n.婴儿时代；婴儿；幼稚
The period from the War of Independence to the Civil War is the babyhood of the United States. 从独立战争到内战这个时期是美国的婴儿期。
Although this theory is in its babyhood, a new perspective of technological innovation has been introduced and this is just the aim of this paper. 理论虽显幼稚，但提供了一种新的看待技术创新的视角，这也是本文写作的目的所在。
