Cov daws teeb meem ntawm lub hom phiaj tsom iav yog ntsuas los ntawm nws lub peev xwm los sib txawv ob kab lossis cov ntsiab lus hauv ib yam khoom. Qhov loj dua daws teeb meem , qhov tsawg dua qhov kev ncua deb ntawm ob kab lossis cov ntsiab lus uas tseem tuaj yeem sib txawv. Qhov loj dua NA, qhov siab dua cov daws teeb meem.
Ces, koj txhais li cas los ntawm kev daws hwj chim?
Kev daws lub zog txhais tau tias yog lub peev xwm ntawm lub tshuab tsom iav lossis lub tsom iav kom paub qhov txawv ntawm ob qhov sib ze ua ke raws li kev sib cais. Piv txwv ntawm daws teeb meem yog qhov zoo npaum li cas lub telescope tuaj yeem pom ob lub hnub qub raws li cov hnub qub cais. Koj phau ntawv txhais lus txhais thiab siv piv txwv.
Tsis tas li, lub zog daws teeb meem ntawm tib neeg qhov muag yog dab tsi? Cov daws lub zog ntawm tib neeg lub qhov muag yog 200 micrometers piv rau 0.2 rau lub tshuab tsom me me sib xyaw.
Xav txog qhov no, koj xam xam daws teeb meem li cas?
Kev daws teeb meem (Nplooj 2)
- λ = wavelength
- u = lub kaum sab xis ntawm lub khob hliav qab los ntawm qhov khoom.
- u '= lub kaum sab xis ntawm lub khob ntawm lub teeb tsim duab.
- n = refraction index ntawm kwv.
- m = loj.
- NA = tus lej zauv.
- d = nrug nruab nrab ntawm ob lub ntsiab lus hauv daim duab. d = 0.61 λ / (m tanu') (1) * **
Qhov tseem ceeb ntawm kev daws lub hwj chim yog dab tsi?
Cov daws lub zog ntawm lub tshuab tsom iav feem ntau tseem ceeb feature ntawm optical system thiab influences lub peev xwm los paub qhov txawv ntawm cov ntsiab lus zoo ntawm ib qho qauv.

Lub zog daws teeb meem ntawm lub teeb tsom yog dab tsi?
Daws Teeb Meem. Lub zog daws teeb meem ntawm lub hom phiaj tsom iav yog ntsuas los ntawm nws lub peev xwm los sib txawv ob kab lossis cov ntsiab lus hauv ib qho khoom. Lub zog daws teeb meem ntau dua, qhov me me qhov deb tsawg kawg ntawm ob kab lossis cov ntsiab lus uas tseem tuaj yeem ua qhov txawv
Puas tuaj yeem daws qhov kev daws teeb meem?
Nrog rau lwm cov zis tso zis, koj yuav tsum txhawj xeeb txog microwaving nws thiab ua kom nws nyob ze rau koj lub cev kom tsis txhob poob cua sov. Sub Kev daws teeb meem, txawm li cas los xij, muaj daim ntawv tso cai ua kom sov - lub vial me me ntawm lithium chloride (LiCl) uas tsis tuaj yeem kuaj pom los ntawm kev tshuaj yeeb tshuaj. Cov cua kub ntau dhau tuaj yeem tsim nyog pov tseg
Dab tsi yog qhov sib txawv tseem ceeb ntawm teeb meem tsom mus rau kev daws teeb meem thiab kev xav tsom mus rau kev daws?
Thaum kev ntxhov siab pom tau tias yog tswj tau, teeb meem tsom mus rau cov tswv yim daws teeb meem cuam tshuam nrog cov tsos mob ntawm kev puas siab puas ntsws, thaum nyob hauv qhov xwm txheej tsis txaus ntseeg, kev xav-tsom mus rau kev daws teeb meem cuam tshuam nrog cov tsos mob tsawg dua
Puas yog kev daws teeb meem kev kho mob tib yam li kev daws teeb meem luv luv kho?
Kev kho mob tsom mus rau kev kho mob, tseem hu ua kev daws teeb meem hais qhia luv (SFBT), yog hom kev kho mob uas muab qhov tseem ceeb tshaj ntawm kev tham txog kev daws teeb meem ntau dua (Berg, nd) Lo lus "luv luv" hauv kev kho mob luv luv yog qhov tseem ceeb
Dab tsi yog qhov txawv ntawm grey teeb meem thiab cov teeb meem dawb?
CNS muaj ob hom ntaub so ntswg: grey teeb meem thiab dawb teeb meem, Grey teeb meem, uas muaj ib tug pinkish-grey xim nyob rau hauv lub hlwb nyob, muaj cov cell lub cev, dendrites thiab axon terminals ntawm neurons, yog li nws yog qhov twg tag nrho cov synapses. Qhov teeb meem dawb yog ua los ntawm axons txuas sib txawv ntawm qhov teeb meem grey rau ib leeg
