摘要: 在本工作中,呼吸阻力感觉被看作是一种模糊量。采用模糊集的途径揭示了这一模糊量的可能性分布。在此基础上,建立了用来估定呼吸阻力负荷的感觉量公式 F~k(u_i)=(1/t)(sum from j=1 to m (V_jy_(ij)~kw_j/sum from j=1 to m (y_(ij)~kw_j)。通过对37名被试在不同负荷时相下各种外加阻力负荷所致的感觉进行测试,揭示了如下一些基本事实:呼吸阻力负荷与其感觉间的心理物理函数遵循幂定律;三种呼吸阻力时相下的呼吸阻力感觉体验有显著差异,但是统计检验表明它们的感觉增长速度差异不显著;本实验还找出了与各感觉类别等级相应的阻力负荷值,可供制订防护装置阻力标准参考;最后还比较与讨论了有关的方法学问题。

Abstract: Psychological magnitude associated with respiratory resistive loadis considered as a fuzzy one in this study. A fuzzy set approach calledMultistage Evaluation Scale (MES) was adopted to reveal a possibilitydistribution of this fuzzy magnitude, and a formula for treatment of thedata-- --was used to estimate psychological.magnitude associated with respiratory resistive load. Thirty--seven.healthy young male subjects experienced six levels of suprathresholdadded resistance, loaded at different phases of the breathing cycle. The results revealed that the relationship between resistive load. and perceived magnitude can be expressed by psychophysical powerfunction. The data showed that the severity of the sensory experiencecaused by equal resistive intensity differed significantly when loaded atdifferent phases of the breathing cycle, but the speed of sensory growthdid not manifest significant change. The experiment also showed thatthe physical and physiological magnitudes were correlated to eachsensory category grade of the scale, which may be useful for establishingresistive standards for respiratory protective equipments. We also com-pared and discussed methodology related to MES and classicalcategory scale.
