本文以经典的大鼠血浆皮质酮（ＣＯＲＴ）为应激反应指标，根据实验数据，应用黑箱原理，建立了新的系统工作的数学模型，定量地分析了应激反应中心理性和躯体性因素各数量指标的相互作用。结果表明：（１）心理性与躯体性两种因素的正负协同方面，二者的复合效应是非线性的；（２）就两者的复合效应而言，不同的心理因素可减弱或加强应激反应，因此提出了存在质变分界点／域的可能性；（３）只有在适宜的躯体刺激强度范围内，心理因素才能发挥作用。
In this paper, the classic rat plasma corticosterone (CORT) as a stress response index, based on experimental data, the application of black box principle, the establishment of a new mathematical model of system work, quantitative analysis of stress response to the central and physical factors Interaction of quantitative indicators. The results show that: (1) the positive and negative synergistic effects between psychological and somatic factors are nonlinear; (2) the different psychological factors may be weakened or strengthened in terms of their combined effects Therefore, it is proposed that there is a possibility of qualitative change demarcation points / domains. (3) Psychological factors can play a role only in the range of appropriate body stimulation intensity.
