It is found from experiment that when pumped by skew light along the fibre's axis, both transverse electric wave and transverse magnetic wave exist in WGM lasing emission simultaneitly. With the increase of refractive index of cladding dye solution, the wavelength spacing between TE and TM waves of which the radial mode number and angular mode number are the same value decreases, and the central lasing wavelength of WGM bluely shifts to short wavelength direction.

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

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.
