Ntsiab
| 1 | Traverse center kab ntawm qhov txuas | l | yog ntau lub suab ntev |
| p | yog lub suab | dm | yog cov khoom siv txoj kab uas hla raws li ntsuas |
| ds | yog weld txoj kab uas hla | e | yog qhov ntev dimensionally cuam tshuam los ntawm vuam |
| w3 | yog qhov dav sab hauv ntawm qhov vuam | w2 | yog qhov dav sab nraud tshaj qhov vuam |
