摘　　要：针对核信号特点,根据不同测量要求,探索一种确定最佳数采方案的有效便捷方法。提出用数字方式对同一核信号实现不同频率数采的方案,将同一信号在各种频率下的数采结果进行分析和比较,确定最佳数采频率。尝试对同一核信号的不同部分实现变频采样,以获得足够的精度和最佳的资源配置方案。according to the characteristic of the nuclear signal and different measurement requirements, explore an effective and convenient method to determine the best sampling frequency. Propose using digital means to achieve sampling the same nuclear signal in different frequency. Through analyzing and comparing the signals in different frequency, determine the optimum sampling frequency. Try to simple the different parts of the nuclear signal in different frequency to obtain sufficient accuracy and optimal resource allocation.
