Besides , there is also some alternatives , such as an inductance conversion using differential transformer and space curve deformeter , and variable resistance pressure transmitter 除此之外还有利用差动变压器和扰曲线应变计的电感变换方式，以及变电阻式压力变送器。

This paper elementarily collects the anomalies of coseismic and post - seismic effect such as seismic activity , crustal deformation and underground liquid and so on observed in china ' s mainland , which include the evident seismic activity ( especially in yunnan ) increase , obvious crustal deformation , such as the abnormal variation of crustal stress and strain in bore volumetric deformeter and the remarkable change of underground temperature , the chemical component , especially the underground water level 初步汇集了在中国陆区观测到的地震活动、地壳形变、地下流体等多学科震时和震后效应的异常变化，包括地震活动性（特别是云南地区）的显著增强；地壳形变观测，尤其是钻孔应变观测记录到地壳应力应变的震时和震后显著变化，以及地下水温度、化学成分、特别是水位的突出变化。
