antedate
anticipation
Examples
- Due to various corrosive effects , reinforced concrete structures in corrosive environments had shown serious deterioration , which usually caused by concrete deterioration , rebar corrosion , degradation of bond strength between rebar and concrete
腐蚀环境下服役的钢筋混凝土结构由于长期受到腐蚀作用，造成混凝土性能劣化、钢筋锈蚀、钢筋与混凝土之间粘结退化，导致钢筋混凝土结构耐久性降低而提前发生破坏。 - The numerical results from the phase portraits , the period - doubling bifurcation and the poincare sections show that external stochastic excitation always masks the regular motions of a deterministic system and plays a dissipative role to the motions of the system , which causes the chaotic motions of the system to arise easily , though the period - doubling bifurcation is delayed
系统的相图、倍周期分岔图以及庞加莱映射图等方面的数值结果表明，外加随机激励的作用往往掩盖原确定性系统内在的规则运动，对原确定性系统的运动具有较典型的分散作用，可延缓系统的倍周期分岔，也可使得系统内在随机行为提前发生，即可使得系统更容易出现混沌运动。 - It has been shown that : with the increase of the kerr medium intensity parameter u , the rabi oscillation extent of the mean photon number decrease and the rabi oscillation frequency becomes rapid , the antibunching effect becomes strengthened ; with the increase of n , the interaction between the field and atoms gradually becomes weak , however , the interaction between the field and the kerr medium gradually becomes strengthened and happen in advance ; with the increase of the coupling constants of two atoms , the rabi oscillation extent of the mean photon number decrease and the rabi oscillation frequency becomes rapid too , the antibunching effect becomes weak
结果表明：随着值的增加，光子统计演化曲线的rabi振荡的幅度减小，振荡频率变快，系统的反聚束效应增强；随着初始场强( ? )的增大，场与原子的相互作用逐渐减弱，而与介质的相互作用逐渐加强并提前发生。随着原子间耦合系数g的增大，光子统计演化曲线的rabi振荡的幅度减小且振荡周期缩短，同时，系统的反聚束效应减弱。 - Combining gray theory and catastrophe theory , the gray energy catastrophe model is brought out according to the critical value of energy . the real example shows that the critical value is unique . the analytical process of rock mass fail shows that the process of fail of the rock mass is the process that dissipation structure is formed , and that self - organization of surrounding rock is built during the process
在临界状态时，只要系统稍有扰动，则系统就会失稳；强扰动可以使失稳提前发生；将灰色理论和突变理论相结合，以能量突变为材料的破坏特征，提出隧道岩体开挖的灰色能量突变模型，通过实例分析表明，该失稳判据具有唯一性；对岩体失稳的过程分析表明，岩体的失稳过程实际上是耗散结构的形成过程、是岩体的自组织过程，围岩系统在演化过程中出现分叉和混沌现象。
