Abstract: The present invention relates to a groundwater circulation well system with pressure-adjustable hydrodynamic cavitation, including a circulation well body, a sucked and injected water circulation assembly and a hydrodynamic cavitator. The sucked and injected water circulation assembly is based on a water suction and injection pump. The hydrodynamic cavitator is provided, inside a vortex chamber, with a vortex water inlet column capable of changing a water passing aperture. The hydrodynamic cavitator is capable of changing a bubbling pressure and a breaking pressure of hydrodynamic cavitation bubbles in the vortex water inlet column. The hydrodynamic cavitator generates vortices in the circulation well body to accelerate uniform mixing of a remediation agent and the groundwater. Energy from collapsing and bursting of the hydrodynamic cavitation bubbles activates the remediation agent such that contaminants in the groundwater are efficiently degraded.

Abstract: The disclosure provides the use of a plant in the preparation of medicines and health products for preventing and treating ovarian injury. The application found that seabuckthorn fruit pulp and seabuckthorn seed oil have good preventive and therapeutic effects on ovarian injury. Seabuckthorn fruit pulp and seabuckthorn seed oil can prevent mouse ovarian injury and estrus cycle disorders, and can improve ovarian reserve, etc. Meanwhile, they also have good therapeutic effects on the above-mentioned injuries. This application provides a basis for the prevention and treatment of ovarian injury directly by seabuckthorn fruit pulp and seabuckthorn seed oil.

Abstract: In one embodiment, the decoupling apparatus includes a conductive body adapted to be arranged in the antenna to act as a radiation part of the antenna for transmission of electromagnetic waves with a frequency; and at least one slot formed on the conductive body, wherein the at least one slot comprises a dividing part extending to an edge of the conductive body to divide the edge and an intersecting part intersecting with the dividing part. With the radiation part including the decoupling apparatus, the different band radiation units do not need to be far away from each other to obtain good performance.

Abstract: In one embodiment, the decoupling apparatus for an antenna, includes a body and a cross-finger portion coupled to the body and configured to change a capacitance of the decoupling apparatus. The cross-finger portion includes a first plurality of fingers extending along a first direction; and a second plurality of fingers extending along the first direction. At least one of the second plurality of fingers is provided between adjacent two fingers of the first plurality of fingers, and at least one of the first plurality of fingers is provided between adjacent two fingers of the second plurality of fingers.

Abstract: The present disclosure provides a radiator, an antenna, and a base station. The radiator comprises a conductor adapted to be arranged in an antenna for transmitting and/or receiving electromagnetic waves; and a pair of slots formed in the conductor and intersecting at a predetermined angle, each of the pair of slots comprising an elongated section at the middle thereof and widened sections at both ends thereof such that the conductor is divided by the pair of slots into: a continuous outer frame portion; and an enclosed portion surrounded by and connected to the continuous outer frame portion. Thus, the bandwidth of the patch antenna can be significantly broadened while maintaining the advantages of light weight, easy layout, wide range of applications, small size, low cost, etc.
