杭州重力变化和地温关系剖析
Analysis of the Relationship between Gravity Change and Subsurface Temperature in Hangzhou
摘要:
地表重力变化受固体潮、海潮、大气潮和其它常规环境因素的影响，但影响不大。是什么未知因素较大程度影响重力变化？2017年1~8月，测得杭州重力并与同期0~320厘米地温变化作比较。发现：重力变化和160~320厘米地温的差值的绝对值变化较好地相对应。由此推测，地表重力变化和深层地温变化可能存在一定的关联。
Abstract:
Surface gravity change is influenced by solid tide, sea tide, atmospheric tide and other conventional environmental factors, but these factors have little effect on gravity change. What unknown factors greatly affect the change of gravity? From January to August 2017, the gravity of Hangzhou was measured and compared with the subsurface temperature change from 0 cm to 320 cm in the same period. It was found that the change of gravity corresponds well with the absolute value of the difference of subsurface temperature between 160 cm and 320 cm. Therefore, there may be some correlation between surface gravity change and deep subsurface temperature change.
