To resolve the problem that the concentration of CO2 was hard to control in fields,KHCO3 was sprayed on soybean leaves and NaHSO3 was used to restrain photorespiration at the same time,so as to find the best application amount of KHCO3 and NaHSO3 to increase photosynthetic rate of soybean seedlings.

针对目前还难以控制田间CO2浓度的问题，采用在大豆幼苗叶片上喷施碳酸氢钾(KHCO3)的方法，同时用亚硫酸氢钠( NaHSO3)适当的抑制大豆的光呼吸，来提高CO2浓度进而提高光合速率。

But many types of treatment are available, including products applied to the skin, phototherapy, and oral medicines, which can help control psoriasis.

但是，许多类型的治疗可用，包括适用于皮肤，光疗产品，口服药物，它可以帮助控制牛皮癣。

Also, the surface properties of the materials before and after POMs is loaded on titania pillared clay will be investigated in some dedail in the study.

实验研究发现杂多酸在钛柱粘土负载后的光催化氧化性能并没有提高，其中原因可能是沉积的难以控制，有可能导致催化剂表面的覆盖和孔道的堵塞。

In order to suppress the heat effect of blue laser using plano concave cavity when working ,use Thermal Energy Converter to cont rol the temperature of gain medium Nd : YAG crystal and SHG LBO crystal.

为了解决平凹腔蓝光固体激光器晶体在工作中因热效应问题产生的影响，针对激光的增益介质Nd：YAG晶体和用以倍频的LBO晶体，采用半导体制冷器准确控制其工作时的温度。

By controlling the size of pump beam and inserting an intracavity aperture in the plano-concave cavity, we obtain good contrast optical bottles at semi-confocal, 1/3-, and 1/5-degenerate cavity configurations, respectively.

只要适当的控制泵浦光斑与腔内实光栏的大小，在半共焦腔、1/3简并腔、与1/5简并腔下可以产生不同但是对比度极佳的瓶型光束。

A lot of art works seem to be brighter and pretty, these all preannounce that a lot of artists in China are carrying on a sort of productive creation, which is controled by the capital and strategy, however it runs in opposite directions with the spirit of "Van Guard" in contemporary art.

很多艺术作品显得更光鲜亮丽和时尚。这些都预告着中国很多艺术家在进行一种生产性的创作，一种由资本控制的，具有策略性的创作，然而这却和当代艺术本身的"先锋"精神背道而驰。

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.
