| 摘 要： | 在不同的磁场强度下,对水和油系列的导热实验进行了研究.结果表明:工质的升温速率随磁场强度而变化,且磁场强度越强,磁化时间越长,升温速率就越大;磁场作用下能使水和油的比热容和油的黏度降低.同时对有无磁场下的水和油导热特性进行了对比,分析了水和油在磁场作用下的导热规律及磁场作用下水和油导热的微观机理.

| Abstract: | Under the different magnetic field strength,the series heat conduction experiment used the water and oil indicate that,the working substance heating rate changes along with the magnetic field strength,and the magnetic field strength is stronger,the magnetization time is longer,the heating rate is bigger;simultaneously under the magnetic field function,cause water and oil's specific heat capacity and the oil viscosity reduce.this article preliminary study the contrast that the water and oil heat conduction c... |
