讀個漢聲小百科，不代表你懂科學.......... 不要以為你讀漢聲小百科裡講太空梭的黑障區在30km高度結束 就代表速度更快的彈道飛彈彈頭也是，事實上電漿會一直糾纏 著彈頭直到落地為止，像下面這一副彈道飛彈落地的照片 http://www.fas.org/nuke/guide/usa/icbm/Peace_Reentry-kmr.jpg 若是沒有電漿，彈頭是不會拖著這種光尾的 然後，要形成低於5000k的低溫電漿，只需要低於100torr的低 壓就行，這時平均電子路徑夠長，電子能量無法有效傳遞，電 子溫度會遠高於氣體的動能溫度，要形成電漿簡單的要命 100torr高度大概要到十多公里，這個高度連一般戰鬥機都飛 得到，這個高度在大氣科學中可是非常的低 另外，不要讀完了漢聲小百科後就和小學生一樣看到電磁場就覺 得會有磁鐵，一般的氧電漿或是RIE、CVD之類機器的電漿產生器， 裡面沒有任何磁鐵，只有一堆線圈或行波管，你叫別人拔，我還 真不知道他要拆哪一個部位才拆得出磁鐵 用RF或是MW加熱只是因為加熱的比較均勻，低溫電漿用光或是熱 線也有辦法產生，更別提是炙熱的碳碳複材外殼 而就算是高度低於15km，電漿還是會被產生，雖然壓力高於100torr ，氣體溫度要等於電子溫度才會形成電漿，但是因為碳碳複材是 半導體，而且碳被磨耗時也會部份解離，所以還是會有電漿 如果你覺得在常壓下產生電漿事狗屁不合理的事，你可以到這個網站 http://blog.yam.com/user/SlavaRossii.html 你上去他的站貼文和他辯論，如果你辨倒他了，那我就承認你的觀點 ，如果沒有，那我還是繼續把你的講法當成狗屁 -- 諾貝爾和平獎的得主與航太工程師的不同之處在於... 前者只能打打嘴砲看看能不能打動想打仗的領導人和腦殘的追隨群眾
