介绍了热导探头的基本原理。基于此原理研制的薄探头，其重复性为5.3%，相对误差小于6.0%。用该探头测量了猪脂肪、肉、肝、肾、活蛇头和死蛇头的导热系数，发现水分含量对生物组织导热系数的大小有重要影响。该探头可在-40至150摄氏度的温度范围内使用。
The basic principle of the thermal conductivity probe is described. Thin probes were developed based on this principle, with a reproducibility of 5.3% and relative error less than 6.0%. Each measurement can be completed in 90 s and the temperature increase can be controlled within 2 degrees C. Using the probes, the thermal conductivities of pig fat, meat, liver, kidney and live and dead snake head were measured and it was found that water content plays an important role in influencing the magnitude of the thermal conductivity of biological tissues. The probe can be used over a temperature range from -40 to 150 degrees C.
