Conditions for plasma-coupled temperature fields：
- A 4KV electric field strength to ground is applied within the effective area of the cabinet
- The effective area of the cabinet meet the temperature range of (-4.5, -3.5)℃
The phenomenon of bottled water in the cabinet：
- In environments ranging from -4.5°C to 3.5°C, the appearance of rosebuds changed over time in both exposed containers and sealed containers.
- In environments ranging from -4.5°C to 3.5°C, the scent of rosebuds changed over time in both unopened containers and sealed containers.
Real-time photo recording:
| Rose buds collected on April 23, 2026 |
| Photos taken on April 24, 2026, showing rose buds being stored at room temperature, one inside an airtight container and the other sealed. |
| Photos taken on April 25, 2026, showing rosebuds stored in airtight and sealed containers for 24 hours. The exposed buds showed a reduced odor, while the sealed buds showed no significant change. |
| Photos taken on April 26, 2026, showing rosebuds stored in exposed and sealed containers for 24 hours. The exposed buds had very little odor, while the sealed buds showed no significant change. |
| Photos taken on April 27, 2026, showing rosebuds stored in exposed and sealed containers for 24 hours. The exposed parts had no odor, while the sealed parts showed no obvious changes. |
| Photos taken on April 29, 2026, showing rosebuds stored in exposed and sealed containers for 24 hours. The exposed parts had no odor, while the sealed parts showed no obvious changes. |
Summary of the 5-day experiment:
- Ignoring the influence of lighting on the photos, the degree of opening of the closed flower buds of Luo Louyu remained unchanged to the naked eye.
- In terms of color and visual effect, the closed parts were significantly better than the exposed parts.
- In terms of smell, the closed parts were significantly better than the exposed parts.
