本文阐述了各类人群在自然界信息刺激下的不同心理反应过程以及人体肌群在受控于脑部不同信息强度控制时产生的力学渐变状态。不同的人群,对突发事件的心理承受力也存在较大的差别。我们可用数学公式进行详细的叙述其内在的含义。另外,关于人体肌群在脑部不同强度意识的控制下可形成肌群收缩力的量变过程,然而对于这种肌群的收缩力变化我们仍然可用数学公式加以描述。 This article describes the different psychological processes stimulated by nature information in various kinds of people and the mechanical gradation of the human muscle group controlled by different information intensity in the brain. Different people, there is a big difference in psychological endurance of emergencies. We can use mathematical formulas to describe in detail its inherent meaning. In addition, the body muscle group in the brain under different levels of consciousness can control the formation of muscle contraction force of the quantitative process, but for this group of muscle contraction force changes we can still be described by mathematical formulas.
