Kev txhais ntawm kev siv tshuab yoj
Kev nthuav tawm ntawm cov neeg kho tshuab kev co hauv nruab nrab yog hu ua kev siv tshuab yoj. Cov hlau tsis muaj zog thiab lub tshuab xaim hluav taws xob muaj qhov sib xws thiab sib txawv. Cov vuam tshuab txhua qhov yog tsim los ntawm kev siv tshuab, thiab hluav taws xob tsis muaj hluav taws xob yog tsim los ntawm electromagnetic oscillations. Cov lus tshaj tawm ntawm cov khoom siv tshuab yuav tsum muaj qhov nruab nrab tshwj xeeb. Kev tshaj tawm ceev hauv xov xwm sib txawv kuj sib txawv, thiab nws tsis tuaj yeem xa mus hauv lub tshuab nqus tsev txhua lub sijhawm. Cov ntsuas hluav taws xob (xws li lub teeb ntoj hluav taws xob) tuaj yeem tawm suab hauv lub tshuab nqus tsev; cov neeg kho tshuab yoj tuaj yeem tuaj yeem shear vuag thiab kav ntev, tab sis cov khoom siv hluav taws xob tsis tuaj yeem tsuas yog shear vuam; ntau lub cev lub zog ntawm cov khoom siv thev naus laus zis thiab cov xov hluav taws xob, xws li kev tig rov qab thiab xav txog, yog xwm yeem, thiab cov khoom siv hauv lub cev uas piav qhia lawv kuj zoo ib yam. Cov vuag ib vuag hlau ib txwm muaj: dej nthwv dej, ntu nthwv dej, thiab nthwv dej hiav txwv.
