The conclusion is conformed by microprobe analysis, which also shows that the purplish-red type is higher in Cr while the brownish-red garnet is richer in Fe and Ti.

This means that the residual strain in rolled alloy promoted the aging process. The influence of aging temperature on the room-temperature mechanical properties of 1〓, 2〓 and 6〓 alloys was tested and the results show that the 1〓 alloy without minor element additive is very sensitive to the aging temperature. Over-aging occurred easily when the aging temperature is somewhat higher, so it is difficult to control the aging treatment in production. The 6〓 alloy with combined Mg, Cr, Co additives showed less tendency of over-aging, the alloy can be aged in a wider temperature range and the mechanical property is stable. So the treatment process can be easily controlled.

对不同微量添加元素的1〓、2〓和6〓三种合金经热轧态时效后的室温力学性能表明，不添加微量元素的1〓合金对时效温度较敏感，温度偏高时容易产生过时效，且过时效的温度明显低于加Mg的2〓合金和同时加Mg、Cr、Co的6〓合金，这对生产过程中的工艺控制增加了难度，6〓合金的过时效倾向最小，合金可以在较宽的温度范围内进行时效，力学性能较稳定，使生产工艺较易控制。

Ni, Cr, W, Mo, Al, Ti, B and misch metal were added separately or in combination into pure iron containing 0.166% of oxygen. Optical and chemical properties as well as crystal structure of various types of nonmetallic inclusions present in the alloys were studied.

在含氧纯铁中，分別并按组合方式加入Ni，Cr，W，Mo，Al，Ti，B和混合稀土金属，然后利用金相法、岩相法、X射线粉末法和夹杂物的组成定性分析等方法研究了这些脫氧产物的光学性质，化学性质和晶体结构。

The influence of Mn on the reduction of Cr by the three organic acids was also studied.

同时研究了Mn对3种α-OH酸还原Cr反应速率的影响。

Preparation of the cross-linking mycelium and its adsorption characteristic to Cr^3＋ were studied.

深入研究了交联菌丝体吸附剂的制备工艺及其对Cr^3＋的吸附特性。

The NaAA and LiAA could improve the properties of CPE, NBR, EPDM, CR, NR, SBR and BR.

此外，尼尔森在线还可选择将CR-Nielsen在美国上市。

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。
