Isibane ezilawulwa ngekhompyutha: diode kunye triode

Makhe sithethe kwemithambo kulawulwa ngekhompyutha.

Yintoni na ke izibane ezilawulwa ngekhompyutha?

isibane Amaphepha-elawulwa - na izixhobo zombane kunye nenani elithile electrode ukuba umsinga wombane kuphela kwelinye icala. Ukususela inani electrode ixhomekeke igama isibane: diode (electrode ezimbini), i triode (electrode amathathu), pentode (electrode ezintlanu), njalo njalo zisetyenziswa Electrical Engineering, elektroniki, amandla kunye namanye amashishini ezininzi ube ukulungisa i alternating current yombane .. kwakunye kuchaphazela nezihlandlo lwangoku, ungenelela kakutsha kwaye switsha izangqa ngamandla. Wena andazi kutheni kukho diode kunye triode? Qhubeka ukuze kulungiswe lo msantsa.

diode

A diode yinto isibane elilawulwa ngekhompyutha apho kukho electrode ezimbini. Ama kunye transistors wecandelo elijongene zekhompyutha ezahlukeneyo linani electrode, khumbula oku. Ngokusekelwe nemigaqo emzimbeni, ukuphunyezwa nokusebenza kwabo zohlulwa ngokwendidi ezinjalo (ngokulandelelana, iintlobo nganye yahlulwe kwinani sub-species):

1. vacuum Electric. Esetyenziselwa ukulungisa. Xa itshiswe kwiqondo lobushushu wacela cathode (xa kukho amadlozi thermoelectric) kondliwa ngawo anode kuthelekiswa le ombane cathode yi-HIV. Emva koko yinxalenye elektroni bakhululekileyo ijoliswe kwabo anode, kwaye diode yangoku abembumbile. Ukuba oku akwenzeki, ngoko ke electron ubuyele cathode.

2. Ikhulule. Isebenziselwa yokukhulisa amandla enkulu kunye nokuzinziswa ntshikilelo ezinkulu. Bamele cathode kunye anode ibekwa yegesi okanye irhasi umxube egalelwe phantsi koxinzelelo ethile.

3. Semiconductor. izicelo anokwenzeka zahlukahlukene kakhulu. Ingaba izixhobo apho inguqu yombane kuyalungiswa kwaye kukho output ezimbini lwangaphandle. Njengoko ekulungiseni utshintsho lombane a isiphambuka PN, umfowunelwa semiconductor-metal okanye giperperehoda.

triode

diode Ngokungafani, triode, ngaphandle anode kunye cathode, kwaye ulawulo ngakumbi electrode, ekuthiwa grid. Ifunyanwa phakathi anode kunye cathode ukulawula grid ivumela isibane electron flow ngokuguqula ubungakanani kunye wokwephuka le ombane phakathi kwigridi ze cathode. Kungenxa yale ikhono kuthiwa ulawulo grid.

Net, kwiimeko ezininzi, i kweleli ye wire ezingcakacileyo esijikeleze cathode. Khupha kwi-nickel, molybdenum, aluminium zabo, yaye tantalum, kunye Tungsten. I esezantsi amandla yegridi, umsebenzi ngaphezulu ukwenza electron ndiye entsimini. Phantsi amaxabiso athile elibi ombane, akukho electron akayi kuba nako ukuyeka intsimi kwigridi, kwaye anode yangoku transistor iya kuba zero. Triols adla ngokusetyenziswa ukuba kunyuswe umqondiso xa efumana imiqadi eriyali.

ukusetyenziswa okusebenzayo

Le transistor kunye diode, nokwakheka yokusebenzisa ukhanyise inyathelo esemgangathweni phambili uphuhliso yonke into enxulumene kunye nombane. Kunzima ukucinga ngaphandle iradio, iTV, iikhompyutha, iifowuni, kunye nezinye izinto ezininzi. Ama kunye transistors kusetyenziselwa kuphela kwimveliso ngomlinganiselo omkhulu, kodwa amateurs koonomathotholo kunye elektroniki kanomathotholo imifuniselo zabo ekhaya. Kunzima ukuba nomfanekiso-bhodi advanced yesekethe eziprintiweyo, nto leyo eza kulawula iteknoloji entsonkothileyo, yaye apho kuya kubakho izibane ezilawulwa ngekhompyutha. Ama kunye transistors kufuneka uluhlu olubanzi kakhulu lezicelo, ngoko ubukho eziliqela ezi isixhobo engasetyenziswayo nakweyiphi kunomathotholo ham cishe alunakuqinisekiswa. Kodwa izicelo zazo zepraktikhali kufuneka silumke - oko zombane, asebenza kunye ombane, nokuba incinane, kodwa imiphumo iya kuba krakra ubuncinane ngoyaba imithetho yokhuseleko.
