元素形成 meaning in English
elementary form
Examples
- When several rare earth elements or rare earth with titanmium , zirconium were doped together , they form composite oxides
当添加多种稀土元素时则形成复合氧化物。稀土元素还可和钛、锆等元素形成复合氧化物。 - The ratios of the different isotopes differ depending on where and how an element was formed , and are therefore an important clue to the conditions of the element ' s formation
不同同位素的比例不同与元素在何时何地形成的有关，因此这是元素形成环境的重要线索。 - The aluminates are used as the base and the rare earth materials are used as the luminescence center and trap center . the excitation resource can be visible light and man - made light
它以铝酸盐陶瓷材料为基质，以稀土材料作为掺杂元素形成发光中心和陷阱中心，激发光源可以为目光或人造光源。 - And even if it could , it would not really help explain the origin of life , because the time available since the formation of carbon is only just over double the age of the earth
而且即使它能够，那也不一定对诠释生命的起源真的有所帮助，因为自碳元素形成以来可用的时间不过是地球年龄的两倍多一点。 - The aluminates are used as the base and the rare earth materials are used as the luminescence center and trap center . the excitation resource can be visible light and man - made light , so this type of long persistent phosphor has the advantages of no - radiation and no need of electricity
它以铝酸盐陶瓷材料为基质，以稀土材料作为掺杂元素形成发光中心和陷阱中心，激发源可以为日光或人造光源，无污染，不消耗电能，是一种高效节能的固体发光显示材料。
