The nonlinear stability of three-dimensional disturbances for the Blasius boundary layers is studied. We adopted here the high accuracy method of using the expansions in orthogonal functions along the normal direction and the effective algebraic mapping to deal with the problem in the infinite region. The initial solutions of two-dimensional harmonic waves are given by Landau expansion, and the mean-flow-distortion is calculated by the approximation equation.

"Investiture," the word, signifies pretty much what we who have been to college or who belong to a fraternal order of one kind or another mean by "initiation"--the becoming something one was not before; the acquirement of a new status, with its rights and duties, together with the ritual by which this is acquired, and which symbolises what is acquired.

" Investiture ，"这个词，意味著什麼，我们非常谁已经上大学或谁属於一个兄弟以这种或那种意思"开始"-即成为一些人在此之前的获取一个新的地位，其权利和义务，连同仪式，其中，这是后天，这象徵著什麼是后天。

By means of the qualitative theory and method of delay differential equations, the weak conditions for the bound-edness of the system are obtained. By use of differential mean value theorem and computational techniques on delay differential equations, we show that the system is globally asymptotically stable under condition for the boundedness.
