Ncov siab tshaj qhov hluav taws xob ( PIV ) yog qhov siab tshaj plaws qhov muaj peev xwm ua tau thoob plaws a diode thaum nws yog rov qab-biased. Tam sim no voltage hla qhov tsis ua diode D2 yog qhov sib npaug ntawm qhov hluav taws xob hla qis ib nrab ntawm qhov hloov pauv thib ob thiab qhov hluav taws xob hla qhov kev tiv thaiv kev tiv thaiv RL.
Tom qab ntawd, ib tus tseem tuaj yeem nug, PIV ntawm diode hauv Fwr thiab HWR yog dab tsi?
PIV : Cov ncov rov qab qhov hluav taws xob ( PIV ) yog qhov siab tshaj plaws rov qab qhov hluav taws xob diode yuav tsum tiv taus yam tsis tawg. Rectifier (cov FWR ) thiab PIV ntawm diodes yuav tsum tau siv. Cov diode D1 rov qab tsis ncaj thiab ua raws li qhib. Cov diode D2 yog kev ncaj ncees rau pem hauv ntej thiab ua raws li luv luv.
Ib sab saum toj no, PIV ntawm diode hauv ib nrab yoj rectifier yog dab tsi? Cov PIV sawv rau ncov rov qab qhov hluav taws xob hais txog qhov rectifier hluav taws xob tivthaiv. Qhov xwm txheej nthuav tawm qhov txwv qhov hluav taws xob uas tau txiav txim siab rectifier tuaj yeem tiv taus thaum qhov tam sim no hauv rectifier yog rov qab biased. Cov rectifier muaj PN txuas diode uas tso cai rau kev khiav tsis ncaj ntawm qhov tam sim no.
Ntawm no, PIV ntawm diode yog dab tsi?
Peak Rov Qab Voltage ( PIV ) lossis Peak Reverse Voltage (PRV) xa mus rau qhov siab tshaj plaws a diode lossis lwm yam cuab yeej tuaj yeem tiv taus kev thim rov qab-ua ntej kev puas tsuaj. Kuj tseem tuaj yeem raug hu ua Rov Qab Raug Rho Tawm Voltage.
PIV qhov ntsuas ntawm diode hauv choj rectifier yog dab tsi?
Cov ncov inverse voltage PIV yog qhov siab tshaj plaws qhov hluav taws xob rov qab uas tuaj yeem siv thoob plaws diode thiab diode tuaj yeem tiv taus yam tsis ua tiav. Cov ncov inverse voltage PIV rau nruab nrab kais puv nthwv dej rectifier yog 2Vp uas yog qhov siab tshaj ntawm theem nrab ntawm kev hloov pauv.

Dab tsi yog qhov sib txawv ntawm txoj hauv kev sab hauv thiab sab hauv ntawm cov ntshav khov?
Txoj hauv kev hauv tsev xav tau tsuas yog cov khoom sib txuam pom hauv cov ntshav nws tus kheej - tshwj xeeb, cov ntshav khov XII (Hageman factor) los ntawm cov platelets. Txoj hauv kev txuas ntxiv yog pib los ntawm yam sab nraud rau cov ntshav, hauv cov ntaub so ntswg uas nyob ib sab rau cov hlab ntshav puas
Dab tsi yog qhov sib txawv ntawm tunica media hauv cov hlab ntshav piv rau tunica media hauv cov leeg?
Cov hlab ntsha tsis tau ntsib qhov nrawm nrawm uas cov hlab ntsha ua. Yog li ntawd, lawv tsis tas yuav tsum muaj cov txheej txheem muaj zog, thiab lawv tsis yog. Lub nkoj cov phab ntsa ntawm cov hlab ntshav yog nyias dua cov hlab ntsha thiab tsis muaj ntau npaum li tunica media. Cov xov xwm tunica me me cuam tshuam nrog lub lumen ntau dua hauv cov hlab ntsha
Qhov sib piv sib piv rau tus menyuam CPR yog dab tsi?
6.7 Kev Sib Koom Hauv Siab thiab Lub Qhov Ncauj Ib tus neeg cawm siav siv lub tshuab nqus pa-rau-qhov sib piv ntawm 30: 2. Rau 2-cawm tus menyuam mos thiab menyuam CPR, ib tus kws khomob yuav tsum ua lub hauv siab thaum lwm tus ua kom cov hlab pa qhib thiab ua pa tawm ntawm qhov sib piv ntawm 15: 2
PIV hla tus diode yog dab tsi?
Peak Inverse Voltage lossis PIV yog qhov siab tshaj plaws tshwm sim thoob plaws p-n kev sib tshuam diode thaum nws tsis ua. Ib qho diode tsis ua thaum nws rov thim rov qab. Qhov no txhais tau tias qhov siab tshaj qhov hloov pauv qhov hluav taws xob yog qhov siab tshaj qhov hloov pauv tau qhov tsis sib xws hla cov kab hluav taws xob thaum nws muab tso rau hauv Circuit Court
Dab tsi ntawm cov hauv qab no yog ib qho piv txwv ntawm qhov pib kiag?
Nov yog cov piv txwv ntawm qhov pib qhov tseeb rau txhua qhov ntawm tsib qhov kev xav: Lub Zeem Muag - Lub teeb taws tswm ciab 30 mais deb. Hnov - Lub moos ticking 20 feet deb. Smell - Ib qho tshuaj tsw qab hauv ib lub tsev 6 chav
