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。

Cross Entropy method has recently been proposed as a heuristic method.It shows some simple performance in the process of solving combinatorial optimization problems.This paper makes full use of Cross Entropy method to obtain the best estimator for the max-cut problem which is a standard NP-hard problem in graph graphic theory.

交叉熵方法是近几年发展而来的一种启发式方法，在求解组合优化问题中显示出其简单有效的特点，将运用交叉熵方法寻求图论中一个典型的NP困难问题—最大割问题的最优解。

There are many noise sources in measuring the seismometer transfer function, the main noise sources are investigated. The method of cross-special analysis is presented, flow process diagram of computing is given, the algorithms are discussed in detail, such as low-pass digital filter, computing of seismometer transfer function initial values, time domain convolution, bilinear transformation, estimation of power spectrum and cross-spectrum, window functions and preprocessing of measuring data etc.

在地震计传递函数测试过程中的存在多中噪声，本文分析了主要的噪声来源；介绍了用互谱分析方法测试地震计频率特性的基本原理和方法；给出采用该方法确定地震计传递函数的算法流程图；并对计算过程中采用的低通滤波器、地震计传递函数的初值确定方法、卷积运算方法、自谱和互谱估计、采用的窗函数和测试数据的预处理进行了详细讨论。
