滞点是流体力学术语，是指流场中速度为零的点。从伯努利方程可以发现，流场中速度为零的点，静压最大，因此滞点的静压最大。该处的静压被称为滞止压强，温度被称为滞止温度。

In fluid dynamics, a stagnation point is a point in a flow field where the local velocity of the fluid is zero. Stagnation points exist at the surface of objects in the flow field, where the fluid is brought to rest by the object. The Bernoulli equation shows that the static pressure is highest when the velocity is zero and hence static pressure is at its maximum value at stagnation points. This static pressure is called the stagnation pressure.
