    Sandstorms (沙尘暴) happen suddenly and have effects on large areas. One example was a sandstorm on the Western  Route. It  moved  quickly  southward (向南 ) from May 4th to 6th,1993,having effects on a total area of l.1 million sq km,from northern Xinjiang to the Hexi area of Gansu,western Inner Mongolia and most of the Ningxia Hui Autonomous Region. The wind speed reached 37. 9  m/s, and the visibility (可见度) was less than 50m. In Xinjiang,Gansu,Inner Mongolia and Ningx-ia,85 persons died and 264 were injured;4,412 houses were damaged,and 120,000 animals died or went missing. The direct economic  losses (直接的经济) were about 550 million yuan,which further damaged the environment and economic development. Another example was the sandstorm which happened from April 16th to 18th,1998. Blowing from west to east,it even reached the lower reaches of the Yangtze River. This never happened  in hisl.ory. A sandstorm meeting rain over Beijing formed " muddy(多泥的 ) rain" there. Floating dust  troubled  the Inner Mongolia Autonomous Region, Beijing, Ji'nan of Shandong Province and Nanjing.

1946年2月15日，第一台电子计算机ENIAC在美国宾夕法尼亚大学诞生了。它是为计算弹道和射击表而设计的，主要元件是电子管，每秒钟能完成5000次加法、300多次乘法运算，比当时最快的计算工具快300倍。该机器使用了1500个继电器，18800个电子管占地170平方米，重30多吨，耗电150千瓦，耗资40万美元，真可谓“庞然大物”。用ENIAC计算题目时，首先，工作人员要根据题目的计算步骤预先编好一条条指令。
