The sparse distribution of the feathers, however, also allows considerable lateral air movement over the skin surface, thereby permitting further heat loss by convection.
然而，羽毛的稀疏分布也使得皮肤表面形成相当大量的侧向空气流动，从而可以通过对流进一步散热。
The calculated results show that the natural convection shouldn′t be neglected for molten steel flowing in tundish because of heat loss.
计算结果表明，高温钢水在中间包内流动时，不能忽略自然对流流动；
The receiver with a vacuum tube can greatly reduce the heat loss caused by surface convection, and hence the heat transfer efficiency can be improved effectively.
而太阳能集热器用真空管作为接收器，可以大大减小接收器外表面的散热损失，可以显著提高集热器的集热效率。
