LiNi0.95Mg0.05O2 could be formed with I(003)/I(104) ratio 1～1.1, R-factor I(006+I(102)/I(101) ratio 0.67～0.94, and (108)/(110) splitted peak, c/a ratio 4.914～4.925, in R3m space group under the conditions of 210~280 MPa pelletized powder, heating rate 2℃/min to precalcined temperature 600℃ for 9～15h,crushed and repelletized, heated till 600℃ in 5℃/min, then switched to 1℃/min till 750℃ isothermally for 15～20h all in oxygen flow.

发现以210～280 MPa对试样压片，在氧气气氛下经2℃/min升温速率升温至600℃，预烧9～15h后，再粉碎、压片以5℃/min升温至600℃之后以1℃/min升温至750℃恒温15~20h，可得I(003)/I(104)峰比值1~1.1，R-factor I(006+I(102)/I(101)峰比值0.67~0.94，并且有(108)与(110)的分裂峰，同时c/a比值4.914~4.925，属于R3m空间群的锂镍镁氧化合物。

Generally the catalysts have high activity and good selectivity. At present the coupling reactions of organoborahes with terminal olefins s acid chlorides and aryl halides play an important synthetic approaches in organoborane chemical. The catalysts can be used by many kinds of organometal compounds such as: irons cobalt nickel ruthenium rhodium palladiums titaniums zirconiums tins indium and lithium organic compounds; The achievement has been amazed in preparing of unsaturated or saturated compounds and in synthesizing of natural products bioactive molecules and chiral compounds.

目前，卤代烃与不饱和烃的偶联反应和有机硼试剂与酰卤和卤代烃的偶联反应已成为有机合成的研究热点，此类反应可用铁、钴、镍、钌、铑、钛、锆、锡、铟、锂等多种有机金属化合物来催化，用于形成含饱和或不饱和C-C键的化合物，并已在天然产物、液晶、具有生理活性物质和手性化合物的合成中应用。

Nitrogen is inert except when heated to very high temperatures, where it combines with some of the more active metals, such as lithium and magnesium, to form nitrides.

一般情况下，氮是不活泼的的。当加热到非常高的温度时它会同更加活泼的金属，如锂和镁反应生成氮化物。

Do not use lithium ion , nickel cadmium nicad , or carbon zinc batteries .

第三条：只使用碱性电池，不要使用锂电池，镍镉电池，碳素电池，锌电池。

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。
