36 Daim EOD Cov Cuab Yeej Tsis Muaj Hlau Sib Nqus
Cov cuab yeej siv tsis muaj hlau nplaum feem ntau siv beryllium bronze ua cov khoom tseem ceeb, thiab yog cov khoom lag luam hauv tebchaws IIC. Nws ua haujlwm hauv qhov concentration ntawm 21% hydrogen thiab tsis ua rau cov roj tawg. Vim tias qhov magnetism ntawm cov khoom siv beryllium bronze yog xoom, cov cuab yeej beryllium bronze kuj hu ua cov cuab yeej tsis muaj hlau nplaum, uas tuaj yeem nyob hauv thaj chaw magnetic. Kev ua haujlwm zoo rau ib puag ncig. Thaum cov neeg ua haujlwm tawg pov tseg cov khoom, cov cuab yeej tuaj yeem tiv thaiv cov hluav taws xob tsim los ntawm...
