查询词典 telescopes

As a result, our telescopes and detectors are more sensitive to the effects of moonlight and we shut down for about four days on either side of the full moon each lunation.

我们的望远镜和探测者对月光非常敏感，我们会在月圆的前后大约四天关闭望远镜。

You can still see the gas or nebulosity in big telescopes and the right filters.

用大望远镜和适度的滤色镜，你也可以看到那些气体或星云状物。

Based on the third-order aberration theory of two-mirror reflecting system, the influence of the geometrical aberrations on the performance of normal incidence telescopes was analyzed.

基于三级象差理论，分析了几何象差对正入射望远镜性能的影响，总结了弥散斑角宽度θ随着系统f数和半视场角uP的变化趋势。

For example, reflecting telescopes are still built with paraboloidal primary mirrors, which have interchangeable flat diagonal mirrors and hyperboloidal secondary mirrors, with a focuser installed both at the Newtonian focus and the Cassegrain focus.

例如，同样是抛物面反射望远镜，然而安装了可切换的45度反射镜与双曲面副镜（注：分别对应于典型的牛顿与卡塞系统），且在牛顿和卡塞焦点都装有成像设备。

Two Neapolitan Chinese priests and a hot-air balloon pilot. Packed into three substantial ships, they brought with them the most impressive fruits of recent Western scientific progress ─ telescopes, clocks, barometers

最高级的西方科研成果：望远镜，钟表，热气球，等等，这些珍贵的礼品是送给乾隆的，目的是想让乾隆相信西方的发达技术，英国的这些技术是拥有三亿一千三百万人口的中国所需要的，中英贸易夥伴关系是有利于清朝的。

We also believe there is a chance that the impact plume may be visible in 10 to 12 inch amateur telescopes.

我们还认为有机会羽的影响可能会在10至12英寸可见业余望远镜。

They had remained curiously isolated from the changes elsewhere in India. Few European innovations - watches, clocks, telescopes - had reached the Rajput desert.

他们仍然好奇地孤立于其他地方印度的变化，一些欧洲创新手表、钟表、望远镜已达到拉杰普特沙漠。

The reflecting telescope, pioneered by Isaac Newton in the 17th century, later became the instrument of choice because of its use of mirrors, which could be constructed successfully at much great sizes than the glass lenses used in refracting telescopes.

反射望远镜是艾萨克·牛顿于17世纪首先倡导的，后来由于望远镜上反射镜的应用面成为了一种首选的设备，比起折射望远镜里使用的玻璃透镜来，它能够成功建造出尺寸大得多的望远镜。

Reflector telescope relative a larger diameter can be done, the main focus of the relative telescope diameter is about 15-125, even greater, Wang DC, inter Newton Telescope, the tube is longer than the system is much shorter focal length, coupled with the main mirror is only one apparent need for processing, which greatly reduces cost and manufacturing difficulties, there is currently greater than 134 meters diameter optical telescopes are all reflecting telescope.

反射望远镜的相对口径可以做得较大，主焦点式反射望远镜的相对口径约为15—125，甚至更大，而且除牛顿望DC远镜外，镜筒的长度比系统的焦距要短得多，加上主镜只有一个表面需要加工，这就大大降低了造价和制造的困难，因此目前口径大于134米的光学望远镜全部是反射望远镜。

What's more, since these detectors can look down through the Earth to see the universe, using the whole planet as a shield to absorb the riffraff of particles from the atmosphere, telescopes in different hemispheres can better observe neutrinos coming from all over the sky.

更为重要的是，这些探测器能够透过地球观测宇宙，它们将整个地球作为屏障，吸收来自大气层的粒子；将望远镜至于不同半球能够更好地观测来自整个天空的中微子。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
