查询词典 binary star

For getting the major characteristic edges without confusions by undesired structures like muscle edges, we integrate a star-like edge detection filter named "Asterisk Filter" with the Canny Edge Detection in the image preprocessing. In addition, we also propose a new contour tracking method named "One-Pixel Rolling Ball Contour Tracking" for getting the boundary information in a binary image which is a link-list data structure. Instead of using a regression curvature estimator, PCA is used for better curvature estimation from a discrete bony contour.

为了从影像上取得骨头特徵边缘，将不重要的肌肉视为杂讯滤除，我们引用一种星形滤波器－Asterisk Filter，搭配Canny边缘检测法，做为这类影像的前处理；另外，为了将骨头的边缘精确地追踪出来，我们提出滚球边界追踪法，来对二值化影像进行边缘追踪，藉此获得边缘的串列资料结构；我们采用以主成分分析(Principle Component Analysis，简称PCA)取代原本以回归方法来计算的曲率，以取得更佳的曲率估测值，其可提高计算之参数的准确性。

But that's not a totally fair comparison, because Spica is not just one star, but a spectroscopic binary.

但那并不是非常公正的比较，因为天门星不只是一颗星，而是可用分光镜看见的双体星。

Such a supernova is thought to be the result of the explosion of a small and dense star - a white dwarf - inside a binary system.

这一类超新星被认为是双星系统内的一颗小而致密的恒星——白矮星——的爆发所致。

The greenish glow to the lower right of the Rho Ophiuchi cloud comes from dust surrounding and heated by the hot young binary star Sigma Scorpii.

该绿色辉光向右下方的rho ophiuchi云来自周围的尘埃和加热炎热年轻二进制明星西格玛scorpii 。

The most convincing evidence of black holes comes from research into binary star systems.

黑洞最有说服力的证据来自对双星系的研究。

For centuries, astronomers had not been able to figure out the nature of this "eclipsing binary system," in which a bright naked-eye star is eclipsed by a companion object every 27 years.

一个多世纪来，天文学家一直没搞清柱一&食双星&的性质，这颗肉眼可见明亮恒星，以27年的周期改变光度。

Binary systems are not rare in a galaxy, not worthless objects either for a distant observator, for they will sometimes perform a astronomical phenomenon called occultation, that one star's radiance covers the other and makes the luminance of the whole system change regularly.

双恒星在星系内并不少见，对于遥远的观测者来说也算值得注意的对象，因为它们会发生互掩，一颗星的光芒盖过另一颗的，从而导致整体的亮度时明时暗，周期变化。

The time at which an eclipsing binary variable star is at its minimum brightness is one example of something which is frequently given in the form of a Julian day number.

一个食变双星亮度最低的日期就是经常用儒略日来公布的。

Epsilon Aurigae is a visually bright, eclipsing binary star system with a period of 27.1years.

柱一是明亮的食双星，互绕周期为27.1年。
