negative temperature

基本解釋

Based on negative temperature coefficient resistance(NTCR), a fine multiple channel temperature measurement system was designed.
以負(fù)溫度系數(shù)熱敏電阻為核心器件設(shè)計(jì)了多通道高精度溫度測(cè)量系統(tǒng)。
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.
測(cè)定了碳納米管膜電阻率隨溫度的變化，結(jié)果表明，碳納米管膜的電阻率隨溫度升高呈下降趨勢(shì)，表現(xiàn)為負(fù)的溫度效應(yīng)。
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.
本文將超聲回彈綜合法用于負(fù)溫混凝土強(qiáng)度檢測(cè)。結(jié)果表明，超聲回彈綜合法可以用于檢測(cè)和評(píng)定負(fù)溫混凝土的強(qiáng)度。

And if you're below this temperature here, this quantity, p times v it would be negative.
壓強(qiáng)與體積的乘積將變成負(fù)數(shù)，這可能嗎？
