据《新科学家》杂志报道,英国伦敦皇家学院的燃烧物理学教授费利克斯·温伯格与他的同事设计了一种防止热量散失的新型炉圈,该炉圈呈倒圆台形,内层是耐火陶瓷材料,上面有螺旋状棱纹,炉圈底部即为普通的煤气炉盘。煮饭时,锅就放在炉圈内,锅底被 According to “New Scientist” magazine, Felix Weinberger, professor of combustion physics at the Royal College London, and his colleagues designed a new type of furnace ring that prevents heat loss. It is a refractory ceramic material with a spiral rib on it, and the bottom of the furnace ring is an ordinary gas stove. When cooking, the pot is placed in the oven and the bottom of the pot is
