今天,只要打开广播或电视,来自世界各地的资讯尽在掌握,而传播音像的媒介就是广播卫星。吃饭时,那走上餐桌的绿色蔬菜、白色大米、红色肉类,也离不开天上的卫星。很多地区正是靠着卫星遥感的应用,为农田规划、粮食蔬菜生产做出科学安排。 Today, as long as you turn on radio or television, information from all over the world is at your fingertips, and the medium through which audio and video are transmitted is a broadcasting satellite. When eating, the green vegetables, white rice and red meat on the table can not be separated from the satellites in the sky. Many areas depend on the application of satellite remote sensing to make scientific arrangements for farmland planning and food and vegetable production.
