一种积分变换，它来源于函数的傅里叶积分表示。积分 （1） 称为? 的傅里叶积分。周期函数在一定条件下可以展成傅里叶级数，而在（－∞，∞）上定义的非周期函数?，显然不能用三角级数来表示。但是J.-B.-J.傅里叶建议把?表示成所谓傅里叶积分的方法。(An integral transformation derived from the Fourier integral representation of functions. The integral (1) is called the twin Fourier integral. The periodic function can be extended to Fourier series under certain conditions, while the non-periodic function twin defined on (-, u) obviously cannot be expressed by trigonometric series. But J. -B. -J. Fourier suggested that twins be represented as so-called Fourier integrals.)

C++开发的。农夫过河。一个农夫带着一只狼，一只羊和一些菜过河。河边只有一条一船，由 于船太小，只能装下农夫和他的一样东西。在无人看管的情况下，狼要吃羊，羊要吃菜，请问农夫如何才能使三样东西平安过河。 -C development. Farmers across the river. A farmer with a wolf, a goat and some vegetables across the river. Only a river boat, the boat is too small to install under the farmer and his thing. Unattended circumstances, the wolf to Qiyang, the sheep to the meal, ask the farmers how to make three things safely across the river.
