A fatigue degree measuring device (1) includes: biological signal peak value detection means (23) for detecting a peak value of each cycle of the raw waveform of biological signal data; power value calculation means (24) for calculating a difference between the peak value of the upper limit side and a peak value of the …
ادامه مطلبAs the rotation speed of the high-speed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is 0.6-1.2 [49, 50]. The parameter setting of the ball mill is shown in Table 1.
