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。

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.
通过研究，我们提出了初步的NodD操纵子激活模型：第一，四聚体是NodD蛋白的功能单位，它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子；第二，小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体，在我们的模型中，NodD四聚体缩小其V形主体的弯折角，进而缩短其DNA结合功能域的间距；第三，小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用，NodD的构象改变由蛋白质经其双铆钉位点传递给DNA；第四，只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物；第五，不排除NodD与RNA聚合酶可能有直接的相互接触位点，不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物，但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。

chromophore：发色基
我们以此为目标,第一次成功地合成出一组可发射白光的粒子对,它包含了两个不互相作用的发色基(chromophore),可呈现激发状态分子内质子转移(excited-stateintramolecularprotontransfer).

imbibition：吸涨(作用)
吸涨作用(imbibition)是亲水胶体吸水膨胀的现象. 原生质、细胞壁和淀粉粒、蛋白质等都呈凝胶状态,其中细胞壁里面还有大大小小的缝隙. 水分子(液态的水或气态的水蒸气)会迅速地以扩散或毛细管作用跑到这些凝胶内部. 由于这些凝胶是亲水性的,

infiltration：下滲
实验证明,液态土壤水在非饱和状态下渗(infiltration) 亦称"入渗". 降水透过地面向下渗入土壤中的过程. 当雨水到达地面时首先补充土壤上层缺水,其余则向下渗透成为地下水. 是重力、阻力、分子吸力、毛管力. 惯性力和空气余压力综合作用的结果,

phase transition：相转移
改变绝热膨胀的气体压力,即会产生物质的相转移(phase transition),因此分子团会从「似液体」变成「似固体」的物质状态. 从实验的结果我们很清楚地知道,含氦的大分子团的相图中只存在「似液体」的物质状态. 至今人们对制备超流体分子团的可能性,

timbre：音
以听觉心理而言,即声音三个特征是:音的大小(Loudness),音高 (Pitch)与音(Timbre). ?以物理特性而言,声音是一种振动,或者说是一种质点如空气分子位移或速度的交替变化. 又或是空气密度一再重复地改变其疏密度的振动状态,
