They are commonly measured in units of biochemical oxygen demand, or the amount of oxygen needed to decompose them

常常使用生化需氧量，即有机物分解所需的氧这个单位进行测量。声音的响度可以测量。

They are commonly measured in units of biochemical oxygen demand, or the amount of oxygen needed to decompose them

常常使用生化需氧量，即有机物分解所需的氧这个单位进行测量。

The most common of these measures are biochemical oxygen demand and chemical oxygen demand.

并且氧气被用作有机物的分解同且用作实物。

Biochemical Oxygen Demand is an important control index in wastewater effluent ,but it takes longer time(5 days)for its determination,while the time for measuring the Chemical Oxygen Demand is shorter(10 hours).

生化耗氧量是废水排放的重要控制指标，但它的测定需要时间较长，而化学耗氧量的测定时间较短，这两者是否存在稳定的关系？

Generally aerobic and anaerobic wastewater treatment plants require substantial areas of land for the effective treatment of liquid waste streams to achieve very low levels of Biochemical Oxygen Demand and Chemical Oxygen Demand reduction.

通常，好氧和厌氧的废水处理设备需要大量土地以进行有效的废液处理，把生化需氧量和化学需氧量减少到非常低的程度。

The oxygen consumed,or biochemical oxygen demand,is proportional to the organic matter converted ,and therefore BOD is a relative measure of the biologically degradable organic matter present in the system .

氧消耗量，或生化需氧量，是成正比的有机质转换，因此，生化需氧量是一个相对的措施，生物可降解的有机物，目前在该系统。

Biochemical oxygen demand over five days - BOD5: The standard biochemical oxygen demand test whereby a sample of the liquid is incubated at 20 degrees C for five days.

五天生化需氧量(简写为BOD5)：标准的生化需氧量试验。其方法是把一份溶液的样品在摄氏20度下培养五天。

The results showed that the IVCW effectively removed total suspended solids(85%),chemical oxygen demand(50%),five-day biochemical oxygen demand(44%),total ammonia(53%),nitrite(83%) and nitrate(54%) from the aquaculture wastewater at a hydraulic loading rate of 420mm/d.

结果表明，在420 mm/d的水力负荷下，湿地可有效地去除循环水中的总悬浮物(去除率85%)、CODCr(去除率50%)、BOD5(去除率44%)、总氨氮(去除率53%)、亚硝酸盐(去除率83%)和硝酸盐(去除率54%)，能够满足养殖用水的要求，整个试验期间系统实现了零污水排放。

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。
