between the x as static characteristic; When measuring over time and rapid change, the output y and the relationship between the x is called dynamic characteristics 第六章 1.输出信号稳态值与响应曲线在垂直方向的差值为系统的动态误差。它与时间 t 有关，当 t 时，动态误差趋于零。显然，在相同时刻，输出与输入之间的差异也越小，所以应尽可能采 用时间常数τ 值小的测试系统。 翻译： Signal output steady-state value and response curve in the vertical direction of the difference for the system dynamic error. It and time t relevant, when t, the dynamic error tends to zero. Obviously, at the same time, the difference between the input and output and the small, so should as far as possible the time constant τ value small test system. 2.实际的测量系统往往难以做到完全符合不失真测试条件， 被测信号也不可能包含所有的频 率分量。根据测试精度的要求，只要被测信号的率带宽度处于测试的带宽。 翻译：The actual measurement system is often difficult to do fully comply with no distortion test conditions, the measured signal can't contain all of the frequency component. According to the test accuracy requirements, as long as the measured signal rate band width in the bandwidth of the test. 第七章 1.电阻应变式测力传感器是目前使用最广泛的一种测力传感器。它不仅灵敏度高，而且可用 于测量力的瞬时值， 另外， 还可以应用合理应变片的位置及接桥方式消除切削分力的相互干 扰，从而使其结构简化。 翻译：Resistance strain type force transducer is currently the most widely used a force transducer. It not only high sensitivity, and can be used for measuring force instantaneous value, in addition, also can be used reasonable strain gauge position and the bridge cutting force way to eliminate the mutual interference, so that the structure simplification. 2.半导体应变片的突出优点是：灵敏度高，可测微小应变。其不足之处是：电阻温度系数大， 对环境温度的变化敏感；测量大应变时灵敏度的非线性严重。 翻译：Semiconductor strain gauge outstanding advantage is: high sensitivity, measurable small strain. The deficiency is: temperature coefficient of resistance to the environment, the change of the temperature sensitive; When measuring large strain sensitivity of nonlinear serious. 第八章 1.电感式传感器的应用十分广泛，凡是与位移有关的物理量都可通过它转换成电量输出。常 用来测量振动、厚度、应变、压力、加速度等各种物理量。 翻译：Inductive sensor used widely, all and displacement related physical quantities can be converted into electricity output through it. Commonly used to measure vibration, thickness, strain, stress, acceleration, etc. Various kinds of physical quantity. 2.根据电容式传感器的原理，利用极间距和极板遮盖面积的变化，可以测量直线位移或角位 移。通过弹性膜片可以测量压力，通过弹性梁可测量振动和加速度等。 翻译：According to the principle of the capacitive sensor, using pole spacing and plate cover area change, can measure linear displacement or angular displacement. Through the elastic diaphragm can measure pressure, through the elastic beam can be used to measure the vibration and acceleration, etc.
