Exact(1)
From the basic equations of continuum mechanics in a three-dimensional (3D) isotropic and damped medium excited by harmonic body forces, exact expressions are obtained from quadratic variables for time-averaged energy quantities: kinetic- and strain-energy densities, structural intensity, structural intensity divergence and curl.

The intensity and divergence with respect to energy dependence for elliptical guide designs were compared with those for the linearly tapered and straight guides.
The images visualize the time histories of the eddies, the flame motion, the turbulence intensity, and streamline divergence.
High intensity and low divergence allows small gauge volumes to be defined in order to study stress fields existing over a range of several hundred microns.
These measurements have shown the existence of subwavelength beam that emerges from the microsphere with high intensity and low divergence where the beam keeps its subwavelength FWHM (full width at half maximum) over a distance given by (2 − 3) λ.
The results strongly support previous inferences of selection intensity based on divergence data, and suggest that nonessential genes with low expression are relatively likely to evolve under a nearly-neutral process.
In contrast, dfmr1 null NMJs showed a clear increase in Dlp expression intensity, with a divergence from control punctate expression towards a pattern that covers most of the bouton (Fig. 1A).
The structural intensity field and the divergence of structural intensity are evaluated.
The negative influence of astigmatism and defocusing on laser beam quality in far field is obvious and the astigmatism induces the non-axisymmetrical divergence of intensity distribution.
