The phrase "a axis that" is not correct in written English.
It should be "an axis that" because "axis" begins with a vowel sound.
Example: "We need to define an axis that represents the relationship between the two variables."
Alternatives: "a line that" or "a reference that".
Cervical kinematics were computed using the helical axis method, which describes the movement of a segment as a rotation around and a translation along an axis that is allowed to move in space [ 22].
CXL makes use of a rotation around an axis that is not perpendicular to the radiation source/detector axis but that is tilted relative to it (Figure 1E).
The predominant and perhaps primitive growth form in a wide range of monocots is sympodial growth, a creeping habit consisting of an axis that appears to be continuous but is actually made up of a succession of elements.
In the L to T transition, R1 and R2 undergo a rocking motion around an axis that is tilted relative to the membrane plane.
B Company would then assault in a south-east direction on an axis that would take them across the front of A Company, which would require their fire to cut-out as they did so.
The Great Houses of Pueblo Bonito and Chetro Ketl were found by the "Solstice Project" and the U.S. National Geodetic Survey to be sited along a precisely east-west line, an axis that captures the passage of the equinox sun.
Earth rotates once every 24 hours around an axis that is tilted at an angle of 23°30′ with respect to the plane of its orbit around the Sun.
The opponent's faces were derived from an online database that morphed neutral faces along an axis that optimally predicts people's subjective ratings of trustworthiness [27].
The dispersion pattern is dominated by rotation about an axis that plunges shallowly to the SE which is a similar trend to most of the >1° boundaries (Fig. 3a,b).
Angular momentum, property characterizing the rotary inertia of an object or system of objects in motion about an axis that may or may not pass through the object or system.
