| 1 | Coral reef ecosystems in the South China Sea as a source of atmospheric CO_2 in summer显示文摘由空至海的 CO2 的领域大小在华南海的三个珊瑚礁石区域交换(即 Nansha 岛的 Yongshu 礁石环礁,南部的华南海(SCS ) ;Xisha 岛的 Yongxing 岛,北方中央的 SCS;并且在海南岛的 Sanya 的 Luhuitou Fringing 礁石,北 SCS ) 在 2008 和 2009 的夏天期间揭示了那 CO2 (pCO2 ) 的部分压力显示出的空气和表面海水常规日报周期。最小的价值在早上发生在晚上和最大的价值。在每三个学习区域的空气 pCO2 出现了小日报变化,当时大日报变化在海水 pCO2 被观察。日报海水 pCO2 的变化振幅是 70 摩尔摩尔? 1 在 Yongshu 礁石泻湖, 420619 摩尔摩尔? 1 在 Yongxing 岛礁石公寓,和 264579 摩尔摩尔上? 1 在 Luhuitou Fringing 礁石的礁石公寓上,并且 324492 摩尔摩尔? 1 在就在这 fringing 礁石外面的一个邻近的区域。关于空间关系,在越过华南海的由空至海的 CO2 流动有大差别(例如 0.4 mmol CO2 m ? 2 d ? 1 在 Yongshu 礁石, 4.7 mmol CO2 m ? 2 d ? 1 在 Yongxing 岛,并且 9.8 mmol CO2 m ? 2 d ? 1 在 Luhuitou Fringing 礁石)。然而,这些积极的值建议 SCS 的珊瑚礁石生态系统可以是到空气的 CO2 的网络来源。另外的分析显示了那日报在浅水礁石公寓的表面海水 pCO2 的变化主要被生物新陈代谢的过程控制,当那些被两个生物新陈代谢和水动力学因素更深的水泻湖和外部礁石区域调整时。不同于开的海洋,无机的新陈代谢在在珊瑚礁石生态系统影响海水 pCO2 变化起一个重要作用。 | YAN HongQiang YU KeFu SHI Qi TAN YeHui ZHANG HuiLing ZHAO MeiXia LI Shu CHEN TianRan HUANG LingYing WANG PinXian | 2011 | Chinese Science Bulletin2011，56，7： | 6 |

| 3 | Type-2 Fuzzy Control for Driving State and Behavioral Decisions of Unmanned Vehicle显示文摘In this paper, interval type-2 fuzzy sets, fuzzy comprehensive evaluation and the fuzzy control rules are synthesized to realize the control of unmanned vehicle in driving state and behavioral decisions. Compared to the type-1 fuzzy set, type-2 fuzzy sets have more advantages in handling the model based on uncertainties, linguistic information because the membership functions are fuzzy sets. Different membership functions are established for each factor when the unmanned vehicle is driving at different speed intervals. In addition, a new evaluation method is developed to analyze unmanned vehicle’s driving state. Finally, a set of dynamic fuzzy rules are sorted out, which can be applied to the unmanned vehicle’s behavioral decision-making and provide a new idea to related research. | Xuanming Zhao Hong Mo Kefu Yan Lingxi Li | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，1： | 5 |
| 4 | Testing coral paleothermometers(B/Ca, Mg/Ca, Sr/Ca, U/Ca and δ^(18)O) under impacts of large riverine runoff显示文摘Sea surface temperature(SST) proxies including B/Ca, Mg/Ca, Sr/Ca, U/Ca and δ18O were analyzed in the skeleton of a Porites coral collected from the Zhujiang River(Pearl River) Estuary(ZRE). These geochemical proxies are influenced by river runoff and this area of the northern South China Sea is strongly affected by seasonal freshwater floods. We assessed the robustness of each SST proxy through comparison with the local instrumental SST. Coral Sr/Ca shows the highest correlation with SST variations(r2=0.59), suggesting Sr/Ca is the most robust SST proxy. In contrast, coral δ18O(r2=0.46), B/Ca(r2=0.43) and U/Ca(r2=0.41) ratios were only moderately correlated with SST variations, suggesting that they are disturbed by some other factors in addition to SST. The poor correlation(r2=0.27) between SST and Mg/Ca indicates that Mg/Ca in coral skeletons is not a simple function of SST variations. This may ultimately limit the use of Mg/Ca as a coral paleothermometer. | CHEN Tianran YU Kefu ZHAO Jianxin YAN Hongqiang SONG Yinxian FENG Yuexing CHEN Tegu | 2015 | Acta Oceanologica Sinica2015，34，8： | 4 |
| 5 | Tropical Indian Ocean Basin Mode recorded in coral oxygen isotope data from the Seychelles over the past 148 years显示文摘The tropical Indian Ocean(TIO) displays a uniform basin-wide warming or cooling in sea surface temperature(SST) during the decay year of El Niδo-Southern Oscillation(ENSO) events. This warming or cooling is called the tropical Indian Ocean Basin Mode(IOBM). Recent studies showed that the IOBM dominates the interannual variability of the TIO SST and has impacts on the tropical climate from the TIO to the western Pacific. Analyses on a 148-year-long monthly coral δ 18 O record from the Seychelles Islands demonstrate that the Seychelles coral δ 18 O not only is associated with the local SST but also indicates the interannul variability of the basin-wide SST in the TIO. Moreover, the Seychelles coral δ 18 O shows a dominant period of 3–7 years that well represents the variability of the IOBM, which in return is modulated by the inter-decadal climate variability. The correlation between the Seychelles coral δ 18 O and the SST reveals that the coral δ 18 O lags the SST in the eastern equatorial Pacific by five months and reaches its peak in the spring following the mature phase of ENSO. The spatial pattern of the first EOF mode indicates that the Seychelles Islands are located at the crucial place of the IOBM. Thus, the Seychelles coral δ 18 O could be used as a proxy of the IOBM to investigate the ENSO teleconnection on the TIO in terms of long-time climate variability. | DU Yan XIAO JinJun YU KeFu | 2014 | Science China Earth Sciences2014，57，11： | 2 |
