Two properties for the incenter and the medians of a triangle is extended to an n-dimensional simplex, and two properties for the incenter and the middle planes of an n-dimensional simplex is obtained.

This paper, by means of algebraic methods, discusses the positional relations and metric relations of barycenter, excenter, incenter, orthocenter in a simplex cone whose lateral edge lengths are equal.

Using theory of distance geometry,we discuss the necessary and sufficient conditions for the section of a simplex cone crossing the incenter or center of gravity.

The Mark on the Wall,written by Virginia Woolf,is regarded as one of her best short stories,in which she breaks the traditional writing methods and skillfully employs some narrative skills as variable perspec-tive,internal monologue,time and space arrangements which belong to techniques of stream of consciousness.

Through "internal monologue" and "poeticized novel", she displayed the internal activities of the character and depicted the image of.

Toni Morrison accomplished her creativity of its complex theme and structure by multidimensional nonlinear arrangements, bounding space structures, indirect monologues and narration of multiple points of view.

Eliot made use of paradox as the main structure,adding with symbolism, interior monologue and literary allusion, to reflect his poetic theory,e·g·"impersonal theory "and "objective correlative" of his early age.
