Compared with the existing products containing L-lysine, the products can remarkably improve hygroscopicity resistance and are suitable for being stored for a long time. The preparation method is good in flexibility and controllable in cost.

The invention discloses a method for ultrasonic-assisted electrolytic plasma polishing of a titanium alloy. The method includes the steps that firstly, a mixed electrolyte containing sodium aluminate,sodium hexametaphosphate and potassium hydroxide is blended to serve as a polishing solution; a titanium alloy test piece is immersed into a stainless steel tank containing the polishing solution, the titanium alloy test piece is connected with an anode, and the stainless steel tank is connected with a cathode; then a double-pulse power supply with the positive polarity voltage of 350 V-450 V, the negative polarity voltage of 30 V, the pulse frequency of 350 Hz-450 Hz and the duty ratio of 35%-45% is applied between the cathode and the anode; the current waveform in the polishing process is detected, and an ultrasonic cavitation effect with the oscillation frequency of 30 kHz-50 kHz is applied to the polishing solution only through an ultrasonic device at the bottom of a polishing tank inthe inter-pulse stage of the waveform; and a circulating water cooling system is adopted for cooling the polishing tank, so that the temperature of the polishing solution is kept at about 60 DEG C, and the titanium alloy test piece is polished for at least 10 min. According to the method, the ultrasonic-assisted electrolytic plasma polishing technology is adopted, and effective polishing of a complex wall face and a cavity of the titanium alloy is achieved through the effects of electrochemical oxidation passivation, discharge plasma etching activation, ultrasonic enhanced activation and thelike.

The invention innovatively discloses a structure earthquake oscillation monitoring system and method based on a smart phone or tablet computer equipment.
