Nazzomi meteori

Nazzomi meteori (az ar.— tezchashm, durbin, daqiqbin va meteorho) yak sistemai agregathoi fotografist, baroi mushohidai meteor (shihob)-ho. Har yak agregati Nazzomi meteori odatan az 4—6 kamerai fotografii farokhzoviya iborat ast. Kamerahoro tavre joy medihand, ki onho yakhoya qismi haddalimkon kalontarini osmonro dar bar girifta tavonand.

Macalan, Nazzomi meteorii Instituti astrofizika i AF RSS Tojikiston az 4 agregat iborat ast, ki har kadomash 6-toi kamerai fotografi (diametri obektivash D = 10 sm, masofai fokusi (qonuni)-ash F = 25 sm) dorad. Onho yakjoya qismi osmonro az zenit to masofai zenitii 50—55° ba hama taraf dar bar megirand. Dar mahalli asosi 3 agregat guzoshta shudaast: yake az onho bo montirovkai ekvatori dar montirovkai parallaksii teleskop (montirovkai on qismi teles­kop, ki ba on gulbai mushohida shinonda meshavad) tamin shuda­ast, ki baroi ba dast ovardani tasviri nuqtagii sitoraho imkoniyat medihad; dar peshi obektivhoi agregati duyum obtyuratori duparra joy doda meshavad, ki bo surati 1500 gard/daq charkh zada, dar navor izi munfasili meteorro hosil me­kunad: dar peshi obektivhoi agrogati seyum baroi giriftani surati spektri meteor prizmahoi kunji shiokanishashon 25° shinonda shudaand. Agregati chorum az agregathoi digar dar masofai 34 km guzoshta shudaast.

Korkardi yakjoyai surathoe, ki hamai agregathoi Nazzori meteori giriftaand, baroi muayyan namudani lahzai parvozi meteor, balandi (bo sahehii ±100 m), surat (bo sahehii 0,4%), radiant (bo sahehii to 3^′), massavu tarkibi khimiyavii on imkoniyat medihad. Bo maqsadi har chi beshtar giriftani surati meteorho osmonro tamomi shab mushohida mekunaid (kadrho badi har 0,5—1 s ivaz kar­da meshavand). Nazzori meteorii Instituti astrofizikai AF RSS Tojikiston boz du agrega­ti ilovagie dorad, ki onho yakjoya az 16 kamerai fotografii darozkonuna (F = 75 sm, D: F = 1: 3,5) iborat buda, baroi bo metodi ekspozitsiyahoi lahzagi (0,56 ∙  son) gi- riftani surathoi umumi va spekt- ri meteorho khizmat mekunand.
