First of all, the history of phase locked technology and the actuality of researches on it are introduced. Then, beginning with the fundamental principles of a phase-locked system, we build the mathematical model based on the architecture of the traditional analog PLL, and afterwards investigate some of its characters such as tracking, acquisition, noising, and stability. The system parameters are developed at the same time, and some universal conclusions on the theoretical analysis of PLL are reached.

A hotwire anemometer was used to measure the jet velocity at the exit of the precessing jet nozzle and the power spectrum density was obtained afterwards in order to analyze the precessing feature of the jet. It is shown that an obvious precession motion is generated in a nozzle even with a large expansion ratio E=10 and a small length-to-diameter ratio LD=2. The precessing frequency is mainly dependent on the nozzle diameter and the intake flow rate, increasing with the enhancement of the flow rate and with the reduction of nozzle diameter.
