0 a type of curve such as that made by an object that is thrown up in the air and falls to the ground in a different place -- 拋物線
Here we restrict ourselves to quantify the strength of the thermal lensing and hence fit a parabola to the refractive index profiles.
It was prepared in order to determine the degree of elevation for parabolas of various heights but with the same width of 465.
The procedure was applied to the 3 m focal length off-axis parabola.
The positions are represented after pattern recognition by matching experimental parabolas to the theoretical ones.
Above the gain 8, the volume ignition happens, as seen from the highly deformed dashed parabolas for these higher gains.
The parabolas are labelled: inside by the time and outside by the values of 1 and 2 when finite.
Neither a straight line nor a parabola can be fitted reasonably to these data.
Furthermore, saddle connections can occur along invariant lines of (13), corresponding to invariant parabolas of (11).
