我们用心脏磁场模型的数据分别加5%，10%和20%的高斯白噪声来模拟受环境噪声影响的检测数据。

We added 5%, 10% and 20% Gauss White Noise, which were used to simulate environment noise, to the computing data of cardiac magnetic field model.

钢管混凝土柱模型试件的应变量级很大，环境噪声影响较大，可采用大阻值和大量程应变片提高应变准确度。

The wide range strain gauge with large electric resistance should be used to improve the test accuracy, because of the large strain in CFT model and the unfavorable influence of environment noise.
