J. Baprawski et al. once said that for the GUNN oscillator, turning by varying the bias voltage on the diode is not a practical method. However, we have carried out ram-wave phase-locking controlled by turning the bias voltage of the GUNN oscillator successfully. In this paper the merits of phase-locking by such a method have been discussed while the experimental results have been given.

On the basis of experimental researches on normal reversal stress due to wave inside the protective armor of sloping breakwater, this paper presents an analysis of envelope curves of maximum reversal stress with the conclusion that the instability of the protective armor of sloping breakwater mostly occurs between breaker depth and striking point, where normal reversal stress of wave attains maximum value. The influences of relevant parameters such as wave height, wave steepness, relative depth as well as slope of breakwater upon envelope curve and relationship between wave phase and that of reversal stress are also discussed. Based upon the data taken in the laboratory, statistical method is used to deduce an empirical expression of envelope curve of reversal stresses and to give the extent of most disad vantageous loading on protective armor.
