【摘要】 目的本试验研究当电梯以额定速度1.75m/s和最大加速度0.3m/s2上升时,电梯乘坐过程对人体心率的影响情况。方法共31名受试对象(21男,10女),随机分成2组。试验组21人(12男,9女)乘坐电梯,对照组10人(9男,1女)不乘坐电梯。研究试验前和试验后2组心率差异有无显著性。用SPSS13.0进行统计分析。结果t检验结果表明,试验前和试验后,2组心率的"组内检验"差异有显著性(P<0.05),但"组间检验"差异无显著性(P>0.05)。结论当电梯以1.75m/s的额定速度和0.3m/s2的最大加速度上升时,乘客心率的变化不是由于电梯加速度引起的,而是由于从坐位到站位这一体位变化引起的。电梯乘坐过程不会引起乘客心率的显著变化。更多还原

【Abstract】 [Objective] This paper researches on the effect of elevator ride on human′s heart rate when the elevator ascends at the rated speed of 1.75 m/s and maximum acceleration of 0.3 m/s2. [Methods] 31 subjects (21 males, 10 females) were participated in the experiment. They were divided into 2 groups randomly. The experimental Group contained 21 subjects (12 males, 9 females). They rode elevators. The Control Group contained 10 subjects (9 males, 1 females). They did not ride elevators. It was researched whether there were significant differences for the heart rate of the 2 groups before and after the experiment. SPSS13.0 was used for statistics. [Results] "Within Group t test" shows there are significant differences for heart rate both of the 2 groups before and after the experiment (P < 0.05) but "Between Group t test" shows there are no significant differences for the 2 groups both before and after the experiment (P > 0.05). [Conclusions] When the elevator ascends at the rated speed of 1.75 m/s and maximum acceleration of 0.3 m/s2, the changes of human′s heart rate are not due to the elevator acceleration, but because of the posture changes from sit to stand. Elevator ride will not change human′s heart rate significantly.更多还原
