摘　　要：利用心磁图来诊断心脏疾病是目前医学界的一种新方法.心磁信号在测量过程中往往会引入各种噪声,这将影响对心磁信号的进一步分析和计算.因此,降低噪声是心磁信号处理中的一个关键环节.利用双线性变换法对心磁信号的降噪处理进行了初步地研究,并结合一些实际的心磁数据进行了比较与分析,从而展现了该方法的实用性.The diagnose of heart disease utilizing MCC is the new method in medicine. During the measure of the MCG-signals, there are kinds of noise. It affected the effects of the further analysis and calculate. Thus, the reduction of noise is the key in the process of the MCG-signals. In this article, the initial study is shown about the reduction of noise of the MCC-signals utilizing the bilinear transform method, and the practicability of this method is given combining with the actual MCG data.
