Local recurrences mainly occurred in the nasopharyngeal cavity and the skull base bone. Dosimetric analysis showed 9 cases of in-field failure, 4 cases of marginal failure, and 2 cases of out-field failure. For the 6 cases of marginal and out-field failure, the main reasons of recurrence were low dose area in target volume due to not strictly following the guidelines of defining field limit, or inappropriately estimating the involved regions of lesions.

局部复发的主要部位为鼻咽腔、颅底骨质；局部复发灶和照射野模拟剂量学分析发现野内复发9例，边缘复发4例，野外复发2例。6例边缘和野外复发的患者，经过进一步分析发现复发与未严格遵循常规设野原则或对病灶范围判断失误造成不适当的照射野边界导致靶区出现低剂量区有关。

即：首先用灰靶理论建立评定方法的数学模型，以能反映武器系统效能的战技性能指标构造各比较方案或模式的指标序列，进而求得各指标序列的标准模式。

This paper measured the constitutive relation of soil in the condition of the low stain-rate by Split Hopkinson Press Bar technology. It offers the reference for study in high stain-rate in the future. And simulated the explosion between soil and concrete by finite element dynamic analysis software LS-DYNA3D. Finished the numerical simulation for power of exploding between soil and concrete in different position of detonator and different scale model. Set out the curves of displacement, velocity, acceleration and pressure of different position. Obtained the destructibility of concrete target in different explosion condition. It offers data reference for theory studying and engineering designing.
