adj.不起反應(yīng)的

Elemental nitrogen is a very unreactive and inert material. 元素氮是一個(gè)十分不活躍的惰性物質(zhì)。

The material is unreactive chemicals and thus does not radiate much radiation. 該材料是非活潑化學(xué)物，因此并沒(méi)有輻射。

One of the noble gases, neon is colorless, odorless, tasteless, and completely unreactive. 氖是稀有氣體的一種，無(wú)色、無(wú)臭、無(wú)味，完全不起化學(xué)反應(yīng)。

The heaviest noble gas, it is colourless, odourless, tasteless, radioactive, and almost completely unreactive (forming compounds only with fluorine). 氡是最重的稀有氣體,無(wú)色,無(wú)臭,無(wú)味,有放射性,相對(duì)不活潑(只與氟組成化合物)。

The first concerns noble gases.Were it not for escape, chemically unreactive gases such as neon or argon would remain in an atmosphere indefinitely. 第一個(gè)線(xiàn)索與惰性氣體有關(guān)，氖或氬這類(lèi)的惰性氣體不會(huì)散逸也不會(huì)進(jìn)行化學(xué)反應(yīng)，會(huì)長(zhǎng)久存在大氣中。
