tumbling body 中文意思是什麼
tumbling body
解釋
回轉體-
The problems occur because the 5. 56 mm bullet gains much of its lethality from two features : one is that ( like all pointed bullets ) it tumbles on impact, increasing the size of the wound channel ; the other is that it often breaks up while tumbling, sending fragments through the body and increasing the severity of the wound
問題在於5 . 56毫米彈藥的殺傷性主要來自兩個方面：一個是命中后的翻滾（如同所有的尖頭槍彈） ，增加創腔的尺寸；另一個是它在翻滾的同時通常會破碎，碎片進入體內增加了傷勢的嚴重程度。
