摘要
研究了电热温室中土壤的温度场。根据温度场与电场的相似性,引入计算静电场的广义镜像法,导出了地表为非等温面情况下计算土壤温度场的公式。结果表明,计算数据与测量数据十分接近。
The soil temperature field at electrothermal hot house is studied.Based on the similarity between the temperature field and the electrical field,a formula to calculate the soil temperature field with a nonuniform temperature surface is developed by introducing the generalized mirror-image method calculating the static electric field.The results show that the figures calculated are quite approximate to the figures practically measured.
