General Paul Selva , deputy chairman of the joint chiefs of staff , saidthere needed to be a " firebreak " between a machine that can assess massive quantities of data tomake a targeting decision and one that decided on the use of force .

美国参谋长联席会议副主席保罗•塞尔瓦将军（GeneralPaulSelva）表示，需要在一台能够评估海量数据以决定打击目标的机器与决定使用武力的机器之间树立一道“防火屏障”。

The results showed that the minimal relative wind speed in the windward area of firebreak tree belt with a sparse and tight structure was down to 70 % below , but in the windward area of the ventilate structure was only down to about 80 % .

结果表明：紧密结构与疏透结构的防火林带迎风面的阻风性能比较好，最小相对风速达到70%以下，而通风结构的阻风性能最小，迎风面的最小相对风速在80%左右。
