Abstract: Disclosed in the present invention are polymorphic forms of a compound and a preparation method therefor and an application thereof. A crystal form III of a compound A uses Cu—K? radiation, and X-ray powder diffraction expressed at 2? angles has characteristic peaks at 12.15±0.20°, 15.98±0.20°, 16.62±0.20°, 17.14±0.20°, 24.32±0.20°, and 26.08±0.20°. A crystal form VII of the compound A uses Cu—K? radiation, and X-ray powder diffraction expressed at 2? angles has characteristic peaks at 12.94±0.20°, 14.41±0.20°, 15.64±0.20°, 17.25±0.20°, 21.75±0.20°, and 24.23±0.20°. The polymorphic forms prepared by the present invention are good in stability, and can be stably stored under the conditions of high temperature and low relative humidity.

Abstract: Disclosed is a coil assembly and an electromagnetic cooking appliance. The coil assembly includes: a coil base, including a bottom wall and a side wall; a first coil and a second coil, fixedly located at the bottom wall and the side wall respectively; and a plurality of magnetic stripe supporters, located at the coil base along a circumferential direction. Each magnetic stripe supporter includes a first mounting part, a second mounting part, and a connecting part connected to the first mounting part and the second mounting part. The coil assembly in the disclosure can effectively reduce the mounting space for the magnetic stripe supporter, and prevent the interference between the magnetic stripe supporter and the circuit board supporter in the electromagnetic cooking appliance.

Abstract: A kinetic sculpture and an intelligent control system are provided which comprise a plurality of movable bases (500), and the movable bases are arranged radially along a circumferential direction around a centerline disposed vertically; a bearing unit (400) is mounted on each of the movable bases (500), a vertical column (100) is mounted on the bearing unit (400), and a blade unit (200) is disposed on the column (100); the bearing units (400) move the columns (100) along the moving paths on the respective movable bases toward the position of the centerline or away from the position of the centerline to achieve combination or separation; the column systems correspondingly control each of the columns (100) to move. The kinetic sculpture enables the blades (201) of the kinetic sculpture to present a contour shape in gathered and separated states.
