答
这个我也不懂 什么叫补充说明呀
不过你提的问题怎么高中知识就能解答 原文来自新概念4
答
of which的先行词是the principle。
the principle of which is similar是修饰radar的，补充说明作用
答
你的意思是：蝙蝠的回声定位能力经常与雷达相比,两者的原理也是相似的.思考了半天觉得这句话语法有问题,因为回声定位能力（ echo-location ）怎么能与雷达（radar）相比较应该是蝙蝠和雷达相比较吧.
答
先行词是the principle
the principle of which is similar是修饰radar的，构成非限制定语从句。可以参照定语从句的语法学习
