The low environmental temperature is still mainly a controlling factor.
温度是其主要控制因子。
Nitrogen is the inert gases, low expansion coefficient, not easily with the environmental temperature rise for a long time, can maintain normal tire pressure, greatly reduce the flat tire.
氮气是惰性气体，膨胀系数低，不轻易随环境温度上升而上升，可较长时间维持正常胎压，大大降低爆胎几率。
Low temperature heating, based on the aesthetically integrated Concrete Core Activation (both used for heating and cooling), has an extremely low environmental impact.
低温加热，基于美观的综合混凝土核心(可用于加热和冷却)，对环境影响极低。
