A star precipitated with great apparent velocity across the firmament from vega in the lyre above the zenith beyond the stargroup of the tress of berenice towards the zodiacal sign of leo 一颗星星从天顶上天琴座“织女一”越过后发星座188的星群，明显地以高速度朝着黄道十二宫的狮子宫189直冲过去。
We impute it , therefore , solely to the disease in his own eye and heart , that the minister , looking upward to the zenith , beheld there the appearance of an immense letter - the letter a - marked out in lines 因此，当牧师抬眼眺望天顶，看到出现了用暗红色的光线勾出的巨大字母“ a ”时，我们只能归结为他由于心病而眼睛出了毛病。
By measuring the brdf of a kind of typical material - granite , sample ' s hemisphere reflectivity has been acquired and the law of its dependence on the zenith - angle and azimuth - angle variation has been studied 摘要对以大理石为代表的材料进行了双向反射分布函数测量实验，得出了样品的半球反射率，并研究了其随入射、反射天顶角等参数变化的规律。
The variation of ztd is mainly caused by the zenith wet delay ( zwd ) . zenith hydrostatic delay ( zhd ) and zwd from different gps sites exhibit individual features that zhd has a obvious periodic change and zwd is related to weather 总延迟的变化主要是由湿延迟的变化而引起，其中静力延迟变化呈现了明显的周期性，而湿延迟的变化与天气过程相关联。
Ocean tide has an effect on gps stations and there is a strong correlation between the vertical displacement and the zenith delay at a gps station , so the effect of ocean tide on the precise determination of gps stations " coordinates , baseline vectors , and zenith delay should not be neglectable 由于海潮对测站位移的影响以及测站垂直位移与天顶延迟存在很强的相关性，所以海潮对精密测定测站坐标、基线和天顶延迟的影响不可忽略。
This means the effects can be reduced by long - term continuous observation . but for the short - time observation , for example , the determination of zenith delay , the effects ca n ' t be reduced obviously , because the interval between the zenith delay parameters is often short 这说明长时间的连续观测可以削弱海潮的影响，但对于短期的观测，比如在估计天顶延迟量时，由于估算天顶延迟参数的时间间隔通常较短，海潮的影响还是不能很好地抵消。
This conflict reached the zenith during the later half period of the 19th century and the initial stages of the 20th century . there were two patterns with which humanistic education combined with science education , one was humanistic education sciencized and the other was science education humanism 前者在融合人文教育与科学教育做法上倾向于以科学为准则、核心或取向的方式来融合两种教育;而后者则主张以人文为目的、主轴或取向的方式来融合两种教育。
And at the zenith of his fame , how he would suddenly appear at the old village and stalk into church , brown and weather - beaten , in his black velvet doublet and trunks , his great jack - boots , his crimson sash , his belt bristling with horse - pistols , his crime - rusted cutlass at his side , his slouch hat with waving plumes , his black flag unfurled , with the skull and crossbones on it , and hear with swelling ecstasy the whisperings , " it s tom sawyer the pirate 只见他上身穿件黑色绒布紧身衣，下身是条宽大短裤，脚蹬肥大长统靴，还背着大红肩带，腰带上挂着马枪，身边还别了把用损了的短剑。那顶垂边的帽子上飘着翎毛，黑旗迎风招展，上面交叉着骷髅头和白骨。听到别人悄声低语： “这就是海盗汤姆索亚西班牙海面上的黑衣侠盗！ ”
A pure software solution is given in order to gather more tracking data . the reason of the zenith - blind - zone forming is analyzed detailedly . the conclusion is that the extent of the zenith blind zone was restricted by three parameters : maximum azimuth angular velocity of tracking mount , flight level and airspeed of the target 本文依据不改变系统硬件结构的研究思路，提出一个基于目标轨迹预测技术的解决过天顶跟踪的方案构想，给出具体实施步骤，预计可使系统单站单圈次跟踪采集到的有效数据总量提高约一倍。
But there are still many things need to do . to improve the situation , under the direction of my teacher , i began to observe the zenith luminance of clear sky and overcast sky . and after analyzing the observed data , i drew the zenith luminance in beijing 虽然如此，通过对北京地区晴天和阴天天顶亮度的观测，仍可以得到北京地区晴天和阴天天顶亮度随太阳高度角变化的规律，从而得到天顶亮度值，将其代入cffi标准晴天和阴天天空亮度公式后得到北京地区的晴天和阴天天空亮度绝对值。
