Based on the existing water quality monitoring network and monitoring frequency in the study area of the Huaihe River mainstream and its main branch Shaying River, water quality variation on time and space was analyzed in combination with the water quantity changes, and an integrated assessment method for water quantity with different qualities was put forward.

The monitoring frequency is uncertain.

Proper structure design of the infrasonic monitoring arrays is an effective means to restrain the environment noise and enhance the target infrasonic signal.

The design of a frontend circuit in the shortwave noise spectrum monitoring system is made by utilizing superheterodyne reception and direct digtal synthesis techniques.
