3.America vegetable leafminer (Liriomyza sativae Blanchard ) was firstly found in Argentina in 1938. At present, the pest has been distributed in more than 40 nations and areas of 7 continents.
4.Shanghai Potential Paper Co., Ltd. ( C) was established in Shanghai by the US based Potential Group which ow 95% of the Sino-US joint venture (JV).
5.Over the Tibetan Plateau, strong vertical diffusion resulting from intense surface sensible heat flux to the overlying atmosphere contributes most to the boundary layer heating, condensation associated with large-scale ascent is another contributor to the lower layer heating.
6.Analyzing the basic pathological changes of acute hemorrhagic stroke(AHS),the assay looks back to recent ten-year research about the therapeutic methods of planing-liver and descending-yang,calming-wind and clearing-heat on AHS in the clinical and experimental.
7.In order to find out the rule of turbulence and to quantificationally analyze the vertical transport of energy and material over forest, the sensible heat flux and latent heat flux over broadleafed Korean Pine forest on Changbai Mountain are calculated, using the data measured by the Routine Meteorological Measurement System and Open-Path Eddy Covariance Measurement System, based on the eddy covariance and aerodynamic methods.
8.The simplified equivalent model of Sanxia nearby power network is established in PSS/E and MATLAB respectively.The influence and reasons of series compensation capacitor on system short circuit current are analyzed and studied.The coupling current and transient resuming voltage are analyzed,and some measures and advice are proposed.
9.The results show that pressure gradient force is stronger in the fifth pentad of May in 1998 than that in the first pentad of May in 1994. That ageosgtrophic wind is stronger in 1994 than that in 1995 is mainly resulted from the weaker stability in 1994. On the first pentad of May 1994, the main positive contributions to the simulated maximum southerly wind in the lower troposphere over the South China Sea are: latent heating processes, zonal temperature advection, vertical temperature convection and boundary effect.
