With consideration of environment, people begin to confine usage of toxic chemicals such as chromate, nitrite.

随着各方面对环境影响的考虑，传统的中性介质缓蚀剂如铬酸盐、亚硝酸盐的应用逐渐受到限制，开发研究环保型的、高效的缓蚀剂是非常必要的。

With consideration of environment, people begin to confine usage of toxic chemicals such as chromate, nitrite. It is very necessary to develop efficient inhibitors that are not detrimental to environment.

随着各方面对环境影响的考虑，传统的中性介质缓蚀剂如铬酸盐、亚硝酸盐的应用逐渐受到限制，开发研究环保型的、高效的缓蚀剂是非常必要的。

The results are:(1) The brightness of the specimens will decrease and the chromatism will increase with the prolongation of time of heat treatment. Compared to heat treatment in vacuum, the specimens have more color changes after heat treatment in air, with the same temperature and time of heat treatment.

该研究的结论为：(1)在相同条件下，随着处理时间的延长，试材的明度减小，色差增大；空气介质中热处理和真空中热处理相比，在处理温度和时间相同的情况下，前一种方法处理后的试材材色较深。

In this study the change of brightness, chromatism and infra red spectra of compressed China fir during heat treatment in air or heat treatment in vacuum are studied.

该文重点研究了杉木压缩木材在经过空气介质中热处理和真空中热处理后明度、色差和红外光谱的变化。

The results are:(1) The brightness of the specimens will decrease and the chromatism will increase with the prolongation of time of heat treatment. Compared to heat treatment in vacuum, the specimens have less brightness and more chromatism after being heat treated in air, under the conditions of same temperature and time of heat treatment.

该研究的结论为：①在相同条件下，随着热处理时间延长，木材明度减小，色差增大；空气介质中热处理和真空中热处理相比，在处理温度和时间相同的情况下，前一种方法处理后的木材明度更小，色差更大。

The water-saturated and boiled specimens of China fir are hot pressed with the average compression rate of 50%. Then they are heat treated in a common oven or in a vacuum oven, with the temperatures of treatment of 140,160,180,200,220℃, respectively. Then the brightness, chromatism, infra red spectra of the specimens are measured and discussed.

为了探讨热处理过程中杉木压缩木材的材色变化规律，以及材色和木材化学主成分变化之间的关系，该研究测定了空气介质和真空中热处理杉木压缩木材(热处理温度范围140～220℃，时间范围0～36h)的明度、色差以及红外光谱。

In the production of low chrome cast iron grinding ball, there has been existing lower longevity and instability properties.

在低铬铸铁磨球生产上，一直存在磨球介质的使用寿命不高，性能不稳定。

First, the potassium bearing food, such as coarse grains, potatoes, nuts, banana, chufa, apricot, orange and milk, these foods are very help in relieving the brain fatigue and make the nerve transmitter work normally.

一种是含钾元素的食品：钾元素可直接连通大脑神经，可使大脑神经介质正常有序地工作，确保大脑轻松，粗粮、土豆、坚果、香蕉、荸荠、杏、柑橘、牛奶等富含钾元素。

EGCG was reported to inhibit leukocyte migration in response to chemokines such as IL-8, CINC and MIP-2, to trap reactive oxygen species, to inhibit neutrophil degranulation and inhibit inflammatory mediator release.

EGCG的抗炎作用涉及多个环节，包括抑制趋化因子如白介素-8(IL-8、细胞因子诱导的中性粒细胞趋化因子-1(CINC-1)、巨噬细胞炎性蛋白-2(MIP-2)等诱导的白细胞的定向迁移、清除氧自由基、抑制嗜中性粒细胞脱颗粒及炎性介质的释放等。

Level circular canal fixed under stator coil, 'lower circular canal' for short, is installed according to number of line bars to connect it with insulation draft tube via airproof parts, and to ensure coolant in line bar evenly distributed.

定子绕组下方配置的水平环管，简称下环管。按定子线棒数在环管上装设接口，经密封构件与绝缘引流管连接，以确保所有线棒中冷却介质的均匀分配。

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。
