Microwave Synthesis, Characterization and DNA-binding Properties of a New Cobalt（ Ⅱ ） Complex with 2,6-Bis（benzimidazol-2-yl）pyridine

A new cobalt(Ⅱ) complex with tridentate ligand 2, 6-bis (benzimidazol-2-yl)pyridine has been synthesized by microwave irradiation method and characterized by elemental analysis,electrochemical and spectral methods. The binding of the complex with calf thymus DNA has also been investigated by absorption and fluorescence spectra.     

Baker＇s Yeast Mediated Reduction of Optically Active Diketone

Baker‘s yeast mediated reduction of optically active diketone is described. The two keto groups are efficiently differentiated and the ee value of the recovered material is considerably raised. It affords highly optically active key intermediates efficiently for the synthesis of natural polyhydroxylated agarofuran products.     

Thermal Oxidation of Polyethylene Films Containing Dispersed Copper and Amine Antioxidant

Thermal oxidation of polyethylene filled with dispersed copper and containing an amine antioxidant was studied. The concentration ranges in which the catalytic effect of the metal on the polymer oxidation or the stabilizing effect of the antioxidant prevails were determined. Under certain conditions, dispersed copper enhances the stabilizing effect of the antioxidant.

海口市番茄反季节栽培品种比较试验初报

海口市番茄生产的正常季节是冬种春收。其产量虽然较高,但产值较低。本试验是通过引进耐热番茄品种,将播种期推迟到二月春种夏收,即反季节栽培。试种结果初步表明:泰引3号、扬帆2号等引进品种,在气温较高的条件下,植株生长正常,座果率较高,产量与品质能达到当地正常季节栽培的水平。我们初步认为,泰引3号比较理想,可在海口市郊进一步试种。     

理想非线性单组分色谱模型理论解与实验的比较

用气相色谱的分析方法研究了理想非线性单组分不同温度下的流出曲线，用＂特征点＂法回归出了各组分的物理常数Ｇ和ｂ，代入理论模型公式，并与实验结果进行子比较。     

生长调节剂对大叶白蜡幼苗生长的影响

对一年生大叶白蜡实生苗用3种不同浓度的赤霉素（GA3）、ABT生根粉7号（ABT7）、萘乙酸（NAA）进行处理。结果表明，3种生长调节剂对大叶白蜡幼苗生长有明显的促进作用。处理后的苗木提高，生长加快，茎干增粗，叶片增大，抗性增强，其中以50mg/L的GA3作用最为显著。     

Bio-Plasmonics: Nano/micro Structure of Surface Plasmon Resonance Devices for Biomedicine

We have reported a novel design of surface plasmon resonance (SPR) device, which uses alternating dielectric layers to enhance the SPR signal quality and modulate its resonant position. Admittance loci method of thin film design has been used in the design of such a device. The use of biomolecular thin film, such as DNAs or Porteins, in this design can result in resonant condition of wavelength changes as well. Bio-plasmonics is proposed for the research and development of novel devices, which use biomolecules as a part of the plasmon oscillation system to actively interact with nano/micro structure.     

长江堤防工程地质信息处理模型及技术方法

长江中下游的主要防洪工程是长江干堤 ,长江堤防线路长、工程浩大、堤基工程地质水文地质条件复杂 ,涉及大量的已有地质数据和资料。今后在整治加固堤防的工程地质勘察工作中 ,还需随时进行数据的收集、存储、检索、分析、统计和维护 ,随时调用这些数据进行综合处理、编制报告和图件 ;在防汛期间可以针对堤防险工险段的险情 ,随时查询和调用有关的资料、数据或者图件 ,提供采取抢险措施决策的地质依据。这既提高了地质数据的利用价值和利用率 ,又保证了信息的准确性、完整性和共享性。因此 ,建立合理的长江堤防工程地质信息处理模型及其成熟的技术方法具有重要的意义。
