Gyrocompass, navigational instrument uas ua rau siv a txuas ntxiv tsav gyroscope kom raug nrhiav qhov tseeb (geographic) sab qaum teb. Nws ua haujlwm los ntawm kev nrhiav kev sib npaug ntawm kev coj ua raws li kev sib koom ua ke ntawm lub zog ntawm lub ntiajteb txawj nqus thiab kev sib hloov txhua hnub ntawm lub ntiaj teb.
Qhov twg thiab vim li cas koj thiaj siv lub gyrocompass?
Gyroscopes yog siv rau hauv compasses thiab tsis siv neeg tsav tsheb ntawm cov nkoj thiab dav hlau, nyob rau hauv lub steering mechanisms ntawm torpedoes, thiab nyob rau hauv lub inertial kev taw qhia systems ntsia nyob rau hauv qhov chaw tso tsheb, ballistic missiles, thiab orbiting satellites.
Lub hom phiaj ntawm gyro yuam kev yog dab tsi?
Qhov yuam kev hauv kev nyeem ntawv ntawm gyro compass, qhia nyob rau sab hnub tuaj lossis sab hnub poob taw qhia qhov kev taw qhia uas lub axis ntawm lub compass yog offset los ntawm sab qaum teb.
Gyrocompass hauv nkoj yog dab tsi?
A Gyro compass yog a daim ntawv ntawm gyroscope, siv dav hauv cov nkoj uas siv hluav taws xob siv hluav taws xob, nrawm-spinning gyroscope log thiab kev sib txhuam ntawm lwm yam uas siv cov kev cai hauv lub cev, Kev cuam tshuam ntawm lub ntiajteb txawj nqus thiab lub ntiaj teb kev hloov mus nrhiav qhov tseeb sab qaum teb.
Dab tsi yog qhov sib txawv tseem ceeb ntawm gyrocompass thiab magnetic compass?
Gyrocompasses tau siv dav rau kev taug kev ntawm cov nkoj, vim tias lawv muaj ob qhov txiaj ntsig zoo ntawm cov hlau nplaum sib nqus: lawv pom qhov tseeb sab qaum teb raws li kev txiav txim siab ntawm lub axis ntawm lub ntiaj teb kev sib hloov,uas txawv ntawm, thiab navigationally muaj txiaj ntsig ntau dua, sib nqus sab qaum teb, thiab.

Vim li cas peb thiaj siv steradian?
A steradian yog siv los ntsuas "lub kaum ntse ntse" tib yam li tus radian cuam tshuam nrog lub voj voog ntawm lub voj voog: Ib Radian "txiav tawm" qhov ntev ntawm ib lub voj voog lub voj voog sib npaug rau lub vojvoog. equal to (radius) 2.
Vim li cas peb thiaj xav tau cov khoom siv hluav taws xob decoupling?
Ib lub decoupling capacitor ua raws li lub zog hluav taws xob hauv zos reservoir. Capacitors, zoo li cov roj teeb, xav tau sijhawm los them thiab tso tawm. Thaum siv los ua decoupling capacitors, lawv tawm tsam kev hloov pauv sai ntawm voltage.
Vim li cas peb thiaj siv novaculite?
Novaculite, tseem hu ua Arkansas Pob zeb, yog microcrystalline rau cryptocrystalline pob zeb hom uas muaj silica hauv daim ntawv ntawm chert lossis flint. Nws feem ntau yog xim dawb rau grey lossis xim dub, nrog rau lub ntiajteb txawj nqus tshwj xeeb ntawm 2.
Vim li cas peb thiaj siv audiometry?
Audiometry tests tuaj yeem nrawm seb koj puas hnov lus tsis hnov tsw(kev puas tsuaj rau lub paj hlwb lossis cochlea) lossis kev hnov lus tsis zoo (kev puas tsuaj rau pob ntseg lossis pob txha pob txha me me). Thaum lub sij hawm kev ntsuam xyuas audiometry, ntau yam kev xeem yuav raug ua.
Vim li cas peb thiaj siv ohm meter?
Ib ohmmeter yog ib qho khoom siv hluav taws xob ntsuas hluav taws xob tiv thaiv (kev tawm tsam muab los ntawm cov khoom siv rau qhov ntws ntawm hluav taws xob tam sim no). … Micro-ohmmeters (microhmmeter lossis micro ohmmeter) ua rau qhov ntsuas tsis zoo.
