The main loop then looks through its internal mapping table between its signals and handlers, also called callbacks, and calls the handlers registered for the given signal on the given object.

然后主循环查询自己的信号和处理程序之间的内部映射表，也叫做回调，并调用注册到指定对象的指定信号的处理程序。

At the same time, it introduces the definition of spatial distance, and establishes a multi-point to one point optimal signal detection theory according to the relationship of modulation mapping.

同时引入空间距离的概念，根据调制映射关系，建立起多对一的最优信号检测理论。

Starting from FIR signal theory a mathematical model for the optical FIR filter is established, and the mapping relation between the model and FIR filter is analyzed.

从FIR信号理论出发，建立了光学FIR滤波器数学模型，并分析了它与FIR滤波器的映射关系。

SKA. By mapping the signal's variations across the sky, astronomers might be able to determine the extent of clustering of matter in the universe's earliest days.
