天体物理和空间技术作为现代高科技领域的前沿,有着取之不尽的素材,因而题型也是相当多的,下面列举其中几类。1 论证题例1 某小报登载:×年×月×日,×国发射了一颗质量100千克,……,周期为1小时的人造环月卫星,一位同学记不住引力恒量G的值,且手边没有可查找的资料,但他记得月球半径约为地球的1/4,月球表面重力加速度约为地球的1/6,经过推理,他认为该报道是则假新闻,试写出他的论证方案(地球的半径约为6.4×103千米)
Astrophysics and space technology, as the frontiers of modern high-tech fields, have inexhaustible material. Therefore, the questions are quite numerous. Here are some of them. 1 Case 1 of the argumentation was published in a tabloid newspaper: ××year×month×day, × country launched a satellite with a mass of 100 kg,..., and the period was 1 hour. One classmate could not remember the value of gravitational constant G. , And there is no information available at hand, but he remembers that the radius of the moon is about 1/4 of the earth, and the gravitational acceleration of the moon’s surface is about 1/6 of the earth. After reasoning, he thinks the report is false news. Try to write him out. The demonstration program (the radius of the earth is approximately 6.4×103 km)
