We reveal that a maximum absolute bandgap for this structure is achieved for an intermediate rotation angle of the holes.

The calculated results obviously show that the crystal constructed from dielectric rods in the air background can generate a common band gap,which is called absolute photonic band gap,for both orthogonal polarization E and H.

0.618 method calculation on absolute maximum deflection on primary beam within bridge system composed of longitudinal and transverse beams;

Research on analytic solution of absolute maximum deflection of simply supported beam subjected to any finite moving loads;

The absolute maximum deflection was got by calculating the corresponding deflection.

By way of theory derivation, this paper defines the upper limit of the difference of absolute maximum moment of simple beam and the maximum moment in the section of span center, thus putting forward the valuable suggestion to design work.

Through theoretical deduition is determined a big difference between the absolute maximum moment of a simply supported beam and the maximum moment of the middle span section.

In the study of the extremum,the paper discusser the sampling distribution of sample absolute maximums for symmetrical continuous population,thus theorectically deriving statistics Ls distributed function of sample absolute maximums.
