Abstract: A novel method for strengthening and reinforcing ancient books is provided. Such treatment method comprises: first placing the ancient books to be treated in a closed strengthening and reinforcing device; after sealing, performing dehumidification operation and vacuumizing operation on system in sequence to maintain the system dry; and after the system is stable under negative pressure, turning on a fan set, directly delivering a strengthening and reinforcing powder to the strengthening and reinforcing device via a gas pipe, or atomizing a strengthening and reinforcing solution through a ultrasonic atomizer and then delivering the atomized solution to the strengthening and reinforcing device via the gas pipe, so that the ancient books to be treated absorb the strengthening and reinforcing agent sufficiently and evenly; and meanwhile monitoring pH value and humidity of the ancient books, thereby implementing strengthening and reinforcement of the ancient books.

Abstract: The method comprises the steps of: first, providing a sensor, the sensor consisting of a group of PCB copper foils; second, providing a depth detection signal Ftest which can change the detection frequency along with the change in detection depth, and applying the depth detection signal Ftest to the big and small polar plates of the sensor in the step S01 to form an electromagnetic field between the big polar plate and the small polar plates; third, providing a self-calibration signal Fcal acting on the big polar plate, to adjust a phase difference between the big polar plate and the small polar plates, thereby improving the detection sensitivity; and finally, performing shaping and phase comparison on signals output from the big and small polar plates driven by the depth detection signal Ftest, and processing signals output after filtering the phase-compared signals to judge the condition of a medium at the current detection depth.

Abstract: A circuit and a method for detecting a medium under a gypsum board are provided. The method comprises: first, providing a sensor, the sensor consisting of one group of printed circuit board (PCB) copper foils, namely, forming left and right polar plates by two pieces of completely identical PCB copper foils; next, providing a detection drive signal ClK to be applied to the left and right polar plates so that an electromagnetic field is formed between the left and right polar plates and the earth; further, providing a waveform shaping and phase difference circuit so that each polar plate can generate a phase difference relative to its own drive signal; and then, providing an phase inverter circuit to achieve waveform inversion so as to facilitate filtering and amplification of tiny signals, and sampling direct-current voltage signals of the two polar plates by a micro controller unit (MCU).
