关于测温的英文综述
英文回答:
Thermometry is the measurement of temperature. It is a fundamental science that has applications in various fields such as physics, chemistry, biology, and medicine. The
field of thermometry has evolved significantly over the centuries, with the development of new and more accurate methods for measuring temperature.
One of the earliest methods of thermometry was the use of a mercury thermometer. Mercury thermometers consist of a glass tube with a bulb at one end. The bulb is filled with mercury, which expands or contracts when the temperature changes. The expansion or contraction of the mercury can be measured on a scale to determine the temperature. Mercury thermometers are still widely used today, but they are being replaced by other types of thermometers, such as digital thermometers and infrared thermometers.
Digital thermometers use a thermistor to measure temperature. A thermistor is a semiconductor whose resistance changes with temperature. By measuring the resistance of the thermistor, the temperature can be determined. Digital thermometers are more accurate than mercury thermometers and they are also more convenient to use.
Infrared thermometers measure temperature by detecting the infrared radiation emitted by an object. The intensity of the infrared radiation is proportional to the temperature of the object. By measuring the intensity of the infrared radiation, the temperature can be determined. Infrared thermometers are non-contact thermometers, which means that they can measure the temperature of an object without touching it. This makes them ideal for measuring the temperature of objects that are difficult or dangerous to touch, such as electrical equipment or hot surfaces.
The field of thermometry is constantly evolving, with the development of new and more accurate methods for measuring temperature. These new methods are making it
possible to measure temperature with greater precision and accuracy than ever before.

测温。
测温是测量温度。
这是一项基础科学,在物理、化学、生物和
医学等各个领域都有应用。
测温领域在几个世纪以来有了显著发展,出现了测量温度的新型、更准确的方法。
测温最早的方法之一是使用水银温度计。
水银温度计由一个玻
璃管组成,一端有一个球泡。
球泡中注满水银,当温度变化时会膨
胀或收缩。
水银的膨胀或收缩可以在刻度上测量,以确定温度。
水
银温度计至今仍在广泛使用,但它们正在被其他类型的温度计(如
数字温度计和红外温度计)取代。
数字温度计使用热敏电阻测量温度。
热敏电阻是一种半导体,
其电阻会随温度变化而变化。
通过测量热敏电阻的电阻,可以确定
温度。
数字温度计比水银温度计更准确,而且也更方便使用。
红外温度计通过检测物体发出的红外辐射来测量温度。
红外辐
射的强度与物体的温度成正比。
通过测量红外辐射的强度,可以确
定温度。
红外温度计是非接触式温度计,这意味着它们可以测量物
体的温度而无需接触物体。
这使得它们非常适合测量难以或有危险
接触的物体,如电气设备或热表面。
测温领域在不断发展,出现了测量温度的新型、更准确的方法。
这些新方法使得比以往任何时候都更加精确和准确地测量温度成为
可能。
