目的：在定量感觉检查中，探讨不同刺激温度变化率对温度觉阈值的影响。
Objective: To understand the effect of different rates of stimulus on thermal threshold.
左手指的冷痛觉与左足背的热痛觉在两种刺激温度变化率所得阈值之间无显著性差异。
There was no significant difference between the thresholds of the cold pain on left fingers, the heat pain on left dorsum pedis.
在刺激温度变化率增加不够大时，冷痛觉、热痛觉阈值可能随温度变化率增加而降低或无差别。
The cool pain and heat pain threshold may degrade or not differentiate when the increase of the rate of stimulus is not enough.
