Exempel på hur man kan använda TROCHOID i en mening

• A cycloid is a specific form of trochoid and is an example of a roulette, a curve generated by a curve rolling on another curve.
• If the point is on the circle, the trochoid is called common (also known as a cycloid); if the point is inside the circle, the trochoid is curtate; and if the point is outside the circle, the trochoid is prolate.
• These devices are sometimes called cycloidal mass spectrometers, although the path is not a cycloid (the prolate trochoid path has loops, the cycloid has cusps).
• Most authors use epitrochoid to mean a roulette of a circle rolling around the outside of another circle, hypotrochoid to mean a roulette of a circle rolling around the inside of another circle, and trochoid to mean a roulette of a circle rolling along a line.
• The corallites in small colonies are monocentric and trochoid, but become flabellomeandroiid (arranged in valleys, the neighbouring valleys having separate walls) in larger colonies.
• The thin, trochoid shell is yellowish white with rose-colored flammules and nebulosities, with more or less articulation on the spiral ridges.
• Sutherland proposed the genus Zaphriphyllum for those zaphrentids which still possess a trochoid shape and pronounced cardinal fossula and consistently have dissepiments.
