查询词典 interference pattern

The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

Chapter 4 firstly analyses the generation mechanics, calculating method and interference effect of flow force in the outflowing large-capacity proportional valve. Then it not only presents a structural design to compensate the flow force according to the performance characteristic of the cone valve, but also calculates and simulates the flow field at the valve port through CFD software Fluent6.0. At last it studies the influence of compensation structure parameters and obtains better projected dimensions.
