And the lower section of the component is immersed in the tr y froth for reducing tr y forth height nd froth pe k, with the higher section in the diseng gement sp ce bove tr y froth for diminishing entr inment. The experiment l results indic ted th t the structur l component w s ble to diminish entr inment by 61% ~ 76% , reducing steep froth pe k on tr y froth surf ce for the fo ming system, nd could ddition lly decre se the tr y forth height by 15. 2% ~ 17. 1% for the nonfo ming system.Therefore, the new tr y c n defo m effectively, del ying flood of tr y forth nd of excessive entr inment. Key words: tr y; structur l component for mech nic l defo ming; fo ming system; entr inment , , , [5] 250Y [ 1] , , , , , [ 2] , ,
