The measurement error source of center of cone gravity, arithmetic and uncertainty of ATS are given, and the measurement accuracy of conecenter of gravity is improved.
The model can reflect the dynamic characteristics of the water stage at the conecenter, and it does not require artesian aquifers in balance regions to be of homogeneous media.
该模型能反映漏斗中心水位的动态特性，且不要求均衡区承压含水层为各项同性的均匀透水介质；
