The combination of "扩压叶栅" (expansion pressure blade), compressor, and cascade is a crucial aspect of aerodynamics and mechanical engineering. This intricate system plays a vital role in the operation of turbines and other fluid dynamic machinery. In this context, the term "扩压叶栅" refers to the expansion pressure blade used in turbines, while the compressor is responsible for increasing the pressure of the incoming air or gas. The cascade involves a series of airfoils arranged in a particular pattern to control fluid flow. Together, these components work in harmony to optimize the efficiency and performance of various types of machinery. English short sentences and example sentences related to these components provide a comprehensive understanding of their applications and importance in engineering and aerodynamics.

冲击波超压与动压
[解释]：核爆炸产生的高温、高压火球膨胀，在周围介质中形成连续向外传播的压力脉冲（或冲击波），冲击波阵面传播到空间某点时，超过周围环境大器的压力称超压；空气粒子高速随波阵面运动产生的冲击压力称动压。超压和动压都以帕斯卡（Ｐａ）为主单位。超压随时间的变化取决于爆炸威力、距爆点的距离和爆心周围的介质情况。特定地点的峰值超压一般出现在冲击波阵面到达该点的瞬间，超压在该点的持续时间称为正压作用时间。尔后，该点的压力下降到低于周围压力，称为负压，再逐渐回升到周围压力值。对人员的直接冲击伤，超压为２０—２９千帕可引器轻度伤；２９—５９千帕可导致中度伤；５９—９８千帕可造成重度伤；大于９８千帕可造成极重度伤。动压为１０—２０千帕可造成中度伤；２０—３９千帕可造成重度伤；大于３９千帕可造成极重度伤。动压的推动、抛掷和超压的挤压会造成物体变形和毁坏。
