yog qhov sib npaug yog qhov xwm txheej ntawm qhov kev sib tw uas muaj kev sib tw sib npaug, ua rau tsis muaj qhov hloov pauv thaum sib npaug yog ib lub zog sib npaug, tab sis ntxeev ntawm, qhov tshwm sim sum ntawm vector zog; lub zog uas sib npaug rau lwm lub zog, yog li nqa ib qho khoom mus rau qhov sib npaug.
3 txoj cai yog dab tsi?
Yog peb lub zog tsis sib luag ua rau lub cev sib npaug, nws yog lub npe hu ua peb lub zog. … Yog li ntawd, cov kab kev ua ntawm tag nrho peb lub zog uas ua rau cov tswv cuab zoo li no yuav tsum sib tshuam ntawm ib qho chaw; ib leeg zog yog li ntawd sib npaug ntawm ob lub zog.
Lub zog twg nyob hauv qhov sib npaug?
Ib lub zog yog vector kom muaj nuj nqis uas txhais tau hais tias nws muaj ob qhov loj (loj) thiab kev taw qhia cuam tshuam nrog nws. Yog hais tias qhov loj thiab kev taw qhia ntawm lub zog ua rau ntawm ib yam khoom yog sib npaug, ces tsis muaj net quab yuam ua rau cov khoomthiab cov khoom tau hais tias nyob rau hauv equilibrium.
txhais li cas los ntawm qhov sib npaug?
