Oscillator is a type of energy conversion device -- the DC electric energy into a certain frequency of AC electric energy, its composition of the circuit called the oscillation circuit. Oscillators can be divided into two main types: harmonic oscillators and relaxation oscillators. Oscillator is mainly used in medical, petrochemical, health and epidemic prevention, environmental monitoring and other scientific research departments for biological, biochemical, cell, bacterial species and other liquid, solid compound oscillation culture. The oscillator consists of a process and function from non-oscillation to oscillation.
