We introduced a computer program developed for numerical analysis of thermal conditions of all segments and blood circulatory systems in the human body to precisely evaluate human thermal physiological and psychological responses. In this program, a cylindrical model consisting of internal multi-layers is adapted for the segment of the human body. For the multi-layered concentric cylindrical model, we adopted a new numerical solution method. By using this computer program, the internal tissue temperatures, heat fluxes and blood temperatures of all segments in the human body could be calculated simultaneously. This program also included a subroutine for calculation of thermoregulatory response. In addition the program was installed a subroutine for prediction of thermal psychological responses with neural network technique.This report describes the improvements made to this computer program for simulating individual physical differences and its application to various working levels. The main points for improvement were the assigning procedures of physical characteristics of individuals and local muscle heat production. The improved computer program was used to simulate the whole body temperatures of subjects during various kinds of exercise under various thermal environmental conditions. The calculated results were well agreed with the measured results. It was indicated that improvement of a prediction computer program of whole body temperature was effective.

本文介绍了一种计算机程序，它可以对人体各部位和血液循环系统的热状况进行数值分析，以精确地评估人体的热生理和心理反应。在这个程序中，一个由内部多层组成的圆柱形模型适用于人体的部分。对于多层同心圆柱模型，采用了一种新的数值求解方法。利用该程序可以同时计算出人体各节段的组织温度、热流和血液温度。该程序还包括计算体温调节反应的子程序。此外，还在程序中加入了神经网络技术预测热心理反应的子程序，本文介绍了对这一模拟个体生理差异的计算机程序所作的改进及其在不同工作水平上的应用。改进的重点是个体物理特征和局部肌肉产热的赋值程序。用改进后的计算机程序模拟了受试者在各种热环境条件下进行各种运动时的全身温度。计算结果与实测结果吻合较好。结果表明，改进的全体温预测程序是有效的。
