To improve the electrochemical performance of LiFePO4, the high temperature solid-state reaction method with two-stage sintering assistant by milling was used to synthesize the LiFePO4/C composite cathode materials by doping different carbon sources (Sucrose, Coal tar asphaltum and Coal tar asphaltum after improving-identifier "M").

为了提高LiFePO4的电化学性能，采用球磨辅助分段焙烧高温固相法，在前躯体中掺入不同的碳源（蔗糖、煤焦油沥青、改性后的煤焦油沥青－标记为M），合成了锂离子蓄电池LiFePO4/C正极材料。

Precursor LiMgxMn2-xO4 is prepared by the method of phase transfer, and then the precursor is sintered in the air astrosphere at a certain temperature for a certain time to get cathode material for lithium ion battery.

利用相转移法合成了LiMgxMn2-xO4前驱体，在电炉中于一定温度下烧结一定时间，得到锂离子电池正极材料粉体，并利用XRD、SEM、IR等对材料粉体进行结构形态表征。

Built-in lithium battery is only for testing and automatic reset of the auxiliary power supply, its life as long as 15 years.

内置的锂电池只作为测试和自动复位的辅助电源，其使用寿命长达15年。

So, the design of stable, safe, reliable, high-performance lithium battery charger is particularly important.

Olivine-type LiFePO4 are recently expected to have a bright future as a potential cathode material of large scale moveable lithium ion batteries for its high theoretical capacity(170 mAh/g)and voltage(about 3.5 V versus Li/Li+),good stability both at room temperature and high temperature,low cost and environmental benignancy.

橄榄石型LiFePO4具有170 mAh/g的理论比容量和约3.5 V的电压、较好的常温和高温稳定性、低廉的价格和优良的环保性能，有望作为大型移动式锂离子电池的正极材料。

Therefore, it has significance to optimize the demodulation curve. By the use of expansion of Bessel function and optical field overlapping method, the relation between the demodulation curve and the resonant frequency deviation was analyzed.

利用贝塞尔函数展开和光波场叠加的方法分析了谐振式光纤陀螺调相检测系统解调输出信号与谐振频率偏差之间的关系，系统采用的是带有铌酸锂相位调制器的相位谱检测技术。

METHODS 3-methoxy-7α-methylestra-1,3,5(10)-trien-17β-ol was reducted with lithium and ammonia,then the intermediate was hydrolyzed in oxalic acid and reacted with malonic acid to get 3,3-dimethoxo-7α-methylestra-5(10)-en-17-ol(compound 4),which was oxidated by pyridium bichromate ,reacted with acetylene,and hydrolyzed in oxalic acid again to get the product tibolone.

In the present study, we investigate the effect of lithium treatment on mitochondria biogenesis in C6 glioma cells.

本研究利用C6神经胶瘤细胞探讨锂盐刺激对粒线体生合成作用的影响。

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。
