英文摘要：

With the development of radio astronomy, the EMC （ electromagnetic compatibility） problems of radio observing systems are becoming increasingly severe. Mastering cable wiring of such systems can benefit EMC project management and help improving system design. Based on the components and characteristics of electromagnetic compatibility of the Urumqi VLBI station, we analyze the electromagnetic compatibility of the systems under the adopted cable wiring. We subsequently propose shielding, filtering, and grounding methods to provide engineers valuable schemes to solve practical problems of electromagnetic compatibility. However, our work is only an initial stage, and more practical work is needed in the future according to our tests and simulations.
