The invention relates to the technical field of PE wrapping films, in particular to a multi-layer co-extrusion PE stretching wrapping film which overcomes the defects in the prior art and comprises the following components: polyethylene, polyhedral oligomeric silsesquioxane, ethylene-vinyl acetate, bonding resin, polypropylene, nano zirconium oxide particles, polyether-ether-ketone, an antistatic agent, a slip agent and an ultraviolet absorbent. According to the invention, novel nano materials such as nano zirconium oxide and polyhedral oligomeric silsesquioxane are introduced, and a material formula and a preparation process are optimized, so that the multi-layer co-extrusion PE stretching and wrapping film with higher wear resistance, high temperature resistance, chemical resistance and mechanical strength is developed, and increasingly complicated and diversified market requirements are met.

This invention belongs to the field of digital camouflage technology, specifically relating to a digital camouflage pattern design method based on trend function constraints. It includes: Step 1: Pre-segmenting the background image, then obtaining the step size, turning angle, and step size probability distribution P. l and the probability distribution of the turning angle P θ Step 2: Normalize the frequency and pixels of the background image, obtain the weights corresponding to the edges, construct a Laplacian sparse matrix, generate a probability matrix, match patch labels, calculate the density of texture patches, adaptively generate corresponding convolutional modules, and finally design destructive edges; Step 3: Perform matching and clustering of the main color to output the final camouflage pattern. This invention proposes a digital camouflage pattern design method based on trend function constraints. By defining a trend function to estimate the boundary probability between pixel nodes, digital camouflage patches are outlined, and finally, the background main color is filled to distort the target surface features, thereby realizing the digital camouflage pattern design.

A gate oxide process, first dry oxidation treatment, wet oxidation treatment and second dry oxidation treatment are carried out on the substrate in sequence, so that the silicon-chlorine bond is formed between the third oxide layer and the substrate, compared with only reducing the light doping leakage ion implantation dose and increasing the light doping leakage energy, the hydroxyl introduced by the wet oxidation treatment not only improves the chlorine activity, but also as a transport carrier makes the chlorine efficiently enriched in the new oxide layer, the high concentration of chlorine fills the oxygen vacancies, reduces the bulk trap density, the silicon-chlorine bond formed by the second dry oxidation treatment has a deeper trap energy level, which can reduce the interface state density and improve the device's ability to resist hot carrier damage. Moreover, the hydrogen introduced by the wet oxidation treatment is removed in the second dry oxidation treatment, thereby avoiding the situation that the silicon-hydrogen bond is broken, the hot carrier injection is intensified, and then the degradation chain reaction is triggered, thereby achieving the effect of improving the hot carrier injection effect.
