12. With the reconstruction of old road, the upgrade of road scale, the accretion of traffic quantity and the manifold of heavy vehicle in my country recently, Our desire is higher and higher about the transit capacity of the old bridges. It is more impendent to confirm practice status and supporting load of these bridges on the calzada.
近年来随着我国路网改造、旧路改建和公路等级的提升，交通量的日渐增大，重型车辆的日渐增多，对原有的公路旧桥的通行能力要求愈来愈高，确定此类公路桥梁的实际使用状况和实际承载力就显得尤为迫切。
13. As the accretion disk feeds more mass into itself, the embryo star contracts, growing ever denser and more massive.
随着吸积盘获得越来越多的物质，胚胎恒星就不断收缩，密度和质量都变得越来越大。
14. In chapter three, on the basis of the new anomalous magnetic Prandtl number in accretion disks, we study the effect of dissipation on magnetic instability of Keplerian disks.
第三章在新的反常磁普朗特数的基础上，我们研究了耗散过程对开普勒盘磁不稳定性的影响。
15. It deduces from the results of calculation that the maximal contact stress have a obvious accretion at the hurt spot, the quantity is maybe 1.5 times than the normal state. But the bend stress almost the same.
从齿轮损伤后的计算结果得出：齿轮损伤处的接触应力最大值有明显的跃迁，跃迁值大约是未损伤的1.5倍，但齿轮的弯曲应力没有多大变化。
16. Aircraft can experience icing when encountering a cloud that contains supercooled water droplets. Ice accretion is a common phenomenon in flight. It is one of the main hazards to flying.
飞机积冰是飞机在积冰气象条件下飞行时，大气中的液态水在部件表面冻结并累积成冰的一种物理过程，是飞行实践中广泛存在的一种现象，也是导致飞行安全事故的主要隐患。
17. Terrain heightened can enhance blocking effect, which lead to strengthen water vapor flux divergence and vertical convection, and cloud water increases but centralizes in the middle-low level. This change intensify accretion of snow by collecting more supercooled cloud water, and rain water converts into graupel by collecting more snow, and dry growth of graupel increase at the same time. Rain water augment because of more graupel melting, and rain water continue to increase by collecting cloud water in the low level.
地形高度增加后，阻挡作用加强，使水汽通量辐合加强，垂直气流增大，中低层云水增多，导致雪撞冻过冷云水增多，促使了雨水撞冻雪转化为霰和霰干增长过程的加强，霰融化为雨水增多，低层雨水碰并云水加强，冷云过程得到增强。
18. The results show that the system can keep certain smoothness with short delay, but the control precision can decline with the accretion of time delay, long random delay will not only reduce system expeditiousness, but also the smoothness and control precision at the same time. If the random delay is long enough, it can destroy the stability of networked control systems.
研究结果表明：系统在较小的延时下仍能保持一定的稳定，随着延时的增大，系统的控制精度有所降低；而较大的随机延时不但降低系统的总体快速性，同时，使系统的稳定性和控制精度明显降低，而当随机延时大到一定程度时，系统的稳定性难以保证。
19. Sediment accretion. Changes in community structure over time are apparent from pollen analysis of sediment cores.
群落结构随时间的变化从沉积物芯样的花粉分析来看是十分明显的。
accretion的反义词
20. This paper focuses on the application of hydrodynamics and magnetohydrodynamics to solar oscillations and accretion process and outflow in star formation.
本文着重讨论了流体和磁流体力学在日震学方面和恒星形成中吸积和外流这两方面的应用。
