The DCdrift is evaluated and compared with some experimental results.
估算了直流漂移值并同实验结果作了比较。

The results show that the effects of the DCdrift can be decreased effectively either by software algorithm or hardware high pass circuits.
结果证明，用软件算法和硬件高通滤波电路都可以有效地降低直流漂移的影响。

Because in U-I model flux observation pure integration element is adopted, it brings about two problems of DCdrift error and initial integration error.
