查询词典 alkali grass

Transition probabilities, oscillator strengths, and lifetimes of configurations, multiplets, and individual lines for many-electron atoms and ions are studied employing the WBEPM theory. Transition probabilities and oscillator strengths for alkali metal atoms, alkaline-earth elements Be, Mg, Be , and Mg , carbon atoms and its ions , nitrogen atom and its ions , oxygen atoms and its ions , fluorine atom, Ne , and IB elements are calculated. Lifetimes of C, N, and O atoms are evaluated as well.

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
