With the Sand culture method, influences of different magnesium levels (0%、50%、100%、150%、200% and 300%) was explored to the wheat seedlings of different stages. Many targets such as plant height, root length, biomass, content of chlorophyll, activity of root, RGY, RGR and ratio of root to crown of the wheat were mensurated at the time of 7d, 15d and 30d of two leaves stage of wheat seedlings after their endosperms were removed at different magnesium levels.The results showed that different magnesium levels had unlike influences over the wheat seedlings.

以小麦为试材，采用砂基培养的方法，在镁浓度分别为对照组的0%、50%、100%、150%、200%和300%的营养基质上，培养剔除胚乳后的二叶期小麦幼苗7d、15d及30d，并分别测定该3个时间段小麦幼苗的株高、根长、地上部和地下部的生物量、叶绿素含量、根系活力以及相对生长速度、相对生长速率和根冠比等指标，研究不同供镁水平对不同时期小麦幼苗生长速率的影响。

For the second part, the damping behavior of Mg matrix composite was studied. It is found that the graphite fiber achieves better damping capacity than other reinforcements. The phase transformation happened in the Mg matrix can improve damping capacity and with the increase of reinforcement damping capacity can also be improved at high temperature.

其次，对镁基复合材料的阻尼行为的研究，发现石墨纤维比其它增强物具有更好的阻尼效果，基体镁合金的相变过程能提高复合材料的阻尼性能，增加增强物含量能增加复合材料的阻尼且高温下的效果更好。

In this research, waste activated alumina and basic magnesium carbonate were used as raw materials to synthesize magnesium aluminate spinel by double step firing process.

本研究利用废活性氧化铝与碱式碳酸镁为主要原料，二步煅烧法制备镁铝尖晶石材料。

It is difficult to realize a large-scale production of Mg partsthrough press forming and stamping process, which greatly restricts their appl...

但镁合金的塑性随温度的升高而显著改善，这就使镁合金在高温下通过锻压成形和超塑成形来生产所需的零件成为可能。

Choose materials include the fuse block which content MgO within 5%~30%, magnesium material and other glaze material.

Application of Mg-desulfurization in plant flue gas treatment,advantage of Mg-desulfurization and desulfurizing efficiency are introduced.

介绍了镁法脱硫在电厂烟气处理中的工程应用，以及镁法脱硫的优点及脱硫效率。

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.
