Abstract: In this paper,Maxwell's speed distribution function is derivated by using the character of three-di- mensional sphere and the relation between the Maxwell's velocity distribution and the Maxwell's speed distribution without solving any partial differential equations.

Key words: Maxwell speed distribution function, character of three-dimension sphere
