局部惯性系的优越性

THE SUPERIORITY OF LOCAL INERTIAL FRAME

对于任意一个计算系统，在一般情况下，“时—空”是不均匀的，空间也不是各向同性的，因而应在黎曼空间中去描述这一弯曲的“时—空”特性．即在自然界中，由于引力的不可屏蔽性，因而在有引力存在的“时—空”中去研究物质的运动规律时，应在黎曼空间中去描述．本文采用“消除”外力的局部惯性系（文中称ｇ坐标系）来进行观测．这样，将一个“非均匀时空”的黎曼空间，转换为一个“均匀时空”的“平直”的闵可夫斯基空间．“消除”了引力场的作用，从动力学中的加速效应和“静力学”中的形变效应两个方面都得到了满意的结果。

Generally speaking, in any calculating system, the “space time” is not even and the space is not of the same nature in any direction. Therefore, the property of the zigzag “space time” should be described in the Riemann space. In the natural world, gravitation cannot be shielded. When the law of the motion of matter is studied in the “space time” with the presence of gravitation, it should be described in the Riemann space. This paper tries to conduct the observation by using the local inertial frame (in this paper, g frame of axes) with gravitation eliminated. In this way a Riemann space with uneven “space time” can be changed into an Minkowski space which is even and straight and with the even “space time”. Since the effect of gravitation field has been eliminated, the result of observation is satisfactory (ideal) from both the accelerating effect of dynamics and the deformation effect of statics. This fully shows the superiority in the study of local inertial frame.
