Dab tsi yog qhov cuam tshuam ntawm shielding thawv?

Shielding effect:
A: Nws yog txwv tsis pub cov hluav taws xob hluav taws xob hluav taws xob hauv cov khoom siv dhau ntawm ib cheeb tsam, uas yog, kom nqus cov teeb liab cuam tshuam sab hauv;
B: Nws yog los tiv thaiv sab nraud hluav taws xob hluav taws xob hluav taws xob los ntawm kev nkag mus rau qee qhov chaw, uas yog, tiv thaiv cov teeb meem sab nraud cuam tshuam
Shielding tswvyim: Thaum lub simulated cuam tshuam qhov chaw muab tso rau sab nraum lub shielding lub thawv, qhov piv ntawm cov hluav taws xob teb siv, magnetic teb siv los yog lub zog ntawm ib tug tej yam taw tes nyob rau hauv qhov chaw ua ntej thiab tom qab lub shielding lub thawv yog muab tso rau ces logarithmically (lgp1/p2. ), qhia hauv dB.
C: Cov khoom siv kuaj: network analyzer, teeb liab generator, spectrum analyzer, dipole kav hlau txais xov, horn antenna, shielding box.
