| 1 | Ecological provinces of spring phytoplankton in the Yellow Sea:species composition显示文摘Phytoplanktonic ecological provinces of the Yellow Sea(31.20°–39.23°N, 121.00°–125.16°E) is derived in terms of species composition and hydrological factors(temperature and salinity). 173 samples were collected from 40 stations from April 28 to May 18, 2014, and a total of 185 phytoplanktonic algal species belonging to 81 genera of 7phyla were identified by Uterm?hl method. Phytoplankton abundance in surface waters is concentrated in the west coast of Korean Peninsula and Korea Bay, and communities in those areas are mainly composed of diatoms and cyanobacteria with dominant species of Cylindrotheca closterium, Synechocystis pevalekii, Chroomonas acuta,Paralia sulcata, Thalassiosira pacifica and Karenia mikimotoi, etc. The first ten dominant species of the investigation area are analyzed by multidimensional scaling(MDS) and cluster analysis, then the Yellow Sea is divided into five provinces from Province I(P-I) to Province V(P-V). P-I includes the coastal areas near southern Liaodong Peninsula, with phytoplankton abundance of 35 420×10~3–36 163×10~3 cells/L and an average of 35 791×10~3 cells/L, and 99.84% of biomass is contributed by cyanobacteria. P-II is from Shandong Peninsula to Subei coastal area. Phytoplankton abundance is in a range of 2×10~3–48×10~3 cells/L with an average of 24×10~3cells/L, and 63.69% of biomass is contributed by diatoms. P-III represents the Changjiang(Yangtze River) Diluted Water. Phytoplankton abundance is 10×10~3–37×10~3 cells/L with an average of 24×10~3 cells/L, and 73.14% of biomass is contributed by diatoms. P-IV represents the area affected by the Yellow Sea Warm Current.Phytoplankton abundance ranges from 6×10~3 to 82×10~3 cells/L with an average of 28×10~3 cells/L, and 64.17% of biomass is contributed by diatoms. P-V represents the cold water mass of northern Yellow Sea. Phytoplankton abundance is in a range of 41×10~3–8 912×10~3 cells/L with an average of 1 763×10~3 cells/L, and 89.96% of biomass is contributed by diatoms. Overall, structures of phytoplankton community in spring are quite heterogeneous in different provinces. Canonical correspondence analysis(CCA) result illustrates the relationship between dominant species and environmental factors, and demonstrates that the main environmental factors that affect phytoplankton distribution are nitrate, temperature and salinity. | ZHANG Shan LENG Xiaoyun FENG Yuanyuan DING Changlin YANG Yang WANG Jing WANG Houjie SUN Jun | 2016 | Acta Oceanologica Sinica2016，35，8： | 7 |

| 3 | VIBRATION MEASUREMENT OF DOUBLE-ENDED TUNING FORKS RESONATOR显示文摘提高调节叉(DETF ) 的双 ended 的连贯和可靠性共鸣器,共鸣器颤动的一个测量系统被介绍检查它的动态特征。激光 Doppler 技术被利用,在 DETF 颤动速度和光电探测器的产量电流之间的关系被获得。共鸣器颤动方程也被分析,它的开车力量仅仅取决于直接当前的偏爱电压和其他的电压的振幅。而且,基于测量驾驶控制电路的一个特殊共鸣器被设计。电路的振幅和频率被一台计算机控制以便 highlys 桌子和强壮的开车信号能是输出。驾驶并且测量 double-endedtuning 叉的实验被做了。驾驶信号的频率是 8 kHz,驾驶电压的 peak-to-peak 价值是 140 V。试验性的结果显示共鸣器能被驾驶控制电路稳定地驾驶, DETF 的动态特征可以在实时被测量。 | LENG Changlin ZHANG Guoxiong ZHONG Ying JIANG Chengzhi YU Fusheng | 2006 | Chinese Journal of Mechanical Engineering2006，19，1： | 0 |
