采用固相萃取/高效液相/四极杆飞行时间串联质谱检测活性污泥中的全氟辛烷磺酸及全氟辛酸。

A new production process is proposed, in which the acid sludge is removed and the pickling liquor is neutralized once with lime milk after defluorination.

对我国化工企业现行的盐酸法饲料级磷酸氢钙生产工艺的现状进行了介绍与分析，指出了存在的问题，提出了一种新的生产工艺，即去渣一段中和法。

Carbon dioxide is produced when oily sludge and hydrochloric acid slug combinations are injected into porous media.

通过ICPOES、SEM等手段确定了污泥的主要组分为碳酸盐，其中含有菱形及球形碳酸钙颗粒。

The results showed that removal rates of five metals were 3.79%, 2.04%, 1.66%, 0% and 0%, respectively, under conditions of ultrasound time of 20 minutes. When nitric acid was added to the sludge, the removal rates were 2.32%, 40.67%, 68.15%, 26.98% and 27.24%, respectively.

结果表明，在超声时间为20分钟时，未加酸时五种重金属Cu、Zn、Pb、Cd和Cr的去除率分别为：3.79%、2.04%、1.66%、0%和0%，而加酸时其去除率分别为：2.32%、40.68%、68.16%、26.98%和27.24%。

Experimental results show that the reaction between hydrochloric acid and sludge under airtight condition is an equilibrium reaction, the reaction rate decreases exponentially with the increase of the initial pressure, the system gelling time increases with the decrease of the pH value, and the plugging performance of the waterglassgel enhanced foam system is superior to that of ordinary foam system due to the small foam diameter and high interfacial film strength.

实验结果表明：盐酸与污泥的反应在密闭条件下是一个平衡反应，且其反应速度随初始压力的增加呈指数降低；体系的胶凝时间随着pH值的降低而增加。由于体系的泡径小，界面膜的强度高，因而水玻璃凝胶增强泡沫体系的封堵效果明显优于普通泡沫体系。

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.
