Passage 2Donegal is located in the windswept wilderness. It might seem an odd place to find one of Europe’s most dynamic companies. But a small assembly unit making a muscular stimulation product for leisure and healthcare is blazing a trail. BMR Teoranta—the company title in Irish—has quietly established a market for itself, making products for muscular therapy and body toning using the brand name Slendertone which it bought in 1989.Mr. Kevin McDonnell, the chairman, chief executive and owner of 95 per cent of the company, is a little vague about the source of his success. Part of it, he says, must be the p work ethic in the area. He points out that half his employees are from Galswegian families with their Scottish attitudes of thrift and industry. Mr. McDonnell bought the company for $300,000 and BMR sales are now growing at around 50-60 per cent a year.The medical products business, where growth is less dramatic, but margins are attractive, is seen as the source of the company’s future earnings. In the US alone, the market for muscular stimulation products has jumped from $88m to more than $200m this year.Many BMR products are not available over the counter but through catalogues. The company is looking at special advertising on video shopping channels. In the US companies like BMR are prohibited from selling medical products over the counter. In Europe this situation is slightly different. BMR, for example, is starting to sell its consumer range in Carrefour superstores in France and its range is available in pharmacies. However, under a European Union ruling similar to US laws, companies that sell such products will have to reequip their factories to meet new health standards. “I know it sounds a bit smart, but our products have always been seen as industry standard,” says Mr. Kevin McDonnell.The company spends £1,000,000 a year on research and development, quite a large sum for a company of its size.

The brand name of this product for muscular therapy is BMR Teoranta in Irish. ( )

问答题

汽车在行驶过程中如果遇到危急情况,司机常要紧急刹车.从发现情况到汽车停止的距离叫做停车距离,停车距离等于反应距离加上制动距离.(注:反应距离是指司机发现情况到踩下刹车这段时间内汽车们行驶距离;制动距离是指踩下刹车后汽车在路面上滑行的距离)。

下表是司机驾驶小汽车时,在水平、干燥的沥青路面上以不同速度行驶时的统计数据。

(1)请利用表中数据,在如图所示的坐标图中用平滑曲线绘出制动距离随速度变化的曲线。(请先用铅笔,确定后再用标准答题笔涂黑)

(2)一起发生在限速50千米/时路段的交通事故中.交警测得肇事车后留下的刹车痕迹(制动距寓)长为25米.请你根据上面图象判断司机是否超速?________ 。(注:该车的制动性能与上表数据一致)

(3)反应距离取决于反应时间和行驶速度。下列行为不会使司机反应时间变长的是( )。

A.疲劳驾驶

B.酒后驾驶

C.打手机

D.超速驾驶(4)轮胎长期能用后会变光滑,则在相同情况下,制动距离会变      

(5)在图中,图A是在高速公路上用超声测速仪测量车速的示意图,测速仪发出并接收超声波脉冲信号。根据发出和接收到的信号间的时间差,测出被测物体的速度,在图B中,P1、P2是测速仪发出的超声波信号,n1、n2分别是P1、P2由汽车反射回来的信号,设测速仪匀速扫描,P1、P2之间的时间间隔△t=1.0s,超声波在空气中传播的速度v=340m/s,若汽车是匀速行驶的,则根据图中可知,汽车在接收到P1、P2两个信号之间的时间内前进的距离是_________m,汽车的速度是________m/s。
