强流四脉冲电子束源实验研究

 为了进行强流多电子束源研究，对现有2MeV LIA 注入器进行了四脉冲改造，二极管脉冲电压约500kV。实验研究了天鹅绒阴极在四脉冲条件下的发射能力、传导电流负载效应以及阴极等离子体运动对阴极电子发射和束能量的影响。利用空间电荷限制流模型推算出阴极等离子体膨胀速率在1 ~4cm/μs之间。     

Synthesis of 2-Acyl-2H-1,2,3-diazaphospholes and Their Diels-Alder Reaction with Cyclopentadiene

2H-1,2,3-Diazaphospholes 3a-3h were prepared from various ketone acylhydrazones and phosphorus trichloride in the presence of triethylamine. Compounds 3 underwent feasible hetero-Diels-Alder reactions with cyclopentadiene to afford the respective anellated [1,2,3]diazaphospholes 4a--4d as well as 4a‘--4d‘ in moderate yields. The endo rule in the reaction was observed under kinetic control conditions.     

Novel Chiral Ferrocenyl Aziridino Alcohol Catalysts Promoting Asymmetric Addition of Diethylzinc to Aldehydes

Optically active aziridino alcohols containing ferrocenyl groups were prepared from commercially available L-threonine in excellent yields and used as catalysts to promote the asymmetric addition of diethylzinc to aryaldehydes to afford 1-arylpropanol in up to 84% enantiomeric excesses with moderate to good yields.     

Microwave-promoted Palladium Catalyzed Suzuki Cross-coupling Reaction in WaterI

A simple, rapid and environmental friendly method for the synthesis of biaryl compounds under microwave irradiation is reported.

支气管灌洗液中铜锌含量及铜／锌比值的观察

用原子吸收光谱法检测了肺癌患者灌洗液中铜、锌含量及铜／锌比值。结果表明：中央型肺癌组与肺部良性疾病组比较均有极显著差异；与周围型比较，铜、铜／锌具有显著性差异；而周围型肺癌组与良性组比较，除铜／锌比值有显著性差异，Ｃｕ、Ｚｎ均无统计学意义差异。
