摘要： The invention is to provide a base paper for a raising seedling pot and a raising seedling pot produced from the base paper, wherein while the base paper maintains a sufficient strength during raising seedlings and planting in the field, it is degraded over time by soil microorganisms after transplanting in the field and is produced by using a crosslinking agent that does not contain formaldehyde, resulting in a reduced burden on the environment; the base paper for a raising seedling pot, wherein a citric acid crosslinking agent, as a crosslinking agent for cellulose, is used in order to block the hydroxy group of cellulose in paper through crosslinking; and the raising seedling pot produced by molding and processing the base paper.

摘要： A novel device for deacidifying, reinforcing and strengthening ancient books is provided. The device includes a double-open front door, a fan set, a dehumidifier, a vacuum pump, a light, a middle partition, a gas pipe hole, a rear panel, an ultrasonic atomizer, a gas pipe and a pulley track. The double-open front door is provided on one side face of the device. The middle partition divides the device into an upper part and a lower part, bottom faces of the upper part and the lower part are each provided with the fan set. The dehumidifier, the vacuum pump and the ultrasonic atomizer are arranged at an external surface of the rear panel opposite the double-open front door. The gas pipe locates at and runs through an upper part of the middle partition, and that section of the gas pipe is provided with the gas pipe hole The gas pipe is connected with the ultrasonic atomizer.
