英文释义
名词- the derivative of a function of two or more variables with respect to a single variable while the other variables are considered to be constant
同义词：partial
百科释义
In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary). Partial derivatives are used in vector calculus and differential geometry.
