3results about How to "Point to optimization" patented technology

A product state quantification and remaining life prediction method, comprising: acquiring design data and running data of a product; establishing a design model of the product on the basis of the design data, executing data fusion according to the design data and the running data, so as to obtain a predicted performance curve of the product, and selecting an optimized working state point from the predicted performance curve; and establishing a cost model and an operation flexibility model of the product on the basis of the predicted performance curve, and calculating remaining life prediction of the product according to a performance requirement or a running cost of the product. Quantification and prediction can be executed on the basis of the dynamic performance of a product. In addition, further disclosed are a system and apparatus for implementing the method.

This application provides a display screen, a display screen protective film, and an electronic device. A transmissive layer of the display screen has a first surface away from a display panel, an orthographic projection of each micro structural unit on the first surface and along a thickness direction is located in a pixel region, and a projection area of the micro structural unit is less than or equal to an area of the pixel region. The micro structural unit may be a curved surface. In this embodiment of this application, the pixel region may include a region in which a sub-pixel is located on the display panel, and a spaced region between the sub-pixel and another sub-pixel that is located around the sub-pixel and adjacent to the sub-pixel. In the foregoing display screen, each micro structural unit mainly bends a display light ray of one sub-pixel. This helps reduce a difference in light refraction degrees between different sub-pixels, and further helps optimize a flash point.

This utility model discloses a fracturing flowback fluid flocculation sedimentation tank, relating to the field of fracturing flowback fluid flocculation sedimentation technology. It includes: a tank body, an inlet, a dosing port, a sludge discharge port, and a servo motor. The inlet and dosing port are located at the top of the tank body, and the sludge discharge port is located at the bottom center of the tank body. The servo motor is fixedly located at the upper center of the tank body, and its drive rod passes downward through the top center of the tank body and enters the interior of the tank body. A first conical guide plate and a second conical guide plate are fixedly mounted on the drive rod, with the dosing port pointing towards the first conical guide plate and the inlet pointing towards the second conical guide plate. By fixing the first and second conical guide plates on the drive rod, corresponding to the dosing port and the inlet respectively, this application allows the flocculant and fracturing flowback fluid to smoothly enter the tank body. Simultaneously, the two guide plates rotate together with the drive rod, improving the stability of flocculation sedimentation.
