Qhov roughness ntawm cov khoom siv roj hmab hais txog qhov tsis sib xws ntawm qhov chaw, feem ntau qhia los ntawm Ra (qhov nruab nrab roughness). Lub roughness ntawm cov khoom siv roj hmab yuav cuam tshuam rau nws cov tsos, kev ua tau zoo thiab kev pabcuam lub neej.

Qhov saum npoo roughness ntawm cov khoom siv roj hmab muaj kev cuam tshuam rau kev sib khi, kev sib txhuam kev ua haujlwm, hnav tsis kam thiab zoo li zoo. Cov hauv qab no yog cov kev cuam tshuam tshwj xeeb:

1. Sealing kev ua tau zoo: qhov me me ntawm qhov roughness ntawm cov khoom siv roj hmab, qhov loj dua qhov chaw sib cuag ntawm cov khoom siv roj hmab thiab cov sealing nto, thiab qhov kev sib khi zoo dua. Hloov pauv, qhov ntau dua qhov roughness ntawm qhov chaw, qhov me me ntawm qhov chaw sib cuag thiab qhov ua tau zoo ntawm kev sib khi.

2. Kev sib txhuam kev ua haujlwm: Qhov roughness ntawm cov khoom siv roj hmab muaj kev cuam tshuam rau kev sib txhuam kev ua haujlwm. Qhov me me ntawm qhov roughness, qhov me me qhov coefficient ntawm kev sib txhuam, thiab vice versa. Yog li ntawd, nyob rau qee lub sijhawm uas kev sib txhuam yuav tsum tau txo, nws yog ib qho tsim nyog yuav tau xaiv cov khoom siv roj hmab nrog me me roughness.

3. Hnav tsis kam: Qhov roughness ntawm cov khoom siv roj hmab kuj cuam tshuam rau kev hnav tsis kam. Qhov me me ntawm qhov roughness, qhov zoo dua qhov hnav tsis kam ntawm cov khoom siv roj hmab, thiab rov ua dua. Yog li ntawd, nyob rau qee lub sijhawm uas xav tau kev hnav zoo dua, nws yog qhov yuav tsum tau xaiv cov khoom siv roj hmab nrog me me roughness.

4. Cov tsos mob zoo: Cov khoom siv roj hmab uas muaj qhov ntxhib saum npoo tuaj yeem muaj teeb meem xws li cov khaub ncaws, qhov tsis sib xws, kev puas tsuaj, bulge, tawg ntawm cov kab sib cais, cov nti dawb, thiab cov xim pleev xim, uas yuav cuam tshuam rau nws txoj kev zoo nkauj thiab zoo. Qhov me me ntawm qhov roughness, qhov zoo dua qhov zoo ntawm cov khoom siv roj hmab, thiab lwm yam. Yog li ntawd, nyob rau qee lub sijhawm uas yuav tsum tau ua kom zoo zoo, nws yog ib qho tsim nyog los xaiv cov khoom siv roj hmab nrog me me roughness.

Txhawm rau ua kom tiav, qhov roughness ntawm cov khoom siv roj hmab muaj qhov cuam tshuam tseem ceeb ntawm kev ua haujlwm thiab cov tsos, thiab nws yuav tsum tau xaiv qhov tsim nyog roughness raws li kev siv tiag tiag.
