【摘要】：在日常生活中，80％的信息需要通过视觉获得，舒适的光环境对人的生活和工作都有非常重要的意义，有关光环境的研究也有了很大的进展。目前，国内外的研究大多数在常压环境的基础上开展，但在其他条件，例如低气压环境中，人体的生理反应（包括心率、血压、视力等）以及心理反应都会发生变化。因而导致人体感觉舒适的光环境与常压下可能存在差异，本文主要针对低气压下光环境对人体舒适感的影响开展研究，主要研究内容和成果如下：（1）低气压光环境影响人体舒适感的理论研究分别研究低压和光环境对人体舒适感影响的理论知识，得出低气压和光环境对人体的生理以及心理变化的影响，这部分是本文实验设计的理论依据。（2）低压下光环境对人体舒适感的实验研究首先进行了实验，研究在不同的压力、色温、照度对人体舒适感的影响程度。让受试者填写调查问卷，分布对9个主观感觉（明亮程度感觉、光的明暗比合适感觉、颜色真实性感、空间宽敞感、愉悦感、清晰感、放松感、紧张感、忧郁感）进行打分，并通过可拓学理论计算得出主观评价指标，得出结论：高色温（色温为6400K）让人在空间中更有明亮感、空间感、舒适感和愉悦感，，低色温（色温为3300K）下让人有放松感和忧郁感。不论何种色温，随着压力降低，受试者紧张程度增加，对视觉明亮程度感觉降低。（3）低压光环境下分析各评价指标以及生理指标通过分析调查问卷，分别得到9个主观评价指标与环境因素之间的关系，即不同压力、色温、照度对受试者心理感受的影响。对受试者进行血压、心率、视力测试，以及关于疲劳感的调查问卷，得出在本文实验条件下受试者的生理变化：受试者视力随压力降低、照度增加而升高；受试者心率均随压力降低而升高，血压则为无明显变化规律。
[Abstract]:In daily life, 80% of the information needs to be obtained through vision. The comfortable light environment is of great significance to people's life and work, and the research on the light environment has also made great progress. At present, most studies at home and abroad are carried out on the basis of atmospheric pressure environment, but in other conditions, such as low pressure environment, the body's physiological response (including heart rate, blood pressure, visual acuity, etc.) and psychological reaction will change. As a result, there may be differences between the light environment and the atmospheric pressure which lead to the comfortable environment of human body. This paper mainly focuses on the effect of light environment on human comfort under low pressure. The main research contents and results are as follows: (1) A theoretical study on the effect of low pressure light environment on human comfort The theoretical knowledge of the influence of low pressure and light environment on human comfort is studied, and the influence of low pressure and light environment on the physiological and psychological changes of human body is obtained. This part is the theoretical basis of the experiment design in this paper. (2) the experimental study on the comfort of human body in the light environment under low pressure The effect of different pressure, color temperature and illuminance on human comfort was studied. The subjects were asked to fill out a questionnaire to rate nine subjective sensations (brightness, light and shade than appropriate, color real and sexy, space spacious, pleasure, clarity, relaxation, tension, melancholy). The subjective evaluation index is calculated by extension theory, and the conclusion is that high color temperature (color temperature is 6400K) makes people feel bright, space, comfort and pleasure in space, and low color temperature (color temperature is 3300K) makes people feel relaxed and melancholy. No matter what color temperature, as the pressure decreased, the subjects increased tension and decreased visual brightness. Analysis of evaluation index and physiological index under low pressure light environment By analyzing the questionnaire, the relationships between 9 subjective evaluation indexes and environmental factors were obtained, that is, the influence of different pressure, color temperature and illuminance on the psychological feeling of the subjects. The blood pressure, heart rate, visual acuity test, and the questionnaire about fatigue feeling were used to find out the physiological changes of the subjects under the experimental conditions: the visual acuity of the subjects increased with the decrease of the pressure and the intensity of illumination; Heart rate increased with the decrease of pressure, but blood pressure did not change.
