Cov lus tshwj xeeb thiab cov rooj loj
Ntsia yog lub ntsiab ntawm railway lem. Lawv txoj haujlwm yog los coj cov log ntawm locomotives thiab cov tsheb pem hauv ntej, dais lub siab loj ntawm lub log, thiab kis nws mus rau lub furgers. Cov ntsia yuav tsum tau muab txuas ntxiv mus ntxiv, du thiab tiv taus rolling nto rau lub log. Hauv cov hluav taws xob kev tsheb nqaj hlau lossis cov kev thaiv hluav taws xob tsis siv neeg, cov kab hlau tseem tuaj yeem ua haujlwm raws li taug qab ncig.
Hom kev tsheb ciav hlau yog qhia nyob rau hauv Kilograms rau ib 'meter' ntawm kev tsheb nqaj hlau. The rails used on Chinese railways include 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m.The cross-sectional shape of the rail adopts an I-shaped cross-section with the best bending resistance, consisting of three parts: the rail head, the rail waist and the rail bottom. Txhawm rau kom cov tsheb ciav hlau kom tiv thaiv zoo dua ntawm txhua sab thiab hauv qab tsim nyog muaj zog, lub taub hau yuav tsum muaj qhov chaw txaus, thiab qhov siab, thiab hauv qab yuav tsum tsis txhob nyias.

Taug qab hlau yog dav siv nyob rau hauv kev sib tw ntawm kev tsheb ciav hlau thiab kev thauj mus los. Ua ntej, nws yog siv rau kev tso cov tsheb nqaj hlau trackbeds. Cov ciav hlau thiab cov trackbed yog tsau los ntawm txheej tiv thaiv kom ntseeg tau tias qhov ruaj khov thiab kev nyab xeeb ntawm cov ntsia. Thib ob, nws yog siv rau kev kho tom qab taug kev tom qab taug kev khiav ntawm lub log ntawm txoj kev thiab txo kev ntxhov siab thiab kev puas tsuaj.
Cov kab hlau kuj tseem siv tau rau hauv kev tsim kho cov kab thauj khoom kom muaj kev ua haujlwm kom du ntawm cov ciav hlau thiab cov neeg caij tsheb. Tsis tas li ntawd, nws tseem yog siv dav hauv kev tsim kho cov chaw nres nkoj kom ntseeg tau tias kev thauj khoom nyab xeeb thiab thauj khoom thiab thauj khoom ntawm cov khoom.
