| 摘 要： | 近20多年来国内垂直应变领域一直无人涉及.垂直应变量的获取可将应变固体潮从平面应变观测提升到三维空间应变观测.本文说明了垂直应变观测的必要性,建立了垂直应变观测系统的原始模型,并提出了研制的难点和理论上的解决方法.

| Abstract: | In nearly 20 years,the vertical strain field has been neglected in China.The vertical strain can promote the strain observation caused by earth tide from plane strain to the three dimensional space.In this paper the research necessity of vertical strain observation is explained,and the initial model of vertical strain observation system is built.The research difficulties and its theoretic solution are put forward also. |

| Keywords: | Vertical strain Earth tide Space strain observation Tensor matrix Vertical strain system |
