The calculated value of stacking fault energy, 35 mJ/m(2) for 304 austenitic stainless steel, is in a good agreement with the experimental one, 30 mJ/m(2). In the present model we find that the Hirth's empirical relationship is also suitable for alloy.展开更多

This paper presents the piecewise semialgebraic set, which is the subset of Rn satisfying a boolean combination of multivariate spline equations and inequalities with real coefficients. Moreover, the stability under projection and the dimension of C^μ piecewise semialgebraic sets are also discussed.展开更多

The reaction rate was determined by monitoring the conductance change in solution with a liquid-purpose surface acoustic wave impedance sensor(SAW). The model was tested theoretically and experimentally with the mixture of methyl acetate and n-propyl acetate. The experimental detection limit of methyl acetate and n-propyl acetate (within 10 min) was 0.5 mu mol/L and 1.0 mu mol/L respectively and the recovery of the sensor system ranged from 93% to 106% (n=6).展开更多
