电激励O2（1△g）发生器的理论模拟研究

 建立了基于分子反应动力学的氧等离子体化学反应模型，该模型包括了电子与氧分子，以及氧原子与氧分子的碰撞反应过程。利用反应动力学理论计算并讨论了电激励O₂(¹△)发生器的放电参数，发现电子能量应小于2.5eV。电子浓度对O₂(¹△)产率的影响不大，当放电压力与气体线流速一定时，存在最佳的电子平均能量。     

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.     

Synthesis of 5,6-Dihydro-OSW-1 and Its Antitumor Activities

5,6-Dihydro-OSW-1 (1) was synthesized following our previous procedure for the total synthesis of OSW-1. This compound demonstrated slightly stronger potency than that of OSW-1 against the growth of cancer cells.

Solid Phase Synthesis of 2-Substituted 1,3-Oxazin-6-ones Using Resin-bound Cyclic Malonic Acid Ester

A facile solid phase synthesis of 2-substituted 1,3-oxazin-6-ones using polymer-supported Meldrum‘s acid has been reported. Reaction of the resin-bound cyclic malonic acid ester with triethyl orthoformate and subsequent double substitution with amide, afforded the corresponding polymer-supported acylaminomethylene cyclic malonic acid ester, which upon thermal treatment led to 1, 3-oxazin-6-ones in good yields and with high purity.

HL-1M边缘等离子体静电湍流扰动

对HL－1M边缘等离子体静电湍流扰动进行了初步的实验研究。获得了扰动的基本特征量，估计了低杂波引起的径向粒子流的变化。在加低杂波（2．45GHz)前、后，电子密度扰动和极向电场扰动的幅度及其关联性变化不大。虽然低杂波部分抑制了静电湍流，但在数量上不能解释粒子约束改善的实验结果。
