Thaum lawv rub qhov zoo G tus , cov suit inflates thiab tiv thaiv cov ntshav los ntawm pooling nyob rau hauv lawv ob txhais taw thiab ob txhais ceg uas yuav ua rau lawv tsis nco qab lawm. NASA cov neeg caij nkoj kuj hnav g - suits Thaum lawv ntsib Orthostatic Intolerance (OI).
Hauv qhov no, G suits ua los ntawm dab tsi?
Cov suit Qhov hnyav ntawm qhov nruab nrab 6.5 kilograms (14 lb) tag nrho, thiab nws cov ntaub yog ua tawm ntawm ib qho kev sib xyaw tshwj xeeb ntawm Twaron thiab Nomex. Cov nyhuv counter siab tshwm sim sai sai yam tsis muaj sijhawm ncua sijhawm piv rau ib qho nce mus rau ob lub vib nas this ua ntej ncav cuag kev tiv thaiv tag nrho hauv standardpneumatic, inflatable g - suits.
Ib yam li ntawd, pes tsawg G tus neeg tuaj yeem nqa tau? Ib tug neeg raug ua tau nqa kb5g0(49 m/s2) (txhais tau tias qee tus neeg yuav dhau mus thaum caij tsheb kauj vab siab dua-g, uas qee zaus tshaj qhov taw tes no) ua ntej tsis nco qab, tab sis los ntawm kev sib xyaw ua ke ntawm g-suits tshwj xeeb thiab kev siv zog rau cov leeg nqaij-ob qho tib si uas ua rau kom ntshav rov qab mus rau hauv lub cev.
Qhov thib ob, yog vim li cas G suit tau tsim?
Xyoo 1941, Dr. Wilbur Franks, ib tug ntawm cov kws tshawb fawb ntawm Banting lub koom haum, tau tsim kev ya. suit txhawb nqa nrog cov kua dej los pab cov kws tsav dav hlau tiv taus qhov huab cua G (gravitational) rog tawm ntawm lawv lub cev thaum sib ntaus sib tua.
Muaj pes tsawg G's yog ib lub dav hlau fighter?
Fighter dav hlau tuaj yeem rub mus txog 9 g vertically, thiab ntau tus kws tsav dav hlau tuaj yeem coj yam tsis muaj kev tawm tsam, qhov zoo dua lawv txoj hauv kev hauv dogfight. Qee tus kws tsav dav hlau hnav " g -suits” uas pab thawb cov ntshav tawm ntawm lawv ob txhais ceg thiab mus rau lub hlwb. Cov neeg siab tshaj g kam rau ua yog hu ua " g -monsters".

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi ntawm Endomycorrhizae ua Glomeromycetes muaj thiab dab tsi tshwj xeeb txog nws?
Glomeromycetes tsim mycorrhizae. Txawm li cas los xij, lawv yog ib pab pawg tseem ceeb ntawm kev lag luam. Tag nrho cov glomeromycetes tsim symbiotic mycorrhizae nrog cov cag ntoo. Mycorrhizal fungi tuaj yeem xa cov phosphate ions thiab lwm yam minerals rau cov nroj tsuag. Hauv kev sib pauv, cov nroj tsuag muab cov fungi nrog cov organic as-ham
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
S sawv rau dab tsi thiab dab tsi tshwm sim hauv theem no?
S theem sawv rau 'Synthesis'. Qhov no yog theem thaum DNA replication tshwm sim. The G2 stage stands for 'GAP 2'
