The results obtained show that the impulse corona stabilization and breakdown voltage depend on the SF_6 content and the wave- front duration,but are almost independent of the wavetail duration.

The wavefront aberrations of human eyes for 6mm pupil were measured with the Hartmann-Shack wave-front sensor,and Modulation Transfer Function(MTF) and Strehl ratio were computed from the wave-front aberrations.

Irradiated by a continuous wave (CW) DF laser with power of ～30 kW, wavelength of 3.8 μm, and irradiation time of 1 s, under the conditions of the laser beam approximately perpendicular to the coaxially rounded reflector, the thermal distortions of 3.8/0.633 μm dual-wavebands multi-layer high-power laser reflectors manufactured by different crafts are tested by a Shack-Hartmann wave-front sensor.

Using techniques from microlocal analysis, we study the problem of recovering the wavefront set of $\mbox{curl}(F)$ from that of the restricted Doppler transform of $F$.

In this paper, traveling wavefront solutions are established for two cooperative systems with time delay and non-local effects.

Conditions Causing Wavefront Instability in a Growing Colony of Bacterial Cells with Chemotactic Activity

A comparative analysis of the results of physical [1-4] and mathematical experiments [5-8] is used to elucidate the mechanism of additional pressure lift at a Mach wavefront.

A model of signal propagation is proposed that enables one to estimate this effect at signal wavefront durations much less than the propagation time.

A study is made of the velocity field induced by the motion of a thin wing and an incident pressure wave of finite extent with variable gas parameters behind the wave front.

On the possibility of compensating for small-scale wave-front distortions using a Zernicke cell and an optically controlled spat

The possibility of compensating for small-scale wave-front distortions using a spatial light modulator which is optically controlled by the output beam of a Zernicke interferometer was studied theoretically.

Implementation of the method is based on a series of eye aberration measurements taken at different angles to the optical axis by means of a wave-front sensor.

The AdS/CFT correspondence between conformal field theory and string states in an extended space-time has provided new insights into not only hadron spectra, but also their light-front wave functions.

This connection allows one to predict the form of the light-front wave functions of mesons and baryons, the fundamental entities which encode hadron properties and scattering amplitudes.

A number of applications of light-front wave functions are also discussed.

We discuss the relation between the two-nucleon Bethe-Salpeter amplitude and the light-front wave functions.

The wave functions found in this papor are required in the calculation of collision probabilities. The zero, first and second order phases of the wave functions are plotted against the k values for the incident electrons, the distortions are much greater in the field of the lithium atom than in the field of helium atom. The first and second order phases, which were practically negligible in the field of helium atom, are much greater in the field of lithium atom, and are comparable with the zero order phases at the higher velocities.

The diffracted field of a sound pulse source in a moving stratified medium, in which a shadow zone may be formed, has been studied theoretically. The fundamental equation is reduced to an inhomogeneous linear differential equation of second order by a mixed integral transform, and the solution is expanded into a series of normal modes. Following the method developed by Friedlander, asymptotic expressions of eigen value and eigen functions are derived from Langer's asymptotic solutions. The approximate formula of the field near the diffracted front is obtained for the observing points far inside the shadow boundary. Based on this formula, the establishing process and the attenuation with horizontal distance of field are discussed respectively. These relations are strongly dependent upon the boundary condition and the situations of source and receiver.

In this article a variational principle for three-dimensional transonic steady relative flow with embedded shock waves in a turbomachinery impeller of axial-, radialor mixed- flow type is developed. Its special feature is to take full advantage of the natural boundary conditions and 'the artificial internal boundaries' so as to facilitate the handling of the very complex boundary conditions of various kinds. As a result, all boundary conditions in the problem under study have been converted into natural ones....

In this article a variational principle for three-dimensional transonic steady relative flow with embedded shock waves in a turbomachinery impeller of axial-, radialor mixed- flow type is developed. Its special feature is to take full advantage of the natural boundary conditions and 'the artificial internal boundaries' so as to facilitate the handling of the very complex boundary conditions of various kinds. As a result, all boundary conditions in the problem under study have been converted into natural ones. Moreover, it is also shown that by taking variations of the position of the unknown flow discontinuities (such as shock waves, free trailing vortex sheets and other free stream surfaces) all matching conditions across these discontinuities, including the well-known Rankine-Hugoniot shock relation, can be derived from the variational principle as natural internal conditions.This article is primarily intended to provide, in cooperation with the discontinuous finite element [5], a theoretical foundation for developing a new computational method, which allows all flow field discontinuities to be captured out automatically and clearly (without smearing). Owing to the assumption of the existence of a velocity potential, the applicability of the present theory is limited to cases with Mach numbers before the shock not too larger than 1. The variational principle presented herein is a generalized one of those developed previously in [9].
