Kev paub txog kev tsim cov hlua khi thiab sib dhos rau cov khoom siv tshwj xeeb

Kev xyaum tau ua pov thawj tias nws yuav siv sij hawm tsawg kawg yog ib hnub lossis ntau lub sijhawm rau cov khoom siv hluav taws xob nruab nrab los ntsuas nws cov kab hluav taws xob los ntawm cov lus pom zoo (multimeter thiab buzzer ua ke nrog cov ntsuas hluav taws xob), thiab nws tuaj yeem ua tiav cov haujlwm sim hauv ob peb feeb. los ntawm kev siv cov hlua hluav taws xob tsim kev sim ntsuas qhov system. Nws tuaj yeem xav txog tias qhov kev cuam tshuam ntawm kev siv hluav taws xob tsis siv neeg thaiv kab hluav taws xob yog qhov kev hloov pauv hloov mus rau qhov system cabling nrhiav kom tau thev naus laus zis.
Vim yog cov qauv tshuaj sib txawv ntawm cov khoom siv polymer, lub peev xwm ntawm hluav taws xob polymerization yog qhov sib txawv heev, qee qhov feem ntau degradation, qee qhov feem ntau yog crosslinking. Txawm tias tus ntoo khaub lig-txuas polymer yog nrog los ntawm kev tawg ntawm cov saw tseem ceeb, yog li lub sij hawm irradiation thiab koob tshuaj yuav tsum nruj me ntsis tswj kom ua tiav qhov zoo tshaj plaws crosslinking degree. Rau crosslinked polymer, qhov crosslinking degree nce nrog qhov nce ntawm irradiation lub sij hawm thiab koob tshuaj.
Lub kaw lus muaj peb ntu: qhov chaw ib feem ntawm satellite constellation, hauv av tswj ib feem hauv av saib xyuas qhov system thiab cov neeg siv khoom siv ib feem ntawm lub teeb liab receiver. Nrog txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no, lub ntiaj teb qhov chaw tso qhov system (GPS) yog ntau qhov kev ua haujlwm ntawm kev ua haujlwm siab, tag nrho cov huab cua thiab thoob ntiaj teb xov tooj cua navigation, qhov chaw thiab sijhawm. Nws siv cov kwj deg tsis tu ncua ntawm cov cim qhia uas muaj ntau dua 20, 000 mais saum lub ntiaj teb. Ib lub receiver nyob rau hauv lub ntiaj teb, tsuav yog nws tau txais ntau tshaj plaub satellite signals, tom qab xam, koj yuav tau txais lub receiver txoj hauj lwm (longitude, latitude, altitude) lub sij hawm thiab lub xeev cov lus qhia. Lub kaw lus muaj cov yam ntxwv ntawm kev ua haujlwm siab, txhua qhov huab cua, kev ua haujlwm siab, kev ua haujlwm ntau, kev ua haujlwm yooj yim thiab daim ntawv thov dav.
Kev txiav txim siab ntawm ceg sib dhos ua ntu zus ntawm cov hlua khi tsim yog ua raws li kev txheeb xyuas ntawm ceg ntawm cov hlua khi thiab nws cov kev cuam tshuam rau kev ua haujlwm ntawm lub cev. Lub hauv paus ntsiab lus ntawm kev sib txuas ntawm cov hlua khi hauv engineering feem ntau yog lub cev ua ntej cov ceg, thiab cov hlua hlua khi nrog cov kev cai tshwj xeeb yuav tsum tau kho kom haum raws li qhov xav tau. Raws li lub hauv paus ntsiab lus ntawm kev sib dhos ntawm lub cev thawj zaug thiab ceg thib ob, cov hlua khi hlua khi tau txiav cov txheej txheem los ntawm txheej, thiab tom qab ntawd tus txheej txheem tsim kho cov txheej txheem sib dhos ntawm cov hlua hlua khi nrog cov kev cai tshwj xeeb raws li kev paub dhau los thiab kev paub dhau los, kom tau txais qhov pom kev xaim hlua khi ceg sib dhos ua ke.
Cov chromium plated steel sawb thiab tinned steel sawb raus hauv hydrochloric acid rau 20 hnub, cov txiaj ntsig ntawm chromium plated steel sawb tsuas yog ntug corrosion, thiab tinned steel sawb corrosion hnyav, zaj duab xis tawm tag, chromium plated steel sawb thiab tinned steel sawb raus. nyob rau hauv 75 degrees rau 7 hnub, cov txiaj ntsig ntawm chromium plated steel sawb tsis hloov pauv, uas yog, muaj kev sib raug zoo heev, thiab tinned steel strip polymer zaj duab xis muaj ntau cov npuas me me, thiab lub sijhawm ntev dua, cov npuas ntau, uas. Yog hais tias, nyob rau hauv cov xwm txheej no, lub compatibility ntawm tinned steel sawb thiab bundle paste yog tsis zoo.
Kev sib txuas ntawm cov khoom siv hluav taws xob yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm kev sib dhos hluav taws xob. Ntxiv nrog rau cov cuab yeej siv hluav taws xob ntawm cov hlua hluav taws xob tsim, kev ntseeg siab ntawm cov khoom siv hluav taws xob sib txuas hauv lub cev, xws li kev sib txuas thiab kev tiv thaiv lub zog ntawm cov nodes, yog qhov tseem ceeb tshaj plaws ntawm txoj haujlwm no.
