Based on this view, this paper analyzes the suitability of protective respirators to human body, and systematically puts forward such ergonomic problems as seal, respiratory resistance, dead space and field of vision about protective respirators at the angle of human facial features and bio-mechanical characteristics of head and neck.
笔者从人体的面部形态与生理机能角度,分析了呼吸防护用品与人体的适配性,系统提出密合性、呼吸阻力、死腔、视野等呼吸防护用品的人机工效学问题。
2.
Objective:To study the clinical significance of the respiratory resistance and diffusion capacity in lung cancer patients.
目的 :探讨脉冲振荡法 (IOS)对肺癌患者呼吸阻力和弥散功能的测定及临床意义。
3.
Eight subjects wearing five types of non-powered air-purifying respirators with different respiratory resistance and dead space were engaged in bicycle exercise test under medium(100W) and higher(155W) labor intensity,and the subjective well-being of subjects were recorded and analyzed.
测定了在中等(100W)和高等(155W)劳动强度下,8名受试者佩戴5种自吸过滤式呼吸器(呼吸阻力及死腔不同)从事踏车运动时的主观舒适度。
4) absorption resistance
吸附阻力
1.
The ability of caprock sealing free hydrocarbons includes two aspects:one is displacement pressure of the bottom caprock and other is absorption resistance of capillary for water in caprock.
盖层封闭游离相烃类的能力由两部分组成 ,一个是盖层底部岩石的排替压力 ,一个是盖层毛细管孔隙的吸附阻力 ,盖层毛管孔隙的吸附阻力与盖层岩性、成岩程度、厚度有关 ,盖层岩石的粒度越小、粘土矿物含量越高、成岩程度越强、厚度越大、盖层的吸附阻力越大 ,盖层的封闭能力越强。
5) resistance in breathing in O 2
吸氧阻力
6) acoustic resistance
吸音阻力
补充资料：溢流阀、顺序阀、减压阀的比较
溢流阀 | 减压阀 | 顺序阀 | ||
控制油路的特点 | 通过调整弹簧的压力控制进油路的压力，保证进口压力恒定，p2＝0 | 通过调整弹簧的压力控制出油口的压力，保证出口压力p2稳定 | 直控式－通过调定调压弹簧的压力控制进油路压力；夜控式－由单独油路控制压力 | |
出油口情况 | 出油口与油箱相连 | 出油口与减压回路相连 | 出油口与工作回路相连 | |
泄漏形式 | 内泄式 | 外泄式 | 内泄式 | |
进油口状态及压力值 | 常态 | 常闭（原始状态） | 常开（原始状态） | 常闭（原始状态） |
工作状态 | 进出油口相通，进油口压力为调整压力 | 进油口压力低于出油口压力，出油口压力稳定在调定值上 | 进出油口相通，进油口压力允许继续升高 | |
联接方式 | 并联 | 串联 | 实现顺序动作式串联作卸荷阀用时并联 | |
功用 | 定压、溢流或安全作用限压、稳压、保压 | 减压、稳压 | 不控制系统的压力，只利用系统的压力变化控制油路的通断 | |
进油腔压力p1控制阀芯移动 | 出油腔压力p2控制阀芯移动 | 进油腔压力p1控制阀芯移动 | ||
