major axis
At the phase plane "the longitude of the subsatellite point-semi-major axis" the regions of migration of separatrices where the separatrices can move due to the influence of perturbations are isolated.
      
The dimensions of these regions and the distances between them have the same order of magnitude, several kilometers along the semi-major axis.
      
Flow past an oblate ellipsoid of revolution aligned along the major axis
      
We found no evidence of gas rotation around the major axis of NGC 6286, which argues against the assumption that this galaxy has a forming polar ring.
      
We found no significant deviations from the circular rotation of the galactic disk in the velocity field in the regions of brightness excess along the major axis of the galaxy (the putative polar ring).
      
The second type is characterized by a quantum number corresponding to the motion of carriers along the major axis of the ellipsoid.
      
The relaxation time spectra are calculated as well as the frequency dependences of the dielectric loss factor of the embedded particles that possess a permanent dipole moment directed along the major axis of each rod.
      
While along the major axis direction, the synthetic jet contracts firstly and then spreads slowly.
      
Both the residual current and the major axes of all tidal constituents were nearly perpendicular to the isobaths and the tidal current ellipses rotated clockwise; the major axis of the major tidal ellipse was about 3 cm s-1.
      
SOM, determined through sequential reduced major axis regressions of BL, RL, relative rostral length (RRL = RL/CL), and BW against CL, was 23-24 mm CL in females and 21-22 mm CL in males.
      
The isoseismals are generally in elliptic shape with major axis trending near N-S direction.
      
Critical aspect ratio of the specimen is about 3:2, and critical ratio of distance between the tip of the hole and the border of specimen (d) to the major axis of the elliptic hole (l) is about 7.3.
      
And then the seismic intensity attenuation relations along major axis, minor axis and mean axis are established separately.
      
The approximation may lead to unrealistic results expecially when considering transverse oscillations of the beam parallel to the ellipse major axis.
      
Maximizing a precessional figure of merit based upon the observational techniques of planetary astronomy leads to the optimal orbital condition that the ratio of the semi-major axis to the semi-minor axis of the elliptical orbit is equal to √3.
      
Various options for the definition of semi-major axis, from the viewpoint of satellite dynamics, are described.
      
The largest elliptic oscillation is the semi-annual wobble with a maximum semi-major axis of up to 13 mas (milliarc seconds).
      
Let Qa,h be a convex region of the plane whose boundary consists of two semiellipses joined by two (straight) lines parallel to the major axis of the semiellipses (elliptical stadium).
      
Each excitatory region usually had an elliptical or rectangular shape with its major axis parallel or nearly parallel to the horizontal meridian of the visual field.
      
Cone and rod centres were usually elliptical, and in almost 60% of cells the major axis through the receptive field centre was oriented within ±20 ° of horizontal.
