| 1 | A review of progress in coupled ocean-atmosphere model developments for ENSO studies in China显示文摘El Nino-Southern Oscillation(ENSO) is the strongest interannual signal that is producedby basinscale processes in the tropical Pacific,with significant effects on weather and climate worldwide.In the past,extensive and intensive international efforts have been devoted to coupled model developments for ENSO studies.A hierarchy of coupled ocean-atmo sphere models has been formulated;in terms of their complexity,they can be categorized into intermediate coupled models(ICMs),hybrid coupled models(HCMs),and fully coupled general circulation models(CGCMs).ENSO modeling has made significant progress over the past decades,reaching a stage where coupled models can now be used to successfully predict ENSO events 6 months to one year in advance.Meanwhile,ENSO exhibits great diversity and complexity as observed in nature,which still cannot be adequately captured by current state-of-the-art coupled models,presenting a challenge to ENSO modeling.We primarily reviewed the long-term efforts in ENSO modeling continually and steadily made at different institutions in China;some selected representative examples are presented here to review the current status of ENSO model developments and applications,which have been actively pursued with noticeable progress being made recently.As ENSO simulations are very sensitive to model formulations and process representations etc.,dedicated efforts have been devoted to ENSO model developments and improvements.Now,different ocean-atmosphere coupled models have been available in China,which exhibit good model performances and have already had a variety of applications to climate modeling,including the Coupled Model Intercomparison Project Phase 6(CMIP6).Nevertheless,large biases and uncertainties still exist in ENSO simulations and predictions,and there are clear rooms for their improvements,which are still an active area of researches and applications.Here,model performances of ENSO simulations are assessed in terms of advantages and disadvantages with these differently formulated coupled models,pinpointing to the areas where they need to be further improved for ENSO studies.These analyses provide valuable guidance for future improvements in ENSO simulations and predictions. | ZHANG Rong-Hua YU Yongqiang SONG Zhenya REN Hong-Li TANG Youmin QIAO Fangli WU Tongwen GAO Chuan HU Junya TIAN Feng ZHU Yuchao CHEN Lin LIU Hailong LIN Pengfei WU Fanghua WANG Lin | 2020 | Journal of Oceanology and Limnology2020，38，4： | 4 |

| 5 | Ultrafast laser-chemical modification hybrid fabrication of hydrostatic bearings with a superhydrophobicity solid-liquid interface显示文摘Oil film vortex severely reduces the stability of hydrostatic bearings. A solid-liquid interface with drag and slip properties can weaken the oil film vortex of the bearing. Here, a combined picosecond laser ablation and chemical modification method is proposed to prepare surfaces with microbulge array structure on 6061 aluminum alloy substrates. Because of the low surface energy of the perfluorododecyltriethoxysilane modification and the bulge geometry of the microbulge array structure, the surface shows excellent superhydrophobicity. The optimum contact angle in air for water is 164°, and that for oil is 139°. Two surfaces with “lotus-leaf effect” and “rose-petal effect” were obtained by controlling the processing parameters. The drag reduction properties of superhydrophobic surfaces were systematically investigated with slip lengths of 22.26 and 36.25 μm for deionized water and VG5 lubricant, respectively. In addition, the superhydrophobic surface exhibits excellent mechanical durability and thermal stability. The proposed method provides a new idea for vortex suppression in hydrostatic bearings and improves the stability of bearings in high-speed operation. | GUO MingHui RONG YouMin HUANG Yu FENG XiaoLin HU HaiDong WU CongYi ZHANG GuoJun | 2024 | Science China(Technological Sciences)2024，67，3： | 0 |
| 6 | A new ensemble-based targeted observational method and its application in the TPOS 2020显示文摘Ensemble Kalman filter-based targeted observation is one of the best methods for determining the optimal observational array for oceanic buoy deployment.This study proposes a new algorithm suitable for a‘cross-region and cross-variable’approach by introducing a projection operator into the optimization process.A targeted observational analysis was conducted for El Niño–Southern Oscillation(ENSO)events in the tropical western Pacific for the Tropical Pacific Observation System(TPOS)2020.The prediction target was at the Niño 3.4 region and the first 10 optimal observational sites detected reduced initial uncertainties by 70%,with the best observational array located where the Rossby wave signal dominates.At the vertical level,the most significant contribution was derived from observations near the thermocline.This study provides insights into understanding ENSO-related variability and offers a practical approach to designing an optimal mooring array.It serves as a scientific guidance for designing a TPOS observation network. | Weixun Rao Youmin Tang Yanling Wu Zheqi Shen Xiangzhou Song Xiaojing Li Tao Lian Dake Chen Feng Zhou | 2023 | National Science Review2023，10，11： | 0 |
| 7 | Preliminary crystallographic studies on two insulin analogues which retain high biological activities after alterations in A chain显示文摘Using Fmoc solid phase synthesis and site-directed gene mutagenesis, two insulin analogues, [A13-14GABA,A21Ala] porcine insulin and [A3Thr] human insulin, have been prepared respectively, which retain high biological activities. The results show that non-coded y-amino butyric acid (GABA) could replace the dipeptide, Leu-Tyr, in A13-A14 of insulin and | Yiding Huang Hui Chen Youmin Feng Jiping Zhang | 1999 | Chinese Science Bulletin1999，44，16： | 0 |
| 8 | A simple,economical method of converting gene expression products of insulin into recombinant insulin and its application显示文摘A method, by which the gene expression product of recombinant single chain insulin can be converted into insulin by directly digesting with trypsin, has been established. This method has been used in process of porcine insulin precursor (PIP), [B16Ala]PIP and [B26Ala]PIP into (desB30)insulin, (desB30)[B16Ala]insulin and (desB30)[B26Ala]insulin, respectively, and all of them retain full biological activity of that of their corresponding parent, recombinant human insulin, [B16Ala]insulin and [B26Ala]insulin. The results further demonstrate that the C-terminal residue of B chain is not necessary for insulin's biological activity. Compared with the method of transpeptidation, this method is simple, with a high yield, and avoids the use of organic reagents, and in comparison with the trypsin/carboxypeptidase method, it omits the use of carboxylpeptidase. Besides, (desB30)[B16Ala]insulin and (desB30)[B26Ala]insulin still remained without self-association property as that of their parents, which demonstrate that they are monomeric insulin. So they can be used for substituting for monomeric insulin, [B16Ala]insulin and [B26Ala]insulin, in clinical applications. | ZHANG Zhou, CHEN Hui, TANG Yuehua and FENG Youmin(Institute of Biochemistry and Cell Biology, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, Shanghai 200031, China) | 2003 | Progress in Natural Science:Materials International2003，13，8： | 0 |
