Lub hauv paus ntsiab lus ntawm cov ntaub thaiv hluav taws xob
Yog tias tus neeg xyuas pib muab tso rau hauv ib qho hluav taws xob sab nraud nrog lub zog hluav taws xob lub zog ntawm etawm, Cov hluav taws xob siv hluav taws xob dawb hauv tus neeg saib xyuas yuav tsiv tawm tsam cov kev taw qhia hluav taws xob hauv qab cov hluav taws xob teb. Yog li, tus nqi tsis zoo tau faib rau ib sab ntawm tus neeg xyuas coj tus neeg xyuas, thiab tus nqi zoo rau lwm sab; Qhov no yog qhov tshwm sim ntawm electrostatic induction. Vim kev faib tawm ntawm kev them nyiaj nyob hauv tus thawj coj, cov nqi no rau lwm lub chaw ntim hluav taws xob hauv qhov chaw sab nraud, nrog hluav taws xob teb lub zog. Raws li lub ntsiab cai ntawm superposition ntawm hluav taws xob teb, hluav taws xob teb lub zog hauv tus neeg saib xyuas yog sib npaug ntawm etawmthiab ehauvCov. Thaum tag nrho hluav taws xob teb lub zog sab hauv tus neeg saib xyuas yog xoom, cov hluav taws xob hluav taws xob dawb sab hauv tus neeg kos duab tsis txav. Hauv physics, lub xeev uas tsis tau them nqi nyob hauv tus neeg xyuas pib yog hu ua electrostatic erdilibrium. Hauv ib tus neeg saib xyuas hauv Electrostatic etrilibrium, hluav taws xob teb lub zog sab hauv yog xoom txhua qhov chaw. Yog li ntawd, nws tuaj yeem txiav tawm hauv cov neeg xyuas hauv xov tooj hluav taws xob hauv electrostatic etrilibrium, tus nqi tsuas yog muab faib rau ntawm tus neeg xyuas sab nraud. Yog tias tus neeg xyuas no yog hollow, thaum nws mus txog electrostatic etrilibrium, tseem yuav tsis muaj hluav taws xob teb sab hauv. Yog li, lub plhaub sab nraud yuav "tiv thaiv" nws sab hauv, ua rau nws tsis muaj kev cuam tshuam los ntawm hluav taws xob sab nraud; Qhov tshwm sim no tau hu ua electrostatic kev thaiv.
Cov tswv yim tseem ceeb ntawm cov ntaub thaiv hluav taws xob: Tiv thaiv tiv thaiv ib puag ncig lossis ib puag ncig ua haujlwm hauv cov hluav taws xob saib xyuas, tiv thaiv lawv los ntawm kev cuam tshuam los ntawm lawv. Qee cov khoom siv hluav taws xob lossis cov khoom siv ntsuas xav tau cov kev thaiv hluav taws xob kom tsis txhob cuam tshuam. Piv txwv li, sab hauv siab high - cov khoom siv voltage yog them nrog cov hlab ntsha mesh, thiab cov leeg hluav taws xob yog enccased nyob rau hauv cov hlau plhaub. Ib yam li ntawd, hluav taws xob hloov siv rau tag nrho- yoj lossis ib txheej ntawm cov hlau nplaum qhwv tau muab cov hlau nplaum nyias muaj nyias cov hlau nplaum qhwv tau nruab nrab ntawm thawj thiab ob lub zog kom ua kom tau txais kev tiv thaiv. Nyob rau hauv high - voltage nyob {}} kab ua haujlwm, cov neeg ua haujlwm hnav sib npaug ntawm cov hlau hlau, uas muab rau kev tiv thaiv kev tiv thaiv. Hauv cov tshuab hluav taws xob, ib daim teb hluav taws xob ntsug ntawm kwv yees li 100 v / m muaj nyob ze lub ntiaj teb. Txhawm rau tshem tawm cov nyhuv ntawm daim teb no ntawm cov khoom siv hluav taws xob thiab kawm lawv cov lus tsa suab hauv qab kev plaw ib leeg, ee
