A local positive feedback of the tropical Pacific ocean-atmosphere system on interdecadal timescales

SINCE THE 1990S, THE CLIMATIC VARIABILITY ON INTERDE- CADAL TIME SCALES BECAME THE FOCUS OF THE INTERNATIONAL CLIMATOLOGY RESEARCH MISSIONS[1―3]. ON TIME SCALES OF A DECADE OR MORE, THE OCEAN CIRCULATION PREDOMINATEDHEAT BALANCE AND HYDROLOGICAL CYCLE, S…     

Surface modification of poly（vinyl chloride） by long-distance and direct argon RF plasma

AS AN ELECTRICALLY NEUTRAL, HIGHLY IONIZED GAS COM- POSED OF IONS, ELECTRONS, AND NEUTRAL PARTICLES, PLASMA IS A PHASE OF MATTER DISTINCT FROM SOLIDS, LIQUIDS, AND NOR- MAL GASES,KNOWN AS THE FOURTH STATE OF MATTER[1]. RECENT YEARS SEE GREAT PROGRESS IN P…     

Effects of stem structure and cell wall components on bending strength in wheat

Stem is an important organ consisting of storage, transportation and mechanical tissues and is closely related to yield. There is an irregular cavity in the ce- real crop stems and the lower the location, the shorter and thicker the walls of the internode…     

Using of the surface plasmon resonance cytosensor for real-time and non-invasive monitoring of cellular effects in living C6 cells induced by PMA

By cell and molecular biology, the traditional life science research has been improved into modern ex-perimental science. Because cell is the basic structural and functional unit of the mysterious life, the study of life phenomena will be ultimately embodied into the study of cell biology. How to acquire a dynamic knowledge of the intricate biomolecular reactivity and process in living cells has become one of the hotspots in recent biological researches. For the complexity of cellular effects,…     

Synthesis and photocurrent response of porphyrin-containing conjugated polymers

In recent years conjugated polymers have attracted considerable attention because of their potential appli- cations in the fields of light emitting diodes, photo- voltaic devices, and sensors[1―7]. In the fabrication of semiconductor photovoltaic devices…     

Sr-Nd isotope geochemistry of eolian dust of the arid-semiarid areas in China： Implications for loess provenance and monsoon evolution

Strontium (Sr) is a divalent alkaline earth element. Its ionic radius (0.113 nm) is slightly larger than that of calcium (0.099 nm), and Sr thus substitutes isomor- phously for Ca in many minerals. Neodymium (Nd) is a rare earth element. Its chemical prop…     

Crystal structure determining of 7-ADCA based on X-ray powder diffraction

Traditionally, crystal structure data can be collected and determined from single-crystal X-ray diffraction. However, in the fields of organic and macromolecular crystallography, it is often difficult or impractical to grow single crystals with suitable sizes and purity. Therefore, it will be benefited from the newly growing analytical tool that combining X-ray powder diffraction based on polycrystalline samples and ab initio calcula- tion[1]. 7-ADCA is one of the most important intermediate…

金等离子体辐射不透明度的计算

考虑到能级的精细结构，将谱线能级用类氢近似细分，改进了平均原子模型中束缚．束缚跃迁吸收系数的计算方法．用改进后的平均原子模型计算高Z元素Au等离子体在一定温度和密度下的辐射不透明度，计算结果表明该模型的计算结果比原平均原子模型更接近Monte-Carlo模型的计算结果，而且计算量比Monte-Carlo模型少得多．
