The phrase "alternation system" is correct and usable in written English.
It can be used in contexts discussing systems that involve alternating processes, patterns, or states, such as in linguistics, biology, or engineering.
Example: "The alternation system in this model allows for efficient resource management during peak times."
Alternatives: "alternating system" or "switching system".
In Europe, two different systems came into prominence over the following decade: in Germany Walter Bruch developed the PAL (phase alternation line) system, and in France Henri de France developed SECAM (système électronique couleur avec mémoire).
Because the conditioning factors were involved with morphological process (affixation and consonant alternation), tonal systems could also acquire certain grammatical or structural functions.
On the other hand, a rotation of graphene layers with respect to each other, particularly in the case of low twist angles (below 10°), may result in an alternation of the system's low-energy electronic structure, such as a reduction of the Fermi velocity and associated localization of charge carriers [36, 37], which may in turn alter the electronic and magnetic properties of the vacancy.
It might be expected that a response which is composed of the alternation of two systems with different properties would extinguish the periodicities of the constituent sub-models.
These were at first patricians; but those of the next year were plebeians and so on year by year alternately until, in the 2nd century bc, the system of alternation between classes ceased.

By no means everyone believes that the NDP's effort to create a semblance of democracy will eventually lead to the real thing: a genuine multi-party system with alternation of power.
The torus grows as k increases, and parts of the torus shadow the attracting and repelling branches of periodic orbits of the fast system in alternation.
The torus canard orbits spend long times near branches of attracting and repelling periodic orbits of the fast system in alternation, switching over from the former to the latter exactly near the saddle-node of periodic orbits.
