Discussion on the Mechanism of the Modification PPF Influencing the Compressive Strength of the Concrete───改性聚丙烯纤维影响混凝土抗压强度的机理初探
The blanketed zone of support jamming is computed by the pattern propagation factor (PPF) with different reflection coefficient and carrier frequency.
PPF can suppress switch's drop-out peak-voltage and magnetic biasing by adding a clamping capacitor on primary side of the traditional push-pull converter's transformer.
The PPF capacitor parameters are realized by the multi-objective optimal program in MATLAB.
