Abstract: A filter assembly includes a filter holder, a first filter set, a second filter set, a third filter set, and a fourth filter set. A first category of filters is capable of changing light effect by rotating. The first category of the filters is served as the first filter set, which is connected to the filter holder, and the light effect is changed by the rotation of the first filter set relative to the filter holder. A second category of filters changes the light effect by two filters relatively rotating or synchronously rotating with the first category of the filters. Regardless of form of rotation, a third category of filters does not change the light effect. The third category of the filters is served as the fourth filter set, which is disposed on a side of the third filter set facing away from the filter holder.

Abstract: Disclosed is a neural network model optimization method based on an annealing process for a stainless steel ultra-thin strip, which belongs to the technical field of data analysis. Aiming at the defects of a size effect caused by a difference of the stainless steel ultra-thin strip from a macroscopic size, a poor adaptability of a common stainless steel mechanical property prediction method and the like, and a good capability of a neural network for processing a complex nonlinear problem, the method comprises modeling various factors influencing annealing of the stainless steel ultra-thin strip by utilizing an artificial neural network, thus predicting and controlling a mechanical property and a microscopic structure after annealing.

Abstract: A method for producing a stainless steel foil comprises the following steps: rolling a raw material steel coil in an intermediate rolling process comprising three rolling processes; rolling the finished product in the rolling process; annealing and straightening the finished product. The application also provides a stainless steel foil prepared by the method. The method can solve the defect that the high strength and high plasticity of the ultra-thin stainless steel foil are difficult to meet at the same time.

Abstract: The present disclosure provides a filter mounting structure, which includes a lens connecting pad and a first filter frame. The lens connecting pad is provided with a rotation adjusting ring and a mounting ring. The mounting ring and the rotation adjusting ring form a fastening connection therebetween. The mounting ring is provided with a limiting groove. The first filter frame is provided with a limiting block. The first filter frame is attracted on the mounting ring. The limiting block is received in the limiting groove. The rotation adjusting ring rotates to drive the mounting ring to rotate, and the mounting ring rotates to drive the first filter frame to rotate. The filter mounting structure further includes a second filter frame movably attracted to an end of the first filter frame away from the mounting ring, the second filter frame is rotatable relative to the first filter frame.

Abstract: A device and a server are provided. The device receives a communication message including contact displaying information including a portion of contact information of a target, displays the portion of the contact information included in the contact displaying information, and, in response to a selection of the portion of the contact information that is displayed, adds the portion of the contact information of the target to an address book.

Abstract: A communication message, which carries contact displaying information of a target contact may be received. The contact displaying information of the target contact may be displayed on a communication interface. Contact information of the target contact may be obtained when a select instruction corresponding to the contact displaying information of the target contact is received. The contact information of the target contact may be added to an address book.

Abstract: A method for making a thin ceramic part involves making a casting slurry including a ceramic powder, a solvent, a binder, a plasticizer, and a dispersant. The casting slurry is tape casted to achieve a single layer green tape. At least two single layer green tapes are laminated to form a green tape lamination. The green tape lamination is dry pressed, dried, shaped, degreased, and fired to achieve the exterior component required.
