1·All external walls are lightweight and insulated against heat transference in summer.
外墙都是轻量且在夏季绝热。
2·Hold No. 1 was on fire and timber stowed in it was burning fiercely. Obviously, fire spread was due to heat transference through bulkhead.
第一舱起火，舱内木材猛烈燃烧，火的蔓延显然是由于舱壁传热所致。
3·At present, the ventilation pipes are generally made by concrete or PVC without holes on the pipe walls, whose cooling effects are realized by airflow and heat transference.
目前的路基通风一般采用路基内预埋实体混凝土管或PVC管，管壁不能透风，主要通过管内空气流动和热传导方式达到冷却路基的目的。
