中文拼音 [juérètīdù]
絕熱梯度
英文
adiabatic gradient-
The effect of the strain gradient on the onset of adiabatic shear instability in gradient - dependent particle reinforced metal matrix composites is investigated by using of linear perturbation analysis in this paper. the analytical results demonstrate that high strain gradient produced by the reinforcing particle will provide a strong a deriving force for the onset of adiabatic shear instability in mmcp
結果表明：增強顆粒的加入，改變了基體材料的微結構，並在基體中誘導了高的應變梯度，而這種高的應變梯度為mmcp的失穩提供了強大的驅動力，使其更易發生絕熱剪切變形局部化失穩。The saffman force does not affect the axial velocity of the flow, while it change the concentration of the particle. the gas - particle two - phase flows in the present of temperature were also numerical simulation
