The results show: the strongest bond is the Al-Al bond in the segregated cell without containing vacancy, where the Al atomic covalence radius is greater than that of Li atom in the cell; while the strongest bond is the Al-Li bond in the segregated cell containing vacancy, and the Al atomic covalence radius in the cell is less than that of Li atom. Since the difference of electronagativity between the Al and Li atoms is obvious, it is inclined to formed the Al-Li segregated cell of short range order structure in the condition of vacancy present. The short range order structure containing vacancy is probably the embryo or precursor structure of the metastable phase δ'(Al3Li). Because the strongest covalent bond in the Al-Li-vacancy segregated cell in alloy formed in quenching is the main strength reason for supersaturated solid solution of alloy. The bond net of succeeding precipitation of δ'(Al3Li) has the picture of anisotropic Al-Al bonding and the bond intensity enhanced. Since the δ'(Al3Li) is coherence with matrix, the bond net strength is enhanced by the precipitation of δ'(Al3Li) and so strengthen the alloy.

He had lost the sense of what the Chorus was in the hands of the great masters, say in the Bacchae or the Eumenides. He mistakes, again, the use of that epiphany of a God which is frequent at the end of the single plays of Euripides, and which seems to have been equally so at the end of the trilogies of Aeschylus. Having lost the living tradition, he sees neither the ritual origin nor the dramatic value of these divine epiphanies. He thinks of the convenient gods and abstractions who sometimes spoke the prologues of the New Comedy, and imagines that the God appears in order to unravel the plot. As a matter of fact, in one play which he often quotes, the _Iphigenia Taurica_, the plot is actually distorted at the very end in order to give an opportunity for the epiphany.
