2.SPACE-INVARIANT AND ROTATION-INVARIANT IN A GIVEN ANGLE RANGE PATTERN RECOGNITION AND THEIR FILTER DESIGN
4.For molecules H2O and NH3 are found the reduction matrices which can reduce their Cartesian coordinates (induding translation and rotation coordinates), the mapping of the reduction matrices to normally ordered unitary operators in Hilbert space is obtained by virtue of the technique of integration within an ordered product of operators which turns out to be the resultant transformation of rotation and squeezing
5.This paper proposes a new method to measure the 2 D beam transverse phase space with computerized tomography (CT) technique and Cerenkov radiation "double imaging method". The usual method with CT technique entirely depends on the quadrupole scanning and can not get a full π Radon rotation angle, which is essential to the Radon transform, the mathematic fundamental of CT technique.
8.The authors compare the theoretical values predicted by two anelastic models with the recently observed ones of tides and the Earth rotation variations at M 2, M f, M m, Chandler wobble and 18.6 year frequencies. The response of mantle anelasticity at different frequencies is analyzed, and the observed results of space geodesy are used to constrain the theoretical models of anelasticity.
