Indlela ukukhetha ngemicroscope ukuze umfundi?

Uluhlu zipho zixabisekileyo umntwana kufuneka ngokuqinisekileyo zibandakanya izixhobo zophando lwezenzululwazi. Kakade ke, sithetha ngalo andilociko kwaye, kananjalo, inqanaba zabantwana zokufunda yehlabathi ezingqongileyo. Kodwa ukuze babeke isiseko Umfundi ukwazi ukuba iya kuba yanele. Enye kakhulu umdla yaye kulula-to-ukusetyenziswa iinketho nezixhobo zomsebenzi ngemicroscope. imifuziselo zangoku ngokulungelelanisiweyo oludibanisa lula ukusetyenziswa kunye nokusebenza eliphezulu. Noko ke, ukuba ukujonga ukukhetha indlela neemicroscope ukuba umfundi, kufuneka uqwalasele izicwangciso ezahlukeneyo kulo matshini. Nangona abenzi ukukhulula umgca ezizodwa imifuziselo zabantwana, nditsho phakathi kwezi ukhetho kunokuba iingxaki ezithile.

Yintoni imifuziselo abantwana ezizodwa ngayo?

Ngokuqhelekileyo abantwana analogs izixhobo kunye nezixhobo elungiselelwe abantu abadala ziyalungiswa ngobulungisa wokwakha. Oku kuyinyaniso iimikroskopu, nangona iseti iindawo candelo esetyenziswayo iyafana - oko umnini eyepiece, ixilongo elikhulu lebhasi, lenses, kwaye olunamagama eqongeni. Kuxhomekeka imodeli, kuba ngemicroscope umfundi unokuba iimpawu ezahlukeneyo zezi zinto, kodwa bonke swi nasekuxhatshazweni kwinqanaba lokuqala entsonkothileyo.

Kufuneka kwakhona ikhunjulwa into yokuba imodeli ayide ikwazi azinakufaniswa izixhobo eziphakamileyo-grade kwi ubuninzi ekwandiseni. Izinga lincinane olu khetho yi buhlanti-40, yaye abangakwaziyo embindini izixhobo abantwana zifumaneka izixhobo 600 oluphindwe- sikrini. Ukukhetha le Uphawu kufuneka kwenziwe, ngokusekelwe ekusetyenzisweni imibuzo. Ukongezelela koko, ngokuba neemicroscope umfundi zinokwahluka uyilo bokuqonda obubonakaliswa ngokohlobo uyilo kunye nemibala. Musa ukulibala ukuba sithetha ngabantwana, kunye nokusebenza yangaphandle neemicroscope nayo ibalulekile.

Iintlobo iimikroskopu ukuze umfundi

Kuyinto nangoku imifuziselo zixhaphakileyo elektroniki, ezo baxhotyiswa lens electrostatic ngemagnethi. Kodwa lo izixhobo ayikwazi kubizwa ngokuba uqeqesho, ekubeni unalo ithuba ophezulu ukwanda, olunokuba yomfundi ezandleni kwemfuneko. kwezixhobo Ngokuqhelekileyo monocular ezikhethiweyo ukusetyenziswa enjalo, apho isixhobo elula, kodwa kwangaxeshanye ukumelana neengxaki zenkqubo yemfundo. Ubhalo ncomo khulu yesikolo eziphilayo abathi ukusebenza kunye namathuba nasekufundweni iiseli. Mhlawumbi kakhulu ukusebenzisa ithekhinoloji ingabizwa isixhobo eyodwa apho lixhotyiswe lenses ezimbini. Le modeli kuba nomtsalane kuphela bunokulolongeka elula into efundwayo, kodwa ubukho yokukhanyisa, nto leyo enika umfanekiso umgangatho kucaca lens.

uhle Digital

ingqalelo eyodwa yanikwa isixhobo i-digital. Ngoko nangoko kufanele kuqatshelwe ukuba kukho le yenziwe kakhulu ibiza kakhulu kuyaphi kunezixhobo zemveli, kodwa usebenziso lwayo ubaluleke ngayo. Uphawu lwe ifowuni kukukwazi ukuqhagamshela ikhompyutha okanye zekhamera nge-USB interface. Oku kuthetha ukuba ngemicroscope yedijithali ukuba umfundi angathumela ngqo iziphumo lokuqaphela kwimidiya okhethekileyo. Ngokuqhelekileyo, ezifana uguqulelo baxhotyiswa imiboniso digital kunye ilayithi LED. Kuba iimfuno zemfundo ukhetho olunjalo abo ukuba umfundi uya kukwazi kakuhle ngokulula ukusebenza isixhobo, kunye nokukwazi ukuba abhale izinto kuya kuvumela ukuba kuqhubeka isifundo, nasemva ugqityiwe umsebenzi ngefoni.

