分析复合应激中心理性与躯体性两因素作用关系的数学模型探讨

A Mathemetical Model Analysing the Interaction between Psychological and Physical Factors during Stress

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。

The plasma corticosterone level was used as a criterion formagnitude of stress response in this experimental.According to principle of “black box”and the experimental data,a math.model was instituted and applied to analysis of interaction between psychological and physical factors in stress response.The results showed that 1)the interaction between psychological and physical factors in stress response was non-linear;2)stress response was enhanced or subsideed by different psychological factors;and 3)psychological factor played a role when physical stimulus intensity was within an appropriate rang.
