The experimental results show that:(1) for ideal spheres, the attenuation coefficient of velocity is constant, the air drag coefficient is slightly affected by the initial velocity and is a linear function of initial velocity, and (2) for real fragments formed by a warhead, the flight performances are different from ideal spheres, the air drag coefficient is affected by the flight velocity and is a linear function of flight velocity.

实验结果表明：(1)对于理想球形钨合金破片，在同一初始速度条件下，衰减系数为常数，空气阻力系数与初始速度有关，两者成线性关系；(2)对于经历爆轰驱动的球形钨合金破片，由于有轻微的质量损失和变形，速度衰减规律与理想球形钨合金破片有明显的区别，空气阻力系数与飞行速度有关，两者成线性关系。

We performed a field experiment by the end of 2004, and based on the data of this experiment, we studied the amplitude degression and corresponding seismic attenuation factor of both single event waveform and cross-correlation function. It is found that, same as single event waveform, cross-correlation function could be used to assess the seismic attenuation.

依据野外现场实验的数据，我们分别以单次和多次激发为源，讨论了事件波形和互相关函数波形的振幅变化及相应的介质品质因子，结果发现，与事件波形一样，互相关函数波形也可以用于计算介质的衰减系数。

整个软件采用模块化设计，充分利用了课题组现有的程序功能，对新增加的功能进行合理的分类和设计，形成了一系列新的功能模块，保证了软件的可扩展性，提高了软件的可维护性。

To avoid or reduce re-analysis, we derived the augmentative matrix variation only in summation of the previous matrices time the outside-perturbed parameters by decomposing the element stiffness and mass matrix. The implicit function of amplitude about design variables such as cross-areas and lengths is changed into simplistic function about the perturbed parameters of design variables. Several methods for determining the value of perturbed parameters are detailed.

为避免或减少重分析，将有限元单元阵进行了分解变换组装，使振幅与设计变量如截面面积、长度的复杂隐函数关系转化为对设计变量摄动参数的显式关系，进而将设计变量摄动参数提取在分解后的几个常数刚度阵、质量阵之外，避免了在迭代求解过程中重组刚度阵与质量阵，较快地获得问题的解。
