DSC-TGA thermal analysis and XRD characterization results demonstrate that Fe is precipitated as Fe3O4 during alkaline decomposition of jarosite. The contents of Fe, In and Zn in decomposition residue are 38.81%, 0.23% and 12.89%, respectively. After selective leaching of In and Zn with dilute HCl solution, the iron concentrates obtained from magnetic separation can be used as raw material for iron smelting.

They then added a dilute concentration of potassium chloride to one protocell and a more concentrated solution to the other.

然后他们向其中的一原细胞加入稀释的氯化钾，向另一个加入一样但浓度较高的。

Place in a 250 ml conical flask fitted with a ground-glass stopper, 10.0 ml of the solution, 50 ml of water R, 12 ml of dilute acetic acid R and 3 g of potassium iodide R.

滴定 在250ml的带磨砂玻璃塞的锥形瓶中，加入10.0 ml的此溶液，50ml的水，12ml的稀乙酸和3 g的碘酸钾。

It has been observed that pyrocatechol and m-phenylenediamin can sensitively inhibit the discoloration of neutral red oxidation by the H2O2 and in the presence of catalyzer Fe in dilute sulfuric acid solution but the inhibitory effects of two organic compounds can not be added. Based on this research, the advantages of artificial neural network were adopted to handle the experimental data and a new inhibitory kinetic spectrophotometry of simultaneous determination for pyrocatechol and m-phenylenediamin with artificial neural networks was established.

在硫酸性介质中，Fe能够催化H2O2氧化中性红褪色反应，邻苯二酚和间苯二胺都能阻抑该催化氧化褪色反应的速度，研究发现：两者对Fe催化H2O2氧化中性红褪色反应阻抑作用不具有加和性，根据这一现象，用人工神经网络处理非线性体系的优势进行数据处理，从而建立了一种新的测定邻苯二酚和间苯二胺混合物的人工神经网络阻抑动力学光度法。

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。
