Cov xwm txheej ua haujlwm ntawm qhov hloov pauv yuav tsum tau them sai sai rau qhov kub thiab txias. Cov nyhuv ntawm qhov kub thiab txias ntawm qhov hloov pauv ua lub luag haujlwm tseem ceeb heev. Raws li qhov ntsuas kub tsim nyog thiab tsim nyog, peb tuaj yeem ua rau peb cov cuab yeej ua haujlwm tau zoo thiab ua rau peb cov cuab yeej siv xov tooj tsim nyog thiab siv tau.
Nyob rau hauv lub neej tiag tiag, lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm kov lub hloov yog yooj yim heev, tab sis muaj ib co kev cai. Thaum siv cov cuab yeej no, peb yuav tsum xub saib seb nws ua haujlwm li cas. Txwv tsis pub, nws yuav tsis ua rau nws zoo siab thiab siv. Qhov kub siab tshaj plaws ntawm cov khoom siv yuav tsum tsis pub tshaj 40 degrees. Thaum siab tshaj 40 degrees, nws yuav ua rau muaj kev puas tsuaj loj thiab txo qis, thiab qhov kub thiab txias yuav tsum tsis pub tsawg tshaj 5 degrees. Thaum qis dua 5 degrees, kuj tseem yuav muaj kev cuam tshuam tsis zoo thiab kev tawm tsam loj, uas tuaj yeem cuam tshuam tsis zoo rau peb cov khoom siv hluav taws xob thiab hluav taws xob. Cov nyhuv ntawm lub ntsej muag, yog li hauv lub neej tiag tiag, peb yuav tsum tau them sai sai rau nws qhov kub thiab txias. Nws tsuas tuaj yeem ua rau qhov kub thiab txias, nws tuaj yeem them taus thiab kev hlub, thiab tuaj yeem siv tsim nyog.
Lub teeb kov hloov hluav taws xob no tseem tuaj yeem siv rau ntawm qhov siab siab. Nws tuaj yeem pom tau tias nws muaj kev hloov pauv siab, kev hloov pauv muaj zog heev tau nyiam cov neeg coob coob, thiab kev hloov pauv muaj zog heev kuj tseem ua rau nws tsis muaj kev txwv thiab siv. Tab sis nws yog qhov zoo tshaj kom tsis txhob nruab ntau tshaj ob kilometers. Tom qab ob kilometers, yuav muaj ntau yam tsis zoo. Hauv lub neej tiag tiag, huab cua kub ntawm lub cuab yeej yuav tsum tau teeb tsa kom tsim nyog. Nws muaj qee qhov kev ua qias tuaj thiab ua rau muaj kuab paug rau cov khoom siv hluav taws xob, yog li nws yuav tsum tsim nyog. Hauv kev siv tswv yim, nws yog qhov zoo tshaj plaws kom txo cov pa phem thiab maj mam txhim kho nws daim ntawv thov.
Lwm qhov tshwj xeeb ntawm kev kov qhov hloov yog tias nws cov qauv tsim ua tau raws li qhov yuav tsum tau ua ntawm cov cuab yeej tsim khoom, uas tuaj yeem maj mam tawg los ntawm kev lag luam ib txwm muaj thiab maj mam ua tiav kev tsim kho tshiab. Tus nqi ntawm cov khoom no yog siab. Tsis muaj cov txheej txheem tsis xws luag nyob rau hauv lub switching Circuit Court thiab muaj zog. Cov khoom lag luam muaj kev thov dav dav. Cov qauv kev thov tag nrho yog ntau classic thiab yuav qhia cov ntsiab lus ntawm cov khoom zoo li no rau peb. Yog tias koj tsis paub yuav ua li cas siv cov khoom no hauv lawv lub neej.
Qee qhov me me high-tech lub teeb kov hloov daim ntawv thov yog siab heev. Qee lub teeb kov hloov hluav taws xob yuav tsum tau siv dav. Cov teeb, high-tech, thiab cov nqi siab-ntxiv cov khoom me me yuav tau txais kev mloog ntau dua thiab siv rau hauv lub neej yav tom ntej.
