In the spectra of the alkali metals each line of the trunk is a doublet, and we may speak of a twin trunk springing out of the same root.
Young, according to which the dark line observed in the centre of each component of the sodium doublet in a Bunsen burner is transparent to a radiation placed behind.
Tretis, or treitis, is a doublet of "treaty," which also meant a discourse or account.
A doublet is any class which possesses a member x such that the modified class formed by all the other members except x is a unit class.
He described the reflecting goniometer in 1809 and the camera lucida in 1812, provided microscopists with the "Wollaston doublet," and applied concavo-convex lenses to the purposes of the oculist.
1 That this is so, is proved by the presence of a doublet in the text of the rite of baptism, the words "But the penitent" on p. 96, as far as "over the person baptized" on p. 97, repeating in substance the words "Next the elect one" on p. 97 to "am wellpleased" on p. 98.
When S and S' lie on the same radius, taken along Ox, the Stokes' function can; be written down; and when S and S' coalesce a doublet is produced, with a doublet image at H.
35-44) closely in all respects except that of the numbers given, about which differences might easily arise in tradition, and it looks therefore as if it might be a "doublet," i.e.
32 (a doublet of v.
He was asked the meaning of the cross of St John which he wore on his doublet, and replied that it was the sign of a small benefice which he held from the pope, and would lose if he were not back by the 1st of January.
For a doublet at S, of moment m, the Stokes' function is M f cos PSx = - m p s3; and for its image at H the Stokes' function is m f cos PHx =m f 3 PH" (6) so that for the comnation _ a3 I I 2 4)-myb12 (f 3 PH PS 3) =m f 3 (pa ll 3 P53)' 3 and this vanishes over the surface of the sphere.
There is no Stokes' function when the axis of the doublet at S does not pass through 0; the image system will consist of an inclined doublet at H, making an equal angle with OS as the doublet S, and of a parallel negative line doublet, extending from H to 0, of moment varying as the distance from O.
The motion of these cylinders across the line of centres is the equivalent of a line doublet along each axis.
