Kub xovxwm loading thiab pwm loading

Cov txheej txheem ntawm kev ntxiv cov khoom molding xav tau rau cov khoom rau pwm yog hu ua them, thiab tus nqi them yog txiav txim siab tom qab kev ntsuas siab raws li qhov ntsuas tau. Kev txhim kho pwm yuav tsum ua raws li cov hauv qab no: cov khoom siv luv tshaj plaws: cov khoom yuav tsum tau muab tso sib npaug; rau qhov nqaim khiav thiab cov ces kaum tuag, cov khoom yuav tsum tau muab tso ua ntej.
