A PFC xeem xam cov tam sim no uas yuav ntws nyob rau hauv qhov xwm txheej ntawm lub ntiaj teb txhaum; i.e. Line to Earth. Nws yog ib qho tseem ceeb uas peb ua tus kev xeem kom paub tseeb tias cov cuab yeej tiv thaiv uas tau teeb tsa hauv kab hluav taws xob tau ntsuas ntawm qhov muaj peev xwm tawg tau raug.
Thiaj li, PFC yog dab tsi hauv hluav taws xob?
Yav tom ntej luv luv Circuit Court (PSC) thiab Prospective Fault Current ( PFC ) yog ob qho tib si tsim los txhawm rau suav qhov siab tshaj tam sim no uas yuav ntws hauv txoj kab kev ua txhaum thaum lub sijhawm tshwm sim hluav taws xob txhaum raws li kev cai.
Tom qab ntawd, lo lus nug yog, koj yuav kuaj IPF li cas? Txoj kev zoo tshaj plaws rau koj tus kws kho mob kom kuaj tau IPF yog coj cov qauv me me ntawm cov ntaub so ntswg los ntawm koj lub ntsws thiab kuaj lawv nyob hauv lub tshuab tsom me me kom pom tias muaj caws pliav lossis lwm yam kab mob.
Ntawm no, dab tsi yog qhov siab tshaj yav tom ntej txhaum tam sim no?
Cov siab tshaj plaws yav tom ntej txhaum tam sim no yog qhov siab tshaj ntawm ob txhaum tam sim no (kab-rau-nruab nrab lossis kab-rau-lub ntiaj teb) thiab yuav tsum tau sau rau ntawm daim ntawv pov thawj lossis daim ntawv tshaj tawm, uas yog ib feem ntawm cov ntsiab lus ntawm cov khoom siv.
PFC test yog dab tsi?
A PFC xeem xam cov tam sim no uas yuav ntws nyob rau hauv qhov xwm txheej ntawm lub ntiaj teb txhaum; i.e. Line to Earth. Nws yog ib qho tseem ceeb uas peb ua tus kev xeem kom paub tseeb tias cov cuab yeej tiv thaiv uas tau teeb tsa hauv kab hluav taws xob tau ntsuas ntawm qhov muaj peev xwm tawg tau raug.

Lub hom phiaj ntawm cov roj raus dej uas siv nrog 100x lub hom phiaj xeem ntawv yog dab tsi?
Hauv lub tshuab tsom me me, kev tso roj yog txheej txheem siv txhawm rau txhawm rau daws qhov teeb meem ntawm lub tsom iav. Qhov no yog ua tiav los ntawm kev raus ob lub hom phiaj tsom iav thiab cov hnoos qeev hauv cov roj pob tshab ntawm qhov ntsuas siab refractive, yog li ua kom cov zauv zauv ntawm lub hom phiaj tsom iav
Lub hom phiaj ntawm kev xeem lactose fermentation yog dab tsi?
Lactose Fermentation Test. Lub hom phiaj yog saib seb lub microbe tuaj yeem zom cov carbohydrates (piam thaj) lactose ua cov pa roj carbon. Yuav ua li cas txiav txim siab lactose fermentation? Yog tias lactose tau fermented los tsim cov khoom ua kua qaub, pH ntawm nruab nrab yuav poob
Lub hom phiaj ntawm kev xeem OAE yog dab tsi?
Koj lub pob ntseg tau tsim los ntawm peb ntu - sab nraud, nruab nrab, thiab pob ntseg sab hauv. Kev kuaj OAE yog siv los xyuas seb koj lub pob ntseg sab hauv, lossis cochlea, ua haujlwm zoo npaum li cas. Nws ntsuas otoacoustic emissions, lossis OAEs. Lub suab no yog OAE uas ntsuas. Yog tias koj hnov lus tsis zoo, koj yuav tsim OAEs
Lub hom phiaj ntawm kev xeem CDP yog dab tsi?
Computerized dynamic posturography (CDP) kev ntsuam xyuas yog ib qho txheej txheem siv los ntsuas qhov kev hnov qab thiab kev tswj lub cev muaj zog cuam tshuam nrog kev sib npaug. Nws tsis paub qhov chaw ntawm pathology, tab sis theej sau cov kev puas tsuaj uas yog kev ua haujlwm ntawm cov kab mob pathology
Lub hom phiaj ntawm kev xeem ib ntsiav tshuaj yog dab tsi?
Cov ntsiav tshuaj cov qhab nia yog hais txog kev tawg ntawm cov ntsiav tshuaj kom tau txais cov koob tshuaj uas xav tau thiab yog lub tswv yim tshwm sim hauv kev lag luam tshuaj. Qhov laj thawj tseem ceeb rau kev ntsuas ntsuas cov ntsiav tshuaj yog txhawm rau kho qhov koob tshuaj: txhaj tshuaj kom haum lossis txhaj tshuaj
