The strengthening method of mixing is to use the cement as curing agent and use the special machine to mix up the soft clay and the cement to make the soft subgrade become the compound subgrade that has concreteness ; stability of water and enough strength 搅拌法加固技术是利用水泥等作为固化剂，通过特制的深层搅拌机械在地基中将软粘土和水泥强制拌和，使软弱土硬结成具有整体性，水稳性和足够强度的地基土。
Different from the traditional enclosure design project of tempest computer , it adopts the idea of combination of hardware and software , and designs a real - time digital signal processing system with the cpld chip as the core which includes visual sample module , algorithm process module and display module 区别于传统的包容式tempest计算机的设计方案，本文设计一个软硬结合的实时数字信号处理系统，系统用专用的cpld芯片为核心搭建硬件电路，包括图像采集、算法处理和显示输出三大模块。
A control system combined superior and inferior , fuzzy controller and pid controller is applied to switching source charger . the comparison research improved the control quality of the system . the shortage of the traditional offline simulation is analyzed , and a new kind of way is suggested to study switching source charger by a digit and analog mixed system combined software and hardware 建立了高频开关电源充电机的非线性模型，分析了充电机控制系统的实现方式，将一种上位机和下位机、模糊控制与pid控制相结合的控制方式应用于充电机控制系统，并进行了对比仿真研究，有利于提高系统的控制质量；分析了传统离线仿真方法的不足，提出一种利用“软硬结合的数字模拟混合系统”来研究开关电源充电机的新思路，对于充电机控制系统的分析设计和快速实现具有重要意义。
