Qhov Zoo Ntawm Projecting Ib Daim Ntawv Qhia Hniav Lawm Sib Piv rau Lwm Cov Ntawv Sib Nqus Compasses
Jun 23, 2018| Projection hlau nplaum, piv txwv li cov tshuab hluav taws xob hauv tshuab hluav taws xob, pom tau qhov kev taw qhia ntawm lub nkoj los ntawm kev ua haujlwm. Lub projection sib nqus compass yog tsim rau qhia txog kev taw qhia ntawm kev taw qhia kev taw qhia rau ntau lub nkoj. Lub feature ntawm lub tshuab raj magnetic compass yog tias nws yuav siv tau raws li tus qauv sib nqus compass, nws kuj siv tau ua ib lub kauj vab, qhov siab ntawm lub lens phom yuav arbitrarily kho, thiab nws tseem yuav tig sab laug thiab txoj cai. Cov txheej txheem rau projecting ib lub tshuab hluav taws xob ntau yog tsim los ntawm ib qho kev sibtham hluavtaws (magnetic compass) thiab ib lub kauj (steering device). Lub installation ntawm ib qhov kev sib tw ntawm hlau nplaum yuav ua kom haum raws li cov lus qhia tau muab. Thaum txhim kho, nws yog qhov tsim nyog yuav tau them sai sai rau qhov kev sib txuas kom yog ntawm lub hwj chim. Yog hais tias lub zog rov qab, lub tshuab fuse yuav raug ntaus. Tom qab tshuab, lub fuse yuav tsum tau hloov. Thaum tsis siv ib lub tshuab nplaum hlau nplaum, nws yog qhov yuav tsum tau muab lub hwj chim rau lub dispenser. Plug ntawm lub dispenser yog ib qho laub rov qab. Thaum ntsaws lub hau ntsaws, qhov ntsaws tsis tuaj yeem hloov.
Thaum lub sij hawm txhua lub voyage, nws yog ib qhov tsim nyog yuav tau ua tib zoo xyuas lub projection magnetic compass thiab tom qab ntawd sau nws hauv phau ntawv teev npe. Vim li cas peb thiaj li yuav tsum tau xyuas thiab sau cov cav? Qhov no yog los xyuas kom meej siv qhov sib nqus ntawm lub tshuab hluav taws xob, thiab txhua cov ntaub ntawv tseem ceeb heev rau xam cov sib txawv ntawm qhov sib txawv thiab kev kho tus kheej.
