On 1 july 1975 , the us apollo spacecraft docked with the soviet soyuz spacecraft while in earth orbit . this was the first international cooperative space flight 1975年7月1日，美国阿波罗太空船利用由美国和苏联共同研发的靠站设备，与苏联的联合号一起在地球的运行轨道靠站，这是国际首次在太空飞行方面的合作。
That signal is like a gps clock that lets us track the motions of the stars , and it tells us that they are spiraling in towards each other - the orbit is shrinking very slowly 这个信号就像好比全球定位系统的时钟，我们就可以由此跟踪星体的运行，而这个信号告诉我们它们正在以螺旋形式互相靠近，也就是说它们的运行轨道正在缓慢地缩小。
Cape canaveral , florida ( reuters ) - - forty - five years in the making and 24 hours late , nasa launched a $ 700 million satellite into orbit on tuesday to test albert einstein ' s general theory of relativity 佛罗里达州，卡纳维拉尔海角- - - -历经45年蕴酿，以及推迟24小时后， nasa于周二将一颗耗资70亿美元的卫星成功发射进入运行轨道，该卫星将用来验证爱因斯坦广义相对论。
Other exhibits examine the sun - earth - moon orbital relationships and the causes of solar and lunar eclipses , the suns movement across the sky during different seasons , as well as space probe imagery of planets and their satellites 其他展品所介绍的，包括太阳地球和月球的运行轨道及其引起的日食和月食现象，太阳在不同季节的轨迹，以至太空船探测行星及其卫星之旅。
Launched into earth ' s orbit by an ariane - 5 booster rocket from kourou , french guiana , in september 2003 , smart - 1 used its ion engine to slowly raise its orbit over 14 months until the moon ' s gravity grabbed it 2003年9月， “智能1号”探测器从法国圭亚那地区的库鲁基地由ariane五号火箭发射升空，在其离子引擎的推进下， “智能1号”缓慢脱离运行轨道，在14个月后进入月球重力场。
His conceptions seemed naive to her , though she was often fired by his daring flights of comprehension , whose orbit - path was so wide among the stars that she could not follow and could only sit and thrill to the impact of unguessed power 在她眼里他的看法似乎太天真，尽管自己也常因他一套套大胆的理解而激动。他的运行轨道远在星河之间，是她无法跟随的。她只能为他那出人意外的冲撞所震撼。
According to the yi s gregorian calendar parlance , june 24th of calendar is a day when the sun goes the most positive in circulating orbit , the sun project light upon the human body to can not see own shadow at noon , so regard this day as the pleased day that celebrate 据彝族太阳历说法，日历六月二十四日是太阳在运行轨道上最正的一天，正午时太阳照射到人身上看不到自己的影子，所以把这天当作喜庆的日子。
Designed to predict the motions of hesavenly bodies , it does its job with unbelievable accuracy ? ? better than one in a hndred million for the motion of the earth around the sun ? ? and it remains in daily use to predict the orbits of moons and planets , comets and spacecraft 这个旨在预测天体运行的理论，其准确性令人难以置信? ?以地球绕太阳运转为例，其误差仅略大于一亿分之一，并且时至今日仍然每日要用它来预测卫星和行星、慧星和航天器的运行轨道。
Rating measurement has been introduced to china for no more than 20 years , so there are so many problems about its understanding and its application . for instance , the rating ( provided by cms ) was declared by the president at the spring festival performance is exactly the rating of occupation 由于收视率调查被全面纳入中国电视传播运行轨道中还是近几年的事，加上我国这一行业起步比较晚，所以我们的电视人对收视率的理解和运用方面还存在一些缺失和误区。
The seu rates caused by heavy ions and protons in space have been estimated by program calculation based on the test data , the selected environment and ion - device interaction models and the orbit , considering particles transport and shielding and the flux of particles pass shielding 然后选定空间环境模式和运行轨道，结合离子与器件相互作用模型，考虑粒子在空间的传输和屏蔽，粒子通过屏蔽材料后的通量，用计算机模拟的方式计算得出了器件在空间高能带电粒子环境中重离子和质子引起的翻转率。
