天体神秘而奇妙,为探索其奥秘,天文学家和物理学家建立了一系列关于天体运动的理论,以此为素材的问题孕育而生。以下例析此类问题,让我们共同领略自然界的神奇魅力。 1 双星系统问题经过用天文望远镜长期观测,人们在宇宙中发现了许多双星系统,它们由两个星体构成,其中每个星的线度都远小于两星体之间的距离,一般双星系统距离其他星体很远,可以当作孤立系统处理。现根据对某一双星系统测定,知该系统中每个星体质量均为M,两者相距L,绕两者连线中心做圆周运动。
The celestial body is mysterious and wonderful. In order to explore its mysteries, astronomers and physicists have established a series of theories about celestial movements, which are born as material problems. The following examples analyze such issues, let us share the magic of nature. 1 Double-star system problems After long-term observation with astronomical telescopes, people have discovered many binary systems in the universe. They consist of two stars, each of which is much smaller than the distance between two stars. Generally, the binary system is away from other satellites. The star is far away and can be treated as an isolated system. According to the determination of a certain binary system, it is known that the mass of each star in the system is M, and the distance between the two is L, and a circular motion is performed around the center of the two connection lines.
