摘要
在分析了Seg-D标准格式的基础上,得出了反换算系数(MP值)的具体定义,并对行业标准中反换算系数(MP值)在不同的格式版本中的具体存储方式进行了总结。拓展灵敏度这一物理概念的理解,将其看成是采集系统输入与输出之间的传递函数,提出了系统灵敏度的概念,将采集系统设计的关键参数融合到系统灵敏度中,建立了采集系统设计公式,结合实际的仪器设计建立系统灵敏度与反换算系数(MP值)之间的联系,进而讨论了综合考虑采集系统的前放增益、模数转换芯片量程和数据的存储格式设计MP值的重要性。
Based on the analysis of the standard format of SEG-D, the anti-conversion factor （MP value） of specific definitions and the storage method of anti-conversion factor （MP value） of the specific storage are summarized and analyzed in different versions of SEG-D formats. Based on regarding sensitivity as transfer function of input and output, the con- cept of system sensitivity is defined. In the definition of the system sensitivity, various fac- tors that influence the design of MP value are considered. Then the formula that design ac- quisition system is established. Finally, the importance of comprehensively designing MP value is discussed based on preamplifier, range of A/D and storage format.
