B-magnitude
3.The experimental sensitivity of the EMI-9815B and EMI-9850B are 10(-13) and 10(-15) magnitude,respectively,is agreed well with the calculational results by MCNP Monte-Carlo program.
4.We find that the decay width Γ? is of order 10(-14) GeV at most. We further estimate the branching ratios of li→ljγγ based on the current experimental constraints on li→lje+e-,and draw a conclusion that the constraint on B(μ→eγγ) is almost two orders of magnitude more stringent than the experimental one.
5.Accurate stellar trigonometric parallaxes may provide reliable data for studies on the physical properties and evolutional status of stars such as white dwarfs, red dwarfs, O and B stars, Herbig Ae and Be stars, and Ap and Am stars. Some fundamental parameters like absolute magnitude, effective temperature and radii of these stars and their positions in the HR diagram are of great importance in astronomical researches.
7.Therefore, their research has important actual meaning. This study has culvert A ,B and a set of models as experimental segments, and adopts EPS as reducing-load materials to research rigid culverts applied in civil engineering. Main research contents about culverts which have reducing-load measures or not, and have but different EPS thickness are as follows: magnitude and distribution of vertical soil pressure on the top of culverts and their change with fill height;
8.The applied DC voltage through the AFM tip polarized the ferroelectric domains in few milliseco nds while the applied AC voltage read them in nano-scale size as 60 nm. The dim ension of the nano-domains depends on certain parameters such as the magnitude and the duration of the applied voltage. Therefore, data storage of about 19.2 G b / cm2(120 Gb/in2) could be achieved.
9.The results mainly shows that for the plot of magnitude versus (log)cumulated frequency at a single source or a seismogenie fault—segment,the part of moderate and small size events still obeys G—R (Gutenberg—Richter) relation(exponent distribution) ,while the part of mainly size events is far away from the G—R relation curve of the moderate and small events, or does not obey exponent distribution or b value model.
