Nyob rau hauv tus qauv diode, rau pem hauv ntej biasing tshwm sim thaum qhov hluav taws xob hla ib lub diode tso cai rau lub ntuj ntws ntawm tam sim no, whereas reverse biasing denotes ib voltage hla lub diode nyob rau hauv opposite direction.
Yuav ua li cas rau pem hauv ntej thiab thim rov qab?
A diode (PN junction) nyob rau hauv ib qho hluav taws xob Circuit Court tso cai rau tam sim no ntws yooj yim dua nyob rau hauv ib qho kev taw qhia dua lwm yam. Forward biasing txhais tau tias muab qhov hluav taws xob hla lub diode uas tso cai rau tam sim no ntws tau yooj yim, thaum rov qab biasing txhais tau tias muab qhov hluav taws xob hla lub diode nyob rau sab nraud.
Dab tsi yog qhov txawv ntawm pem hauv ntej thiab thim rov qab?
Kev thim rov qab ua kom lub diode tsis kam, thiab kev tsis ncaj ncees rau pem hauv ntej txo qhov diode tsis kam. Ib qho kev thim rov qab tsis tso cai rau qhov tam sim no ntws, qhov uas nws ntws mus rau hauv kev tsis ncaj ncees rau pem hauv ntej los ntawm diode.
txhais li cas los ntawm kev thim rov qab?
reverse bias Kev siv d.c. qhov hluav taws xob uas tiv thaiv lossis txo qis tam sim no hauv diode, transistor, thiab lwm yam. Piv txwv li, qhov tsis txaus ntseeg tam sim no yuav ntws los ntawm lub diode thaum nws cov cathode ua tau zoo dua li nws cov anode; Tom qab ntawd lub diode tau hais kom rov qab biased. Sib piv rau pem hauv ntej kev tsis ncaj ncees.
Yuav ua li cas rau pem hauv ntej kev tsis ncaj ncees piv txwv?
kev tsis ncaj ncees The d.c. voltage yuav tsum tau tswj xyuas tam sim no ntws nyob rau hauv ib tug bipolar transistor los yog diode los yog txhim khu tam sim no txaus nyob rau hauv lub teb-zoo transistor. Piv txwv li, silicon diode yuav ua tam sim no tsuas yog tias nws cov anode nyob ntawm qhov zoo voltage piv rau nws cov cathode; ces yog hais rau pem hauv ntej biased.

Puas yog pem hauv ntej thiab thim rov qab primers?
Primers yog luv luv ntawm ib leeg DNA uas khij ob qhov kawg ntawm lub hom phiaj sib lawv liag. … Lub rau pem hauv ntej primer txuas mus rau qhov pib codon ntawmqauv DNA (kev tiv thaiv kev hnov lus), thaum qhov rov qab primer txuas rau qhov nres codon ntawm cov hlua txuas ntxiv ntawm DNA (qhov kev nkag siab strand) .
Koj puas yuav tsum nyeem phau bible pem hauv ntej mus rau tom qab?
Cov phau bible yog teem raws li hom phau ntawv thiab tsis yog yuav tsum tau nyeem raws li kev txiav txim. Qhov tseeb, feem ntau cov neeg uas sim nyeem los ntawm npog-rau-npog thiaj li yuav tau daig tom qab ob peb phau ntawv. Zoo mus rau qhov txheej txheem ua ntej thiab rov qab los sau cov ntsiab lus Puas yog qhov zoo tshaj los nyeem phau Vajlugkub thaum pib txog thaum xaus?
Vim li cas peb thim rov qab them nyiaj ua ntej?
Kev thim rov qab tau ua vim xyoo dhau los thiab cov nyiaj them ua ntej yuav raug them lossis siv rau lub xyoo tshiab thiab tsis tas yuav tsum tau sau tseg raws li kev lav phib xaub thiab khoom muaj nqis Cov ntawv nkag yog xaiv tau nyob ntawm seb puas muaj lossis tsis muaj kev hloov kho cov ntawv sau uas yuav tsum tau thim rov qab .
Cov kab mob shingles puas kis rov qab mus rau pem hauv ntej?
shingles ntawm koj lub ntsej muag shingles feem ntau tshwm sim ntawm ib sab ntawm koj sab nraub qaum lossis hauv siab, tab sis koj tuaj yeem ua pob liab liab ntawm ib sab ntawm koj lub ntsej muag. Yog qhov pob pob nyob ze los yog hauv koj pob ntseg, nws tuaj yeem ua rau muaj kab mob uas tuaj yeem ua rau:
Thaum twg cov menyuam yaus rov qab los rau pem hauv ntej?
Thaum twg cov menyuam yaus dov? Koj tus menyuam tuaj yeem ncaws nws tus kheej, ntawm nws lub plab mus rau nws nraub qaum, thaum muaj hnub nyoog 4 hli. Tej zaum nws yuav coj nws mus txog thaum nwskwv yees li 5 lossis 6 lub hlis tig rov qab mus rau pem hauv ntej, tab sis, vim nws xav tau lub caj dab thiab caj npab kom muaj zog rau qhov maneuver.
