铁矿石颗粒的直径越小，比表面积越大，也对反应越有利，而温度对Cr的去除影响不大。100目的褐铁矿颗粒去除Cr的能力为7.77mgCr/g。

The iron, in which the carbide has a high chemical stability and the matrix possess a matchable oxidation resistance, can be well resistant to abrasive wear at elevated temperature. In addition, the high temperature abrasive wear resistance of the high Cr—Ni cast iron containing eutectic carbide is much better than that of 0Cr26Ni14 heat resistant steel in which no carbide exists.

结果表明，M〓C〓型碳化物的高温化学稳定性对高Cr—Ni铸铁合金的抗高温磨料磨损性能有显著的影响，碳化物的高温化学稳定性愈好，基体的抗氧化性又能与之相匹配，合金的高温抗磨性就愈好；而且，含有碳化物的高Cr—Ni铸铁合金的高温抗磨性远优于不含碳化物的0Cr26Ni14耐热钢。

In this method, EDTA was used as complexant which can form 1∶1 complex with Cr〓, this complex carried negative charge and can be detected directly by UV absorbance at 200nm, therefore, the CrO〓 and Cr〓 can be separated and determined in one run.

The surface film formed at higher potentials consisted of oxides of Ni in predomination with some Fe and little Cr, while that formed at lower potentials was composed of oxides of Cr, Ni and Fe. The latter showed much higher resistance to caustic SCC.

这与较高电位下生成严重贫铬的Ni和Fe的氧化膜，而较低电位下生成由Cr、Fe、Ni的氧化物共同组成的表面膜密切相关。

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。
