查询词典 zenith telescope

When the Martians became depressed, everyone on the planet left the cities and went to their caves for a long time. They were stuck and couldn't come out, until one day when a Martian hap pened to glimpse the beautiful Venusians through his telescope. As he quickly shared his telescope, the sight of these beautiful beings inspired the Martians, and their Depression miraculously lifted.

当 火星人沮丧时，每个人都离开城市蛰伏到他们的洞穴里，他们陷在那里无法出来，直到有天有个火星人从他的望远镜里看见了美丽的金星人，他与其他火星人分享望远镜，镜中美丽的人鼓舞了火星人，他们的沮丧不可思议地消失了。

During 1982 to 1984, the LEST Foundation finished the possibility research, made a conceptional telescope design, carried out the experiments of helium filling and wind tunnel testing for the telescope tube and suggested a detailed financial budget with a total amount of 25 million US dollars.

自1982年到1984年，LEST基金会完成了可行性研究、方案设计，做了镜筒充氦和风洞试验，并提出了一个总额为2，500万美元的财政预算。

The telescope tube front part is the opticator, behind is a ring-like cabin, inside this cabin, in the telescope host mirror focal-plane is placing group of scientific instruments; The solar cell windsurfboard and the antenna middle partially stretch out from the tube.

镜筒的前部是光学部分，后部是一个环形舱，在这个舱里面，望远镜主镜的焦平面上安放着一组科学仪器；太阳电池帆板和天线从筒的中间部分伸出。

The standard sighting equipment includes an integral 1.5X magnification telescope sight, with the emergency backup open sights formed at the top of the telescope housing.

标准瞄准设备包括一个完整的1.5倍放大倍率望远镜看到，与在望远镜的房屋顶部形成的紧急备用开放景点。

当火星人沮丧时，每个人都离开城市蛰伏到他们的洞穴里，他们陷在那里无法出来，直到有天有个火星人从他的望远镜里看见了美丽的金星人，他与其他火星人分享望远镜，镜中美丽的人鼓舞了火星人，他们的沮丧不可思议地消失了。

The lunar optical astronomical telescope can be fixed in the cabin of the satellite outboard, so we can add a dome in the cabin to protect the telescope lens from the lunar dust.

由于望远镜可以安装在卫星最外侧的舱内，所以，可在卫星舱体上加护盖，防止月尘污染望远镜镜头。

The focusing beam radius' ratio between the telescope lens compound system and the single lens increases via length (70~400mm) increasing, and the maximum ratio is 30, meanwhile the ratio between the telescope-lens compound system and the single lens decreases via length (70-400 mm) shorting, but the maximum difference of the focusing beam radius' is 0.043μm.

结果表明，随着距离(70~400mm)的增加，两者的聚焦效果相差增大，最大为30倍；随着距离(70~400mm)的减小，两者的聚焦效果相差减小；经望远镜和薄聚焦透镜组合系统聚焦的高斯光束束腰处光斑半径随距离(70~400mm)变化的最大值为0.043μm。

The production of large, observatory telescopes continued at Jena with the first joint Zeiss telescope project being a contact signed in November of 1991 to produce a 1 meter telescope (the 13th instrument of the design made at Jena since the first one made in 1971) with control system and a 12.5 meter dome for the European Space Agency.

大型观察镜的生产还是由耶拿厂进行，1991年11月签署了合并后的第一架产品合同，生产一架安有控制系统的口径1米的大镜（是1971年首次生产后的第13架大镜），此镜配装12.5米的圆穹顶，是为欧洲航天局造的。

We are used to calling an instrument of this kind in optics a telescope, and the radioastronomical counterparts are therefore briefly named "radio telescope".

在光学上我们通常称这种类型的仪器叫望远镜，因而射电天文学上的对应物简称为&射电望远镜&。

As one of the most often used mountings, the altazimuth mounting satellite tracker has a blind area near the zenith because of the very high azimuth angular velocity, as a result, discontinuous observing data are caused. As for those fast flying satellites, this kind of blind area is very significant because it causes difficulties in precisely determining the satellites' orbits.

作为最常用的一种机架，采用地平式机架的人卫跟踪仪在观测天顶附近区域的目标时，由于方位转速过大而不能连续观测，存在一个固有的天顶盲区，特别是对飞行速度较快的近地卫星，这个盲区的影响是相当大的。

Green function defined inphase space differs from one in coordinate space by its struc-ture which exhibits nonlocatity in coordinates and oscillatorybehavior with respect to momenta.

在相空间中定义的Green函数不同于通常坐标空间的Green函数，在结构上显示出对坐标的高度非局域性，而对动量则显示出振荡行为。
