摘要 讨论了具有一个测量值的电阻网络电导率的反演问题,证明了在一定条件下,反演问题解的存在惟一性,并给出了相应的算法.同时在条件不满足时,给出了调整测量节点位置的方法,使得调整后的反演问题解是惟一的,从而使反演过程得以顺利进行. The inverse problem of resistor network with one measurement is discussed. The existence and uniqueness of such inverse problem are obtained under certain condition. If the condition is not satisfied, an adjusting method is given to make the inverse process work well. Some numerical results are also given.
