The results show that, Main crystallization phase of glass ceramic was hedenbergite, and the minor crystallization phases were augite and hypersthene. With increasing boron mud addition, the amount and the size of crystallization phases both gradually increased, the configure of crystallization phases transformed from the branch, the ball, to the block. The transformation from the branch to the ball could improve the properties of glass ceramic, and the transformation from the ball to the block could worsen the properties of glass ceramic.

It is proposed that the appearance of a new kind of mud additive can not represent the formation of a new mud system . The main influence factors of flow resistance at drill bit nozzle are solid content , particle size distribution and hydrophilicity of solid . It is not suitable to use high shear viscosity of both Casson rheology model and determined to predict drilling efficiency .

C Thermally controllable light valves:As described above, the clearing temperature of PDCLCs can be increased by UV-curing because of the reduction of impurity concentration. Therefore, when the texture of a CLC cell in the UV-cured region are changed to focal conic one, the scattering of light from the sample is maximum. However, the clearing temperature of PDCLCs can be increased continually with continually irradiating with UV light onto the sample, but the scattering is unchanged.

The results show that the zirconium sol has good spinnability when n: n= 1:3, reaction time is 6h and aging temperature is 15℃. The ZrO_2precursor fibers are made from hydrous zirconia chelated by acetylacetone. The sintercd fibers arecomposed of metastable tetragonal phase and sized about 15μm in diameter. Moreover, there aremany pores inside the fibers, but no cracks.4. ZrO_2/PVP hybrid fibers were prepared by blending the spinnable zirconium sol and 10 wt%PVP solution.
