用matlab编写的一维两相渗流数值模拟程序，采用隐压显饱法求解含水饱和度和压力，适合油藏数模编程初学者！(Using matlab to prepare a one-dimensional two-phase flow simulation program, the use of implicit pressure explicit saturation method for solving water saturation and pressure reservoir for the D programming for beginners!)

数字控制系统仿真与综合应用：设控制对象为 W1=10/s(1+0.1s)(1+0.05s),采样周期T=0.2s。 （1）采用零阶保持器，将W1(s)转换成W1(z),串接一个计算机调节模型D(z)组成一个典型的数字反馈系统。分别用仿真方法得到系统在单位阶跃输入作用下的响应和系统在单位速度输入时的输出响应。 (Digital control system simulation and comprehensive application: set control object for W1 = 10/s (1+ 0.1 s) (1+ 0.05 s), the sampling period T = 0.2 s. (1) the zero order keep device, will W1 (s) convert W1 (z), the combination of a computer adjusting model D (z) composed of a typical digital feedback system. The simulation method were used to get in the unit step input system under the action of response and system in the unit of output response speed input. )

文章中主要阐述了PN码的捕获，并对以前的各种捕获方法进行了改进。得出了基于FFT的快速捕获算法！(Abstract-A FFT-based parallel acquisition algorithm for Direct Sequence/Spread Spectrum radio navigation system is studied to solve long PN code acquisition using serial method. Frequency domain analysis of FFT to acquire signal is applied in this paper and state transfer function is used to derive the expression of average acquisition time.)
