Fr.: dispositif non-linéaire
An electronic device whose output is not directly proportional to its input. For example, in a → diode the current is a nonlinear function of the voltage; its voltage-current characteristics do not obey → Ohm's law.
Fr.: dynamique non-linéaire
Same as → chaos.
Fr.: instabilité non-linéaire
The instability of a physical or mathematical system that arises from the nonlinear nature of relevant variables and their interactions within the system.
Fr.: système non-linéaire
A system in which small changes can result in large effects, and large changes in small effects.
The property, condition, or state of being → nonlinear.
Fr.: théorie quasi-linéaire
In plasma physics, the theory that considers the interactions between waves and particles are of first order only. It ignores all terms of second order in the fluctuating quantities.
In a straight line; consisting of straight lines. → curvilinear
rectilinear propagation of light
tuceš-e râst-xatt-e nur
Fr.: propagation rectiligne de la lumière
The motion of light in the first approximation, as evidenced from the formation of shadows and other every day experience. However, → diffraction
