Ring Circuit Test ib ntus:
- Nyob rau hauv lub rooj tsavxwm, tshem tawm cov kab, nruab nrab thiab lub ntiaj teb conductors ntawm nws cov terminals.
- Ntsuas ntawm Kab rau Kab kom tau txais kev nyeem ntawv rau " r1 qib ”
- Ntsuas nruab nrab ntawm nruab nrab mus rau nruab nrab kom tau txais kev nyeem ntawv rau "rn"
- Ntsuas nruab nrab ntawm Lub Ntiaj Teb thiab Lub Ntiaj Teb kom tau txais kev nyeem ntawv rau " r2 qib ”
Ib yam li ntawd, nws tau nug, koj ua li cas xam r1 r2 los ntawm Zs?
Txoj kev los txiav txim Zs
- Kev ntsuas ncaj qha ntawm Zs siv lub ntiaj teb txhaum lub voj impedance ntsuas ntsuas.
- Ntxiv qhov tshwm sim ntawm tus nqi ntawm lub ntiaj teb sab nraud txhaum lub voj impedance (Ze) rau qhov ntsuas tus nqi ntawm (R1 + R2) ntawm qhov kawg ntawm lub voj voog.
- Kev ntsuas ntawm Ze.
- Kev ntsuas (R1 + R2)
Tom qab ntawd, lo lus nug yog, vim li cas koj faib r1 r2 los ntawm 4? Vim hais tias ib qho RFC yog qhov tseeb ob lub conductors nyob rau hauv parallel, qhov tsis kam yog halved lwm 1/2. Muab ob qho no 1/2s ua ke thiab koj tau 1/ 4 . Yog li ntawd thaum peb ntsuas r1 qib + r2 qib hauv RFC, peb faib los ntawm 4 kom tau R1 + R2.
Tom qab ntawd, ua li cas koj xam Zs ntawm lub nplhaib tseem ceeb?
Yuav nrhiav tau zs ntawm a nplhaib Circuit Court koj yuav tsum hla txuas ntawm lub hauv paus chiv keeb nplhaib , piv txwv li, txuas cov theem nkag mus rau qhov tawm mus cpc thiab vice-versa, ces ntsuas nruab nrab ntawm theem & cpc ntawm tag nrho cov qhov (socket), qhov kev nyeem ntawv siab tshaj plaws muab r1 + r2 daim duab, tsuas yog ntxiv qhov no rau koj daim duab ze thiab koj nyob ntawd!
Vim li cas peb thiaj ua r1 r2 xeem?
Rau txhua qhov hluav taws xob ntawm lub voj voog, qhov kev tawm tsam ntawm ob qho tib si nyob thiab lub ntiaj teb conductors ua ke ( R1 + R2 ) yog ntsuas rov qab mus rau qhov chaw. Qhov no xeem kuj tseem pab txheeb xyuas cov teeb meem polarity - piv txwv li, yog tias cov xaim nyob tau raug hloov pauv nrog cov xaim nruab nrab ntawm qhov chaw hauv ib lub voj voog.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
Lub luag haujlwm tseem ceeb ntawm lub teeb pom kev ntawm photosynthesis yog dab tsi?
Lub luag haujlwm tag nrho ntawm cov tshuaj tiv thaiv lub teeb, thawj theem ntawm photosynthesis, yog hloov lub hnub ci zog rau hauv cov tshuaj siv hluav taws xob nyob rau hauv daim ntawv ntawm NADPH thiab ATP, uas yog siv nyob rau hauv lub teeb-yooj yim tshuaj tiv thaiv thiab roj sib sau ua ke ntawm qab zib molecules
