Abstract: The present disclosure provides a display panel and a display device, the display panel includes: an array substrate and an opposite substrate disposed oppositely, the array substrate having a ground terminal, the opposite substrate including a black matrix and a transparent conductive layer, the black matrix including a first part, a second part and an isolation trench which are sequentially disposed, and the isolation trench isolating the first part from the second part; a conductive adhesive connecting the ground terminal with the transparent conductive layer, a part of the conductive adhesive being between the array substrate and the opposite substrate, and orthographic projections of the part of the conductive adhesive and the first part on the array substrate being not overlapped; and a blocking structure in contact with the part of the conductive adhesive and configured for preventing the conductive adhesive from overflowing to the first part.

Abstract: A scheduling method and system for the operation of reservoirs to recharge freshwater for repelling saltwater intrusion under changing conditions. Research data of a research area is collected, the research area is generalized, and the river network topology of the area is constructed; the research data acquire the seawater flow data of each station in the research area for N time periods, analyze the correlation between the flow of a predetermined station and the saltwater intrusion and build a seawater flow spatial-temporal evolution model; rainfall data and freshwater runoff of each station are acquired to analyze the variation trends of freshwater flow and hydrological regime of each station and a first ending point and build a freshwater flow spatial-temporal evolution model; and a scheduling model for recharging freshwater for repelling saltwater intrusion is built for simulation, a scheduling method is provided, and a scheduling scheme set is formed.

Abstract: Provided are flotation system and method for crushing, separating and washing waste plastics. In a direction of transporting materials, the flotation system includes a crusher, a flotation tank, a multi-functional rubbing and separating device, a washing tank and a dehydrator which are connected in turn; the flotation tank and the washing tank are disposed abreast; the floatation tank is a straight launder, and the washing tank is a U-shaped launder; and the discharge port of the flotation tank and the feeding port of the washing tank are connected via the multi-functional rubbing and separating device. The method is to crush the waste plastics first and then execute multiple stages of washing and separating. The flotation system and method herein are capable of improving the effect of washing waste plastics effectively and improving the quality of products.

Abstract: Provided is a multi-functional rubbing and separating device, comprising a main body, a rotating axle and lapping blades; wherein a feeding port is disposed on one end of the main body and a discharge port is disposed on another end; the rotating axle and lapping blades are disposed inside said main body; the lapping blades are distributed on outer cylindrical surface of the rotating axle; and multiple through-holes are disposed on an sidewall of the main body. The multi-functional rubbing and separating device herein is added between a flotation tank and a washing tank, which can effectively improve the washing quality for waste plastics, thereby separating waste plastics and impurities more thoroughly and improving the quality of recycled products.
