结果表明，当铅膏中的硫酸量降低后，蓄电池的充电接受性能和深循环寿命大大提高；木素磺酸盐与腐殖酸复合的有机膨胀剂较其单独使用，提高了负极在2小时率容量放电条件下的活性物质的利用率。

Sulfur can promote the formation of chlorophyll; sulfur involved in the process of nitrogen fixation, to increase the utilization rate of fertilizer; in cruciferous rape, peanuts propylene mustard oil, Liliaceae onions and garlic contained in Suanyou fat, such as sulfur compounds in human nutrition and medicine There are special effects to enhance the quality of these crops.

硫能促进叶绿素的形成；硫参与固氮过程，提高肥料利用率；十字花科中油菜、花生的丙烯芥子油，百合科葱、蒜中所含的蒜油等硫脂化合物在人体营养和医药方面有特殊的功效，提高这类作物的品质。

Photosynthetic rate and water utilization efficiency were increased, but malonic dialdehyde content and membrane permeability were decreased with polyamine treatment under hypoxia stress. At the same time, the fresh weight and dry weight was increased.

结果表明，外源多胺能显著提高低氧胁迫下黄瓜幼苗叶片的净光合速率和水分利用率，降低叶片中丙二醛含量和质膜透性，使幼苗鲜重和干重明显增加。

As open source software, DSpace is the most popular digital repository system in the world. And Manakin is a new web UI of DSpace which is based on XML.

DSpace是目前国内外知识库构建中利用率较高的开源软件系统，Manakin是DSpace系统基于XML用户界面的新版本。

Excessive calcium intake made the viscera coefficient of rats changed, and had certain harm to testicle and kidney and so on. The absorbability and using of calcium were decreased, which wasted calcium and increased metabolizable burden of body. At the same time, it made the concentration of serum zinc and serum iron depressed, but the serum calcium went up.

过量钙喂养使大鼠脏器、器官的脏体系数发生改变，对睾丸、肾脏等器官有一定危害；机体对钙的吸收、利用率下降，造成补钙剂的浪费，增加机体代谢负担，同时使血清铁、锌浓度降低，血清钙浓度增高，尿钙增加，是肾结石的潜在危险因素。

The equation expressing the relationship between the efffective heat utilization of laser and the parameters of laser coated layer was derived based on energy equilibrium and metallographical measurement .

利用金相检测法和能量平衡方程，推导和计算了激光熔覆过程中单位时间激光热有效利用率，并分析了影响因素。

This layer converts the energy of the red- and near-infrared spectrum, facilitating efficiency increases of up to 50 percent. The micromorph?

这一层会吸收光谱中的红光和近红外线的光能，这样大大提高了太阳光能的利用率，最终使得光电转换效率比单纯的非晶硅电池高出50％之多。

The utilization rate of N fertilizer of the former was significantly lower than that of the later, and the contribution of soil mineralizable N was relatively higher in the former, compared with the later.

前者对肥料氮的利用率较后者显著地低，且土壤矿化氮在所吸收的氮中的贡献率也相对较高。

Phosphorus presented in crops such as grains, beans, oil-bearing crops is in the form of phytate-phosphorus. The utilization rate of phosphorus in phytate by monogastric animals was very low because of the lack of phytase.

在动物饲料中富含磷的谷物、豆类和油料等作物中，磷的基本贮存形式是植酸磷，因单胃动物体内缺少能分解植酸的酶很难利用这些植酸中的磷，其利用率极低。

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。
