如鋼鐵企業(yè)中高爐的高風(fēng)溫、火風(fēng)量操作和高爐的大型化;在煉鋼連鑄方面，轉(zhuǎn)爐和電爐煉鋼技術(shù)進(jìn)步，特別是高功率和超高功率電爐的不斷提高。在建材行業(yè)，如浮法玻璃生產(chǎn)工藝的不斷發(fā)展和玻璃溶池的大型化，以及對(duì)國外先進(jìn)窖爐的引進(jìn)等。
且不說此舉耗用大量的可耕地和運(yùn)輸費(fèi)用，還會(huì)給環(huán)境造成長遠(yuǎn)的破壞。值得注意的是國外經(jīng)濟(jì)發(fā)達(dá)國家都對(duì)廢棄物的管理和廢物再利用進(jìn)行了立法，有了一套完整全面的措施政策和法律，使廢棄物再利用有了法律保障和支持，并且享受國家政策上的優(yōu)惠，這就客觀上起到了積極倡導(dǎo)的作用。
比表面積的單位為或。比表面積與粒度有一定的關(guān)系，粒度越細(xì)，比表面積越大，但這種關(guān)系并不一定是正比關(guān)系。
