Kev nyab xeeb deb ntawm electromagnetic hluav taws xob
Cov kws tshaj lij hais tias txhua yam khoom siv hluav taws xob tuaj yeem tsim hluav taws xob hluav taws xob ntev li ntev tau siv tam sim no, xws li cov tshuab cua txias, TV, khoos phis tawj, microwaves, humidifiers, mus rau lub tshuab ziab khaub ncaws, xov tooj ntawm tes, chargers, thiab txawm tias cov hlua txuas. Txawm li cas los xij, tus nqi hluav taws xob tsim los ntawm ntau yam khoom siv sib txawv.
Tom qab tshawb xyuas cov qib hluav taws xob tshwj xeeb, tus neeg sau xov xwm tsis pom ib qho qauv txheej txheem rau cov hluav taws xob hluav taws xob sib txawv hauv Suav teb. Txawm li cas los xij, SAPIO magazine luam tawm hauv Nyij Pooj tau tshaj tawm cov ntaub ntawv tshawb xyuas hluav taws xob hluav taws xob hluav taws xob rau cov khoom siv hauv tsev (saib cov lus).
Txawm hais tias hluav taws xob nyob txhua qhov chaw, Zhao Yufeng, tus thawj coj ntawm Pawg Kws Tshaj Lij ntawm Tuam Tshoj Sab Hauv Tsev Saib Xyuas Ib puag ncig, tau taw qhia tias tsis yog txhua qhov hluav taws xob hluav taws xob tuaj yeem ua mob rau tib neeg lub cev. Yog hais tias qhov sib nqus teb siv tau tswj nyob rau hauv qhov kev teev tseg, nws muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo rau tib neeg lub cev. Piv txwv li, lub tshuab kho lub cev uas muag hauv khw siv cov nyhuv sov ntawm hluav taws xob hluav taws xob kom tshem tawm qhov mob thiab kho cov kab mob. Yog li ntawd, qhov teeb meem tseem ceeb yog tswj cov hluav taws xob hluav taws xob hauv qhov chaw nyab xeeb.
Yog tias cov neeg siv khoom xav paub txog qib hluav taws xob hauv lawv ib puag ncig, lawv tuaj yeem siv txoj kev ntsuas ntsuas. Tab sis tam sim no, domestically tsim testers nqi ntawm ob peb puas yuan tej zaum yuav muaj deviations nyob rau hauv kev ntsuas cov ntaub ntawv, thaum ib co txawv teb chaws testers raug nqi ntau pua txhiab yuan, uas yog nyuaj rau cov neeg zoo tib yam lees txais.
Zhao Yufeng tau hais tias txoj kev saib xyuas yooj yim tuaj yeem siv los pab tib neeg kom nkag siab txog kev nyab xeeb ntawm cov khoom siv hluav taws xob: siv lub xov tooj cua uas tuaj yeem tau txais AM (amplitude modulation) raws, tig lub channel thiab kho nws mus rau qhov chaw tsis muaj kev tshaj tawm, thiab mus txog. cov khoom siv hauv tsev xws li TV, tub yees, microwave, lossis khoos phis tawj los ntsuas, lub suab nrov ntawm lub xov tooj cua yuav dheev nce. Tom qab taug kev ib qho deb, qhov qub me suab nrov yuav raug rov qab los; Nyob rau hauv txoj kev no, qhov kev nyab xeeb nyob deb tuaj yeem ntsuas tau, thiab nws txaus los tswj qhov ntsuas kev nyab xeeb ntawm cov khoom siv no hauv lub neej txhua hnub.
