The specific surface area of catalysts decrease with the increase of calcining temperature and the Cu content of catalyst.

催化剂的比表面积随焙烧温度的升高和催化剂负载的铜含量增加，其比表面积下降。

Generally, every pound of food waste to be composted per week will require 1 square foot of surface area.

一般来说，每磅食物渣滓可堆肥每星期将需要一平方英尺的面积。

The components of the catalyst are sulfurated more completely with a longer reaction time. But the catalyst congregates into a large volume ball with a low BET surface area after a certain reaction. So the best range of reaction time is from 60 to 90 minutes.

研究发现，虽然硫化时间的延长可提高催化剂中金属组分的硫化物含量，但超过一定反应时间可导致硫化物过度结晶聚集，颗粒度增大，比表面下降，较佳的反应时间为60～90 min。

It is on the large surface area provided by the inner cristae of mitochondria that ATP-generating

线粒体自我复制，并且可能是自由生活的原核生物在进化中形成的后代。

It is on the large surface area provided by the inner cristae of mitochondria that ATP-generating enzymes are located.

ATP 产生酶存在于线粒体上内质体的巨大表面上。

The results show that the sample prepared by coprecipitation method exhibits the highest activity and has the largest crystallite size, and after reaction for 140 min, 53.6% of rhodamine B is decolored; while for catalyst prepared by the citric acid complexation, the decoloration ratio is only 9.0%, though the latter has a higher surface area and smaller crystallite size than the former.

研究结果表明：这4种方法均能制备单一的钙钛矿型LaFeO3催化剂，其中，共沉淀法制备的催化剂具有最大的晶粒尺寸，最小的比表面积，仅为0.4 m2/g，显示出最强的光催化活性；在可见光照射下反应140 min，罗丹明B的脱色率达到53.6%。柠檬酸络合法制备的催化剂的比表面积最大，为8.1 m2/g，但其脱色率仅为9.0%。

Our products are characterized by strong decoloring power, large specific surface area, strong adsorptive power, low impurities and effective filtering etc.

我公司引进设备生产的活性炭产品，具有脱色能力强、比表面积大、吸附能力好、杂质含量低、过滤速度快、选择性强等特点。

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.
