压力和频率的英文单词

压力和频率的英文单词
英文回答：
The terms "stress" and "frequency" are commonly used in various fields, including physics, electrical engineering, and signal processing.
Stress:
In physics, stress is a physical quantity that describes the internal forces that neighboring particles of a continuous material exert on each other. It is defined as the force per unit area and is typically measured in pascals (Pa). Stress can be either tensile (pulling force) or compressive (pushing force).
Frequency:
Frequency is a measure of how often a periodic event occurs. It is defined as the number of occurrences of an
event per unit time and is typically measured in hertz (Hz). Frequency is an important concept in various fields, such
as physics, electrical engineering, and signal processing.

应力。

应力是物理学中描述连续材料相邻粒子之间相互作用的内部力，定义为单位面积所受力，单位为帕斯卡（Pa）。

应力可以是拉应力（拉力）或压应力（压力）。

频率。

频率衡量周期性事件发生的次数，定义为单位时间内的事件发
生次数，单位为赫兹（Hz）。

频率在物理、电子工程、信号处理等
领域中是一个重要概念。
