酸性的

The reason given was that the acid in the orange juice would make the milk curdle and become indigestible.

所给出的理由是桔汁中的酸性物质会使牛奶变成凝乳状而难以消化吸收。

The paper discussed release possibility of toxic and harmful elements during gold mining.It presented the major envi-ronmental problems that are cyanidation setups and Acid Mine drainage during gold mining.

本文主要对金矿开采中有毒有害元素的释放进行了探讨，明确了在金矿开采过程中主要的环境问题是氰化物堆浸和酸性矿坑排水问题。

If your body is overly acidic, your cells cannot detoxify.

如果你的身体过於酸性，您的细胞不能解毒。

Amino-5-acety laminobenzenesulfonic acid has been synthesized from 2, 5-diaminobenzene sulfonic acid and Acid Red BG (CI Acid Red 37) has been synthesized by coupling the diazonium salt of 2-amino-5-acetylaminobenzenesulfonic acid with racid.

利用2，5-二氨基苯磺酸为原料合成2-氨基-5-乙酰氨基苯磺酸，并进一步经2-氨基-5-乙酰氨基苯磺酸重氮盐与γ酸的偶合反应合成了酸性红BG（CIAcidRed37），并对影响反应的因素进行了讨论

The conversion of methanol is higher than 98% and the selectivity of dimethylamine is higher than 62% at 320～340 ℃ and 1.8～2.0 MPa.

目前 ，工业上用于甲醇气相氨化制备甲胺的催化剂是具有脱水和氨化作用的酸性催化剂，如γ-Al2 O3、硅酸铝、氧化钍等。

In the presence of the combination of sulphuric and phosphoric acid, with sodium diphenylamine sulfonate as the indicator, standard solution of potassium dichromate was used to titrate total iron value.

试样以盐酸溶解后，在酸性介质中，先以氯化亚锡将三价铁大部分还原为二价，然后在钨酸钠指示下，再以三氯化钛将剩余的三价铁还原为二价，过量的三氯化钛以重铬酸钾氧化消除干扰，在硫磷混合酸存在下，以二苯胺磺酸钠为指示剂，用重铬酸钾标准溶液滴定全铁量。

Its acidic dissociation constant at ground and excited state are determined based on the changes of the absorption and fluorescence spectra in the water.

基于不同pH值水溶液中吸收和荧光光谱的变化，计算得该试剂基态和激发态分子的酸性常数（pKa＝ 8.84， pKa＝ 5.11）。

Pyrex glass is probably the best container for hot acid; I have also used a plastic container held within a metal pot as a "double boiler" for heating specimens in acid.

高硼玻璃也许是最佳的集装箱热轧酸，我又用一个塑料容器内举行的一个金属罐作为"双锅炉"，为供热标本，在酸性。

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。
