1Quantity of substance
If a mixing fluid includes a fluid in gas phase and a fluid in liquid phase with great difference in mass, then the fluid mixture can be formed, but it is difficult to homogeneously mix the two fluids in a short time due to difference on specific gravity
Solution Approach 1:
The patent applies parameter changes by transforming the physical state of the fluids from gas-liquid phases to supercritical phase through temperature and pressure adjustments. This phase transition eliminates the specific gravity difference between gases and liquids, enabling homogeneous mixing that was previously unachievable in short time periods.
Solution Approach 2:
The invention utilizes phase transitions by converting both the gas phase fluid and liquid phase fluid into supercritical fluids. This phase transition allows the fluids to mix homogeneously in the supercritical state, resolving the mixing difficulty caused by specific gravity differences in conventional gas-liquid mixtures.
2Ease of manufacture
If heterogeneous-phase mixing fluid is used for surface treatment of resistive memory, then the treatment can be conducted, but the resistive memory presents characteristics with local differences, adversely affecting electrical property and performance
Solution Approach 1:
The patent changes the physical parameters (temperature and pressure) to achieve supercritical phase, which enables homogeneous mixing of the fluids. This homogeneous mixture ensures uniform surface treatment across the resistive memory, eliminating local differences and improving manufacturing precision while maintaining processability.
Solution Approach 2:
The invention utilizes supercritical fluid dynamics to achieve homogeneous phase mixing and uniform distribution during surface treatment. The supercritical fluid properties enable penetration and uniform action across the resistive memory surface, ensuring consistent electrical properties and performance.

AI summary
A reaction method with a homogeneous-phase supercritical fluid includes introducing a first fluid into a mixing chamber. A mass is less than or equal to that can be absorbed by the molecular sieve component, totally absorbing the first fluid by the molecular sieve component. A second fluid is introduced into the mixing chamber with a mass being greater than that can be absorbed by the molecular sieve component. A temperature and a pressure in the mixing chamber are adjusted to a critical temperature and a critical pressure of the second fluid, respectively, releasing the first fluid in supercritical phase from the molecular sieve component into the mixing chamber, followed by homogeneously mixing with the second fluid in supercritical phase in the mixing chamber to obtain a homogeneous-phase mixing fluid. The homogeneous-phase mixing fluid is then introduced into a reaction chamber connected to the mixing chamber.
