在地壳运动观测结果的数据中,包含有气压变化、潮汐、降雨等因素的影响。若观测的目的是检测构造起源的地壳运动,这些因素就可以认为是噪声,因此,就希望尽可能地从数据中去掉它们。这样,地壳运动观测人员除了架设把噪声输入作为物理量的观测仪器外,还有必要预先从经验方面知道对其输入的响应函数。同时还进一步希望知道对响应函数给出的物理依据。现在,在气象厅的引处体应变观测点中的17处观测点上设置气压计、在以实时取数据的
The crustal movement observation data include the effects of pressure changes, tides, rainfall and other factors. If the purpose of the observation is to detect the crustal motions of the tectonic origin, then these factors can be considered as noise and, therefore, it is desirable to remove them from the data as much as possible. In this way, crust movement observers need to know in advance the response function input to them in addition to observing instruments that set the noise input as a physical quantity. At the same time, I further want to know the physical basis for the response function. Barometers are now installed at 17 observation points in the meteorological agency’s reference strain strain observation points,
