[背景了解]
　　文章取自于2004年1月的閱讀真題，是關于電子技術應用的文章，選段有點長，希望耐心看下，自己先猜下劃線部分單詞的意思吧
　　[文章部分]
　　"With virtual reality we'll be able to put a surgeon in every trench," said Satava. He envisaged a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers.
　　The computers would transmit images of the soldiers to surgeons back in the U.S. The surgeons would look at the soldier through virtual reality helmets (頭盔) that contain a small screen displaying the image of the wound. The doctors would guide robotic instruments in the battlefield mobile surgical unit that operate on the soldier.
