If intermittent small scale breaking is occurring, the average energy density is limited by conditions near the long wave crests . 如果間歇性的小尺度破碎正在發(fā)生,平均能量密度就要受到長波波峰附近狀況的限制。
In a study published in the journal obesity reviews , they calculated the average energy density of menus at mcdonald ' s , kfc and burger king , using nutritional data from the fast food chains ' websites 《肥胖評論》雜志發(fā)表了他們的研究結果,他們通過快餐連鎖網(wǎng)站上的營養(yǎng)數(shù)據(jù)計算了麥當勞、肯德基和漢堡王食品的平均能量密度。
The average energy density of these restaurants ' meals was 263 calories per 100 grams , 65 per cent more than the density of the average british diet and more than twice that of a recommended healthy diet 這些快餐店食品的平均能量密度是每一百克263卡路里,比英國日常飲食的能量密度高出65 ,是推薦的健康飲食能量密度的兩倍多。
