negative temperature

基本解释

Based on negative temperature coefficient resistance(NTCR), a fine multiple channel temperature measurement system was designed.
以负温度系数热敏电阻为核心器件设计了多通道高精度温度测量系统。
Temperature-depended resistivity of carbon nanotube film is measured and the results show negative temperature effect because the resistivity is decreased as the temperature increased.
测定了碳纳米管膜电阻率随温度的变化，结果表明，碳纳米管膜的电阻率随温度升高呈下降趋势，表现为负的温度效应。
The strength of negative temperature concrete is tested with supersonic-rebounding method. The results state that the method is suitable to test the strength of negative temperature concrete.
本文将超声回弹综合法用于负温混凝土强度检测。结果表明，超声回弹综合法可以用于检测和评定负温混凝土的强度。