Yintoni ukuqwalasela kwinkqubo yokhetho?

Okokuqala, simele sicinge umgangatho nokusebenza kunye kwindawo eziphathekayo ngayo. Izindlu inokuba zeplastiki okanye intsimbi. iiplastiki Modern eqinile, kodwa kwakhona ivumela ubunzima ukukhanya imveliso. isixhobo metal okuhlala, kodwa kunzima ngakumbi ukuba umntwana yokusingatha. Lens kunye lenses kufuneka zenziwe kuphela zeglasi - kwebambela amanani ngohlobo lweplastiki akufane inika umgangatho elungileyo. Kakhulu ubuninzi sele kuphawulwe ukuba ezi iimikroskopu ukuze abafundi bakwazi ukwandisa emehlweni akhe kwi-avareji amaxesha-40 ukuya 600. Kukho imifuziselo abonelela ireyithi ephezulu, kodwa akukho mfuneko yokuba kwinqanaba lesikolo. Kuninzi kakhulu kubalulekile ukuqwalasela ukuba usizo ifowuni. Umzekelo, zokukhanya kungcono ukukhetha ngokusekelwe ilight-esikhupha, kwaye iqonga ndlovu ukunika tabs ethembekileyo lula.

Abenzi iimikroskopu

Umgangatho kwaye zisebenza iimikroskopu ziveliswa phantsi brand Bresser. Kumnombo imveliso ungafumana iimatshini ukuba babe ukukhulisa oluphindwe-450, baxhotyiswa izixhobo digital kunye backlighting LED. Ukuba ufuna ukuze kuxhotyiswe lonke yilebhu lomfundi, kufuneka ukhethe ukuba ngemicroscope umfundi "Young Scientist" ukusuka Discovery umenzi. Le fowuni ine isakhiwo monocular lens ngezinga eliphezulu yongeniselo ukuya esibayeni-1200, nto leyo kungathathwa zincinci izinto iinkcukacha. Le modeli unalo inyanda ebanzi, ebandakanya amacandelo 60.

Ethile isisombululo umdla kunye nenkampani Eastcolight. Abenzi bemeko- nokubonelela ngeekhithi ezininzi eziquka kuphela ngemakroskopu ukuba umfundi, kodwa iteleskopu. Kwandisa nokubanako ubuninzi lokuqala 900, apho ikhithi ngakumbi liquka iseti yezibuko kunye lens, amashiya, magnifiers, abanini, iinaliti kunye ingadla yogqirha.

Eyongezwayo for khulu

Ukongeza kwizixhobo ezisisiseko, kwaye kufuna izixhobo ezongezelelweyo kunye zombane ukuququzelela nokugcinwa isixhobo, kwakunye nomsebenzi kuphando umsebenzisi abatsha. Oku kunokuquka izixhobo micropreparations kunye neemveliso zononophelo ngenxa yokukhanya. Kunqweneleka ukuba umfundi ukuba abe ngemicroscope kunye cleaner womoya, kufafazwa ezizodwa usula. Kuba lula usebenziso kwaye ayiyi kuba akufuneki ukubonelela njengezikhanyiso ezahlukeneyo, condensers kunye lenses eyepiece abangabancedani.

isiphelo

Ngokutsho models iimpawu umntwana iimikroskopu Akukho kude kakhulu ukusuka kunoogxa ezipheleleyo abadala. Nkqu umgangatho optic nokwandisa ubuchule layo ukuthintela ukubiza ezi zixhobo zokudlala. Kunjalo iimikroskopu ukuze abafundi kusafuneka ezinye umda ngokwalo functionality. Kwaye ke wabagwebelayo, ngenxa yokuba ukuqonda nezo imigqaliselo yemichiza eziphilayo kunokwenzeka kuphela emva kokusebenza kunye izixhobo entry-level. Inye kuphela ukuba sinayo xa ukhetha ngemicroscope isikolo - oko Akunakuba anobuchwepheshe kunye neendlela mihla ergonomics. Kaloku, ezi mpawu adityaniswa imifuziselo yedijithali.
