n.不透明性；蔽光性

Saudi Arabia obscures its vulnerability by opaqueness. 沙特阿拉伯人以其神秘莫測(cè)來(lái)掩飾其脆弱。

Aerosol optical depth is a measure of the opaqueness of air, and high values of AOD indicate poor visibility. 氣溶膠光學(xué)厚度AOD量度大氣的透明度。高數(shù)值表示能見(jiàn)度較低。

Opaqueness, on the other hand, would hinder anticipation, adaptation, and evolution of complex vivisystems altogether. 相反，渾濁卻會(huì)完全阻礙復(fù)雜的活體系統(tǒng)的預(yù)測(cè)、適應(yīng)以及進(jìn)化。

There was also smog, or haze, or some version of atmospheric opaqueness for which the International Olympic Committee has yet to invent a word. 這兒也有霧，或者是霾，或者大氣不透明現(xiàn)象其他版本的說(shuō)法，為此國(guó)際奧委會(huì)仍然在絞盡腦汁尋找新的名詞。

But given the nature and scale of the Internet and the opaqueness of the Chinese authorities, it is extremely difficult estimate its extent. 網(wǎng)上流傳關(guān)于所謂政府隱瞞不報(bào)地震“預(yù)報(bào)”的陰謀說(shuō)，實(shí)際上經(jīng)不起推敲。
