We have used GC to follow up the formation of epoxy acid and established the acidify condition; we have done series of parallel experiments to better the pivotal condensation reaction between acid and amine; In the cyclization step, we use cheap and available reagent-Lithium amide , rather than expensive LiHMDS, to proceed the reaction; and at last, we introduced green reagent-ozone to clear the phenyl group of nitrogen to avoid using heavy metal reagent-CAN. The total yield for this method is 29.8%.

随着热处理温度的升高，β-石英固溶体转变成β-锂辉石固溶体，而且微晶玻璃相应的变为不透明的乳白色，同时红外光谱可以检测到Al—O键的配位状态，且温度越高，Al—O键所占的比重越大。

The research indicate that the performance of brazing joint using Al-Ge-Si brazing filler metal precedes to the one using HL401 brazing filler metal. And the main reason is that brittle compound such as Cu2Al is not appeared in brazing joint.

The results indicated that the adsorbance of adsorbed CO in the presence of alkali and rare-earth metal oxide decreased, and thus suppressed the nick loss in the form of Ni〓 in the POM process.

CO-FTIR的结果表明，锂和镧的添加可明显减少CO在NiO/γ-Al〓O〓上的吸附，从而抑制反应过程中羰基镍的生成和流失，同时也抑制了CO的歧化积碳和在表面进一步氧化成CO〓。3。

In this study, as a original strain, antagonistic bacterium Ata28 was mutated by UV, UV+LiCl, DES and Microwave irradiation; the very goal of the research is to improve the control efficiency of Ata28 strain against tobacco brown spot and obtain strains advanced both in antagonism and biological characteristics, further provides theoretics and practical experience to the production.

采用紫外线和氯化锂复合诱变Ata28菌株，通过预备实验，计算Ata28菌株在不同诱变时间的致死率和正变率，选择该菌株的最佳诱变时间10s，15s诱变；通过平板对峙培养，筛选出8个突变菌株在PDA平板上可明显抑制Tbs3的生长，抑菌带高于出发菌株Ata28，抑菌带最大值达9.7mm；经温室控病初筛和复筛试验，获得了对烟草赤星病有较好防效的突变菌株Uv1-190、Uv1-199，烟苗经Uv1-190、Uv1-199菌液处理3d后，接种Tbs3的防治效果达51.3％、54.9％，比出发菌株Ata28的防治效果好。

The liquid electrolytes at the heart of traditional lithium-ion batteries can catch fire, but the Fraunhofer scientists say they've figured out a way to make them with a new, solid polymer that's inflammable, and, since it's solid, won't leak.

在传统锂离子电池的中心的液态电解液能着火，但Fraunhofer的科学家说他们已想出一种方法，用一种新的不可燃的固体聚合物来制造电池，并且由于是固态的，不会泄漏。

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。
