Ib AC hloov feem ntau pheej yig "microgap" kev tsim kho. Thaum twg hloov OFF, qhov sib txawv ntawm kev sib cuag tuaj yeem me me. Piv txwv li, a DC hloov tuaj yeem tswj tau qhov arc rau lub sijhawm ntev, raws li qhov voltage hla lub hloov yuav nce mus rau cov khoom siv hluav taws xob thiab nyob twj ywm kom ntev li ntev tau cov khoom siv txuas nrog.
Ib yam li ntawd, nws tau nug, puas AC keyboards ua haujlwm nrog DC?
AC yog nws tus kheej-extinguishing txij thaum tam sim no mus rau xoom 120 zaug txhua ob. DC ua tsis yog li ntawd hloov yuav tsum ciaj sia kom txog thaum lub arc tuag rau nws tus kheej. Yog li cov DC hloov yuav tsum harder thiab yuav yog li ntawd ua haujlwm nrog AC . Txawm li cas los xij, lub AC hloov tsis yog hardy thiab yuav tsum tsis txhob siv nrog DC.
Qhov thib ob, yog lub teeb hloov AC lossis DC? AC thiab DC Hloov A DC hloov siv lub pulsating tam sim no uas tsis tau thim rov qab lub ntsiab lus nws yog tas li nyob rau hauv cov kev taw qhia nws ntws whereas raws li ib tug AC hloov siv ib tug tam sim no uas thim rov qab nws tus kheej nyob rau hauv kev taw qhia thaum lub sij hawm ua hauj lwm kom tso cai rau ib tug ntau txawm pulsation tam sim no.
Ua kom pom qhov no, DC hloov pauv yog dab tsi?
Xav txog tias koj muaj ob lub voj voog, txhua tus nqa tib lub sijhawm tam sim no-ib qho yog AC Circuit Court thiab lwm qhov yog a dc ua Circuit Court. Thaum koj hloov tawm lub hwj chim mus rau ib qho hluav taws xob ac, ib qho hluav taws xob hluav taws xob (los yog arc) yog tsim nyob rau hauv hloov uas yog ceev ceev extinguished-ib yam kev ntshaw.
AC thiab DC Circuit Court yog dab tsi?
Direct tam sim no ( DC ) yog qhov ntws ntawm cov nqi hluav taws xob hauv ib qho kev taw qhia nkaus xwb. Hloov tam sim no ( AC ) yog qhov ntws ntawm cov nqi hluav taws xob uas ncua sij hawm thim rov qab. Yog hais tias qhov chaw sib txawv raws sij hawm, tshwj xeeb tshaj yog sinusoidally, lub Circuit Court yog lub npe hu ua ib alternating tam sim no Circuit Court.

Kev hloov pauv, hauv molecular biology, yog hais txog kev hloov pauv hauv deoxyribonucleic acid (DNA), qhov twg ib qho (ob lub nplhaib) purine hloov pauv rau (ib lub nplhaib) pyrimidine, los yog vice versa
Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Dab tsi tsim cov roj siab thiab nws hloov pauv li cas nrog kev hloov pauv hauv kinetic zog?
Gas siab yog tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv roj nrog rau sab hauv ntawm lub thawv thaum lawv sib tsoo nrog thiab tawm dag zog rau ntawm phab ntsa ntim. Tom qab ntawd cov roj yog cua sov. Raws li qhov kub ntawm cov roj nce, cov khoom tau nce lub zog kinetic thiab lawv cov nrawm nrawm
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Peb qhov laj thawj tseem ceeb ntawm kev hloov pauv hloov pauv yog dab tsi?
Allele frequencies nyob rau hauv ib tug pej xeem yuav hloov vim plaub lub hauv paus zog ntawm evolution: Natural Selection, Genetic Drift, Mutations thiab Gene Flow. Kev hloov pauv yog qhov kawg ntawm cov alleles tshiab hauv cov noob caj noob ces. Ob ntawm cov txheej txheem tseem ceeb tshaj plaws ntawm kev hloov pauv hloov pauv yog: Natural Selection thiab Genetic Drift
