The Jet Balloons will be used for the first time in Holland. They are special balloons, equipped with a valve. They should be inflated five minutes before the players enter the pitch, so that the entire stadium will be an ocean of red-white colours. The moment the referee leads players unto the pitch, the balloons should be released. They go straight up due to the valve and produce a great sound. If over 30, 000 spectators do so at the same time, the effect could be very special indeed!

这些气球的使用，在荷兰应该是第一次，它们都是一些特殊的气球，它们将在球员们进场前在体育场上空飘荡大约5分钟，所以，体育场在这段时间将会是一个红、白色的海洋，而等到这些球员都进场后，这些气球就会被释放，同一时间，它们将伴随着巨大的响声向上飘起，它们的数目可能超过3万多个，到时候景象会是非常壮观的！

Since the 1990s, the United States has used force overseas on more than 40 occasions. On April 1, 2001, a US military reconnaissance plane flew above waters off China's coast in violation of flight rules, causing the crash of a Chinese aircraft and the death of its pilot. It presumptuously entered China's territorial airspace without permission from the Chinese side and landed on a Chinese military airfield, seriously encroaching upon China's sovereignty and human rights.

仅20世纪90年代以来，美国对外使用武力就达40多次。2001年4月1日，美国军用侦察机在中国近海上空违规飞行，造成中国飞机机毁人亡，且未经中方允许，擅自进入中国领空，降落中方军用机场上，严重侵犯中国主权和人权。

Want to decide the azimuth of a mobile phone has two kinds of methods normally: The first kind of method is the GPS chip that the mobile phone uses, pass the satellitic network that in the sky covers the world and wireless communication to identify the trend with located mobile phone; The 2nd kind of method is three angular distance calculate a standard, mobile phone to around base the station issues signal, differ through calculating signal to arrive at base the time of the station will determine the mobile phone is located azimuth.

要确定一部手机的方位通常有两种方法：第一种方法是手机使用的GPS芯片，通过覆盖地球上空的卫星网络和无线通信来识别手机所处的方位；第二种方法是三角距离测算法，手机向四周的基站发出信号，通过测算信号抵达不同基站的时间来测定手机所处方位。
