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.

The results show that isobutene oligomerization is fast liquid-solid reaction. Under the temperature of 80 ℃~120 ℃ and pressure of 2.0 MPa, the products of oligomerization are mainly dimers and trimers of isobutene. The yield of trimers is higher than that of dimers and the mass fraction of trimers decreases with reaction temperature increasing. The yield of tetramers is much lower than that of dimmers and trimers. The tetramers are formed by reaction of isooctenes and C8 carbonium ion.
