Methods Two mathematical models were created for preoperative planning of the ablation in spherical tumors. The models were based on the overlapping sphere principle and were deduced and calculated by the regular prism way and regular polyhedron way.

将肿瘤模式化为类球体，根据球体覆盖原理建立数学模型，应用正棱柱法及正多面体法进行推导计算，获得治疗范围与射频针伞径、布针次数的关系式。

Select steam initial temperature from 535℃to 660℃, and initial pressure form16 MPa to 34 MPa, We choose 494 sets of different steam properties in the selected sphere. Making the 494 sets of parameters basing points, We program and analyze how ideal cycle efficiency and relative cycle efficiency and absolute cycle efficiency vary with steam initial properties .
