Dimensional Properties of Fractional Brownian Motion

Let B^α = {B^α（t）,t E R^N} be an （N,d）-fractional Brownian motion with Hurst index α∈ （0, 1）. By applying the strong local nondeterminism of B^α, we prove certain forms of uniform Hausdorff dimension results for the images of B^α when N 〉 αd. Our results extend those of Kaufman for one-dimensional Brownian motion.     

纳米级氧化铁的合成及其对六价铬的吸附性能研究

采用溶胶-凝胶法合成了纳米氧化铁,研究了合成条件,并采用TEM对产品进行了表征,测得产品的平均粒径为20-30nm.研究了纳米级氧化铁对Cr（Ⅵ）的吸附.在pH=3.0,吸附比为3.5×10-6:1×10-2（g/g）时,平均吸附效率为95.98％,最大吸附量为398.3μg Cr（Ⅵ）/g.采用2mol/LNaOH可完全洗脱纳米氧化铁所吸附的Cr（Ⅵ）,测定了回收后的纳米氧化铁对Cr（Ⅵ）的吸附效率,结果表明纳米级氧化铁可循环使用,这将为环境污水中Cr（Ⅵ）的治理及研究纳米材料的吸附行为提供参考.

Isolation and Structure Elucidation of Nortriterpenoids from Schisandra rubriflora

Seven new highly oxygenated nortriterpenoids, rubriflorins D–J ( 1 – 7 ), were isolated from the leaves and stems of Schisandra rubriflora, and their structures were elucidated on the basis of extensive analysis of spectroscopic data. These new compounds feature the opening of ring A compared with related known nortriterpenoids isolated from the genus Schisandra and showed weak activity against HIV‐1.     

HPLC法测定阿奇霉素葡萄糖注射液中阿奇霉素的含量

Ethylene–propylene copolymerization with bis(β‐enaminoketonato) titanium complexes activated with modified methylaluminoxane

Ethylene–propylene copolymerization, using [(Ph)NC(R₂)CHC(R₁)O]₂TiCl₂ (R₁ = CF₃, Ph, or t‐Bu; R₂ = CH₃ or CF₃) titanium complexes activated with modified methylaluminoxane as a cocatalyst, was investigated. High‐molecular‐weight ethylene–propylene copolymers with relatively narrow molecular weight distributions and a broad range of chemical compositions were obtained. Substituents R₁ and R₂ influenced the copolymerization behavior, including the copolymerization activity, methylene sequence distribution, molecular weight, and polydispersity. With small steric hindrance at R₁ and R₂, one complex (R₁ = CF₃; R₂ = CH₃) displayed high catalytic activity and produced copolymers with high propylene incorporation but low molecular weight. The microstructures of the copolymers were analyzed with ¹³C NMR to determine the methylene sequence distribution and number‐average sequence lengths of uninterrupted methylene carbons. © 2006 Wiley Periodicals, Inc.
