Thawj khub ntawm kev ua - cov tshuaj tiv thaiv quab yuam khub yog: ko taw A thawb pob B mus rau sab xis; thiab pob B thawb ko taw A mus rau sab laug.
Ua raws li qhov no, koj yuav txheeb xyuas qhov kev txiav txim thiab kev tawm tsam li cas?
Qhov loj ntawm lub zog ntawm thawj yam khoom sib npaug ntawm qhov loj ntawm qhov zog ntawm qhov khoom thib ob. Kev taw qhia ntawm lub zog ntawm thawj cov khoom yog opposite rau cov kev taw qhia ntawm lub zog ntawm qhov khoom thib ob. Kev quab yuam ib txwm tuaj ua khub uas sib npaug thiab sib npaug. Cov no yog hu ua kev ua - tshuaj tiv thaiv quab yuam khub.
Tsis tas li ntawd, qhov piv txwv ntawm kev ua thiab kev tawm tsam yog dab tsi? Cov kev txiav txim thiab cov tshuaj tiv thaiv lub zog yog reciprocal (tawm tsam) ntawm ib qho khoom.

Dab tsi yog qhov kev ua yeeb yam ua khub?
Lub zog ntawm lub ntiajteb txawj nqus, thiab lub zog ib txwm muaj, yog tsis yog ib qho kev ua yeeb yam khub . Thaum xub thawj siab ib muag nws yuav tshwm sim hais tias cov no yog kev ua - cov tshuaj tiv thaiv khub vim lub zog sib npaug thiab sib npaug.
