查询词典 star catalogue

Most astrometry software packages use the Guide Star Catalogue, so a CD-ROM drive is also required.

很多天文软件包都使用引导星目录库，所以配置一个光驱也视必要的。

Because it is not practical to use numerical ephemerides with a large volume of data to describe the kinematics of component stars in a star catalogue, a kinematics model, as simple and practical as possible, is needed for the hierarchical triple star systems.

因为在实用星表参考架中不宜采用数据量较大的数值历表来描述子星的运动，所以有必要针对等级三星系统建立尽可能简单实用的运动学模型。

The software will use the brightest stars in the image and in the star catalogue for the matching routine.

软件将使用图片和星表中最亮的恒星进行匹配。

When using a star catalogue that is complete down to a certain limiting magnitude (i.e., the USNO-A2.0 or the UCAC ), a small number of stars (10 to 30) is usually sufficient.

当使用的星表是那种完全限定在某极限星等之下的数据的（比如：USNO-A2.0或UCAC星表），一个比较小的匹配星数目就一般足够了。

In this section, you can define various settings used by the software when it tries to match the stars detected in the image with the reference star data read from the star catalogue.

在这一部分，你可以定义多种设置来配合参考星的匹配。

Search Radius: The search radius, in pixels, used by the software when it tries to find the stars listed in the reference star catalogue in the image.

搜索半径：以像素为单位的搜索半径。

Until quite recently, the only useable catalogue for CCD observers was the Hubble Space Telescope's Guide Star Catalogue, that contains about 18 million objects.

直到目前，对于CCD观测者唯一合适可用的星表是GSC（哈勃空间望远镜的引导星参考星表），它包含1.8亿个目标。

If a star is located within the search radius from the predicted position, the software assumes that this star is identical with the star listed in the catalogue.

是软件进行参考星自动匹配的搜索半径。

Stellarium has many data files containing such things as star catalogue data, nebula images, button icons, font files and configuration files.

Stellarium 含有很多数据文件用以存放星表数据、星云图片、按钮图标、字体和配置等等。

The first Astronomer Royal, John Flamsteed, compiled the most accurate star catalogue of his day as part of this attempt (though the solution was eventually provided by John Harrison, a clock maker who designed a timepiece that was robust enough to withstand the rigours of sea travel, and was thus able to substitute for the stars in the relevant calculations).

第一任观象大公约翰·弗拉姆斯蒂德就曾为此编制出了他那时候最精确的星体图最终的解决方法是由钟表匠约翰·哈里森提出的。他设计了一只经得住海浪颠簸﹑结实耐用的钟，并以它代替各种星体，进行相关的演算。

It is also known as one of the most poisonous naturally occurring substances.

它也被称为一个最自然发生的有毒物质。

The greatest stress is found at the location on the cross section where V is the largest.

最大应力出现在横截面上V为最大的地方。
