无线扩频技术最初是由美国军方开发研制的,具有极高的保密性和抗衰落性,其原理是把常规的无线传输频段扩展几倍至几十倍。1993年,扩频通信开始在美国市场上销售使用,1994年介绍到中国,广泛应用于电力、证券、石油、银行、海关等领域,水利防洪调度中也开始使用。扩频通信的主要产品为美国 CYLINK 公司生产的无线扩频设备。该设备为智能型,不
Wireless Spread Spectrum technology was originally developed by the U.S. military to develop with high confidentiality and anti-fading, the principle is to extend the conventional wireless transmission frequency several times to several times. In 1993, spread spectrum communication began to be used in the American market. In 1994, it was introduced to China and widely used in electric power, securities, petroleum, bank, customs and other fields. Flood control dispatching also started to be used. The main products of the spread spectrum communication are the wireless frequency spreading devices produced by the United States CYLINK Company. The device is smart, no

提起加拿大的当代艺术，查莱斯·帕切特（Charles Pachter，1942-）的油画自然是其中不可或缺的组成部分。帕切特似乎是以一种庄严的姿态在充满怀疑论色彩的加拿大艺术世界里寻求并标定出自我领域的艺术家，他的那些绘画创作可以看作是对加拿大本土艺术符号的持续探索，从而成为对加拿大民族文化及精神品质的泰然自若的肯定和赞美，这无疑对加拿大的公众文化产生了巨大的影响。
