Meteorological balloons, raws li ib lub tsheb rau cov pa high-altitude huab cua nrhiav kom tau, yuav tsum tau ib tug tej yam load thiab inflation rate.Raws li lub premise, lub lift-off qhov siab yuav tsum siab npaum li sai tau.Yog li ntawd, nws cov yam ntxwv tseem ceeb yog raws li nram no:
(1) Cov duab geometric zoo dua.Txhawm rau txo qis kev cuam tshuam ntawm huab cua tsis kam thiab airflow thaum lub sij hawm nce siab ntawm huab cua balloons (tshwj xeeb tshaj yog lub suab nrov balloons), cov duab geometric ntawm lub zais pa yuav tsum zoo ib yam li cov duab streamlined, thiab lub suab nrov balloon yuav tsum tsis yog lub voj voog zoo meej lossis ib ellipse.Rau lub suab nrov, tus kov yuav tsum tuaj yeem tiv taus lub zog rub ntawm 200N yam tsis muaj kev puas tsuaj.Txhawm rau txo qhov muaj peev xwm ntawm tus kov raug rub tawm, lub thickness ntawm lub pob yuav tsum tau maj mam nce mus rau qhov kov.
(2) Cov tawv nqaij pob yuav tsum sib npaug thiab tiaj tus.Qhov chaw uas lub thickness dheev dhau los ua nyias yuav ua rau muaj teeb meem.Yog li ntawd, qhov kev tshuaj ntsuam xyuas thiab thickness ntsuas ntawm huab cua balloons yog qhov tseem ceeb tshwj xeeb.Lub zais pa yuav tsum tsis txhob muaj qhov tsis sib xws, npuas, impurities, thiab lwm yam uas cuam tshuam rau kev nthuav dav, thiab tsis muaj qhov, tawg, thiab lwm yam. Cov tsos ntawm cov teeb meem loj xws li cov roj stains thiab khawb ntev.
(3) Kev tiv thaiv txias yog zoo dua.Cov huab cua balloon yuav tsum dhau los ntawm qhov chaw txias txias qis dua -80 ° C thaum lub sijhawm nqa tawm.Qhov kev nce nqi ntawm lub zais pa hauv cheeb tsam no txiav txim siab qhov kawg ntawm qhov siab ntawm lub zais pa.Qhov siab dua qhov elongation tus nqi ntawm lub zais pa ntawm qhov kub thiab txias, qhov loj dua qhov nthuav qhov sib piv.Qhov siab ntawm lub zais pa yuav siab dua.Yog li ntawd, nws yog ib qho tsim nyog yuav tau ntxiv cov softener nyob rau hauv zus tau tej cov latex balloons kom lub zais pa ntawm daim tawv nqaij yuav tsis khov thiab harden thaum lub zais pa ntsib qhov kub thiab txias nyob ze ntawm lub tropopause, thiaj li yuav ua rau kom lub elongation thiab tawg txoj kab uas hla ntawm lub balloon nyob rau hauv qis kub. , yog li nce lub balloon nqa-tawm.qhov siab.
(4) Muaj zog tiv thaiv hluav taws xob aging thiab ozone aging.Huab cua balloons yog siv thaum lub ozone concentration siab.Lub ozone concentration nce mus txog qhov siab tshaj plaws ntawm 20000 ~ 28000 meters los ntawm hauv av.Cov hluav taws xob ultraviolet muaj zog yuav ua rau cov yeeb yaj kiab tawg, thiab qhov ntev ntev ntawm lub hnub ci tseem yuav ua rau cov yeeb yaj kiab nrawm dua.Lub zais pa nthuav dav raws li qhov ntom ntom ntawm cov huab cua txo qis thaum lub sijhawm nqa tawm.Thaum nws nce mus txog 30,000 meters, nws txoj kab uas hla yuav nthuav dav mus rau 4.08 npaug ntawm qhov qub, thaj chaw saum npoo nthuav dav mus rau 16 npaug ntawm qhov qub, thiab cov tuab yog txo kom tsawg dua 0.005mm., Yog li ntawd, lub zais pa tiv thaiv hluav taws xob aging Thiab ozone aging kuj yog qhov tseem ceeb ntawm lub zais pa.
(5) Kev ua haujlwm khaws cia zoo dua.Los ntawm kev tsim khoom siv, huab cua balloons feem ntau siv sijhawm 1 txog 2 xyoos lossis ntev dua.Qhov kev ua haujlwm tseem ceeb ntawm cov balloons tsis tuaj yeem txo qis thaum lub sijhawm no.Yog li ntawd, huab cua balloons yuav tsum muaj kev cia khoom zoo thiab cov ntsiab lus calcium chloride seem nyob rau saum npoo ntawm lub zais pa.Nws yuav tsum tau tsawg li tsawg tau kom tsis txhob adhesion ntawm pob tawv nqaij nyob rau hauv cov huab cua ntub.Hauv thaj chaw sov (lossis lwm qhov kub thiab txias), feem ntau yuav tsum khaws cia rau 4 xyoos.Yog li ntawd, cov balloons yuav tsum tau ntim rau hauv ib lub teeb-pov thawj pob kom tsis txhob raug lub teeb (tshwj xeeb tshaj yog tshav ntuj), huab cua los yog huab cua kub heev.Txhawm rau tiv thaiv kev ua haujlwm zais pa kom poob qis sai.
