O2 producing velocity and MDA content in Lemont\'s leaves and leafsheaths of Si+ rice plants were lower than those of Si- rice plants significantly afterinoculating, and SOD、POD、CAT activities of Si+ rice plants were higher than those ofSi- rice plants significantly.

说明硅在水稻叶鞘内侧、叶表和厚壁细胞积累，起到了物理屏障的作用，延缓了纹枯病菌的扩展。5、阐明了施硅增强水稻抗纹枯病的生理生化机制(1)接种纹枯病菌后，两个水稻品种91SP和Lemont的叶鞘和叶片超氧阴离子自由基O2性紊乱，CAT活性明显下降；抗病品种91SP叶鞘和叶片施硅处理的O2产生速率小于缺硅处理，叶鞘和叶片MDA含量在接种第3 d后显著低于缺硅处理，叶鞘SOD、POD、CAT活性在接种1 d后一直显著高于缺硅处理，叶片SOD、POD、CAT活性在接种3 d后显著高于缺硅处理；感病品种Lemont叶鞘和叶片施硅处理的O2产生速率、MDA含量始终显著小于缺硅处理，SOD、POD、CAT活性始终显著大于缺硅处理。

It was shown that the root elongation was inhibited and the malonaldehyde content in root apices and the antioxidase activities of root apices were increased under Al stress (30 μmol/L), while the effects of Al were significantly alleviated by the addition of Si (1.4 mmol/L). Moreover, both Si added before Al treatment and Si added simultaneously with Al treatment could alleviate these effects. On the other hand, the cultivar of Seca was shown to be more sensitive to Al than other cultivars in the absent of Si, while Al-resistance distinction among the cultivars of stylosanthes turned to be non-significant in the present of Si in the pre-cultured solution or both pre-cultured and Al-treatment solutions.

研究结果表明，在铝(30 μmol/L)胁迫条件下柱花草根伸长受阻、根尖丙二醛含量和抗氧化酶活性显著增加，而硅(1.4 mmol/L)处理增加根中硅的含量而降低了铝对根伸长、MDA含量和抗氧化酶活性的影响，且铝处理前12h供给的硅和前处理溶液及铝溶液中均加硅处理的影响均显著；在不加硅条件下西卡品种的耐铝性显著低于其它品种，而经硅预处理的植株和在预处理及铝处理期间均供应硅的植株的耐铝性不同品种间的差异不显著。

Based on the FT-IR analysis of molecular sieve film on the cordierite supports, a shoulder peak at 1050cm-1 should be the vibration of out framework Si-O, and not strong interrelated with the size and shape of TS-1 crystal.

通过对堇青石上的分子筛涂层进行FT-IR分析，发现1050 cm-1处的肩峰是由分子筛骨架外的Si-O键振动所引起的，而与分子筛的晶粒大小和晶体形状关系不大。

Plasma assisted molecular beam epitaxy was employed to prepare ZnO thin films on Si(111) substrate.

The SiC films were grown by solid-source molecular beam epitaxy at different deposition rates on Si (111) substrate.

采用固源分子束外延生长技术，用不同的蒸发速率，在Si(111)衬底上生长SiC薄膜。

The intensity of NP peak of type-Ⅱ initailly increased with the increase of the excitation power and decreased thereafter. This is due to the electrons and the holes were localized in different space of typ-Ⅱ QW, then the band bending occurs when the carrier concentration increases with the power, NP peak shft to high energy. The electron transited to relaxed Si〓Ge〓 layer and combined with the localized holes radiatively.

型量子阱的NP峰随激发功率增加先增加后减小，这是由于在Ⅱ型量子阱中电子和空穴不在空间同一位置，较强激发功率下产生的高浓度载流子引起能带弯曲严重，NP峰向高能方向移动，到某一定程度时开始出现电子跃迁至弛豫Si〓Ge〓层与其中的空穴复合发光。

VCTS-KH560-Si was characterized by means of FTIR,TGA and gravimetric analysis.

然后将香草醛接枝壳聚糖作为反应的原料，制备键合硅胶固定相(VCTS-KH560-Si)，并用傅立叶变换红外光谱、热分析和质量分析法等手段进行表征，证明键合产物性质稳定。

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.

交际能力和语法的关系应该是目标与途径的关系。
