【摘要】 用简单的物理模型解释了面心立方晶体的泊松比v₁10为负的原因。指出了其两种泊松比v₁10和v₀01的数值的理论联系。实验结果和理论符合较好。更多还原

【Abstract】 By using a simple physical model, we explain the reason why the Poisson ratio v110 in fcc crystals is negative. The theoretical relationship between the values of Poisson ratio v110 and v110 is indicated. The theory agrees with experimental results fairly well.更多还原
