在世界上,最初的核试验,多在铁塔上爆炸。因这种地面爆炸,会卷起很多放射性尘埃,经过高空气流散布到世界各地,遭到众多的反对。而空中爆炸,试验者可根据所试核弹当量的大小,确定爆炸的高度,保证地面尘埃不致和核爆炸后产生的放射性烟云一起卷入高空,对地球污染和遭受的反对都要少些,所以美、苏、法、英逐渐使用空爆的方式。随后,又逐渐采用地下试验方式。我国核试验起步晚,由于种种原因还不 In the world, the first nuclear tests were mostly explosions on the towers. Because of such an explosion on the ground, many radioactive dusts are rolled up and are subject to numerous objections after being scattered through the high air currents all over the world. In the air explosion, the experimenter can determine the height of the explosion according to the size of the nuclear bomb tested so as to ensure that the dust on the ground does not become entangled in the sky with the radioactive cloud of smoke generated after the nuclear explosion. Therefore, there are fewer objections to the earth’s pollution and suffering The United States, the Soviet Union, France, Britain gradually use the method of air burst. Subsequently, and gradually using underground test methods. Our nuclear test started late, due to various reasons
