上次转载的一篇文章提到金发姑娘原则: 自适应的“智能材料” -用于3D打印的颗粒操纵技术—金发姑娘原则 http://www.mogooto.com/forum.php?mod=viewthread&tid=1459&fromuid=3
那么什么是什么是金发姑娘原则或金发姑娘效应?它在3D打印中为什么会有应用前景呢?
我们先来了解一下什么是金发姑娘原则:
“金发姑娘原则”(Goldilocks principle)指出,凡事都必须有度,而不能超越极限。按照这一原则行事产生的效应就称为“金发姑娘效应”。
“金发姑娘原则”源自童话《金发姑娘和三只熊》的故事。金发姑娘发现了三只熊的房子,每只熊都有自己喜欢的食物和床。在挨个尝试过三只熊的食物和床后,金发姑娘发现有一个要么太大/太热,一个要么太小/太凉,只有一个是“刚刚好”。金发姑娘选择事物的原则被称作金发姑娘原则(Goldilocks principle)。
在天文学里,“金发姑娘地带”指的是一个星球周围的宜居地带。在经济学里,“金发姑娘经济”指的是维持适度增长和低通胀的经济。
The Goldilocks principle states that something must fall within certain margins, as opposed to reaching extremes. When the effects of the principle are observed, it is known as the Goldilocks effect.
The Goldilocks principle is derived from a children's story "The Three Bears" in which a little girl named Goldilocks finds a house owned by three bears. Each bear has their own preference of food and beds. After testing all three examples of both items, Goldilocks determines that one of them is always too much in one extreme (too hot or too large), one is too much in the opposite extreme (too cold or too small), and one is "just right".
In astrobiology, the Goldilocks zone refers to the habitable zone around a star. In economics, a Goldilocks economy sustains moderate economic growth and low inflation.
中国有句老话:“过犹不及。”大概能描述其中道理吧。
