填空题答案(国外英文资料) Fills up the topic Measurement is the measurement of the standard amount of the measured and the same property. According to the measurements obtained, the method can be divided into direct measurement, indirect measurement and combination measurement. According to the measurement of the obtained measurements, the measurement of deviation type, zero measurement and microdifferential measurement are classified. According to the measurement of the obtained measurements, different precision measurements and different precision measurements are available. 5. When using sensors measured, measured values compared with standard quantity directly, not need through computing the measured value, this measurement method is called direct measurement. The measurement is measured by the displacement of the instrument pointer, which is called a deviation measurement. 7. In the process of measuring influence and determine all factors to measure the size error always remains the same, the same to be measured repeatedly repeated measurement, called precision measurement, etc. Measurement errors are obtained by measuring the difference between the measured values and the measured values. 9. Measurement error has absolute error and practical relative error, reference, basic errors and the representation method for the additional error, etc. The closed-loop measurement system has two channels, one for the positive channel and one for the feedback channel. The measurement error is obtained by measuring the difference between the measured value and the measured value. The error can be divided into systematic errors, random errors and gross errors according to the rules and causes of the error in the measurement data. Normally sensors consist of measuring elements and conversion components. The basic features of the sensor include both static and dynamic features. The sensitivity of the sensor is the ratio of the output increment to the input increment corresponding to the o
