反思地月之间的约束机制

Rethinking the restraint mechanism between the Earth and Moon

摘要: 月球总是以同一个面朝向地球，而解释这种现象的主流理论存在一个死角，即无法解释月球为什么没有以地月质心之间相连的直线为轴而自转。因为月面上众多的陨石撞击坑表明，它完全有可能获得动量，并以此为轴而自转。本文提出一个朴素的解释，那就是地月之间的万有引力，以及地球的磁场，对月球形成了一个三位一体的约束机制。依据这一解释，月球的自转可以被锁定，并且月球天平动的机理也被揭示出来，它还可以与这种月球在摇摆中寻求平衡的自然现象相互印证。此外，借助阿波罗登月和其它航天器环月飞行等各类探测数据，以及对月壤样品的研究分析，结论是：就月球整体而言，属于顺磁类的物质，它的相对磁导率在1.008和1.03之间；尽管由于太阳风的影响，地球磁场在月球轨道上的磁感应强度已经降低到6.5×10^-5 nT以下，但它可以成为锁定月球不以地月质心之间的连线为轴而自转的理由。如果无法找到另一个导致这一事实存在的主要原因，地球磁场在月球轨道上的磁感应强度即使再小，也不应该轻易忽略。对此，我们可以人为地改变地球磁场的强度，并仔细观察月球天平动和地月之间距离的变化，以验证本文的论点。

Abstract: The Moon is always with the same face toward the Earth. However, the prevailing theory to explain this phenomenon, there is a dead angle. That is why the Moon does not rotate around the axis which is a straight line between the Earth and Moon to connect to their mass centers. Because many of meteorite impact craters on the lunar surface have indicated that the Moon was entirely possible to obtain momentums to rotate around the axis. In this paper, we propose a plain explanation which is the universal gravitation between the Earth and Moon as well as the Earth's magnetic field to have formed a trinity restraint mechanism about the Moon to be locked. According to this explanation, the Moon's rotation can be locked, the mechanism of lunar libration has been revealed out, which can confirm mutually with the natural phenomenon that the Moon seek a balance in the swing. In addition, with the help of all kinds of detection data from the Apollo moon landings and other circumlunar spacecraft to detect, as well as the studies of lunar soil samples, the conclusion is that as a whole for the Moon, which belongs to the paramagnetic substance, its relative permeability is between 1.008 and 1.03. Although the magnetic flux density of the Earth on the lunar orbit has been dropped below 6.5×10^-5 nT due to the influence of the solar wind, but it can become a reason to lock onto the moon and not rotate around the axis that is a straight line between the Earth and Moon to connect their mass centers. If you cannot find another main reason which can cause the existence of this fact, for the Earth's magnetic field on the lunar orbit, even if the magnetic flux density is very small, also shouldn't be easily ignored. In this regard, we can artificially change the intensity of the Earth's magnetic field, and carefully observe the changes in the lunar libration and in distance between the earth and the moon, to verify the arguments in this paper.
