(9) using three-dimensional ocean gas hydrates scene as a system, it is input to the VR one for supporting eyeball interaction
Immersion experience is carried out in machine.
Step described in this programme (3) in the specific implementation, in the following ways:
If gas hydrates preservation section model is a cylindrical body, as shown in Fig. 2 (1), sea level is reduced to a water
Plane, the as upper top surface of cylindrical body, the relative dimensional rectangular coordinate system established are different from the three-dimensional in virtual reality scenario
Coordinate system, using the center of circle of top surface on cylindrical body as coordinate origin, X-axis positive direction be east, Y-axis positive direction be north, Z axis perpendicular to

Body.
This programme is according to the stable theory formula that balances each other: 1/T=3.79 × 10-3-2.83×10-4LgP, wherein T is temperature
Degree/K, P is pressure/MPa, to tell about natural gas hydrate phase balance emulation curve, natural gas hydrate phase balance emulation curve such as Fig. 3 institute
Show, gas hydrates phase boundray curve and the water temperature gradient curve of hypothesis, geothermal gradient region enclosed by a curve △ in Fig. 3
OBC is exactly the region that pressure and temp condition is suitable for gas hydrates formation.Again because of gas hydrates in the seawater
Density will be lower than density of sea water, the region △ ABC within the scope of seawater, so this region formed gas hydrates will on
It is floating, and dissolve since temperature raises.Therefore remove the region △ ABC in the region △ OBC, i.e. the region △ ABO is the day to be formed
The stabilized zone of right gas compound；Natural gas hydrate phase balance emulation is calculated by the conversion of the depth of water and pressure, geothermal gradient
Boundary, it is current to observe if Fig. 3 gradually judges under current pressure and temperature (or depth and temperature) using phase equilibrium line as standard
The physical state of gas hydrates at point, to obtain natural gas hydrate stability zone information.
In fact, since ocean temperature has day, the moon, year, the variation of many years quasi-periodic and irregular variation, mainly by latitude
Degree, ocean current, season, effect of depth, show through directly observing: ocean temperature diurnal variation very little, change depth of water range from 0~30 meter
Place, and changing reachable 350 meters or so places of the depth of water year has a thermostat layer at 350 meters of the depth of water or so places.Three big oceans-the Pacific Ocean, the Atlantic Ocean and the Indian Ocean surface year is flat
Equal water temperature is about 17.4 DEG C, wherein, up to 19.1 DEG C, the Indian Ocean is taken second place with Pacific Ocean highest, up to 17.0 DEG C, the Atlantic Ocean is minimum, is
16.9℃.Water temperature generally reduces (every 1000 meters of the decline of depth, temperature about declines 1 °~2 DEG C) with the increase of depth, in depth
Water temperature at 1000 meters is about that be deeper than at 4~5 DEG C, 2000 meters for 2~3 DEG C be 1~2 DEG C 3000 meters at, so in the present embodiment
Ocean temperature field data can derive from the observation data in practical sea area, the ocean temperature lattice point that can also be issued using atmosphere
Data construct ocean temperature field model using certain interpolation algorithm, for example, using multiple quadratic form interpolation method etc..
The Operational Mechanisms that this programme adjusts natural gas hydrate phase balance emulation curve as scene dynamics, being capable of actual response
The state of gas hydrates under the present circumstances, thus intuitively, the visual expression stable mechanism of ocean gas hydrate；
Be driving with eyeball tracking, by marine environment large scene and the small scene of gas hydrates triphase flow organically combine and from
It adapts to, the more details of gas hydrates is understood convenient for observer；This method is easy to spread, can be according to different sea area seawater
Depth and the hydrate preservation amount in the sea area establish the threedimensional model of different spaces size, to express the hydrate three-phase of this area
Actual conditions can be widely used for different sea area gas hydrates three-phase experimental analyses and teaching field, for natural gas moisture
Solution is of great significance with synthesis process simulation, recovery process simulation, education, science popularization.
The above described is only a preferred embodiment of the present invention, being not that the invention has other forms of limitations, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
It imitates embodiment and is applied to other fields, but without departing from the technical solutions of the present invention, according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling to the above embodiments, still fall within the protection scope of technical solution of the present invention.

Are as follows:
Wherein, t=f (x, 0, z), f (x, 0, z) are ocean temperature field model, and 0 represents solid, and 1 represents gas, and 2 represent liquid.
