例句與造句

1. 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(wèn)題在于5 . 56毫米彈藥的殺傷性主要來(lái)自兩個(gè)方面：一個(gè)是命中后的翻滾（如同所有的尖頭槍彈） ，增加創(chuàng)腔的尺寸；另一個(gè)是它在翻滾的同時(shí)通常會(huì)破碎，碎片進(jìn)入體內(nèi)增加了傷勢(shì)的嚴(yán)重程度。
2. It's difficult to find pointed bullet in a sentence. 用pointed bullet造句挺難的
