A novel vital sign detection algorithm based on trajectory capture and peak capture is proposed to solve the problem that the heartbeat signal of slightly moving subjects is easily interfered by breathing harmonics and other clutter. First, the received signal is processed by the average cancellation method to suppress the stationary clutter. Then, we use the trajectory capture algorithm to catch the moving trajectory of the subject, use the trajectory to correct each received pulse, and use the distance gate selection algorithm to extract the body surface vibration signal. After that, the body surface vibration signal was subjected to low-pass filtering in the frequency domain and autocorrelation processing to improve the signal-to-noise ratio of the signal. Finally, the frequency-domain peak capture algorithm of N iterations was used to extract the vital signs of the signal. Simulation results show that the algorithm can accurately extract the vital signs of slightly moving subjects, and has higher measurement accuracy and better stability than the traditional algorithm.

QAl10-4-4 aluminum bronze alloy was subjected to solid solution and aging treatment at different temperatures, and the changes in microstructure and properties were studied through metallography, hardness, impact energy and wear. The results show that with the increase of solution temperature, a and K phases gradually shrink until they are dissolved into the alloy matrix, the alloy grains grow up and the hardness increases. The P' phase decomposes into α+γ2 eutectoid structure, the hardness gradually decreases, and the impact energy shows an increasing trend with the aging temperature increasing. Dynamic recrystallization occurs after aging at 700°C. The change of the wear weightlessness is more complicated, and there is no obvious change characteristic. When aging at 500°C, the minimum weight loss of wear is 0.5291g.

This paper introduces the preparation method and performance study of chemical vapor deposition (CVD) tungsten composite coating on TC4 titanium alloy surface. The magnetron sputtering method is used to introduce an intermediate transition layer to avoid corrosion of the titanium substrate by the formation of oxides on the surface of the titanium alloy and HF formed by CVD. After the performance test, the binding force of the composite coating and the titanium substrate was improved, and the wear resistance and corrosion resistance of the titanium alloy surface were further improved.

Diamond coating was deposited on polycrystalline diamond (PCD) substrate with CH4/H2/CO2 using microwave plasma CVD system. PCD substrates A, B and C which differ in the ratio of metallic binders were predetermined preparation methodology. In order to get better adhesive strength, diamond coating grown on the different PCD substrates was studied. The overall performance of the diamond coating was measured by scanning electron microscope (SEM), Raman spectrum and the Rockwell indentation tests. Results clearly indicate that substrate C is the best substrate among three PCD substrates. In addition, with the decrease of Co and W content in the matrix, the increase of Cu content is helpful to improve the adhesion of diamond bit coating, which provides guidance for the industrialization of diamond bit coating.

A shaft of the air compressor broke during use. By means of scanning electron microscope analysis, metallographic analysis and energy spectrum analysis, the fracture reason of the shaft was analyzed systematically. The results show that the broken shaft material is not subject to solution treatment or the solution treatment is unqualified. The fracture of the shaft is caused by a large force in a short time.
