酸性

Effects of water quenching on properties of pyrrhotite in calcines of Huangjingdong concentrates are examined using TG-DTA techniques.

回转窑焙砂中的硫主要以磁黄铁矿形式存在，在高温及酸性气氛下直接水淬冷却时。

Therefore, the rapid oxidation of pyrrhotite contributes to a great extent to the contamination of environment in tailings through the production of acid mine drainage AMD. In order to ...

为了阻止或降低磁黄铁矿的自然风化反应速度从而达到源头治理酸性矿山废水的目的，首先必须研究它在各种条件下的氧化机理、氧化产物和氧化速度。

By way of quadrature analysis, the optimal condition of microwave Ti02-photocatalysis was found.

在最优化条件下处理酸性大红废水的降解率可达90%以上。

An acid-test of 1:1 is considered satisfactory unless the majority of your "quick assets" are in accounts receivable, and the pattern of accounts receivable collection lags behind the schedule for paying current liabilities.

酸性试验为1：1相当满意，除非你大部分"快速资产"是应收帐款、应收帐款及收款方式落后时间表缴纳流动负债。

The Quick Ratio is sometimes called the "acid-test" ratio and is one of the best measures of liquidity.

快速比率有时被称为"酸性试验"就是一个最好的比率和流动资金措施。

Process the Quicklime Mixture and the Acidic Mixture with the Amalgamating Machine in Factory Bay B.

将石灰化合物和酸性化合投入到工厂B区的搅拌机中，随后你就将得到可燃的化合物。

Catalyst acidity and hydrogen donating abilities of hydrocarbon solvent had marked effect on quinoline cracking.

催化剂的酸性、烃类溶剂的供氢能力对喹啉裂化有显著影响。

Extraction of quinoline from wash oil by using macro porous strong acid ion exchange resins was discussed.

对大孔型强酸性阳离子交换树脂提取煤焦油洗油中的喹啉进行了初步探讨。

Separation of enantiomer for the acidic racemate could be improved with a lower pH value of the mobile phase since the dissociation of acidic compound was impressed, but it did not affect significantly the resolution of neutral compounds.

在流动相中使用低pH值，能有效抑制酸性化合物的解离，从而显著增强其手性识别能力；对于中性化合物，流动相中pH对手性分离影响不大。

This intermediate is responsible for the stereoselective nucleophilic substitution and the subsequent racemization of 3-EtO-NDZ enantiomers in acidic ethanol.

该中间体导致了3-EtO-NDZ对映异构体在酸性乙醇中所发生的立体选择性亲核取代反应及随后的消旋过程。

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.
