The two troughs are held in a fixed orientation relative to each other by being both fixed to a frame.
Unlike the coping saw, the blade has a fixed orientation in relation to the frame.
It is a numerical definition of a fixed orientation in space and is usually (but not always) defined with respect to the stars.
It would be nice to look at just a few atoms or molecules with a fixed orientation.
This means that, with appropriately arranged samples, one could look at the electron distributions of single molecules at a fixed orientation.
Polarization describes the spatial relationship between the electromagnetic fields and some fixed orientation, defined by the experiment (e.g., the laboratory table).
As Agena was designed to hold a fixed orientation in space while orbiting Earth, a passive thermal control system was devised.
This deformation has a fixed spatial orientation relative to the influencing body.
The system has at least a fixed orientation in three dimensional Euclidean space.
In what follows, attention is restricted to simple rotation about an axis of fixed orientation.
