1Application of a catch-based method for stock assessment of three important fisheries in the East China Sea显示文摘Most fisheries in China do not have maximum sustainable yield(MSY) estimates due to limited and poor data.Therefore, finding a common method to estimate MSY or total allowable catch(TAC) for fishery management is necessary. MSYs of three important fisheries in the East China Sea were evaluated through a catch-based model.Estimates for intrinsic rate of increase(r) and five levels of process error were considered. Results showed hairtail Trichiurus japonicas(Temminck and Schlegel) and small yellow croaker Larimichthys polyactis(Bleeker) fisheries experienced overfishing from the mid-1990 s to the early 2000 s, and the suggested TACs were 55.8×10~4 t and9.06×10~4 t, respectively. Decades of overfishing in wintering and spawning grounds of large yellow croaker Larimichthys crocea(Richardson) caused the fishery's collapse in the 1980 s, and it has not recovered until today.The Catch–MSY model generated similar estimated MSYs with other methods and may be a useful choice for the assessment of regional stocks in China.ZHANG Kui ZHANG Jun XU Youwei SUN Mingshuai CHEN Zuozhi YUAN Meng 2018Acta Oceanologica Sinica2018,37,2:14
2A Novel Approach of Electromagnetic Compatibility Conducted Susceptibility Analysis Based on Gaussian Even Pulse Signal显示文摘The purpose of the electromagnetic compatibility conducted susceptibility test for interconnected cables in the system is to evaluate its ability to operate acceptably when subjected to interference.We propose a novel conducted susceptibility analysis approach:by injecting the Gaussian even pulse signal,we find that the susceptibility threshold of the system shows two different patterns with the change of signal parameters;then we locate the cause of the susceptibility of the device by analyzing the threshold level curves.The effectiveness of the proposed approach is verified by testing with devices containing digital modules such as navigation receivers.The proposed approach facilitates a deeper understanding of the susceptibility mechanism of systems and their appropriate electromagnetic compatibility design.Youwei MENG Yanhua PENG Haoyang ZHANG Lilin LI Donglin SU 2024Chinese Journal of Electronics2024,33,2:0
