按照早餐、午餐、晚餐能量摄入为30%、40%、30%的比例计算其一日三餐中能量的需求量：
the energy requirement from 3 meals daily is calculated by taking the energy absorption rate of breakfast,lunch and dinner at 30%,40% and 50% respectively.
能量理论需求量
energy theoretical requirement
按照三大产能营养素需求量（碳水化合物63%,脂肪25%,蛋白质12%）和实际需求量（吸收率按碳水化合物98%,脂肪95%,蛋白质92%）计算出具体能量需求如下：
Basing on the requirements of three energy producing nutrients namely carbohydrate63%,fat 25%,protein 12% and actual needs(absorption rate for carbohydrates,fat and protein are set at 98%,95% and 92% respectively),actual energy needs are caculated as follows:
各产能营养素理论需求量
theoretical needs for each energy producing nutrients
