observational reference frame造句

• There is a subtle difference or distinction between these two types of simultaneity Gleizes describes that deserve closer attention : inscribed onto the canvas could be either ( 1 ) the properties of two or more physical occurrence happening at the same time from the point of view of one frame of reference ( the artist fixed in one position ), or ( 2 ) the artist could inscribe ( paint ) the properties of one event represented over a succession of time intervals, observed from several frame of reference ( or multiple points of view simultaneously expressed onto the canvas ), meaning that the observational reference frame is tied to the state of motion of an observer.
