According to the data of preliminary survey, the authors established a landslide geological model,on the basis of analyses on the sensitivity of landslide, tried to simulate and calculate the landslide stability of Shuitianba with the method of transfer coefficient when it is under different strength parameters, and study the landslide mechanism. The results show that it is sensitive to the effects of shear strength parameters of sliding zone and groundwater level on landslide stability safety coefficient, which provides reliable basis for calculation of landslide stability. 展开更多

Poly(ethylene glycol)-modified 13-diketone macroligand is developed to sensitize europium(III) ions in water. High lumines cence intensity characteristic of Eu3 was achieved due to spontaneous formation of micelle-like structure in which the hydro phobic core prevents luminescence-quenching by water molecules. The pH is found to induce a quantitative ratio change in two fluorescence bands from both ligand and Eu3. 展开更多
