At first the energy of the microwave will energized the argon to be ionization, and the generated heat make the sulfur volatilizing into bivalency sulfur or dipolymer sulfur high pressure steam. The molecule transition will happen under the microwave energization, and the visible light will be emitted when the sulfur states change into the low energy level. The spectra of the plasma lamp is nearly centering at the visible lights, and there are very little ultraviolet and infrared spectrum, the Fig 3 shows the spectra of the sun and the plasma lamp from which we can see the spectrum character clearly.

微波能量首先激励氩气使其电离，产生的热量使硫挥发成为二价硫分子或二聚物高压蒸汽，在微能量的激励下使它形成分子跃迁，当返回到较低能级的状态时以连续光谱的形式放射出光线，它的光谱基本上集中在可见光，红外线和紫外线的辐射量很少，（图3）硫的放射光谱和太阳光谱的比较图片，可以很清晰地表达这一特性。

Quantum dots are a kind of semiconductor nanopaticles with the radius equal to or less than the exciton Bohr radius. They have tremendous potential in the field of biology and medicine because of their unique and tunable optical properties (broad excitation spectrum, narrow emission spectrum, precise tunability of their emission peak and negligible bleaching, etc) as new fluoresent probes.

量子点是半径小于或接近于激子玻尔半径的一类半导体纳米晶，作为一种新型的荧光标记物，其独特和可调谐的光学特性（宽的激发光谱、窄的发射光谱、可精确调谐的发射波长以及可忽略的光漂白等）使其在生物和医学方面显示出巨大的应用潜力。

For different substances that occur under two different light sources in two different stripes, when the slit mouth gradually Masuda Otsuki reduced, this process will find in the thin section of a gas light appears under the of the color overlay each other like , so that spectra of surface light intensity gradually weakened and finally win only the lower part of the spectrum not being added to the surface occurs, known as:"Bright-Line Spectrum."

对于不同物质在两种不同光源下出现的两种不同条纹，当把狭缝口逐渐増大即缩小，这一过程会发现在稀薄气体光源下出现一段一段的各单色象相互叠加，从而使谱面中光强逐渐减弱，最后只胜下部分沒被叠加到的谱面出现，被称为："明线光谱"。
