Abstract

The invention relates to an ice-core solid direct current conductivity measurement system and solves the problem of low ice-core conductivity detection accuracy. The ice-core solid direct current conductivity measurement system comprises a working platform, a control unit, a drive unit, a detection unit for measuring movement displacement of the drive unit, a high-voltage circuit and a probe, wherein the probe is arranged on the drive unit and is connected with the high-voltage circuit; the high-voltage circuit is connected with the control unit; after the high-voltage circuit is electrified and an ice core is fixed to the working platform, the drive unit drives the probe to slide along the surface of the ice core, thereby enabling the control unit to calculate the conductivity of different positions of the ice core according to the detection unit.

Description

technical field [0001] The invention relates to an ice core solid DC conductivity measurement system. Background technique [0002] Polar ice cores are good carriers of climate and environment information, with a series of advantages such as high information fidelity, long time series, high resolution, and less human disturbance. They are important objects and information sources for climate and environment research. The measurement of electrical properties of solid ice cores is almost non-destructive to ice cores, and has a series of advantages such as fast, simple operation, low cost and high resolution. It is widely used in the analysis and research of polar ice cores, and is usually the first batch of analytical data of polar ice cores. , is an important means of quickly locating major climate events and ice core cross-dating. Ice core solid DC conductivity measurement technology is used to measure the conductivity of the ice core section, and the signal is obtained by ...
