美国《地震情报通报》1979年第11卷1期刊载马登(Theodore R.Madden)写的题为《用电法监测应力—应变》的文章,摘译如下:电阻率—应变监测的实际情况能否测出应力变化引起的电阻率变化依赖于我们是否能以足够高的灵敏度测出电阻率的变化。并且也依赖于背景噪音是否足够稳定,以使任何由应力所引起的变化能够产生显著的 The article by Theodore R. Madden, entitled “Monitoring Stress-Strain by Electrical Methods,” is contained in the American Seismological Information Bulletin, Volume 11, Number 1, 1979, and is translated as follows: The actual situation of resistivity-strain monitoring Whether or not the change in resistivity caused by the change in stress depends on whether we can measure the change in resistivity with sufficiently high sensitivity. And also depends on whether the background noise is sufficiently stable so that any stress-induced changes can produce significant
