Kev them nyiaj sai sai, rho tawm lub zog hluav taws xob, kev txhim kho cov kab ke ntawm lub zog hluav taws xob ntawm lub zog hluav taws xob hauv lub zog hluav taws xob, txhim kho cov hluav taws xob ib puag ncig. Yog li reactive fais fab nyiaj pab kiag li yog nyob rau hauv ib qho tsis tseem ceeb thiab txoj haujlwm tseem ceeb hauv lub zog hluav taws xob. Cov kev xaiv tsim nyog ntawm them nyiaj tuaj yeem ua tiav qhov kev txo qis tshaj plaws ntawm lub hwj huam poob thiab txhim kho lub zog ntawm lub zog. Ntawm qhov tsis sib xws, xaiv tsis raug cai lossis siv yuav ua rau cov khoom poob tseem ceeb, thiab cuam tshuam cov khoom siv hluav taws xob hauv lub zog hluav taws xob. Lub ntsiab cai tseem ceeb ntawm kev them nyiaj fais fab: Lub zog tawm ntawm lub zog hluav taws xob, siv hluav taws xob, siv hluav taws xob, thiab siv lub zog ua haujlwm. Qhov no feem ntawm lub zog yog hu ua lub zog nquag; Rease Fais Fab: nws tsis haus lub zog hluav taws xob, tab sis tsuas yog hloov nws mus rau lwm hom kev. Lub zog no yog qhov tsim nyog siv rau cov khoom siv hluav taws xob los ua haujlwm, thiab nws yog siv hluav taws xob nrog hluav taws xob hauv lub hwj chim. Feem ntau ntawm cov hwj chim yog hu ua cov hluav taws xob muaj zog los ntawm cov chaw sib nqus, thiab hluav taws xob muaj zog los ntawm kev tsim hluav taws xob tsim kom muaj hluav taws xob teb).
Kev siv cov txheej txheem ntawm kev rov them hluav taws xob: Txuas lub cuab yeej nrog lub zog hluav taws xob thauj khoom hauv tib lub zog, thiab sib pauv zog nruab nrab ntawm ob lub nra. Nyob rau hauv txoj kev no, cov hluav taws xob reactive yuav tsum tau los ntawm inductive thauj khoom tuaj yeem them los ntawm cov hluav taws xob tawm hluav taws xob tawm los ntawm kev thauj khoom.
