校准是指为了使仪器与已有标准完全一致 （匹配）而将一个测量仪器与一个标准的或其他 已知准确度的仪器相比较的过程。
Unit 4
Calibration
The established standard is normally of at least four 1.3 times greater accuracy than the instrument being calibrated or the average of multiple standards if the four-times criterion is not feasible． 已有标准通常至少四倍于待校准仪器的准确度，或者 当四倍标准不可行时，则采用多重标准平均方式。 To say that an instrument is calibrated means that it 1.5 indicates measurements within specified limits of error for that instrument． 也就是说，仪器校准表明了其测量误差的确定限度。

5. Instrument and Control Products Contributing to Effective Operation of Water and Sewage Plants
Water and sewage systems are an important part of the social infrastructure and indispensable in people’s daily lives. A water system must provide safe water at a11 times. While a sewage system must purify sewage and rainwater collected by sewerage pipes and transform them into clear water before discharge into a river or ocean. At the same time, reduction of electricity consumption by water and sewage plants is important to reduce greenhouse gas emissions, which lead to global warming. It is also necessary to prevent overdosing of chemicals in treated water from the standpoint of environmental protection. In addition, the reduction of chemical consumption is important from the viewpoint of reducing the operating and maintenance costs of plants.

I n the case of a resistor ,the voltage-current relationship is given by Ohm's law,which states that the voltage across the resistor is equal to the current though the resistor multiplied by the value of the resistance就电阻来说，电压-电流的关系由欧姆定律决定。
欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。
The voltage across a pure inductor is defined by Faradav's law,which states that the voltage across the inductor is proportional to the rate of change with time of the current though the inductor.纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。
An Op-Amp is an integrated circuit that has many component parts such as resistors and transistors built into the device .设计运算放大器或Op-Amp的目的就是使他尽可能的减少对其内部参数的依赖性、最大程度地简化设计工作。
Each is measured with respect to ground potential.每一个电压均指的是相对于接零管脚的点位。
