随着温度升高,物质会从固态变成液态和气态。如果再进一步升高温度,就会有相当数量的中性粒子分离成正离子和电子,人们把这种正、负电荷大体相等的高温物质称为等离子体。高温等离子体受到约束后,能形成核聚变来获取能量。等离子体能产生范围很宽的电磁波,横跨微波、远红外、可见光、紫外和X射线。通过测定这些电磁波的性质,可以得到有关等离子体的信息。用光纤传感器取得等离子体的光谱参数,是一种新的手段,以提高谱线分析的空间和时间分辨能力。 As the temperature rises, matter changes from solid to liquid and gaseous. If you further increase the temperature, there will be a considerable number of neutral particles separated into positive ions and electrons, people put this positive and negative charge roughly equal to the high temperature material called plasma. High-temperature plasma is constrained, to form nuclear fusion to obtain energy. The plasma produces a wide range of electromagnetic waves across the microwave, far infrared, visible, ultraviolet and X-rays. By measuring the nature of these electromagnetic waves, you can get information about the plasma. Obtaining the spectral parameters of the plasma with optical fiber sensors is a new method to improve the spatial and temporal resolution of spectrum analysis.
