一、引言用振子示波器记录模拟曲线的方法获得固体火箭发动机的实验数据由于精度低,处理数据耗时较长,效率低,已经不能满足当前技术发展的需要。发达国家目前普遍采用计算机或微处理机数据采集与处理系统解决这一类的问题。我国也在逐步采用这样的先进技术。但在目前情况下,由于一套计算机数据采集与处理系统耗资较多,一般基层单
I. INTRODUCTION Using the Oscilloscope to Record Simulation Curve Obtaining the experimental data of solid rocket motor can not meet the needs of the current technological development due to its low accuracy, long processing time and low efficiency. Developed countries currently use computer or microprocessor data acquisition and processing system to solve this type of problem. Our country is also gradually adopting such advanced technology. However, in the current circumstances, due to a set of computer data acquisition and processing system cost more, the general grass-roots single
