1. We've already mentioned the insulating effect of snow. 我们已经提到了雪的隔热效果。
2. Heat could be retained as debris fall back into impact craters, creating an insulating blanket. 当碎片落回撞击坑时，热量可以被保留下来，形成隔热层。
3. The snow, which blankets the ground in the winter, actually has an insulating effect on the soil beneath it. 冬天覆盖在地面的雪，实际上对下面的土壤有隔热作用。
4. During the winter, wet areas may provide an excellent insulating material in the form of cattail fluff and reeds. 在冬季，潮湿地区可以提供一种优良的、蒲草和芦苇形式的绝缘材料。
5. The insulating foam prevents ice from forming on the tank when it is filled with 500,000 gallons of supercold liquid hydrogen. 当容器内充满50万加仑的超冷液态氢时，绝缘泡沫可以防止冰在容器上形成。
