查询词典 acid value

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。

The 60% H 2 SO 4 is used to produce ammonium sulfate and fertilizer, reducing the production cost. After counteracting with alkali to keep pH Value to be 6.5 ～ 7, the acid tar is conjugated in proportion with anthracene oil and heavy benzene to mixed oil or fuel oil.

稀硫酸用于硫铵和普肥生产以降低生产成本；酸焦油与碱中和 pH 值达到 6.5 ～ 7 后，与蒽油或重苯按一定比例配成混合油和燃料油。

Electroless Ni-Co-Fe-P alloys were deposited from a soft alkaline bath, containing boric acid as a buffer agent and sodium citrate as a complexing agent. The effect of the bath pH value on the coating structure was investigated by energy-dispersive X-ray spectral analysis, scanning electron microscope and X-ray diffractrometry.

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。
