How Termite Mounds Maintain Stable Internal Temperatures Year-Round
白蚁丘如何全年维持内部恒定温度
-
Termite mounds use passive ventilation systems shaped like porous chimneys to draw cool air from underground tunnels.白蚁丘利用形似多孔烟囱的被动通风系统，从地下隧道中抽取凉爽空气。
-
Solar heat warms the outer walls each morning, creating convection currents that circulate air through internal shafts.晨间太阳热量加热外墙，形成对流气流，使空气在内部竖井中循环。
-
Nest chambers sit deep inside where humidity and temperature stay nearly constant despite desert extremes.巢室深藏于内部，湿度与温度几乎恒定，不受沙漠极端气候影响。
-
Architectural features like north-facing ridges and thermal mass materials act like natural thermostats without energy input.朝北的脊线和蓄热材料等建筑特征，无需能耗即可发挥天然恒温器作用。
-
Infrared imaging shows surface temperatures fluctuate widely while core zones vary by less than two degrees Celsius.红外成像显示表面温度波动剧烈，而核心区域温差却不足2摄氏度。
