给出了一个解决方案的热传导问题，其中一个球产生热量，在一个利率是成比例的时间提高到负二分之一的权力，是嵌入在一个无限的介质。该溶液用于热敏电阻探针技术，用于测定润湿热敏电阻表面的介质的热导率和扩散率。将热敏电阻珠视为球形分布热质，给出了珠与介质的耦合热响应。球和周围介质中的典型温度分布。
A solution is given for the heat conduction problem in which a sphere generating heat, at a rate which is proportional to time raised to the minus one-half power, is embedded in an infinite medium. The solution is of use in the thermistor probe technique for the determination of both the thermal conductivity and diffusivity of media which wet the surface of the thermistor. The thermistor bead is treated as a spherical distributed thermal mass and the coupled thermal response of the bead and the medium are presented. Typical temperature profiles both in the sphere and in the surrounding medium are presented.
