by the pattern of sth

So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish. With experience, and with improved apparatus, 

it is now possible not only to locate a shoal but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo.


麻烦老师讲解一下惯用短语"by the pattern of sth"的含义和用法,查阅各种词典,没有找到解释和说明。


谢谢!

by the pattern of:by 表示“根据”;pattern 表示“模式;样式”。这个短语不是固定搭配,也不是很常用。

合在一起去理解,意为:“根据......的模式/样式/特征”。

It is now possible not only to locate a shoal but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo.

【翻译】现在不仅能够确定鱼群的位置,而且可以根据鱼群回声的特征辨别出是鲱鱼、鳕鱼还是其他大家熟悉的鱼。
