The invention is about a method of marking ink which is only used to defend fake. The composition of it is: lipidol or lipid, surface active agent, integration agent, water, buffering agent. Their mass percents are: 1,2-hexylene glycol: 5%-15%, butanol: 1-5%, DH-1: 5-10%, EDTA: 0.1-0.5%, MS-1: 0.1-1%, water: the rest. The process is: a. dissolving the colorant in water, b. put the correct percent of 1,2-hexylene glycol and butanol into the solvent, then dropping the MS-1 and EDTA solution when mixing the solvent for 30-50 min, c. put the rest precent of water into the printing ink box. The picture and word would be shown red fluorescence in the UV but blank in the usual light.

This invention relates to a flow-type electrolysis device for enhancing carbon dioxide mass transfer and its application, comprising: a clamping assembly including a first clamping plate and a second clamping plate; at least one set of electrode assemblies, each including a cathode plate and an anode plate, the cathode plate being connected to the first clamping plate and the anode plate being connected to the second clamping plate, the cathode plate having a cathode medium outlet and a cathode medium inlet, and the anode plate having an anode medium outlet and an anode medium inlet; and a bipolar plate located between the cathode plate and the anode plate; wherein the diameter of the bipolar plate outlet is smaller than the diameter of the bipolar plate inlet. This invention utilizes the electrolyte flow characteristics to solve the problems of difficult water management and poor stability caused by salt deposition in traditional membrane reactors, ultimately achieving both high current density and stability in the electrocatalytic reduction of carbon dioxide. This enhances the carbon dioxide mass transfer process.

The invention relates to a filler device and a system thereof, comprising: a filler tower body having a gas outlet at the tower top and a gas inlet at the tower bottom; the random packing is filled at the upper end of the packed tower body and is positioned below the gas outlet; the structured packing is filled at the lower end of the packed tower body and is positioned above the gas inlet; wherein the random packing comprises a first group of random packing and a second group of random packing, the first group of random packing and the second group of random packing are the same in structure, and the first group of random packing and the second group of random packing are different in sequence. According to the packing device adopted by the invention, random packing is adopted at the upper part, regular packing is adopted at the lower part, and the two packing are combined, so that a solution flows downwards along a gap after entering the upper part of the packed tower body, carbonate is not easy to crystallize in the packed tower body, and the regular packing in the packed tower body also ensures the separation effect; and meanwhile, the air resistance is smaller, and the pressure loss of the packed tower body is improved.

The invention relates to an intelligent water and fertilizer precise drip irrigation regulation and control method for cotton in saline-alkali soil, and belongs to the technical field of precise agriculture. According to the method, accurate regulation and control of the whole growth cycle of the cotton are achieved through three-in-one technology integration of accurate seedling erecting and population construction, water and fertilizer integrated collaborative management and informatization intelligent decision making. The core technology comprises wide-narrow row precision seeding and density optimization configuration based on soil fertility difference, a dynamic fertilization strategy of'front control, middle promotion and rear supplement ', intelligent drip irrigation control based on soil moisture content and a crop water demand model, and a growth and development monitoring and decision support system based on multi-source information fusion (unmanned aerial vehicle remote sensing and ground Internet of Things). According to the method, the problems of low water and fertilizer utilization rate, unreasonable group structure and management link splitting in traditional cotton field management are solved, water can be saved by 30%-40%, fertilizer can be saved by 20%-30%, the boll forming rate can be increased by 15% or above, the fiber quality is remarkably improved, and economic benefits and ecological benefits are in synergistic interaction.
