南非世界杯的“足球”比普通足球更圆?

会计考友

Players in the World Cup soccer tournament, now underway in South Africa, will have to contend with low oxygen levels at high altitude--and with a new ball, which its scientist creators say is the roundest one ever.   　　With the World Cup soccer tournament underway in South Africa, a couple of things for the science-interested audience to watch for. First, the games will feature a new ball, called the Jabulani, the Zulu word for "celebrate." And some players think something foul is afoot. They contend that the ball doesn't behave the way a normal soccer ball should, that it even turns the wrong way in mid-air. Adidas, which makes the ball, claims that the players complaining all have contracts with Adidas's competitors.
　　The Sports Technology Research Group at England's Loughborough University designed the ball. The sections aren't stitched together anymore. Instead, the seams are glued or heat-sealed. The group leader, Andy Harland, told the Telegraph newspaper, "We have created a ball that is almost perfectly round, and more accurate than ever before." Well, millions of soccer fans will ultimately decide the latter.
　　Also watch for the effects of altitude. Some of the games in South Africa will be played at elevations over a mile high. Which could make catching one's breath the primary goal.

　　另外，球迷们还可以关注海拔因素对比赛的影响。部分比赛将在海拔超过一英里的地区举行，解决呼吸困难问题将成为球员们的首要任务。
