Abstract: A pneumatic fracturing method for exploiting shale gas, the method including: 1) applying a compressed gas for a first period of time at a first pressure to a shale formation; 2) applying the compressed gas for a second period of time at a second pressure to the shale formation; and 3) repeating steps 1) and 2) to produce fissures in the shale formation. A temperature of the compressed gas is at least 80° C. A maximum pressure of the compressed gas is at least 25 megapascal, and a minimum pressure of the compressed gas is between ¼ and ? of the maximum pressure.

Abstract: A stress monitoring device of elasto-magneto-electric (EME) effect type, for monitoring stress of a structural component of ferromagnetic materials, includes a magnetic field generating unit, a magneto-electric (ME) sensing unit, a support skeleton, and a signal controlling and conditioning instrument. Under the control of the signal controlling and conditioning instrument, the magnetic field generating unit generates a magnetic field for magnetizing the structural component. The ME sensing unit outputs an electrical signal VME characterizing the magnetic field without a need of external power supply. This electrical signal VME is analyzed and processed by the signal controlling and conditioning instrument to output a magnetic characteristic value Vst corresponding to the changes of the external forces that are exerted on the component. This stress monitoring device realizes on-line, real-time, and nondestructive monitoring, as well as off-line nondestructive monitoring.

Abstract: One aspect of the disclosure provides an application implementation method. In one embodiment, the method comprises receiving a behavior configuration table of an application to be implemented. The behavior configuration table is sent by a service end and includes identifications of Application Programming Interfaces (APIs) and configuration information corresponding to behaviors contained in the application to be implemented. The method further comprises implementing the application to be implemented according to the identifications of the APIs and the configuration information corresponding to the behaviors contained in the application to be implemented.

Abstract: An electronic device with one or more processors, memory, and a display obtains, from a server, a software recommendation notification, where the software recommendation notification at least comprises a name of recommended software. The device also displays, on the display, the software recommendation notification in a notification bar, where the notification bar is in a peripheral region of the display. The device: detects a first user interaction with the software recommendation notification; and upon detecting the first user interaction with the software recommendation notification, displays descriptive information corresponding to the recommended software.
