Khoom ntawm siab transmitter
Cov khoom siv piezoelectric feem ntau yog siv hauv kev hloov pauv siab yog quartz, dihydrogen phosphate thiab potassium sodium tartrate. Quartz, nws yog ntuj siv lead ua. Tsis pub dhau qhov ntsuas kub ib puag ncig, cov khoom siv piezoelectric ib txwm muaj, tab sis tom qab qhov kub siab tshaj qhov ntsuas no, cov khoom piezoelectric ploj tag, thiab cov txiaj ntsig piezoelectric pom nyob hauv cov siv lead ua no. Dihydrogen phosphate yog cov khoom siv dag uas tuaj yeem tiv taus qhov kub thiab txias heev, yog li nws tau siv dav. Potassium sodium tartrate muaj qhov zoo heev piezoelectric rhiab heev thiab piezoelectric coefficient, tab sis nws tsuas yog siv tau hauv ib puag ncig uas qhov kub thiab txias hauv chav nyob tsawg.
