關(guān)于電力線的討論

全文約4300字 論述翔實

摘 要

電力線諸性質(zhì)是描述電力線圖象的依據(jù)，運用電力線還可以定性的分析一些易產(chǎn)生混亂的問題，也可以為運用求解靜電場的方法奠定必要的基礎(chǔ)，只要與靜電平衡條件下導體的性質(zhì)配合得當, 還是定性，定量分析與討論靜電平衡問題的有利工具。本文從電力線的概念出發(fā)詳細論述并證明了電力線諸性質(zhì)，并從電力線在描繪特殊電場中，在靜電平衡問題中，在使用高斯定理求場強方面，使用鏡像法求解問題及在理解靜電場性質(zhì)等五個方面的作用詳述了電力線的應(yīng)用問題。

關(guān)鍵詞：電力線，靜電場，電力線性質(zhì)

Discussion on Power Line

Abstract

Various properties of power line not only are a basis that describes the electric power line image, but also establish base for solving electrostatic field. Using power line can analyze questions that puzzle easily people. Combining features of conductor on static equilibrium condition, power line is the beneficial tool that analyze qualitatively or quantitatively static equilibrium problem. The article gave a detailed treatise on various properties of power line. Application problems of power line were discussed from a few aspects that describing the special electric field, solving density of filed using Gauss axioms, doing problem using mirror method and understanding properties of electrostatic field.

Key words: Power line; Electrostatic field property; Property of power line
