The white LED chip comprises a silicon substrate, a first buffer layer, a first active layer, a first cap layer, a first groove and a second groove, wherein the first buffer layer, the first active layer and the first cap layer are positioned on the silicon substrate sequentially; the first groove passes through the first buffer layer and the first active layer respectively to extend to the first cap layer, and a second buffer layer, a second active layer and a second cap layer are arranged in the first groove; the second groove passes through the first buffer layer and the first active layer respectively to extend to the first cap layer, and a third buffer layer, a third active layer and a third cap layer are arranged in the second groove; and the first active layer, the second active layer and the third active layer are selected from one of a blue light active layer, a green light active layer and a red light active layer respectively and are the active layers with different colors. When used, the white LED chip can emit red light, green light and blue light simultaneously, and can emit white light after the light with three colors is mixed; and due to the adoption of the silicon substrate which deviates 1 to 9 degrees from a crystal plane (111) in the crystal orientation, dislocation between the buffer layers and the silicon substrate can be reduced.

The invention belongs to the technical field of wooden product production, and relates to color uniformizing of solid wood parquets, in particular to a color uniformizing process for the color shading of the solid wood parquets. The color uniformizing process includes the steps of veneering, hot pressing, balance nourishing, cutting, sanding, primer paint spraying, groove and tongue forming, coating and finished product packaging. The four procedures of wetting, bleaching, coloring and color washing are further included between sanding and primer paint spraying. Timber duct notches are adopted for texture positions of the surfaces of the solid wood parquets, water-based primer paint containing color concentrate is brushed into ducts through the mechanical and physical effects, the color of the texture positions is deeper than the color of smooth positions, surface textures of the parquets seem obvious, and the stereoscopic effect is enhanced. According to the disclosed color uniformizing process, before bleaching liquid is subjected to roller painting, by adding the wetting procedure to light-color portions of timber, the bleaching effect of the bleaching liquid on the light-color portions of the timber is slowed down, and the tone of the light-color portions of the timber can be closer to the tone of the deep-color portions of the timber; and by adding the coloring procedure and the bleaching procedure, the overall tone of the timber can be more consistent, the color of the timber can be lighter, and light-color finished products are easy to process.

The invention discloses a man-machine call optimization method and device, computer equipment and a storage medium, and belongs to the technical field of artificial intelligence, and the method comprises the steps: marking a training corpus, obtaining a training sample set, training a preset initial recognition model through the training sample set, obtaining a user intention recognition model, receiving an intention recognition instruction, obtaining a call text of a current call corresponding to the intention recognition instruction, importing the current call text into the user intention recognition model to obtain a user intention recognition result, determining whether the current call needs intervention of a manual service agent based on the user intention recognition result, and if so, forwarding the current call to the manual service agent. In addition, the invention also relates to a blockchain technology, and the call record of the current call can be stored in the blockchain. The user intention recognition model is constructed to judge the intention of the user in the current call, whether intervention of a manual service agent is needed or not is determined based on the intention of the user, and the man-machine call interaction experience and work efficiency are improved.

The invention relates to a method for processing the color difference of clothing made of a pure cotton fabric, and belongs to the technical field of clothes. The method allows local color difference existing in the clothing made of the pure cotton fabric to be restored to make the tone of the whole clothing consistent, so the value and the quality grade of the clothing are improved.

The high-purity iron pearlescent pigment comprises a pearlescent pigment base material; the outer surface of the pearlescent pigment base material is coated with a Fe2O3 coating layer; several composite layers capable of reflecting and refracting light rays are further coated between the Fe2O3 coating layer and the pearlescent pigment base material; each composite layer is composed of the Fe2O3 coating layer and an auxiliary metal oxide layer containing metal oxides of non-ferrous elements; the auxiliary metal oxide layer is located between two Fe2O3 coating layers. According to the invention, the color purity and brightness can be improved.

The invnetion provides a skin-masking material for adhesion to the skin in order to conceal a region of the skin, when the region has what is considered to be an abnormal appearance, wherein the skin-masking material has good cosmetic coverage when a cosmetic is further applied over the surface of the skin-masking material when adhered to the skin. The skin-masking material includes a contact adhesive layer laminated to one surface of a film layer having stretch properties, and where the average particle diameter of a powder contained in a cosmetic applied to the other surface of the film layer is denoted by d, and the thickness of the film layer is denoted by w, the Rz of the other surface satisfies the relationships d <= Rz <= 60d and Rz <= w. Because the Rz of the other surface is equal to or greater than the average particle diameter d, the majority of the powder of the cosmetic enters the asperities formed on the other surface, and is retained within the asperities.
