双筒望远镜能不能翻译成double-tube telescope

双筒望远镜能不能翻译成double-tube telescope,第1张

一般不这么说。

双筒望远镜是两个眼睛一起看的,所以英语里用双目()来定义,完整的表述是:binocular telescope,日常行文中,在前后文能呼应时,也可以单独用binocular表示双筒望远镜。

另外有个复合词 field-glasses,意思是双眼一起看的时候是有立体感的一个大视野,所以也用来表示双筒望远镜。

给你详细一点,你自己摘抄吧,这样可能合适一点:

A telescope is an instrument designed for the observation of remote objects by the collection of electromagnetic radiation The first known practically functioning telescopes were invented in the Netherlands at the beginning of the 17th century "Telescopes" can refer to a whole range of instruments operating in most regions of the electromagnetic spectrum

The word "telescope" (from the Greek tele = 'far' and skopein = 'to look or see'; teleskopos = 'far-seeing') was coined in 1611 by the Greek mathematician Giovanni Demisiani for one of Galileo Galilei's instruments presented at a banquet at the Accademia dei Lincei[1][2][3] In the Starry Messenger Galileo had used the term "perspicillum"

The earliest evidence of working telescopes were the refracting telescopes that appeared in the Netherlands in 1608 Their development is credited to three individuals: Hans Lippershey and Zacharias Janssen, who were spectacle makers in Middelburg, and Jacob Metius of Alkmaar[4] Galileo greatly improved upon these designs the following year

The idea that a mirror could be used as an objective instead of a lens was being investigated soon after the invention of the refracting telescope[5] The potential advantages of using parabolic mirrors, primarily reduction of spherical aberration with no chromatic aberration, led to many proposed designs and several attempts to build reflecting telescopes[6] In 1668, Isaac Newton built the first practical reflecting telescope that bears his name, the Newtonian reflector

The invention of the achromatic lens in 1733 partially corrected color aberrations present in the simple lens and enabled the construction of shorter, more functional refracting telescopes Reflecting telescopes, though not limited by the color problems seen in refractors, were hampered by the use of fast tarnishing speculum metal mirrors employed during the 18th and early 19th century—a problem alleviated by the introduction of silver coated glass mirrors in 1857,[7] and aluminized mirrors in 1932[8] The maximum physical size limit for refracting telescopes is about 1 meter (40 inches), dictating that the vast majority of large optical researching telescopes built since the turn of the 20th century have been reflectors The largest reflecting telescopes currently have objectives larger then 10 m (33 feet)

The 20th century also saw the development of telescopes that worked in a wide range of wavelengths from radio to gamma-rays The first purpose built radio telescope went into operation in 1937 Since then, a tremendous variety of complex astronomical instruments have been developedThe name "telescope" covers a wide range of instruments and is difficult to define They all have the attribute of collecting electromagnetic radiation so it can be studied or analyzed in some manner The most common type is the optical telescope; other types also exist and are listed below

Optical telescopes

50 cm refracting telescope at Nice Observatory

Main article: Optical telescope

An optical telescope gathers and focuses light mainly from the visible part of the electromagnetic spectrum (although some work in the infrared and ultraviolet) Optical telescopes increase the apparent angular size of distant objects as well as their apparent brightness In order for the image to be observed, photographed, studied, and sent to a computer, telescopes work by employing one or more curved optical elements—usually made from glass—lenses, or mirrors to gather light and other electromagnetic radiation to bring that light or radiation to a focal point Optical telescopes are used for astronomy and in many non-astronomical instruments, including: theodolites (including transits), spotting scopes, monoculars, binoculars, camera lenses, and spyglasses There are three main types:

The refracting telescope which uses lenses to form an image

The reflecting telescope which uses an arrangement of mirrors to form an image

The catadioptric telescope which uses mirrors combined with lenses to form an image

Other optical telescopes:

Infrared telescopes

Submillimetre telescopes

Ultraviolet telescopes

Fresnel Imager

Radio telescopes

Main article: Radio telescope

The Very Large Array at Socorro, New Mexico, United States

Radio telescopes are directional radio antennas used for radio astronomy The dishes are sometimes constructed of a conductive wire mesh whose openings are smaller than the wavelength being observed Multi-element Radio telescopes are constructed from pairs or larger groups of these dishes to synthesize large 'virtual' apertures that are similar in size to the separation between the telescopes; this process is known as aperture synthesis As of 2005, the current record array size is many times the width of the Earth—utilizing space-based Very Long Baseline Interferometry (VLBI) telescopes such as the Japanese HALCA (Highly Advanced Laboratory for Communications and Astronomy) VSOP (VLBI Space Observatory Program) satellite Aperture synthesis is now also being applied to optical telescopes using optical interferometers (arrays of optical telescopes) and aperture masking interferometry at single reflecting telescopes Radio telescopes are also used to collect microwave radiation, which is used to collect radiation when any visible light is obstructed or faint, such as from quasars Some radio telescopes are used by programs such as SETI and the Arecibo Observatory to search for exterrestrial life

High energy particle telescopes

The Einstein Observatory, an X-ray telescope originally named the HEAO B (High Energy Astrophysical Observatory B)

High-energy astronomy requires specialized telescopes to make observations since most of these particles go through most metals and glasses

X-ray telescopes use Wolter telescopes composed of ring-shaped 'glancing' mirrors made of heavy metals that are able to reflect the rays just a few degrees The mirrors are usually a section of a rotated parabola and a hyperbola, or ellipse In 1952, Hans Wolter outlined 3 ways a telescope could be built using only this kind of mirror[9][10]

Gamma-ray telescopes refrain from focusing completely and use coded aperture masks: the patterns of the shadow the mask creates can be reconstructed to form an image

X-ray and Gamma-ray telescopes are usually on Earth-orbiting satellites or high-flying balloons since the Earth's atmosphere is opaque to this part of the electromagnetic spectrum

In other types of high energy particle telescopes there is no image-forming optical system Cosmic-ray telescopes usually consist of an array of different detector types spread out over a large area A Neutrino telescope consists of a large mass of water or ice, surrounded by an array of sensitive light detectors known as photomultiplier tubes

哈勃空间望远镜。

哈勃空间望远镜(英语:Hubble Space Telescope,缩写:HST)是以美国天文学家爱德温·哈勃为名,于1990年4月24日成功发射,位于地球的大气层之上的光学望远镜。

2019年5月,哈勃太空望远镜科学家公布了最新的宇宙照片——“哈勃遗产场”(HLF),这是迄今最完整最全面的宇宙图谱,由哈勃在16年间拍摄的7500张星空照片拼接而成,包含约265000个星系,其中有些已至少133亿岁“高龄”,对其进行研究有助于科学家深入了解更早的宇宙历史。
