The experimental results show that under the present experimenal condition and in the cases without and with applied field, collisions are the reason leading to plane wave attenuation in the plasma. Plasma resonance absorption and upper hybrid resonant absorption mechanisms can not be found.

实验结果表明在非磁和本实验条件下，平面电磁波在等离子体中的衰减机理为碰撞吸收；在有磁和本实验条件下，平面电磁波在磁等离子体中的衰减机理同样为碰撞吸收，但是外加磁场的存在有限地改善了等离子体的吸波效应。

Based on the results, a substrate-induced fusion of the vesicles is proposed and get support from a fluorescence resonance energy transfer assay.

对此我们提出了底物诱导的囊泡相互融合的机理，并用荧光共振能量转移的方法证明了此机理。

Using a long-term reared housefly population which is very susceptible to pyrethroid insecticides as the susceptible strain, a population collected in 1993 in Shanghai and has been treaded by cyhalothrin as the resistant strain, we bioassayed their susceptibility to organophosphorus, carbamate, pyrethroid and organehloride insecticides. We also investigated the role of metabolic enzymes, i. e. esterase, GST, MFO and of target enzymes, i. e. AChE and 〓-ATPase in resistance to insecticides. Cyhalothrin resistance inheritance, the co-toxicity coefficient of cyhalothrin and methylene dithiocyanate was also studied. The insecticides resistance in adults and larvae of houseflies was compared and the mechanism of resistance differences between adults and larvae was discussed.

本文以采自野外并经过室内多代筛选的三氟氯氰菊酯抗性家蝇品系和室内多年饲养的敏感家蝇品系为试虫，测定了抗性家蝇品系和敏感家蝇品系对拟除虫菊酯杀虫剂三氟氯氰菊酯、氯菊酯、有机磷杀虫剂DDVP、氨基甲酸酯杀虫剂残杀威、有机氧杀虫剂DDT的抗性水平，并通过活体增效剂实验和离体生化实验研究了抗性品系的解毒酶和靶标酶的变化，本文还研究了三氟氯氰菊酯和增效剂I对抗性家蝇的增效作用及增效机理、家蝇幼虫和成虫对杀虫剂的抗性差异及其抗性差异的机理。

It is suggested that future research on agroforestry systems focus on comparisons among different components in different climatic conditions, competition processes and physiological mechanisms, plant allelopathy and the role and mechanism of mycorrhizae in plant competition, interactions between above- and below-ground competition and the effect of global climate change on plant competition of the agroforestry systems.
