For example, a great deal of research for many years has been carried out at home and abroad on taking hydrogen-rich water as a high-efficiency antioxidant aqueous solution, and the hydrogen-rich water has special strong antioxidant capacity, can selectively neutralize hydroxyl radicals, nitrite anions and the like, and is applied to the fields of life, bioscience, industrial chemistry and the like; for example, oxygen-enriched water is applied in a plurality of industries, particularly the water body culture industry improves dissolved oxygen and the water body purification treatment improves DO value; and for example, the nitrogen-rich water has ideal sterilization and deoxidation effects, and can be well applied to animal and plant preservation, agricultural cultivation and the like to obtain good effects. It is known that the solubility of a gas in a pure water body is certain, and the solubility varies according to the properties of the gas, the pressure and the temperature of a solvent. For example, at 20 ℃ the pressure of the gas is 1.013X 10^5Pa, and one liter of water can dissolve the gas in a volume of 0.01819L for hydrogen and 0.03102L for oxygen. While the gas density of nitrogen in the standard case is 1.25g/L, the solubility of nitrogen in water is small, and only about 0.02 volume of nitrogen is dissolved in 1 volume of water at normal temperature and pressure, and so on. Increasing the solubility of the gas or the content of the gas in the aqueous solution has a more specific effect and a wider range of applications for various fields. How to increase the concentration of high concentration aqueous solutions of various gases has been the subject of intense research.

The geometrical size relationship of the jet cavitation micro-reactor (monomer) in FIG. 6a iswhen entering ═ iAnd then the mixture is discharged out of the furnace,middle ═ e (1/3-1/5)L1 ═ 1/3L₀. The curve chart of the relation among the P pressure, the V flow velocity and the pipe diameter change can be obtained as follows: when the pipe diameter is contracted to L0 in the L1 interval, the fluid pressure is gradually reduced, the flow rate is gradually increased, when the pipe diameter is contracted to L0, the flow rate is maximum, the fluid pressure is minimum, and due to the inertia effect, the fluid pressure instantly generates a negative pressure phenomenon, so that the fluid cavitation effect is generated. At this time, the nuclei of the microbubbles in the liquid are generated and grow until they collapse, and a large amount of energy is generated. When liquid passes through the monomer microreactor I, liquid cavitation is generated, when monomers II are combined, jet cavitation effect is generated, and the dual cavitation effect generates a series of effects such as mechanical effect, thermal effect, chemistry and biology. Mainly represented by the increase of heterogeneous reaction interface; the high temperature and high pressure generated in the microbubble process causes decomposition of macromolecules, breaking of chemical bonds, generation of free radicals and the like.
