Summary:The utility model relates to a blade and a fan. The blade (10) comprises: a low-pressure side surface (12) and a high-pressure side surface (14); a plurality of fluid channels (30) extending from the high-pressure side surface (14) to the low-pressure side surface (12) through the thickness of the blade (10); and a moving body (20) movably provided in the blade (10) and adapted to move in accordance with a rotational speed of the blade (10) during rotation of the blade (10) to change an opening degree of the plurality of fluid passages (30). According to the blade, the performance of the fan can be remarkably improved. 本公开涉及一种叶片和风扇。叶片(10)包括：低压侧表面(12)和高压侧表面(14)；多个流体通道(30)，从高压侧表面(14)贯通叶片(10)的厚度而延伸至低压侧表面(12)；以及移动体(20)，被可移动地设置在叶片(10)中并且适于在叶片(10)旋转期间根据叶片(10)的旋转速度而移动以改变多个流体通道(30)的开度。根据本公开的叶片，可以显著提高风扇的性能。
