Abstract: Disclosed is a combined process of integrating stopping-backfilling and carbon storage. The combined process includes the following steps of: determining a cyclic interval of a working face through measured data of a mine pressure of a fully-mechanized coal winning working face; when the stopping distance of the fully-mechanized coal winning working face reaches a backfilling isolation interval, providing a backfilling tarpaulin behind a hydraulic support, and pumping, through a backfilling pipeline, backfilling slurry to a backfilling area along a support beam; when the area is backfilled with the backfilling slurry, injecting supercritical carbon dioxide into the backfilling slurry; and allowing the supercritical carbon dioxide to fully react with the backfilling slurry to solidify the backfilling slurry.

Abstract: Disclosed is a method for backfilling and reconstructing a carbon storage space in an abandoned main roadway and storing CO2. A surrounding rock of the main roadway is surveyed through geophysical exploration technology, and an anchor bolts (anchor cables) are used to reinforce and support an area which has unstable confining pressure bearing. According to a width and a height of the roadway section of the main roadway, a support formwork is forged in advance, and after the support formwork is placed in the main roadway, backfilling slurry is injected to the periphery of the support formwork. Meanwhile, supercritical carbon dioxide is injected into the backfilling slurry and the roadway, respectively.

Abstract: The present invention discloses a method for improving control and detection precision of tidal volume by introducing R value, comprising the steps of: a plateau pressure Pplate is used to calculate a system compliance C with C=?V/(Pplate?PEEP); VT, the tidal volume obtained currently at patient terminal, is calculated with VT=?V×(C?Ctube)/C, wherein ?V is the variation of tidal volume, PEEP is the positive end expiratory pressure and Ctube is the compliance C of the line. Depending on the calculated VT, the tidal volume which is actually obtained by the patients during this period, the processing unit calculates the tidal volume VT?, which the airway is intended to reach during the next expiration period, by VT?=VT+?VT×K wherein K is a scaling factor for control and adjustment, VT is the tidal volume obtained by the patient during the current period, VTset is the presetted tidal volume, ?VT=VTset?VT.

Abstract: An electronic device with a multi-axis turning function has a main body, a rotation member, a display, an operation portion, a first pivot, a second pivot and a third pivot. The main body has a lens positioned on an end thereof and a first axis co-axial with the lens. The rotation member is connected to the main body and has a second axis. The rotation member is rotatable through the first pivot. The display is rotatable through the second pivot. The main body and the operation portion are inter-rotatable through the third pivot. The electronic device with a multi-axis turning function of the present invention is rotatable freely with random angles, overcomes the traditional shortcoming that the display must be positioned on one sidewall of the main body of the electronic device and facilitates a handheld, self-recording function.
