After treatment by 0.2, 0.4 g/ml extracted liquid , the seed germination of tomato and pepper were decreased by 10.2％, 9.4％ and 46.7％, 34.7％ than that of CK resp. The extracted liquid at 0.2 g/ml could inhibit the growth of vegetable root, but had some promotion on growth of vegetable stem. The extracted liquid at 0.4 g/ml had the strong inhibition on the growth of vegetable root, but its inhibition on growth of vegetable stem was greatly variable in different species.

结果］曼陀罗浸提液可降低4种蔬菜种子的发芽速率，降低番茄和辣椒种子的发芽率；0.2、0.4 g/ml曼陀罗浸提液处理后，番茄和辣椒种子的发芽率分别比对照降低了10.2％、9.4％和46.7％、34.7％。0.2 g/ml曼陀罗浸提液抑制蔬菜根的生长，而对茎的生长却表现出促进作用；0.4 g/ml曼陀罗浸提液对蔬菜根的生长有很强的抑制作用，对茎段生长的抑制作用因物种不同而有很大差异。

Methods: The marine bacteria were isolated with the infinite dilution and plate streak technique and screened for antimitosis active strains by Pyricularia Oryzae model. The active strain 32-11-2-2 was subjected to morphological, physiological and biochemical study, and was classified by the analysis of the 16S rDNA sequence. Results A total of 421 strains of marine bacteria were isolated from marine water and sediment samples; 54 of them had antimitotic activity.

Now, if we filter a 4:4:4 YCbCr signal by subsampling the chroma by a factor of 2 horizontally, we end up with 4:2:2 YCbCr.

现在，如果我们通过在水平方向上对色度信号进行因数为2的子采样，对一个4：4：4 YCbCr 信号进行滤波，于是将得到4：2：2 YCbCr 。

The effect of flow rates, initial concentrations, resin bed heights, its height/ diameter ratios and temperature on breakthrough curves of sulfuric acid/2-naphthalenesulphonic acid, 2-naphthalenesulphonic acid/sulfurous acid and sulfuric acid/ 2-naphthalenesulphonic acid/sulfurous acid systems was investigated. Excellent agreement was obtained between experimental data and the suggested breakthrough data model, with which the breakthrough curves can be accurately predicted for multi-component adsorptive separation in resin bed, the experiment of adsorptive separation may be scaled up, and the plant may be designed.

This review will focus on the role of GluRδ2, one of the main players in this field. Special emphasis will be placed on the processes that regulate the rapid translocation from climbing fibres to parallel fibres of GluRδ2 and the role of GluRδ2 in the reduction of supernumerary climbing fibre contacts on a single Purkinje cell.

这篇综述将集中讲这一领域中的一个主要因素GluRδ2的功能，并特别强调了GluRδ2 的上行纤维到平行纤维的快速易位的调节过程和GluRδ2 在减少过多的上行纤维与单个蒲肯野细胞接触的过程中的作用。

Cerebral hemorrhage rat models were established via injection of autologous arterial blood in caudate nucleus. Two days after modeling, 5 μL BrdU-labeled human embryonic NSCs suspension was transplanted at four points surrounding hematoma cavity in the rats. After 1 and 2 weeks, rats were sacrificed. Adjacent sections were doubly stained by BrdU/microtubule-associated protein 2 (MAP-2) and BrdU/glial fibrillary acidic protein.

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.
