长期以来,我们防御洪水的措施,无非是修建水库拦蓄洪水,加高堤防、疏浚河道以渲泄洪水。这种方法虽然有效,却只是被动地接受天空降雨,需要强大的经济力量,但仍不能免除洪水威胁。随着现代科学技术特别是航空航天等高科技的发展,人们逐步揭示了风云雷电的秘密,并掌握了一些规律。我们已能够测定积雨云的厚度、降水量以及发展规律等。这些将使防御洪水的高技术措施成为可能。高技术措施的设想暴雨或特大暴雨是造成洪灾的主要原因。设想通过采用一系列高技术措施,减弱暴雨强度,使降雨提前或推迟、扩大或减少降雨笼罩面
For a long time now, our measures to prevent floods have been to build reservoirs to flood control, raise embankments and dredge channels to release floodwater. Although effective, this method only accepts the rainfall of the sky passively and requires strong economic power, but it still can not avoid the flood threat. With the development of modern science and technology, especially aerospace and other high-tech, people gradually revealed the secrets of the Storm Lightning and mastered some laws. We have been able to determine the thickness of thunderstorm, precipitation and the law of development. These will make high-tech defenses against flood possible. Hypothetical high-tech measures Heavy rain or torrential rain is the main cause of flooding. It is envisaged that by adopting a series of high-tech measures to weaken the intensity of rainstorms, to allow rainfall to advance or postpone, to increase or decrease the rainfall overrun
