| 摘 要： | 随着列车速度的不断提高，多普勒效应的影响逐渐增强。在频率容差和多普勒效应的共同作用下，有可能造成在现有场强分布情况下，音频输出信纳比会显著低于TB／T3052—2002的规定。建立更严格的频率容差标准，成为消除这种影响的较好方法。

| Abstract: | With the increase of train speed, Doppler Effect gradually becomes aggravated. Under the combined impact of Doppler Effect and frequency tolerance, audio frequency output SINAD could be significantly lower than the provision of TB/T3052-2002 in the condition of existing radio field strength distribution. Through the establishment of stricter standards for frequency tolerance, such impact might be weakened. |
