摘　　要：在同样房间换气次数下,改变送风速度和出风面积,对OR.B手术室进行了数值模拟以比较在手术关键区(围绕患者手术切口的三个相连区域)的细菌沉降数量。结果表明改进气流流型可以降低关键区域的微粒沉降量,但效果并不如增加换气次数至某个恰当量那么明显。When changes the supply air velocity and discharge area in the OR.B numerical model under same room air change rate, to compare bacteria colony deposition onto the ＂critical area＂, which consisted of three connected areas around the surgical site on patient body, result showed that improving air flow pattern can reduce particle deposition on critical surface, but its effect is not as obvious as yield to that increasing the air change rate in a certain amount.

关 键 词：医院手术室 颗粒 CFD 换气次数
