A method of production of semiconductor light emission devices for forming stripes of two multilayers having different emission wavelengths on a substrate, including the steps of: depositing a first multilayer including an active layer on the substrate; selectively etching the first multilayer to form a plurality of adjoining pairs of stripes of the first multilayer; depositing a second multilayer including an active layer on the substrate and the stripes of the first multilayer; selectively etching the second multilayer to form a plurality of adjoining pairs of stripes of the second multilayer on the substrate between the stripes of the first multilayer; and dividing the substrate between adjoining pairs of stripes of the first multilayer and between adjoining pairs of stripes of the second multilayer to divide it into semiconductor light emission devices provided with a stripe of the first multilayer and the second multilayer having different emission wavelengths.

The invention discloses a balanced production scheduling method based on a multi-product and multi-production line production mode, and belongs to the field of production scheduling methods for enterprises. This production scheduling method takes into account the enterprise's capacity balance, load balance, product production balance, and configuration production balance. This balanced production scheduling method proposes a new method to achieve production leveling and has been successfully applied. Through this method, each product is transformed and produced in batches in turn according to the optimal production sequence on the production line. Compared with the existing technology, through this method, the plan can be quickly scheduled, which greatly reduces the user's operation, greatly shortens the user's production scheduling time, and makes the enterprise's production scheduling no longer need to rely on individuals factor, more accurately.

The invention relates to a lamplight deepwater net foil fishing device which comprises a barrier net of which the net surface is arranged in the left-right vertical direction; and a standing net cage body is arranged on each of the two sides of the middle part of the barrier net. Each standing net cage body comprises a left side wall net, a right side wall net, a cover net, a bottom net and a rear wall net, wherein an upper line of the left side wall net, which is provided with a plurality of floaters, is connected with the left side line of the cover net; a lower line of the left side wall net, which is provided with a plurality of pendants, is connected with a left side line of the bottom net; an upper line of the right side wall net, which is provided with a plurality of floaters, is connected with a right side line of the cover net; a lower line of the right side wall net, which is provided with a plurality of pendants, is connected with a right side line of the bottom net; each rear wall net is positioned on one side of the standing net cage body, which is far away from the barrier net; an upper line of the rear wall net is connected with a rear side line of the cover net; and a lower line of the rear wall net is connected with a rear side line of the bottom net. The invention aims to provide the lamplight deepwater net foil fishing device which can lower the labor intensity of staff and production cost, guarantees safety production, improves fishing yield, can catch fish in various water levels, and has obvious economic benefits.

The invention discloses a preparation method for a copper nanotube with copper oxide nano-particles embedded therein. The preparation method comprises the following steps that cuprous chloride is dissolved in oleylamine and stirred evenly, and a mixed solution is obtained; the mixed solution is moved into a stainless steel reaction still, then the stainless steel reaction still is put into a drying box, temperature is fast raised to hydrothermal reaction temperature, and standing is carried out for a reaction; after the reaction is completed, the reaction still is taken out of the drying box and cooled to room temperature, a product in the reaction still is taken out and washed, and then a pure copper nanowire is obtained; the pure copper nanowire is put into a closed reaction vessel full of damp air, oxidization is carried out in the constant-temperature environment, and copper oxide hollowed nanofibers with copper oxide nano-particles embedded therein are obtained; and the copper oxide hollowed nanofibers with the copper oxide nano-particles embedded therein are put into atmospheric-pressure plasma equipment, hydrogen plasma surface reduction treatment is carried out, and the final product can be obtained. The method is mild and simple, the raw material cost is low, the production efficiency is high (the consumed time is short), and the product morphology is easy to regulate and control.

The invention relates to an oil, gas and water three-phase liquid mixing device which is characterized by comprising an upper joint, wherein the upper joint is connected with an oil transportation pipe, the other end of the upper joint is connected with a disturbing flow device, and the other end of the disturbing flow device is connected with a lower joint used for connecting an oil outlet pipe;the disturbing flow device comprises a plurality of disturbing flow sleeves in threaded connection, each distributing flow sleeve is internally provided with a cylindrical central through hole the inner diameter of which is same as the inner diameters of the oil transportation pipe and the oil outlet pipe, and two distributing flow plates are arranged in the central through hole at intervals; each distributing flow plate is of a circular ring shape and is provided with a plurality of distributing flow sheets at intervals along the circumferential direction. The oil, gas and water three-phase liquid mixing device is simple in structure, convenient to dismount and mount and good in oil, gas and water mixing effect and can be widely applied to the oil, gas and water three-phase liquid mixingprocess.

The invention belongs to the technical field of non-ferrous metal processing, and discloses a method for preparing Ti6Al7Nb titanium alloy ingots, which is suitable for smelting and preparing Ti6Al7Nb titanium alloy ingots with specifications of Φ560-Φ720 mm. The method includes: first, sponge titanium, AlNbTi alloy, Al beans and TiO 2 Dosing according to the ratio required by GB / T3620.1; mix uniformly and press into electrode blocks, vacuum plasma weld the electrode blocks to prepare consumable electrodes; then carry out three vacuum consumable arc melting on the consumable electrodes , the last smelting adopts the melting speed control, and enters the feeding stage in the later stage, and the melting rate decreases step by step. When the reserved weight of the consumable electrode is 30-60kg and the melting speed is 0kg / min, a current of 4-6kA is maintained at 40 ~100min, gradually reduce the depth of the molten pool; after cooling, perform surface machining to obtain finished ingots.
