PETSc (Portable, Extensible Toolkit for Scientific Computation) 是美国能源部ODE2000 支持开发的20 多个ACTS 工具箱之一，由Argonne 国家实验室开发的可移植可扩展科学计算工具箱，主要用于在分布式存储环境高效求解偏微分方程组及相关问题。(PETSc (Portable, Extensible Toolkit for Scientific Computation) is ODE2000 U.S. Department of Energy to support the development of one of more than 20 ACTS Toolkit, developed by the Argonne National Laboratory' s Portable, Extensible Toolkit scientific computing, mainly used in the distributed memory efficient environment for solving partial differential equations and related issues.)

算符优先的计算器，用于编译原理的课程作业(caculator for opp)

利用扩展卡尔曼算法( EKF)对高动态直接扩频信号的载波相位和频率进行了估计,并利用载波辅助技术测量载波相位的变化值来 校正伪码延时环,减小多普勒频移对伪码延时的影响,得到了精确的延时估计值,提 高了伪码延时锁定环的动态跟踪性能.(The PN delay loop is adjusted through measuring the varied value of carrier phase with carrier aiding technology. The effect of Doppler shift on PN code delay is reduced through carrier aid- ing technology. The precise delay estimation is obtained. The dynamic tracking performance of the PN delay loop is improved.)
