The trickiness about the reaction is that tritium doesn't exist in nature.

关於反应的棘手处是－氚不存在於自然界中，你必须由别的东西来制造它；你可由锂来制造它。

Lithium batteries as a result of no memory, so do not worry in case of power under the charge of battery life.

由于锂电池没有记忆性，所以不用担心在未满电的情况下充电而使电池寿命减少。

Founded in 1999, under the crown of Hong Kong Lee Holdings Group, is a development, production, sales lithium-ion battery into a high-tech enterprises.

深圳环宇达电池科技有限公司成立于1999年，隶属于香港冠利控股集团，是集研制、生产、销售锂离子电池为一体的高科技企业。

The effects of yttrium on the charge-discharge behaviour and surface structure of lithium-aluminium alloy anode were studied.

Methods 54 Wistar rats were injected abdominally with lithium by 6 different periods later within 3 days, different dose of pilocarpin was injected.

54只wista大鼠腹腔注射氯化锂3mmol/kg，在三天内分六个时间段给予不同剂量的匹鲁卡品腹腔注射。

Rats in the diazepam intervention group were injected abdominally with diazepam 30 minutes before pilocarpine injection.

干预：实验组幼鼠采用氯化锂-毛果芸香碱腹腔注射制成幼鼠癫痫持续状态模型，生理盐水对照组以相同液体量的生理盐水取代毛果芸香碱。

It starts with an aldol-type condensation in which a solution of the now commercially available E -[3-(4-fluorophenyl)-1-(1-methylethyl)-1 H-indol-2-yl]-2-propenal, 4 , 5 in THF is added to the preformed sodium-lithium salt of tert -butyl acetoacetate 5 at room temperature in THF.

它从一个醛型缩合其中一个解决现在的电子商业可-[3-(4-fluorophenyl)-1-(1-methylethyl)-1吲哚-2-基]-2-丙烯醛、4，5年增加了预四氢呋喃钠-锂盐叔丁基乙酰四氢呋喃在常温5。

Recently , people find that LiMPO_4 is the anodal material of potential lithium ion battery with the above fine performance .

最近，发现LiMPO_4是具备以上优良性能的潜在锂离子电池正极材料。

The total synthesis of the title compound 10 was accomplished starting from 3,5-dimethoxybenzoic acid (1) and p-hydroxybenzaldehyde (6). In the process, esterification, reduction, bromination and Wittig-Homer reaction were performed.

以3，5-二甲氧基苯甲酸为起始原料，经过甲醇酯化、氢化铝锂还原、四溴化碳溴代和Wittig-Homer反应，高产率的合成了Wittig-Homer试剂(5)。

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。
