The third chapter introduces the construction of the reflection target system of the core competition, and analyzes the essentiality using the AHP.

第三章主要介绍通信设备制作业评价指标体系的搭建，并运用层次分析法确定指标权重。

In this process of transmission and reflection, the sounds are changed, and the changes in the echoes enable the bat to perceive features of the target.

在这个传递和反射的过程中，声音发生了变化，回声的变化使蝙蝠能够感知到目标的特征。

The basic approach here is to construct a custom class at runtime that will wrap access to the target classes (previously reached by reflection) in a way that can be used by your general-purpose code.

这里的基本方法是，在运行时，以一种可以被一般性代码使用的方式，构建一个自定义的类，其中将包装对目标类的访问(以前是通过反射达到的)。

Like its cousins radar and sonar, lidar (light detection and ranging), works by broadcasting electromagnetic waves towards a target and then building up a picture from the reflection.
