Pulse electromagnetic: fudud in dhismaha

Shabakadda caalamiga ah haatan waxaad ka heli kartaa Xoolo oo ku saabsan waxa ay tahay garaaca wadnaha ah electromagnetic. Dad badan ayaa ka cabsadeen, maxaa yeelay, mararka qaarkood ma ogyahay waxa ku jirta. Shiidaalka in uu dabka ku shub barnaamijyada TV sayniska iyo articles in tabloids ah. Ma fahmin su'aashan, waa wakhti?

Sayidka, garaaca wadnaha ah electromagnetic (EMP) - perturbation a duurka electromagnetic ayaa saamayn on kasta oo wax wax aaga ay tallaabo. Wuxuu saameeyaa walxaha ma aha oo kaliya tabinta, laakiin sidoo kale si insulators, laakiin in nooc ka mid ah wax yar ka duwan. Sida caadiga ah, ereyga "garaaca wadnaha electromagnetic" waa ku xiga si ay ereyga "hub nuclear." Waa maxay sababta? Jawaabtu waa mid fudud: waxa uu ahaa qarax nuclear EMI gaadho qiimaha weyn ee dhan. Malaha, in qaar ka mid ah xarumaha tijaabo ah sidoo kale ma abuuri karaan perturbation xoog leh oo duurka jooga, laakiin waxay yihiin maxalliga ah ee dabiiciga ah, iyo in qarax nuclear saameeyeen aag aad u ballaaran.

Saftay garaaca wadnaha electromagnetic cafinnaa sharciyada dhowr, kaas oo in shaqo maalmeedka wajahay koronto kasta. Sida la og yahay, dhaqdhaqaaqa jiho qayb hoose isagoo lacag koronto, ugu dambaysta la xidhiidha beer magnetic. Haddii ay jirto kaari ah kaas oo qulqulka hadda, ka dibna ku wareegsan waxaa had iyo jeer waxaa lagu diiwaangeliyaa beerta. Taa waxaa ka duwan, gaadhista duurka electromagnetic on wax ka tabinta abuuraa ciidamo electromotive dhexdeeda, oo sidaas awgeed, hadda. Sida caadiga ah sheeg foomamka in kaari wareeg ah, inkasta oo ay tani waa run oo kaliya in ay qayb ka, maxaa yeelay ah hadda Eddy abuuro contours iyaga u gaar ah ee mugga mid ah waxyaabaha tabinta. Qarax nuclear abuuraa dhaqdhaqaaqa ah electrons iyo halkan waxaa duurka. Markaasuu wax walba waa mid fudud: line ee xiisadda, markeeda, abuuro hadda laaluusheen in kirishbooyada ku wareegsan.

hab ay of this ifafaale waa kuwa soo socda: sabab u ah in la sii daayo degdeg ah ee tamarta isagoo socodka walxaha (gamma, Alfa, X-rays , iwm). Inta lagu jiro ay maris iyada oo u taagoo hawada "reebay" electrons, kuwaas oo u janjeedha dhinaca magnetic of dhulka. mooshin A si toos ah (hadda) in abuuraa duurka ah electromagnetic. Oo tan iyo geeddi socodka dhacaan xawaare hillaac, waxaan ka hadli karnaa dardarta. Dheeraad ah, oo dhan kirishbooyada ku jira kala duwan oo duurka (boqollaal kiilomitir) ah, hadda la laaluusheen, oo tan iyo xoog duurka oo waa weyn, qiimaha hadda sidoo kale waa weyn yahay. Tani waxay ku kicin kara nidaamka ilaalinta, fiyuusyada Suurka - ilaa dabkii iyo dhaawac joogta ah. All ficil ah ee shucaaca electromagnetic ka ah wareeggeedii isku dhafan si khadadka gudbinta, in kastoo in heerar kala duwan.

EMI ama gaashaan waa in laga hortago induction oo duurka. Tani waxaa lagu gaari karaa siyaabo dhowr ah:

- in ay u guuraan meel ka fog xuddunta, tan iyo duurka ku jilciyaa la meel fog sii kordhaya;

- baarista (earthed) qalabka korontada,

- "dhigi soo baxay" nidaamka, iyadoo la siinayo ka dhimman in view of hadda weyn.

inta badan waxaad ka heli kartaa su'aasha ah ee sida si ay u abuuraan garaaca wadnaha ah electromagnetic gacmahoodii. Dhab ahaantii, qof kasta oo la soo gudboonaado la on joogta ah maalin walba adigoo gujinaya biiro nalka. Waqtiga bedesheen hadda waa ku meel gaar ah ka badan ee ku magacaaban toban jeer ku wareegsan silig abuuraa duurka ah electromagnetic oo xaadiriyaan in kirishbooyada xeeran ciidanka electromotive. Just xoogga this ifafaale ahi kuma filla in ay keeni dhaawac u dhigma EMP qaraxa nuclear. muujinta More la cadeeyay waxaa ka mid ah waxaa laga heli karaa by qiyaaso heerka duurka u dhow alxanka bedello. Si kastaba ha ahaatee, dhibaatada waa mid fudud: waa in aad diyaarin suurtagalnimada ee dhacdo of qiimaha la degdeg ah oo waaweyn korontada hadda wax ku ool ah.
