aThe numbers in parentheses mean the proportion of carbon flows, namely, the flow value divided by the total carbon flow in the whole system. T i is the sum of flows put into the j-th compartment, and T j is for the sum flows into the j-th compartment analogously. The T i-T j intersecting number in bold indicates the total carbon flow of BDA.
