Thischapter proposes three concepts,i.e.,kernelled quasidifferential,star-kerneland star-differential,and establishes their operational properties.A sufficiencytheorem and a sufficiency and necessity theorem for a quasi-kernel being a ker-nelled quasidifferential are proven.Both the existence of star-kernel for a qua-sidifferentiable function and the existence of star-differential for a directionallydifferentiable function are established.The relationships between sub-and su-per derivatives and Penot differentials are discussed as well.

这一章我们引入了三个概念，即核拟微分，星核与星微分并建立了它们的运算性质；证明了拟核为核拟微分的一个充分条件定理及一个充分与必要条件定理；建立了拟可微函数星核的存在性及方向可微函数星微分的存在性并讨论了Penot微分与上、下导数的关系。

In 2006,LIU Xin-sheng et al.introduced the concept of star-edge coloring of graphs, a star-edge coloring of graph G is a proper edge coloring of G such that any path of length 4 in G is not bicolored.The star chromatic index of G,denoted byχ_s,is the smallest integer k for which G admits a star-edge coloring with k colors.

2006年，刘信生等提出了星边染色的概念，若图G的一个正常边染色满足G中没有长为4的路是2-边染色的，则称此染色是G的一个星边染色，使得G有星边染色的最小颜色数称为星边色数，记作χ_s。

In order to got the more accurate Guide Star(with star flag 0), the stars with magnitude brighter than 6.5 of J1991.25 Hipparcos catalog were chosen, after the rigorous epoch transformation, the J2000.0 Hipparcos sub-catalog was got, with the help of the information of Tycho-2 star catalog and SAO star catalog at the same epoch, the threshold of position precision is introduced, which can meet the precision of attitude determination in arc-second level.

在相同的历元J2000.0时刻，选取J2000.0 Hipparcos星表和Tycho-2星表中位置精度阈值在1角秒内的共星作为导航星，选取除导航星外的J2000.0 Hipparcos星表和SAO星表中位置精度阈值在1角秒内的共星作为辅助导航星，通过模拟星图识别失败个例分析提取冗余导航星，使其排除在导航星之外。

Orbiting a Red Dwarf Star Image of the Day Gallery Orbiting a Red Dwarf Star This artist's concept of a gas giant planet orbiting a red dwarf K star shows a planet has not been directly imaged , but its presence was detected in 2003 microlensing observations of a field star in our galaxy .

此图本意是拍摄一颗环绕红矮星K运行的由气体组成的巨大行星，但并未直接对其成像，不过该行星的踪迹在2003年针对银河系中恒星带的引力透镜现象进行观测时被发现。

Commercialize make the star turns into " special commodity " in the United States, sports star is very rich, if be arranged by the project, the richest some is ordinal it is rugger star, baseball stars, it is basketball star next.

商业化使球星变为&非凡商品&在美国，体育明星是十分富有的，假如按项目排列，最富有的依次是橄榄球明星、棒球明星，其次是篮球明星。

Constituted of the smoked wood, the fake star is not shining but we have to admit it has the shape of the star, besides, its size is much bigger than the real star in the sky. It deserves the name of "super star".

这颗星星同样由熏木构成，虽然不耀眼，但人们不得不承认它是星星的形状，而它的尺寸比起我们眼睛能看到的天空中的星星也足够可以称为&超级巨星&。

Because of the false star existence, the biggest polygon is not necessarily the optimum match, this study introduced the concept of voting algorithm to the stars of the matched star triangles, the star polygon who takes stars with high match rate as a right identification, thus removed the false star disturbance.

因为有伪星的存在，此时的最大多边形不一定是最佳匹配，本研究引入了投票算法的理念，对组成星三角的导航星进行匹配率统计，选取匹配率高的星多边形作为正确识别，从而排除了伪星的干扰。

One theory holds that the bright star is a massive supergiant, periodically eclipsed by two tight-knit stars inside a swirling, dusty disk. The second theory holds that the bright star is in fact a dying star with a lot less mass, periodically eclipsed by just a single star inside a disk.

这两个理论，一个认为亮主星是颗超巨星，周期性地被一个由尘埃围绕的密近双星系统所掩食；而另一个认为亮主星其实是颗已经流失大量质量的垂死恒星，而尘埃云中的伴星也只有一颗。
