Taw qhia txog kev paub txog kev nyob deb ntawm hluav taws xob hluav taws xob
Hauv chav pw
Tsis txhob tso koj lub xov tooj lossis lwm yam khoom siv sib txuas lus rau ntawm lub rooj zaum ntawm txaj, lossis xaiv kom kaw ncaj qha. Hloov chaw, tua lub wireless network ua ntej.Dual Test Functions: EMF meter tuaj yeem kuaj xyuas thiab ntsuas cov hluav taws xob hluav taws xob hluav taws xob thiab hluav taws xob sib nqus emission tib lub sijhawm. Nws kuj tuaj yeem ntsuas qhov kub ntawm ib puag ncig (degree / ℉).
Tsis txhob tso tus menyuam saib ntawm ib sab ntawm lub txaj, muab tso rau qhov deb tsawg kawg 90 centimeters.
Thaum hu
Xaiv los hnav lub mloog pob ntseg lossis siv hom hands-free kom koj lub xov tooj hauv koj lub hnab ris.
Hauv chav nyob
Tsis txhob tso lub thawv Wi-Fi lossis lub xov tooj wireless hauv chav nyob uas koj yuav nyob ntev, thiab sim nyob deb li deb tau.
Hauv chav ua noj
Nruab lub microwave ntawm qhov siab siab tshaj qhov me nyuam, thiab tsis txhob sawv ntsug ntawm lub microwave thaum ua haujlwm. Yog tias koj muaj lwm yam khoom siv hauv chav ua noj uas xav tau hluav taws xob xws li lub lauj kaub kas fes, tshuab ua mov, tshuab ua zaub mov, thiab lwm yam hauv koj chav ua noj, nco ntsoov txiav lub hwj chim thaum tsis siv.
Hauv kev thauj mus los
Tsheb lossis tsheb ciav hlau nyob rau hauv cov lus tsa suab feem ntau tau txais cov cim tsis muaj zog, nyob rau hauv rooj plaub uas cov xov tooj ntawm tes yuav xa cov teeb liab muaj zog dua los sib txuas lus nrog tus kav hlau txais xov ze tshaj plaws. Thov zam kev hu xovtooj lossis xav txog kev siv tes dawb nyob rau lub sijhawm no.
Puas ua haujlwm ntawm lub cev muaj zog tsim hluav taws xob
Qhov dav siv peb-theem lossis ib-theem motors ncaj qha los ntawm 50Hz AC tsis tsim hluav taws xob hluav taws xob vim lawv qhov tsawg zaus thiab du sine yoj.
Tab sis yog tias lub tshuab hluav taws xob pulse width modulation (PWM) siv los tswj lub cev muaj zog, xws li siv lub tshuab hloov pauv zaus los tsav lub cev muaj zog, yuav muaj hluav taws xob hluav taws xob muaj zog hauv cov khoom siv hluav taws xob thiab lub cev muaj zog. Feem ntau vim hais tias cov mem tes tsis muaj cov nplua nuj ntau zaus sib haum xeeb, uas tawm lub zog tawm sab nraud rau hauv daim ntawv ntawm electromagnetic tsis. Cov yoj liab liab uas pom hauv daim duab hauv qab no yog daim duab kab spectral ntawm cov mem tes daj, uas yog muab los ntawm Fast Fourier Transform (FFT) thiab muaj ntau cov khoom siv ntau zaus nrog cov amplitudes siab, tas li radiating zog.
Cov hluav taws xob hluav taws xob tuaj yeem ua rau muaj kev cuam tshuam loj, cuam tshuam nrog kev ua haujlwm ntawm cov khoom siv hluav taws xob nyob ze, thiab txawm tias poob tswj. Kev ntsuas tiv thaiv yuav tsum tau ua kom tshem tawm cov hluav taws xob no, uas yuav luag tsis muaj kev phom sij rau tib neeg lub cev. Ua ntej, nws qhov attenuation yog qhov nrawm, thiab qhov thib ob, nws lub zog tsis tseem ceeb.
