2Nutrients concentration and changes in decade-scale in the central Bohai Sea显示文摘The nutrients contents and distributions are discussed briefly, based on the data obtained in 1998~1999. Besides explanation of the results,a 20 a time series data of nutrients and biological parameters for central Bohai Sea are reviewed. It is found that both concentration and relative content of nutrients have been changed dramatically. The increase of nitrogen and decrease of phosphate and silicate led to the dramatically increase of N/P ratio and the decrease of Si/N ratio. The situation of nitrogen limiting in central Bohai Sea is gradually changing to that of relative lack of phosphate and silicate. The decrease of the Huanghe River input to the Bohai Sea may be responsible for this change. These in turn may limit the growth of diatom and thus promote the development of pyrrophyta if other conditions (e.g. temperature and hydrodynamics) are suitable. We conclude that this may be the major inducement factor of pyrrophyta red tide in the Bohai Sea.Yu Zhigang 1,Mi Tiezhu 1,Yao Qingzhen 1,Xie Baodong 1,Zhang Jing 11 .CollegeofChemistryandChemicalEngineering ,OceanUniversityofQingdao ,Qingdao 2 6 6 0 0 3 ,China 2001Acta Oceanologica Sinica2001,20,1:18
3足癣患者治疗现状调查显示文摘目的了解中国足癣患者的治疗现状,加强临床医生对相关诊治指南推荐方案的认知和理解。方法中国医师协会皮肤科医师分会组织全国9家医院进行中国足癣患者治疗现状问卷调查。结果共收集到问卷690份,结果显示我国足癣患者大多数选择自行购买外用抗真菌药物治疗,最常选用的外用药物为咪唑类药物,往往以瘙痒和/或皮疹消失作为停止治疗的依据,治疗最长时间中位数为2周,在治疗足癣的疗程上显示出明显不足。足癣患者常合并甲真菌病等其他皮肤癣菌病,同时其家庭成员患病率也较高,在治疗足癣患者的同时,应积极治疗其合并的其他皮肤癣菌病,也应同时对患者家庭成员进行治疗。结论本研究对更加有针对性地制定合理足癣预防和治疗方案并加强患者宣教具有重要作用。王爱平 高露娟 席丽艳 李铁男 段逸群 易顺强 刘卫兵 王秀丽 王桂芝 许爱娥 温海 0李若瑜 2014中国真菌学杂志2014,9,6:17
4Study on detection of coastal water environment of China by ocean color remote sensing显示文摘Coastal water environment is essentially enhanced by ocean color which is basically decided by substances concentration in water such as chlorophyll, suspended material and yellow substance. It is very difficult, even not possible, to detect water color by expensive ship routing, because of its temporal and spatial variety of feature and scales in the very complicated dynamical system of coastal water. With the development of satellite technique in the last 20 a, space sensors can be applied to detect ocean color by measuring the spectra of water leaving radiance.It is proven that ocean color remote sensing is a powerful tool for understanding the process of oceanic biology and physics. Since the 1980s, great attention has been paid to the advanced remote sensing technique in China, especially to development of satellite programs for the coastal water environment. On 7 September 1988, China launched her first polar orbit satellite FY-1A for meteorological and oceanographic application (water color and temperature) and the second satellite FY-1B two years later. In May 1999, China launched her second generation environment satellite FY-1C with higher sensitivies, more channels and stable operation. The special ocean color satellite HY-1 is planned to be in the orbit in 2001, whose main purpose is to detect the coastal water environment of China seas. China is also developing a very advantageous sensor termed as Chinese moderate imaging spectra radiometer (CMODIS) with 91 channels, which will be a good candidate of the third generation satellite FY-3 in 2003. The technical system of ocean color remote sensing was developed by the Second Institute of Oceanography (SIO), State Oceanic Administration (SOA) in 1997. The system included data receiving, processing, distribution, calibration, validation and application units. The Hangzhou Station of SIO, SOA has the capability to receive FY-1 and AVHRR data since 1989. It was also a SeaWiFS scientific research station authorized by NASA,USA to free receive SeaWiFS data from 16 September 1997. In the recent years, the local algorithms of atmospheric correction and inversion of ocean color have been developed for FY-1C and SeaWiFS, to improve the accuracy of the measurement from satellites efficiently. The satellite data are being applied to monitor coastal water environment, such as the spatial distribution of chlorophyll, suspended material and yellow substance, red tide detection and coastal current study. The results show that the ocean color remote sensing has latent capacity in the detection of coastal water environment.In consideration of the update technique progress of ocean color remote sensing and its more important role in the detection of coastal water in the 2000s, some suggestions are set forth, which would be beneficial to the design of a cheaper but practical coastal water detection system for marine environment preservation.Pan Delu 1,2 , Mao Tianming 1, Li Shujing 1,Huang Haiqing 11 .LaboratoryofOceanDynamicProcessesandSatelliteOceanographyofStateOceanicAdministration ,Hangzhou310 0 12 ,China 2 .LaboratoryofSubmarineGeosciencesofStateOceanicAdministration ,Hangzhou 3 2001Acta Oceanologica Sinica2001,20,1:16
