Lub quarter - yoj (λ/4- yoj ) coaxial resonators yog tsim los ntawm shorting lub nruab nrab neeg xyuas pib ntawm ib tug coaxial cable mus rau daim ntaub thaiv npog nyob deb kawg ntawm lub Circuit Court. Qhov ntev ntawm lub cable yog raws nraim λ / 4 ntawm qhov xav tau resonant zaus. Nws ua haujlwm zoo li qhov sib npaug ntawm L / C tank Circuit Court.

Ib yam li ntawd, nws raug nug, lub quarter wavelength txhais li cas?

Nws yog qhov ntawd lub quarter wavelength txoj cai muaj qhov chaw txaus kom nqus tau tsawg kawg 25% ntawm tus qauv tsim peb tab tom mus tom qab nqus. Yog tias peb siv 40 Hz. tus wavelength ntawm 28' nyob rau hauv tag nrho ntev thiab faib tus lej ntawd los ntawm 4, peb tau txais a lub quarter wavelength ib ncig ntawm 7'.

Tom qab, lo lus nug yog, dab tsi yog kev siv kab noj hniav resonator? Lub kab noj hniav resonator yog ib qho uas nthwv dej muaj nyob hauv qhov chaw hollow hauv lub cuab yeej. Hauv electronics thiab xov tooj cua, microwave kab noj hniav uas muaj hollow hlau thawv yog siv nyob rau hauv microwave transmitters, receivers thiab cov cuab yeej kuaj xyuas kom tswj tau qhov zaus, nyob rau hauv qhov chaw ntawm cov kab hluav taws xob tuned uas siv nyob rau hauv qis zaus.

Hauv qhov no, dab tsi yog txhais los ntawm kab noj hniav resonator?

Txhais ntawm kab noj hniav resonator .: ib qho khoom siv hluav taws xob uas muaj qhov chaw feem ntau nyob nrog cov phab ntsa hlau nyob rau hauv uas suab nrov electromagnetic teb tej zaum yuav zoo siab thiab muab rho tawm siv nyob rau hauv microwave systems.

Lub nplhaib resonator hauv microwave yog dab tsi?

Lub ntug txuas nrog microstrip nplhaib resonator feem ntau yog siv los txiav txim microwave substrate zog, tshwj xeeb tshaj yog dielectric tas li thiab poob tangent. Nws kuj tseem paub zoo tias nyob rau hauv qee qhov xwm txheej, microstrip nplhaib Circuit Court tuaj yeem ua raws li tus kav hlau txais xov nqaim.

Lub quarter kawg ntawm lub hli nce lub sijhawm twg?

Cov theem ntawm lub hli theem nce, kev hloov mus thiab teem sij hawm daim duab qhia txoj hauj lwm Tag Nrho Lub hli nce thaum hnub poob, hla meridian thaum ib tag hmo, teem rau hnub sawv E Waning Gibbous sawv tom qab hnub poob, hla ib tag hmo, teev tom qab hnub sawv F Lub Peb Hlis Ntuj nce thaum ib tag hmo, kev mus los. meridian ntawm lub hnub tuaj, teev thaum tav su G

Dab tsi yog kev sib raug zoo ntawm wavelength zaus thiab qhov ceev ntawm lub teeb?

Lub wavelength thiab zaus ntawm lub teeb yog ze ze. Qhov siab dua qhov zaus, qhov luv dua lub wavelength. Vim tias txhua lub teeb tsis txav mus los ntawm lub tshuab nqus tsev ntawm tib lub nrawm, tus naj npawb ntawm nthwv dej crests dhau los ntawm ib qho taw tes hauv ib thib ob nyob ntawm qhov wavelength

Lub wavelength ntawm mercury yog dab tsi?

Tsuas yog lub teeb ntawm 253 nm tuaj yeem siv tau. Fused silica yog siv nyob rau hauv kev tsim khoom kom 184 nm lub teeb los ntawm absorbed. Nyob rau hauv nruab nrab-siab mercury-vapor teeb, cov kab ntawm 200-600 nm yog tam sim no. Emission kab spectrum. Wavelength (nm) Lub Npe (saib photoresist) Xim 435.8 G-kab xiav 546.1 ntsuab 578.2 daj-txiv kab ntxwv

Dab tsi yog qhov txawv ntawm wavelength ntawm lub teeb liab thiab lub teeb violet?

Violet lub teeb yog hluav taws xob hluav taws xob hluav taws xob nrog wavelengths ntawm 410 nanometers thiab lub teeb liab muaj awavelength ntawm 680 nanometers. Qhov ntau ntawm wavelengths (400 - 700 nm) ntawm lub teeb pom kev yog nyob nruab nrab ntawm lub electromagnetic spectrum (Fig.1)
