Abstract: The present invention discloses glass ceramics, and a production method and a dedicated device therefor. Glass ceramics are prepared by using tantalum-niobium tailings, blind mining of natural stone material is greatly reduced, and comprehensive utilization efficiency of tantalum-niobium tailings is improved. The glass ceramics obtained by the production method and the dedicated device has few bubbles and high strength, and the yield and the quality of the finished product are both improved. Moreover, the idle tantalum-niobium tailings are utilized in the production, so that resources are saved.

Abstract: A respiration monitoring method and a respiration monitoring apparatus are disclosed. The method includes: according to airway pressure data which are measured by the pressure sensor in a respiratory cycle and gas flow rate data which are measured by the flow sensor in said respiratory cycle, calculating an intrapulmonary pressure of an inspiratory phase of a patient and an expiratory pressure of said patient, which pressures correspond to said respiratory cycle; and determining a driving pressure of said patient, which pressure corresponds to said respiratory cycle, according to the intrapulmonary pressure of the inspiratory phase and the expiratory pressure. In this way, a driving pressure can be obtained without manual intervention, such as inspiratory and expiratory hold, and the driving pressure can also be measured in real time; and since ventilation is not interfered with, a patient-friendly effect is also achieved.

Abstract: A preparation method of a low-lactose dairy product rich in honey pomelo fiber includes the following steps: washing, cutting and debitterizing peels of honey pomelos to obtain honey pomelo fiber pieces; sterilizing and cooling milk solution, performing the first-round fermentation by inoculating lactic acid bacteria, centrifuging the fermented milk after curding, collecting precipitates, adding water to the precipitates, and performing homogenizing treatment to obtain the first-round fermented milk; mixing the honey pomelo fiber pieces with the first-round fermented milk, and performing the second-round fermentation by inoculating the lactic acid bacteria; or performing the second-round fermentation by inoculating the first-round fermented milk with the lactic acid bacteria, and then mixing the second-round fermented milk with the honey pomelo fiber pieces; and prefreezing the treated honey pomelo fiber pieces treated in the previous step and then performing vacuum freeze-drying to obtain low-lactose dairy p
