【Abstract】 The law of geophones’ damping variation with temperature is researched. Damping of geophones in various temperatures is tested, the relative laws are revealed through data analyzing, and some typical response curves are given. Then, the factors which affect damping variable,namely control its temperature response are discussed. Finally, together with the prime experimental result, strategies for achieving flat damping-temperature response are proposed through material optimization arrangement or regulation resistance with temperature compensation coefficient.更多还原
