摘　　要：为了加强对磁法勘察工作的管理和保证工作质量,为适应科学技术的进步和发展,特别是磁法仪器的不断提升和更新,适时修订相关的技术规程或者工作规范是十分必要的。修订技术规程或者工作规范亦应该契合实际,一是规定明确,二是在保证质量的前提下便于生产单位参照执行。笔者就《地面高精度磁测技术规程》的关于仪器噪声检测时探头的安全间距规定进行探讨,结合相关的磁测技术规定和教科书的要求及专门的试验结果,通过专门实验进行分析讨论,引用实例进行说明,认为并建议对上述规定进行修订。In order to improve the management of magnetic prospecting, ensure the quality of field work and adapt the management to the development of science and technology, especially to the improvement and enhancement of magnetic instruments, it is necessary to make timely revision of the relevant technical regulations or operational standards, which should agree with the actual conditions. It means that the regulations should be clearly determined and easily executed by subordinate production units. This paper discusses the safety separation distance between probes during the noise testing of magnetometers before the operation mentioned in ＂Technical Regulations of High Precision Grounded Magnetic Measurement＂ based on certain detailed field experiments. In combination with related technical regulations and the requirements of the textbooks as well as special test results, the authors propose some suggestions for revising the above regulations after the comparison and analysis of the results.
