Cov Hlau Hlau Qws, yog hais txog cov hlau uas tau kub-dov hauv lub tshuab zeb hlau qws thiab tom qab ntawd coiled rau hauv ib lub kauj. Nws cov yam ntxwv tseem ceeb suav nrog cov hauv qab no:
1. Cov duab tshwj xeeb, yooj yim rau kev thauj mus los thiab cia khoom

Piv rau cov hlau ncaj, cov hlau kub dov hauv daim ntawv coiled tuaj yeem muab tso ua ke ntau hauv qhov chaw tsawg, txo qhov chaw siv thaum thauj mus los thiab khaws cia. Piv txwv li, Cov Hlau nrog txoj kab uas hla 8 hli tuaj yeem dov rau hauv lub disc kwv yees li 1.2-1.5 meters hauv txoj kab uas hla, hnyav ntau pua kilograms ib lub disc. Qhov no ua rau kev nqa thiab kev thauj mus los ntev, ua rau nws tsim nyog rau kev faib khoom lag luam loj.
2. Kev ua tau zoo heev thiab daim ntawv thov dav dav

Cov hlau xaim kub dov yog ua los ntawm ntau yam khoom siv (xws li cov hlau uas tsis muaj carbon, cov hlau uas muaj carbon ntau, thiab cov hlau sib xyaw). Tom qab dov kub, nws muaj cov yas zoo heev thiab tawv, ua rau nws yooj yim rau kev ua. Cov txheej txheem ua khoom siv feem ntau suav nrog kev kos duab txias (los tsim cov hlau), kev ncaj thiab txiav (los tsim cov khoom siv xws li bolts thiab rivets), thiab kev sib txuas (los tsim cov hlau mesh thiab cov hlua hlau). Nws yog siv dav hauv kev tsim kho, kev tsim khoom siv tshuab, kev lag luam tsheb, thiab cov khoom siv hlau.

3. Kev Ntsuas Qhov Siab thiab Qhov Zoo Tshaj Plaws
Cov tshuab ua hlau niaj hnub no tuaj yeem tswj tau qhov kam rau ntawm txoj kab uas hla ntawm cov hlau hlau (feem ntau yog nyob hauv ± 0.1 hli), kom ntseeg tau tias cov khoom sib xws. Ntxiv mus, kev tswj qhov txias thiab kev kho qhov chaw thaum lub sijhawm dov ua rau muaj qhov chaw du thiab qis. Qhov no tsis yog tsuas yog txo qhov xav tau kev txhuam tom qab xwb tab sis kuj txhim kho qhov zoo sib xws ntawm cov khoom kawg. Piv txwv li, qhov zoo ntawm qhov chaw ntawm cov hlau hlau hlau siab siv hauv kev tsim khoom caij nplooj ntoos hlav cuam tshuam ncaj qha rau lub neej qaug zog ntawm lub caij nplooj ntoos hlav.
