Adjustments
Adjusted the calculation method for ambient temperature so that the temperature drop is kept within a more reasonable range. The main change is that the temperature follows an S‑shaped decline curve over time. Over a survival period of 48 days, the temperature drops slowly in the early and late stages, while the decline is faster in the middle. The day‑night temperature difference gradually decreases as the days progress. The cooling effect caused by wind speed has also been significantly reduced.
