顶向

Astronomy A point on the celestial sphere directly below the observer, diametrically opposite the zenith.

天底：天球上，在观测者垂直向下的一点，与天顶完全相对

In our views, the region of the CMI, near the ionosphere of Saturn (1 Saturn radius above the polar area), is regarded as the same area as the Saturn's Kilometric Radiation Source.In this paper, we deduce that the KHI will appear before 11 LT (Saturn's Local Time), the Alfven wave will take 383 min to reach Saturn, the sunward magnetic line will bend almost 80°. Finally, we get the distribution of SKR source. It locates from 7～9 LT at a relatively lower latitude to 18 LT at the eveningside.

本文求出了磁层顶附近开尔文-亥姆霍兹不稳定性发生在土星本地时（Saturn's Local Time）11 LT以前，得出了阿尔芬波沿磁力线传播到土星需要约383 min，求解出向阳面磁力线弯曲了约80°，最后得出土星千米波辐射源分布从黎明段的7～9 LT延伸到傍晚段的18 LT，并且黎明段分布的纬度比傍晚段低。

The in_ cavity residual stress in first principal direction result shows the forces left in the part after ejection in the orientation direction.

第一方向残余应力？品顶出时在配向方向上的残余在产品中的力。

The interactions among large air voids, the dynamic hydraulic pressure, the non-uniformly distributed load, the overload, the environment condition and the material lead to the deficiency of the adhesion between asphalt and aggregate. The immigration of the asphalt leads to the new bleeding and inside raveling. The pumping and settlement occurred once the water penetrates the whole asphalt layer.

大空隙率、动水压力、荷载的非均布、超载以及气候条件与路面材料的相互作用造成了沥青与集料粘附性的相对不足，面层内部沥青膜剥落后向上部迁移，这是新泛油、内部松散的产生机理；更为严重的情况下，外界水直接贯穿沥青面层对基层顶面的冲刷将诱发泛浆和沉陷。

Finally, the second option was identified as the recommendatory handling technology of heavy cargo wharf in Xiangjiaba, which could meet the needs of the safe and efficient transit.

本文系统的总结了目前重大件运输中常见的装卸工艺，针对向家坝重大件码头拟采用的3000t级滚装船采用滚装卸船工艺和1000t驳船采用顶推卸船工艺或吊装卸船工艺方案的工艺流程进行了详细的阐述。

Astronomy the angular distance of a celestial point measured westward along the celestial equator from the zenith crossing; the right ascension for an observer at a particular location and time of day.

从天顶交叉口向西顺着天赤道测量的一个角距离；对在一个特定的地点和特定的时间观测者来说是赤经。机会难得！足额稳定绿色激光笔团购！

When Sinlaku hit Taiwan during September 12-15, 2008, the extremely torrential rain made Hou-Fong Bridge, located in downstream of Shi-Gang Dam, broken at around 6:50 p.m. on September 14, 2008. In this study, the case was applied to investigate the factors which resulted in the typhoon flood scour disaster and the disaster prevention mechanism, including the general scour of upstream and downstream river banks, the riverhead erosion and constriction scour, the free fall of broad-crested weir effect caused by water-pipe protection engineering, the disaster prevention and response of the bridge care and management unit, and the examination, timing and procedure of bridge block.

中文摘要本研究系以97年9月12日至15日强烈台风辛乐克侵袭台湾期间，所降下的超大豪雨造成位在大甲溪石冈坝下游后丰大桥於9月14日下午6点50分左右发生断桥事件为例，探讨台洪冲刷灾害成因与防灾应变机制，包含上下游河道之一般冲刷、河道向源侵蚀与束缩冲刷及位於桥梁上游约20公尺处之自来水干管保护工所产生宽顶堰跌水效应等影响，并检讨桥梁养护管理单位於断桥发生前防灾应变处置方式及台洪期间之巡查检测、封桥时机与封桥作业流程等等相关因应作为。

It shows that the design of tailrace tunnel with sloping ceiling is suitable and provides a hard foundation for the project design.

第五章：综合介绍了其他几家科研单位的研究结果，总结向家坝电站变顶高尾水洞的成果。

According to the characteristic of Xiangjiaba Underground Hydropower Station at the right bank of Jinsha River, one alternative option that the tailrace tunnel with sloping ceiling is adopted has been studied comprehensively, by method of model test and numerical calculation.
