Low levels of the crust, melting point 3180 ℃, boiling point 5627 ℃, the relative density of 2053, the external F electronic structure 5d56s2, reaction time will be lost 1-7 electronic, but also can capture an electron, so oxidation number of 0,± 1, 2 , 3, 4, 5, 6 and 7, rhenium with the halogen in the fluorine, chlorine, bromine reaction halides dissolved in water, can dissolve in nitric acid and ammonia hydrogen peroxide solution, but do not dissolve in hydrochloric acid.

地壳中含量很低，熔点3180℃，沸点5627℃，相对密度2053，外围F 电子结构5d56s2，反应时会丢失1—7个电子，也可捕获一个电子，所以氧化数为0、±1、＋2、＋3、＋4、＋5、＋6和＋7，铼能与卤素中的氟、氯、溴反应生成溶于水的卤化物，能溶于硝酸和含氨过氧化氢等溶液，但不溶于盐酸。

The electron transfer rate of carbon nanotube field emission hopping electron cathode has been studied with experimental method.

对应用碳纳米管场发射的跳跃电子阴极的三极管结构的电子通过率的研究，提出了的栅网上蒸镀高二次电子发射系数的介质膜的方法，可以有效地解决栅网的截获问题，提高电子通过率。

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.
