ZrSiO_4 bulk was prepared by pressureless sintering process and ZrSiO_4 coating was deposited on the SiC f/Si C substrate using air plasma method. The microstructures of ZrSiO_4 bulk and ZrSiO_4 coating are both dense. A preliminary study of a water vapor corrosion test for ZrSiO_4 bulk and ZrSiO_4 coating was performed under the conditions of 1.013×105 Pa, 90%H_2O/10%O_2, 1300 ℃, and low gas velocity. Results show that some pores appear on the surface of the ZrSiO_4 bulk. The main crystal phase is ZrO_2 and the weight loss of ZrSiO_4 bulk is only 0.236 mg/cm^2 after corrosion. The ZrSiO_4 coating peels off from the substrate after 109 h. The number and intensity of diffraction peaks of ZrO_2 in the coating increase, and the major crystal phase of the coating is still ZrSiO_4. A porous microstructure accompanied with cracks is observed on the surface of ZrSiO_4 coating after corrosion.

Based on the two-loop RGE of standard model gauge, top-Yukawa as well as scalar quartic couplings with full one-loop gravitational contributions in harmonic gauge, we study the constraints on the Higgs and top quark mass from the requirement that the other degenerate vacua at the Planck-dominated region exists. Our numerical calculations show that nature will not develop the other degenerate vacua at the Planck-dominated region with current Higgs and top quark masses. On the other hand, requiring the existence of the other degenerate vacua at the Planck-dominated region will constrain the Higgs and top mass to lie at approximately 130 and 174 Ge V, respectively.
