现代工程技术的发展,往往要求在复杂的工作条件下能单独地取得某一种感兴趣的参数的信息,而其他因素的影响则应尽可能地小;如在核爆炸过程中,在给定的观测点往往能感受冲击波、电磁辐射、振动和温度的影响,要获得某一参数的变化过程,则必需排除其他因素的影响。而作为检测工具的传感器来说,除了应具有对某一特定的参数的灵敏度,频率响应和动态范围等基本指标外,对外界环境的抗干扰能力是传感器设计和制造所面临的主要问
The development of modern engineering technology often requires that the information of a certain parameter of interest be obtained separately under complicated working conditions while the influence of other factors should be as small as possible. For example, in the process of nuclear explosion, Of the observation points can often feel the impact of shock waves, electromagnetic radiation, vibration and temperature, to obtain a parameter change process, you must rule out the influence of other factors. In addition to the sensitivity, frequency response and dynamic range of a particular parameter, the sensor as a detection tool, the anti-interference ability to the external environment is the main question facing the sensor design and manufacture
