科技英文 問題

1.The larger the conductor, the more it spreads out. In the case of a very large object, the charge can spread out so much that any chunk of the object has a negligible amount of charge and hence, behaves as if were neutral. Near the surface of the earth, the earth itself is large enough to play such a role. If we bury a good conductor such as a long copper rod or pipe, in the earth, and connect to it another good conductor such as a copper wire, which we might connect to another metal object, such as a cover plate for an electrical socket, above but near the surface of the earth, we can take advantage of the earth’s nature as a huge object made largely of conducting material.

找出以上文章.名詞.副詞.單數複數.形容詞.動詞.還有全文翻譯

和縮寫意思!!

誰能幫幫忙阿~很急~自己搞不定

    愈大的導體,電荷的範圍愈廣。以一個非常大的物體來說,電荷的分佈是如此的廣,以致於物體的每個部份所帶的電荷少得好像是不帶電一樣。地球的表面也是如此,地球本身就大得可以,如果將一個良性導體如長銅桿或長銅管埋進地球裏,再連結另一個良性導體如銅線,再連結到另一個在地球表面上方的金屬導體,如帶電插座的覆蓋板上,我們就可以利用地球的本質,把它當做一個可導電的大型導體。

  • 1 ,大的導體,它的更差了。對於一個非常大的對象,可以分散收取這麼多,任何塊的對象有一個微不足道的金額收取,因此,表現為,如果是中性的。近地球表面,地球本身是大到足以發揮這樣的作用。如果我們埋葬了良好的導體,如長期銅桿或煙斗,在地球,並連接到它的又一個好導體如銅線,我們可能會連接到另一台金屬物件,如蓋板的電器插座,但上述接近地球表面的,我們可以充分利用地球的性質作出了巨大對象主要是導電材料。
