摘　　要：建立体应变理论气压干扰模型,通过实际观测资料研究了气压对体应变月变和日变的干扰过程,探讨消除干扰的方法,且和水位资料作了对比分析。This article established the theoritical jamming model of atmospheric pressure in volume strain observation, and by using the real observational data the jamming process of monthly change and daily change of volumn strain caused by atmospheric pressure is studied in detail, and the method for eliminating the jamming is discussed. And comparison with the water level data is carried out.
