∂：偏微分符号,∂读作round 法国人发明的.

偏导数英文翻译为partial derivative,因此有时读为partial.还有一种读法,念成round

∂：是希腊字母δ的古典写法,数学里只用作表示偏导数的记号,在表示偏导数的时候,一般

不念字母名称,中国人大多念作“偏”,(例如 z对x的偏导数,念作“偏z偏x”.)

(简单的把∂y/∂x读成偏y比偏x)

倒三角符号“Nabla”,奈不拉,也可以读作“Del”，读nabla的居多，Del

▽读

在某些英文书里会见到。nabla符号本身具有不同的功能，当它按不同的乘法规

则作用于函数时会分别得到

首）

梯度：grandient 符号为grad，散度：divergence 符号为div。此时可直接读

作grandient（divergence） of ...
