Meanwhile , from the compact disk ( cd ) to today ' s digital versatile disk ( dvd ) and the coming blue - ray disk ( bd ) , optical disks , which are based on two - dimensional metallic gratings , are perhaps one of the most successful and hopeful media for high - capacity and high - density information storage 在信息存儲(chǔ)領(lǐng)域,從cd到今天的dvd以及未來(lái)的藍(lán)光光盤(pán)( bd ) ,基于二維光柵衍射的光盤(pán)存儲(chǔ)是高容量高密度信息存儲(chǔ)的最成功并最具潛力的技術(shù)之一。
The most significant advantages of the electrostatic suspension are as follows : ( i ) it keeps the characteristic elegance of the conventional electric suspension methods mentioned above ; ( ii ) it is capable of realizing electrostatic levitation of conductors , semi - conductors and non - conductors , such as the liquid crystal display ( lcd ) , the compact disk ( cd ) , the silicon wafer and so on ; and ( iii ) it provi des the possibility of implementing non - contact conveying or manipulation of precision objects on the basis of suspension 利用該懸浮方法可以廣泛實(shí)現(xiàn)導(dǎo)體(如金屬片) 、半導(dǎo)體(如硅wafer ) 、常規(guī)絕緣體或電介質(zhì)(如lcd片、 cd片、玻璃片、紙片)等懸浮,進(jìn)而對(duì)其進(jìn)行非接觸的無(wú)損操作。與常規(guī)電懸浮和磁懸浮相比,靜電懸浮的突出優(yōu)點(diǎn)是不受懸浮體的磁性和導(dǎo)電性的制約,因而應(yīng)用領(lǐng)域更加廣闊。
