?：偏微分符號,?讀作round 法國人發(fā)明的.

偏導數(shù)英文翻譯為partial derivative,因此有時讀為partial.還有一種讀法,念成round

?：是希臘字母δ的古典寫法,數(shù)學里只用作表示偏導數(shù)的記號,在表示偏導數(shù)的時候,一般

不念字母名稱,中國人大多念作“偏”,(例如 z對x的偏導數(shù),念作“偏z偏x”.)

(簡單的把?y/?x讀成偏y比偏x)

倒三角符號“Nabla”,奈不拉,也可以讀作“Del”，讀nabla的居多，Del

▽讀

在某些英文書里會見到。nabla符號本身具有不同的功能，當它按不同的乘法規(guī)

則作用于函數(shù)時會分別得到

f’ f prime f撇

A上面一個橫杠：A bar

A上面一個星星*： A asterisk

A上面一個波浪線～：A tilde

A的厄米共軛（注意不是加號，那個豎比橫長）：A dagger（dagger：短劍，匕

首）

梯度：grandient 符號為grad，散度：divergence 符號為div。此時可直接讀

作grandient（divergence） of ...
