5个f语言有限差分正演程序，应用有限差分法在CPML边界条件下进行2D正演，前四个程序分别对应各向异性介质、各项同性2阶精度、各项同性4阶精度、双相介质4阶精度四种不同情况。最后一个是3D粘弹性介质的程序。(5 f language finite difference modeling, application of finite difference method under CPML boundary conditions 2D forward, the first four programs corresponding to anisotropic media, the isotropic second order accuracy, isotropic 4th order accuracy, double phases 4 order accuracy in four different situations. The last one is the program 3D viscoelastic medium.)

QPSK调制全称Quadrature Phase Shift Keying，意为正交相移键控，是一种数字调制方式。它的频带利用率高，且抗干扰性能强，已经成为现代通信技术中一种十分重要的调制解调方式。本文在介绍了不同数字调制方式原理的基础上，分别利用matlab编程语言和建模仿真工具Simulink实现了QPSK系统的仿真设计，通过仿真图形观察了调制解调过程中各环节的波形，并结合QPSK调制技术的原理，分析了系统的性能，证明了仿真模型的可行性。最后，进一步实现了系统在分别通过理想信道、通过高斯信道、先通过高斯白信道再通过瑞利衰落信道时的仿真设计，对比分析了不同情况下的系统性能。所得出结果与理论基本相符，对于理解QPSK系统的性能并对系统面向实际应用的设计，提供了有效的参考依据。

To solve this instance of the decision problem we must determine whether there is a truth value (TRUE or FALSE) we can assign to each of the variables (x1 through x4) such that the entire expression is TRUE. In this instance, there is such an assignment (x1 = TRUE,x2 = TRUE, x3=TRUE, x4=TRUE), so the answer to this instance is YES. This is one of many possible assignments, with for instance, any set of assignments including x1 = TRUE being sufficient. If there were no such assignment(s), the answer would be NO.