5A New Approach to Nonlinear Partial Differential Equations显示文摘In this paper,a novel method called variational iteration method is proposed to solve nonlinear partial differential equations without linearization or small perturbations.In this method,a correction functional is constructed by a general Lagrange multiplier,which can be identified via variational theory.An analytical solution can be obtained from its trial- function with possible unknown constants,which can be identified by imposing the boundary conditions,by successively iteration.Jihuan HE (Shanghai University,Shanghai Institute of Applied Mathematics and Mechanics,Shanghai 2 0 0 0 72 ,China) 1997Communications in Nonlinear Science and Numerical Simulation1997,2,4:16

12Geochemistry of trace elements and Sr-Nd isotopes of foraminifera shell from the Okinawa Trough显示文摘Trace elemental associations and Sr-Nd isotopic compositions are of important to recognition of biogenic material from mixed marine sediments. The foraminifera shell from the Okinawa Trough strongly enriches Sr,P,Mn and Ba, enriches Li,U,Th,Sc,Co,Cu,Pb,Zn,Cr,Rb,Y,Sb and light rare earth elements,slightly enriches V,Ga,Zr,Nb,Cd and middle rare earth elements,is short of Mo,In,Sn,Cs,Hf,Ta,W,Ti,Bi and heavy rare earth elements. The mechanism of elemental enrichment in forminifera is the concentrations of trace elements in sea water and selective absorption of trace elements during foraminifera living, as well as the geochemical affinity between major elements and trace elements.The REE (rare earth elements)partition pattern of foraminifera shell of the Okinawa Trough shows enrichment of middle rare earth elements with slightly negative Ce anomaly,which are different from those of foraminifera of the Pacific Ocean.The Sr,Nd isotopic ratios of the Okinawa Trough foraminifera are 0 709 769 and 0 512 162,respectively, which are different not only from those of oceanic water, but also from those of river water of China’s Mainland, the former is slightly higher than those of oceanic water,but much lower than those of river water;the latter is slightly lower than those of oceanic water,but higher than those of river water,demonstrating that the Okinawa Trough sea water has been influenced by river water of China’s Mainland.Meng Xianwei 1,2 ,Du Dewen 1,2 ,Cheng Zhenbo 11 .FirstInstituteofOceanography ,StateOceanicAdministration ,Qingdao 2 6 6 0 6 1,China2 .KeyLaboratoryofMarineScienceandNumericalModeling ,StateOceanicAdministration ,Qingdao 2 6 6 0 6 1,China 2001Acta Oceanologica Sinica2001,20,1:4

16Three dimensional diagnostic,semidiagnostic and prognostic calculations of current in the East China Sea in April of 1994显示文摘Three dimensional diagnostic,semidiagnostic and prognostic models in the σ coordinate are used to compute the current in the East China Sea with wind and hydrographic data obtained from the investigation of ocean fluxes in the East China Sea during the cruise of April 1994.The computed results show that:the density and velocity fields and so on have been adjusted when time t ≈ 23 d, i.e.,the solution of semidiagnostic calculation has been obtained.The quasi steady state solution also has been reached after about 60 d.Comparing the results of diagnostic calculation with those of semidiagnostic and prognostic calculations,it is found that they agree qualitatively.For example,they all show that:(1)The Kuroshio flows along the shelf break of 200~1 000 m isobaths;(2)In the southeastern part of the computational region there is a stronger counter current with an anticyclonic eddy;(3)The volume transport through Section PN is about 30×10 6m 3/s and so on.However there are some quantitative differences between them.For example,(1)For the semidiagnostic results the Kuroshio current is stronger and clearer than that for diagnostic results and the Kuroshio width is more narrow than that for diagnostic results.This shows that the semidiagnostic calculation can better reflect the topography effect;(2)In most computed region the vertical component of velocity intensifies for semidiagnostic result,especially on the shelf break.Comparing the results of semidiagnostic calculation with those of prognostic calculation,they agree qualitatively,and also agree quantitatively in the middle of computed region.Wang Huiqun 1,2 ,Yuan Yaochu 1,21 .KeyLaboratoryofOceanDynamicProcessesandSatelliteOceanography ,StateOceanicAdministration ,China 2 .SecondInstituteofOceanography ,StateOceanicAdministration ,POBox .12 0 7,Hangzhou 310 0 12 ,China 2001Acta Oceanologica Sinica2001,20,1:3
