We define a new rearrangement, called rearrangement by tamping, for non-negative measurable functions defined on ${\mathbb{R}}_{+}$. This rearrangement has many properties in common with the well-known Schwarz non-increasing rearrangement such as the Pólya–Szegő inequality. Contrary to the Schwarz rearrangement, the tamping also preserves the homogeneous Dirichlet boundary condition of a function.

夯实的功能：尺寸1的重新布置

我们定义了一种新的重排，称为夯实重排，用于定义在 ${\mathbb{[R}}_{+}$。这种重排具有许多与众所周知的Schwarz非递增重排（例如Pólya–Szegő不等式）相同的属性。与Schwarz重排相反，夯实还保留了函数的齐次Dirichlet边界条件。
