Somewhere in this cycle work must be done, which means that free energy must be expended. If the parts assemble themselves on a template spontaneously, work has to be done to take the replica off; or, if the replica comes off the template of its own accord, work must be done to put the parts on in the first place.

在这个循环的某个地方，必须做功，这意味着自由能必须被消耗。如果零件自发地在模板上组装起来，就必须做功才能把复制品取下来；或者，如果复制品自动从模板上脱落，首先一定要做功把这些零件装上。
