Phase-matched filter is applied to extract phase of fundamentalsurface wave, and then time-variable filter is used to correct amplitude spectrum in order to isolate fundamental mode signs.
From these studies, scientists have concluded that the surface of the primitive Earth was covered with oceans containing the molecules fundamental to life.

The IComponent interface is the fundamental contract between the design-time environment and an element to be hosted on a design surface (such as the Visual Studio forms designer).
IComponent 接口是设计时环境和要在设计图面（例如，Visual Studio 窗体设计器）上承载的元素之间的基本协定。
