地震组合编码记录的研究 (Seismic Group Coded RecordingConsiderations)Thomas A.Iha,Texas Instsuments (S15.1) 本文略述地球物理数据采集时使用6250bpi组合编码记录(GCR)的优缺点.GCR在一般应用中日趋普遍,因此介绍了从1600bpi相位编码(PE)记录突变到GCR时应预先注意的事项。其优点是野外人员在不良环境中操作时可保证获得完整的资料。选择一台符合需要的磁带驱动器是保证长期无故障以及获得完整资料的关键。本文还讨论了其性能和设计,以便有助于选择合适的数据记录方法。重要的问题是GCR转换时野外队工作合理和投资迅速见效。本文例举了一个事实,
Seismic Group Coded Recording Consions Thomas A. Iha, Texas Instuments (S15.1) This article outlines the advantages and disadvantages of using a 6250bpi Combined Encoding Record (GCR) for geophysical data acquisition. GCR is increasingly used in general applications This is why it is important to note the precautionary precautions that should be taken when a 1600bpi phase encoding (PE) record is mutated to a GCR. The advantage is that field personnel are guaranteed complete information when operating in adverse environments. Choosing a tape drive that meets your needs is the key to ensuring long-term, trouble-free access to complete information. This article also discusses its performance and design to help you choose the right data logging method. The important issue is that field teams work reasonably well and invest quickly and effectively when GCR transitions. This article illustrates the fact that,
