摘　　要：海蒂·拉玛是20世纪40年代的著名好莱坞影星,第一个全裸出镜的电影演员,曾被誉为世界上最美丽的女人。但是鲜为人知的是,她发明了跳频扩频无线电通信技术,并于1942年获得专利。这项技术由于各种各样的原因没有在二战中投入使用,但却在50年代被重新激活,最后成为今天在CDMA、WLAN、WiFi和蓝牙中广泛采用的通信技术。她的性感影星的身份在某种意义上影响了这项专利技术的及时应用和推广。海蒂·拉玛的遭遇折射了女性在科学技术发展史上的艰难地位。Hedy Lamarr was a famous Hollywood movie star in the 1940 s. She was the first actress who appeared naked on the screen and was once hailed as the most beautiful woman in the world. It is less well known, however, that she invented the "Frequency Hopping Spread Spectrum" technology and had it patented in 1942. For a variety of reasons, this technology was not put into practice during the period of the Second World War, but it was reactivated to use in the 1950 s and eventually became the widespread mode of communication in CDMA and WIFI. To some degree her identity as a sexy movie star affected the timely use and promotion of her invention. The plight of Lamarr reflects women’s difficult position in the history of science and technology.
