一、概述近年来,随着自动控制技术、地球物理学、生物学及气象学等门科学的发展,在增益、相移、振动等测量技术中对低颇振荡器的频带下限提出了新的要求.如近来发展的水底测量技术,一些测量生物电的仪器的运用与校准,尤其在自动控制技术中对伺服系统的测讲座讲座以及用普通热敏元件来稳定翰出振幅,就存在以一卜’王个缺点: 上{从专振藻援率降低,电阻R和电容C的数值将增大,C的加大使体积增加或不袒济;R的加大影
I. Overview In recent years, along with the development of automatic control technology, geophysics, biology and meteorology, etc., the lower limit of the low-frequency oscillator’s band is proposed in gain, phase shift and vibration measurement techniques Requirements, such as the recent development of underwater measurement techniques, the measurement and measurement of bioelectricity instruments and calibration, especially in the automatic control technology to test the lectures on the servo system and the use of ordinary thermal components to stabilize the amplitude of John out, there is a Bu ’Wang a disadvantage: {on the reduction from the rate of algae vibration algae, resistance R and capacitance C will increase the value of C to increase the volume to increase or not to economic; R increased shadow
