integral characteristics meaning in English

[数] 积分特性

it is well-known that traditional acceleration transducers method has some default when measuring structural intensity . so, pvdf film, a new material of piezoelectrical macromolecule is brought up . according to its integral characteristic, particular shaped pvdf sensors are designed and the finite difference error in the result can be avoided by using them
针对以往主动控制研究中用加速度传感器测量结构声强时存在有限差分误差和附加振动这些不足，本文提出了一种新型的误差传感器?pvdf传感器，用它测量结构声强时不会产生有限差分误差和附加振动。
according to the integral characteristic of pvdf film, two pvdf sensors are designed to measure adjoint coefficient of sound radiation mode in this paper . based on the theory of sound radiation and two-dimensional modal sensors equation, and taking a simply supported plate as example, we measure mode l, mode 2 and mode 3 adjoint coefficient of its sound radiation by the sensors
本文是在声辐射模态理论以及两维分布式压电传感器方程的基础上，利用pvdf独特的积分特性，以简支矩形板为例，设计了pvdf压电薄膜传感器用于测量简支板第一、二、三阶声辐射模态伴随系数。
