason-2 radar altimeter data is proposed in our study. Moreover, we also make a comparison of the retrieval of SWH data between our developed model and the well- known CWAVE_ENV model. The results show that satisfying retrieval results are acquired in the low-moderate sea state, but major bias appears in the high sea state, especially for SWH>5 m. | Chenqing Fan Xiaochen Wang Xudong Zhang Dong Gao | 2019 | Acta Oceanologica Sinica2019，38，9： | 2 |
| 9 | Validation of the “HY-2” altimeter wet tropospheric path delay correction based on radiosonde data显示文摘Wet tropospheric path delay(PD) is a highly variable term for the altimeter measurement of a sea surface height, caused by the refraction effect of atmospheric water vapor and cloud liquid water. In order to estimate PD values, the 'HY-2' system includes a calibration microwave radiometer(CMR) operating at 18.7, 23.8 and 37 GHz. The PD data of the CMR were compared and validated by coincident radiosonde profiles from ten globally distributed radiosonde stations during October 2011 to August 2012. The temporal interval was 1 h. In order to avoid land contamination, different spatial intervals between these two data sets were tested. The empirical fit function of PD uncertainty and spatial interval was found and extrapolated to the ideal situation that the data of CMR and radiosonde were totally coincident. The stability of the brightness temperature of the CMR and its impact on the PD correction was also studied. Consequently, the uncertainty of the PD algorithm of the CMR was estimated to be 2.1 cm. | WANG Jin ZHANG Jie FAN Chenqing WANG Jing | 2014 | Acta Oceanologica Sinica2014，33，5： | 2 |
