Description

technical field [0001] The invention relates to a charge detection technology of wind-blown sand and quick-sand particles, in particular to a real-time measurement system for charge-mass ratio of wind-blown sand and quick-sand grains. Background technique [0002] The wind-sand electric field refers to an electric field that is 2-3 orders of magnitude higher than the atmospheric electric field in sunny days due to the movement of sand and dust with a certain amount of charge in the wind-sand environment. It will affect the strength of wind and sand flow, communication and radar signals, etc. Not only that, the existence of dust in the earth's environment is an important factor in predicting its temperature and seasonal changes, and the understanding of the dust transport process under the action of the wind field is helpful to research in many other fields, such as atmospheric science, remote sensing technology and Geography, etc. Moreover, the electrostatic force of sand ...

AI Technical Summary

Problems solved by technology

There is still a lack of real-time dynamic measurement of the charge-to-mass ratio of wind-blown sand and drifting sand particles, especially in the field under unattended conditions, which cannot deeply reveal the charging law of wind-blown sand

[0005] It can be seen that in the process of realizing the present invention, the inventors have found that at least there are defects in the prior art that the charge-to-mass ratio of wind-blown sand and quick-sand particles cannot be measured in real time and in the field environment.
