Mus kuaj av resistivity, txuas lub hauv av tester raws li qhia hauv daim duab 1. Plaub av av cov ceg txheem ntseeg yog positioned nyob rau hauv av nyob rau hauv ib txoj kab ncaj nraim, equidistant ntawm ib leeg. Qhov kev ncua deb ntawm av av cov ceg txheem ntseeg yuav tsum yog tsawg kawg peb zaug ntau dua li qhov tob ntawm ceg txheem ntseeg.
Tib neeg kuj nug, koj ntsuas av tiv thaiv li cas nrog lub multimeter?
2 Teb. Txoj kev yooj yim, tab sis me ntsis kev ntseeg tsis tau siv cov hlau ntev thiab a DMM . Txuas ib kawg ntawm cov hlau mus rau qhov paub, zoo ntiaj teb tiv tauj (tej zaum ib sab ntawm qhov chaw uas koj lub thawv fuse raug teeb tsa). Ntsuas tus tsis kam los ntawm lwm qhov kawg ntawm kab mus rau qhov hauv av connector ntawm qhov hluav taws xob / khoom siv los kuaj.
Qhov thib ob, koj ua li cas kuaj lub hauv av? Muaj ob (2) txoj hauv kev rau kuaj ib qho hluav taws xob grounding system . Thawj yog 3-point lossis Fall-of- Potential method thiab qhov thib ob yog Induced Frequency xeem los yog txoj kev clamp-on. Qhov 3-point xeem yuav tsum tau ua kom tiav kev cais tawm ntawm lub hwj chim hluav taws xob.
Tsis tas li ntawd, pes tsawg ohms yog av zoo?
5ohm ua
Kev nyeem ntawv ntawm 0 ohms txhais li cas?
Kuj ntsuas nyob rau hauv ohms ua nrog tsis muaj tam sim no ntws los ntawm Circuit Court. Nws qhia tias xoom ohms ua thaum tsis muaj kev tawm tsam ntawm cov ntsiab lus xeem. Qhov no qhia tau hais tias kev txuas ntxiv ntawm cov dej ntws tam sim no hauv lub kaw lus kaw. Nws qhia tias infinity thaum tsis muaj kev sib txuas hauv Circuit Court uas zoo li nyob rau hauv ib qho qhib Circuit Court.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Puas yog dej tiv thaiv tsis muaj zog tiv thaiv?
Kev sib txhuam yog lub zog tshwm sim los ntawm ob yam khoom sib tsoo ua ke. Huab cua tsis kam thiab dej tsis kam yog hom kev sib txhuam. Lawv hu ua non- contact rog
Koj ntsuas tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed li cas?
Enzyme catalysis yog kuaj pom los ntawm kev ntsuas qhov pom ntawm cov khoom lossis ploj ntawm cov reactants. Txhawm rau ntsuas qee yam, koj yuav tsum muaj peev xwm pom nws. Enzyme assay yog cov kev ntsuam xyuas tsim los ntsuas kev ua haujlwm ntawm enzyme los ntawm kev ntsuas qhov kev hloov pauv hauv cov ntsiab lus ntawm cov tshuaj uas pom tau
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
