摘要
介绍了一种双传感器组成差分结构的伸缩仪,该仪器在武汉地震台进行3个月的试验结果表明:差分式结构明显地提高了伸缩仪的抗干扰能力。
The differential extensometer made up of dual-sensor,which has already installed at about 100 seismotations all over China is introduced.The results of the test for 3 months show that the anti-interference capability of this type of extensometer has been impoved much more then those in common use.
