In spite of the granular nature, soil has traditionally been modeled as a continuum. This continuum mechanics cannot get the precise solution while soil\'s nonlinear, discontinuous, large deformation, and strain localization behavior are considered. The discrete element method is based on discontinuum theory, and is pioneered by Cundall.

土是由多相介质组成的离散颗粒集合体，尽管研究者早已在土的散粒状属性上达成共识，但关于土体力学性质的研究还经常沿用连续介质力学方法，这种基于连续体小变形假设的方法在求解实际土体非线性、非连续、大变形、应变局部化问题时往往无法得到精确解答。

In the paper, the theory and methodology of amplitude correction method using average of several points in discrete spectrum, which is suitable for analyzing the dynamic signals of rotating machinery with small varying speed, is proposed and systematically studied.

系统而完整地提出了处理变速机械弱时变响应信号的离散频谱多点平均幅值修正法的理论和方法，严格证明了该方法能精确地计算出平稳信号和频率微弱波动信号的幅值，能近似地计算出幅值和频率均微弱波动的信号的平均幅值，并应用这套理论成功地解释了频率微弱波动信号的幅值谱表现出较严重的"功率泄露"效应的原

The identified discrete time model is converted to continuous time model to convenience application.

模型检验的结果表明，辩识模型是可靠的，精确的。

The paper posits that precision and fuzziness can both be explained in terms of discreteness.

本文指出，精确与模糊，一对看似矛盾的性质，都与离散性有着紧密关系，都可以借助离散性得到解释。

Summary receiver operating characteristic analysis demonstrated better discriminatory power for MRCP than for US and CT, and better discriminatory power for US than for CT.

同时按病变部位、性质分别计算MRCP、US及CT的敏感度、特异度和似然比等指标，比较显著性检验统计学方法采用χ〓检验或精确概率法，p＜0.05为有显著性差异。
