Tsawg tso zis impedance yog xav kom nqus qhov siab tshaj plaws tam sim no los ntawm Circuit Court. High impedance txhais tau hais tias lub voj voog rub lossis muab lub zog me me rau lub teeb liab. Tsawg impedance txhais tau tias lub voj voog rub lossis muab lub zog ntau dua rau lub teeb liab… lub piezo mic yuav xav tau 50k input impedance kom tau ze rau lub microphone impedance.
Dab tsi yog qhov tso zis zoo impedance?
Ib tus kws tshaj lij lossis "zoo" mic tso zis impedance yog nyob rau hauv thaj tsam ntawm 50 Ω - 500 Ω, txawm tias qee cov mics pro muaj impedances me ntsis sab nraum qhov no. Tsuav yog qhov tso zis impedance qis dua (1/10th lossis tsawg dua) tshaj qhov load impedance, nws yog qhov zoo!
Yim impedance txhais li cas?
Tsawg impedance yog nyob rau hauv ntau ntawm kwv yees li 4 txog 16 ohms. Tsawg impedance hais lus yog siv nyob rau hauv ntau lub suab xws li tsev neeg lub tso suab system thiab lub tsheb suab system. Siab impedance feem ntau txhais tau tias impedance ntawm ob peb-pua ohms mus rau ntau-k ohms.
Nws puas zoo rau muaj qhov tso zis siab impedance?
The siab impedance kom ntseeg tau tias nws nqus tam sim no me ntsisNws yog lub tshuab ua haujlwm ua haujlwm los hloov lub zog qis, hluav taws xob-tsav cov teeb liab mus rau qhov siab dua-voltage tso zis teeb liab. Tsawg impedance circuits tuaj yeem ua rau muaj kev phom sij vim tias muaj qhov siab tam sim no uas lawv tsim. Op amps zam qhov no los ntawm kev muaj cov tswv yim impedance siab heev.
Yuav ua li cas yog tias input impedance qis dhau?
Nyob ntawm qhov tsav tsheb thauj khoom, qhov siab dua lossis qis dua input impedance yuav ua rau lub tshuab tsav tsheb nkim ntau lossis tsawg zog sab hauv Lo lus "siab input impedance" yog ib txwm muaj feem xyuam mus rau lub amplifier (suab intermediate zaus fais fab amplifier… thiab lwm yam.)

Dab tsi yog qhov qis qis qis qis?
Under-Frequency Load Shedding (UFLS) yog ib qho txheej txheem los tswj lub zog ruaj khov los ntawm kev tshem tawm cov khoom dhau ntawm qee qhov ntawm lub cev… Lub tswv yim muaj peev xwm txhim kho qhov zaus teb ntawm cov koog pov txwv . Dab tsi yog qhov undervoltage load shedding?
Dab tsi yog qhov tso zis tawm?
Hauv kev suav, kev tawm tswv yim / tawm yog kev sib txuas lus ntawm cov ntaub ntawv ua haujlwm, xws li lub khoos phis tawj, thiab lub ntiaj teb sab nraud, tejzaum nws yog tib neeg lossis lwm cov ntaub ntawv ua haujlwm. Inputs yog cov teeb liab lossis cov ntaub ntawv tau txais los ntawm lub kaw lus thiab cov khoom tawm yog cov teeb liab lossis cov ntaub ntawv xa los ntawm nws.
Puas yog kev tso quav tso zis yog lus kho mob?
Nyob hauv kev saib xyuas kev noj qab haus huv, kev tso quav tso quav yog qhov kev pab tus neeg mob nyob nrog nws cov kev xav tau tshem tawm . hu li cas thaum koj siv chav dej? Kho kom tawm ib lub cev pov tseg. txos tus kheej. tso zis .
Koj puas tuaj yeem siv cov zis tso zis hauv qhov tso zis?
Kev Npaj Ua Qauv Koj tuaj yeem siv cov zis tiag tiag nrog Urinator kit. Muab cov zis tso rau hauv lub syringe. Hloov nws mus rau lub hnab IV, tuav lub ntim ntawm 75ml. Kaw lub hnab nrog lub hau ntswj . lab puas tuaj yeem qhia tau tias nws yog cov zis hluavtaws?
Puas toviaz ua rau tso zis tso zis?
Antimuscarinic Tshuaj Coadministration ntawm Toviaz nrog rau lwm cov tshuaj antimuscarinic tshuaj antimuscarinic cov neeg tseem ceeb muscarinic antagonists muaj xws li atropine, Hyoscyamine, hyoscine butylbromide thiab hydrobromide, ipratropium, tropalicamide, cyclopentopine, thiab cyclopentopine.
