Txawm hais tias txhua qhov kev ua tiav thiab kev tshawb pom uas cov kws tshawb fawb tuaj yeem khav tau, tseem muaj ntau yam tsis paub daws teeb meem hauv lub ntiaj teb niaj hnub no. Yog li, niaj hnub no, kev tshawb fawb hauv thaj chaw ntawm tib neeg kev ua haujlwm xws li biology, tshuaj, archaeology, botany, thiab kev tshawb fawb txog kev puas hlwb tsis nres.

Hauv kev tshawb fawb, cov khoom ntawm cov tshuab kho qhov muag yog qhov tseem ceeb, uas suav nrog lub tsom iav thiab lub lens. Nws yog hais txog lawv uas yuav tham txog hauv kab lus no. Peb yuav txiav txim siab nws yog dab tsi, qhov sib txawv ntawm cov khoom thiab qhov twg yog qhov zoo dua los muab qhov nyiam rau.

Sib piv cov yam ntxwv

Ua ntej koj pib sib piv lub tsom iav thiab lub lens, nws yuav muaj qhov nkag siab tias txhua yam ntawm cov khoom saum toj no yog dab tsi.

Lub tsom iav yog ib qho cuab yeej kho qhov muag … Nws lub ntsiab tseem ceeb yog lub lens: ib lossis ob peb. Lub tshuab tsom iav tau siv hauv ntau yam kev lag luam txhawm rau ua kom pom thiab saib cov khoom me me.

Nws yog lub luag haujlwm thiab thawj qhov tseem ceeb tshaj plaws thaum ua kev tshawb fawb.

Cov txheej txheem tseem ceeb ntawm cov tsom iav yog:

• focal ntev;
• fais fab kho qhov muag;
• qhov loj tshaj thaum pom ze thiab deb;
• qhov loj tshaj rau kev siv rov qab;
• qhov tseeb ntawm kev luam xim.

Muaj ntau hom loupes, txhua tus uas tau siv hauv kev lag luam tshwj xeeb. Yog li, folding tau siv hauv geology, botany, entomology thiab lwm yam haujlwm ntawm kev ua ub no. Hauv kev tshawb fawb hauv chaw kuaj ntshav, siv lub tswb nrov nrov, hauv kev phais - tsom iav.

Lub lens yog cov khoom tsim los ntawm cov khoom siv homogeneous pob tshab. Nws suav nrog ob qhov chaw, ib qho tuaj yeem yog kheej kheej lossis kheej kheej, thiab lwm qhov kheej kheej lossis tiaj tus. Iav, quartz, muaju thiab yas tau siv los ua tus tsom iav.

Cov yam ntxwv tseem ceeb ntawm lub lens yog:

• focal ntev;
• lub vojvoog ntawm tus kheej;
• refractive index.

Cov lo ntsiab muag tau hloov pauv thiab nthuav dav . Thawj hom yog siv hauv kev yees duab thiab khoom siv yees duab, hauv kev tsim cov tsom iav tsom iav, tab sis qhov thib ob yog siv tshuaj, tshwj xeeb hauv kev kho qhov muag.

Diffusion lo ntsiab muag tau teeb tsa hauv txhua lub tsom iav.

Qhov sib txawv tseem ceeb

Tau kawg, muaj ntau qhov sib txawv ntawm tus tsom iav thiab lub lens, txawm hais tias lub lens yog ib qho ntawm lub tsev thaiv ntawm tus tsom iav.

Tshwm sim . Tej zaum txhua tus paub tias lub iav tsom iav zoo li cas - nws yog iav tsom iav, uas tau muab tso rau hauv tus thav duab nrog tus kov. Nws yog qhov yooj yim heev los tuav nws hauv txhais tes, thaum tsom mus rau qhov khoom uas xav tau nthuav dav. Tab sis lub lens zoo li iav zoo tib yam, cov duab uas tuaj yeem sib txawv - nws txhua yam nyob ntawm nws hom.

Daim ntawv thov . Lub iav tsom iav feem ntau yog siv los nthuav qee yam khoom lossis kab ntawv: thaum nyeem cov ntawv, rau cov khoom siv tes ua, thiab ntau yam nws tuaj yeem siv rau lwm yam tshaj li nws lub hom phiaj xav tau, piv txwv li ua hluav taws, hlawv qhov txhab, hlawv ntawv lossis kos duab., ua kom cov yas nto los ntawm yaj lawv. Tab sis lo ntsiab muag muaj ntau yam siv. Lawv tau teeb tsa hauv ntau yam khoom siv kho qhov muag, siv tshuaj, siv xov tooj cua astronomy, thiab txawm tias siv riam phom nuclear.

Txoj haujlwm ua haujlwm . Tus tsom iav tau tsim los txhawm rau kom pom lub kaum ntse ntse. Txhawm rau ua qhov no, cov khoom nyob hauv kev tshawb nrhiav yuav tsum tau muab tso nruab nrab ntawm lub iav tsom iav thiab nws lub hom phiaj. Cov cuab yeej nqus cov teeb pom kev thiab nthuav cov duab. Lub lens, vim yog nws lub ntsej muag nkhaus, ua rau lub teeb pom kev zoo thiab tseem nthuav cov khoom. Los ntawm txoj kev, yog tias koj siv lub lens sib sau, cov duab ntawm cov ncauj lus yuav hloov pauv.

Dab tsi zoo dua?

Tsis muaj txoj hauv kev los muab cov lus teb meej rau cov lus nug uas zoo dua: iav tsom iav lossis tsom iav. Txhua tus txiav txim siab rau nws tus kheej tias yam khoom siv kho qhov muag nws xav tau dab tsi. Qhov tseem ceeb tshaj plaws yog xav txog:

• hauv kev lag luam twg thiab rau lub hom phiaj twg nws xav tau;
• cov yam ntxwv tseem ceeb ntawm lub iav tsom iav xws li qib kev nthuav dav, ntev focal, thaj chaw pom.

Tsis tas li, tsis txhob hnov qab txog cov kev xaiv raws li qhov zoo ntawm lub cuab yeej kho qhov muag. Nws yuav tsum tau xa cov xim kom zoo, tiv taus cov khoom siv dag zog.

Niaj hnub no, yuav lub iav tsom iav lossis tsom iav tsis yog teeb meem txhua. Lawv raug muag ntawm ntau lub ntsiab lus tshwj xeeb ntawm kev muag. Nws yog qhov zoo tshaj plaws, tau kawg, muab kev nyiam rau cov tuam txhab nto moo tshaj plaws.
