By analyzing the rule of temperature distribution in seasonal frozen soil area, the function of temperature with time is established.

通过分析季节冻土区的温度分布规律，建立了温度随时间的变化函数。

Consequently, effective measures should be adopted to reduce the influence of thermal environment outside vehicles to ensure the uniformity and stability of temperature distribution in frozen cargoes.

因此建议采取有效措施减小车外热环境对货物温度场的影响，保证冷冻货物温度分布均匀、稳定。
