目的分析对约氏疟原虫不易感的大劣按蚊和易感的斯氏按蚊基因组RAPD谱带并测序，探讨媒介按蚊基因型与疟原虫基因型间的相互关系。

The Antennal ultrastructures of the two closely related wasp species, Aprostocetus prolixus and Aprostocetus fukutai, were observed by scanning electron microscope. The types, numbers, morphological characteristics and distribution patterns of the antennal sensilla of the two species were described, and the differences between two sexes were compared too.

利用扫描电镜观察了同属的桑天牛卵啮小蜂和桑天牛长尾啮小蜂的触角感器，对这两种寄生蜂触角感器的种类、形态、数量及分布进行了描述，并对雌雄两性触角之间的差异做了比较。

In the present study, tungsten oxide nanomaterials were synthesized by a modified plasma arc gas condensation technique. The effects of the plasma currents (70~90 A), chamber pressures (200~600 torr), production time（3~12 min）, oxygen partial pressure Ar:O2（1~6:1）and plasma including the hydrogen（0~10 %）on the preparation of tungsten oxide nanostructures were investigated. Pre-treatment on the tungsten oxide nanorods for surface modification was investigated by atmospherical plasma jet. The optical, filed emission, and gas sensing characteristics of tungsten oxide nanopowders were also examined.

本研究系利用电浆电弧气凝合成法来制备氧化钨奈米材料，分别探讨不同腔体压力（200~600 torr）、电浆电流（70~90 A）、制备时间（3~12 min）、氧分压Ar：O2（1~6：1）、电浆气含氢量（0~10 %）对於产物的形貌、相态影响，并使用常压低温电浆设备对氧化钨奈米棒进行表面处理，且针对氧化钨奈米材料的光学、场发射以及使用自行组装气体感测量测设备量测其气体感测特性。

In this thesis, research on alleviation of autotoxicity by planting mixture of Chinese fir and Broadleaf trees and developing undergrowth vegetation were also done. The results showed that Michelia macclurei and Cinnamomum camphora had positive allelopathic effect on the growth of Chinese fir saplings and developing undergrowth vegetation improved soil decline of Chinese fir plantation.

另外，论文还从植物化感作用的角度，对克服杉木人工林连栽障碍的其它生产措施，如营造混交林及人促林下植被的发育生长，进行了研究：提出了与杉木化学生态关系良好的两种伴生树种，并从化感作用角度证明人促林下植被发育有利于克服杉木人工林的连栽障碍。

Forestry management methods on alleviation of autotoxicity in Chinese fir plantation were also studied. Root-stumps from last Chinese fir pure plantation have a negative effect on the replanted Chinese fir saplings because of phenolics from decomposing root-stumps.

本文还针对减轻杉木人工林化感自毒作用的林业经营措施进行了研究，发现杉木人工纯林中的采伐剩余物根桩对下茬杉木幼树的更新有不利的影响，这种不利的影响来自于根桩分解过程中释放的酚类化感物质。

NRR非常感兴趣来自神经解剖、病理、生理、生物化学、药理、免疫、发育等多学科、多层面的题材，感兴趣发表以基础实验性研究为主的揭示大脑皮质、海马、松果体、神经胶质细胞、脊髓神经元、周围神经元以及运动、感觉乃至植物神经损伤与再生的研究原著，对有助于认识神经再生正常和异常机制的临床类文章，如罕见病例报告、调查分析等也可纳入范围。

Tension headache tends to be chronic or continuous and commonly originates in the occipital or bifrontal region, then spreads over the entire head. It is usually described as a pressure sensation or a viselike constriction of the skull.

紧张型头痛往往表现为慢性或持续性，通常始于枕部或双额部，然后扩散到整个头部，常被病人描述为受压感或颅紧箍感。

It is characterized by that firstly, preparing silver bromiodide flake microcrstalline emulsion, then utilizing silver halide solution to corrode core of silver bromide to prepare the invented hollow silver bromiodide flake microcrystal whose form is triangle or hexagon and whose surface possesses small holes and pits, and the core of the microcrystal is silver bromide and its external layer is silve bromidiode, its iodine content is 1-10 mol%, and the light sensitivity of the emulsion is greatly raised.

首先制备溴碘化银薄片微晶乳剂，再利用卤化银溶剂使溴化银内核腐蚀，制备成的中空溴碘化银薄片微晶呈三角形或六边形，表面上有小孔和凹坑，微晶的内核为溴化银，外层为溴碘化银，其碘含量为1―10mol％；无论从色盲乳剂，还是经光谱增感乳剂的感光度都有大幅度的提高。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
