双星

These events include two kinds of stellar explosions:(1) nova explosions, in which one of the two members of a binary star system hurls dust and gas into space;(2) much more violent supernova explosions, in which a star collapses, then throws off most of its matter.

这些事件包括两种类型的恒星爆发：（1）新星爆发，双星系统中的一员将气体和尘埃猛烈抛入太空；（2）更为猛烈的超新星爆发，那是一颗恒星崩溃时几乎把它所有物质都抛出去了。

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。

Woman the running shoes on wave of ginger of champion of 5000 meters of worlds, Dong Yanmei foot is design of personnel of double star research and development.

女子5000米世界冠军姜波、董艳梅脚上的跑鞋就是双星研发人员设计的。

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。

A very bright, variable, double star in the constellation Aquila, approximately15.7 light-years from Earth.

牵牛星，河鼓二天鹰座的一颗非常明亮的，易变的''。'双星'。''，距地球约15.7光年

A double,eclipsing variable star in the constellation Perseus,almost as bright as Polaris.

大陵五，英仙座β星，恶魔星英仙座的双星，几乎与北极星一样明亮

Master sheep are generally variable star what time you change the time the sheep must switch into violent posture point to a bloody rampage in hand to let him change faster sheep.

法师一般都是双星变羊什么的这时在变你羊的时候一定要切换成狂暴姿态点开血性狂暴手要快再让他变羊。

On the basis of analyzing the errors of Beidou system ,we present a new scheme,called distance-discriminance location,to use in the midcourse guidance of cruise missile.

在分析北斗系统误差的基础上，提出了巡航导弹中制导基于北斗双星系统的距离判别定位的新方法，并探讨了其工作方式和关键问题。

In this paper, the basic mathematical model was derived by means of two methods, the first is the twostar positioning algorithm in celestial navigation theory and the second is based on the gyro dynamics theory. The results from these two methods are identical and therefore are correct. The latitude is equal to the elevation-angle of the polar gyro. The course is the ideal output from the sensor fitted to the outer gimbal. The longitude is a function of the equator gyro's azimuth and elevation angles.

本论文用天文导航中的双星定位法和经典的陀螺力学原理两种方法建立了ESGM的基本数学模型，并且得到一致的结果，说明所建模型是正确的，即载体的纬度等于极轴陀螺主轴相对水平面的高度角，载体的航向等于极轴陀螺外环轴上角度传感器的理想输出，载体的经度是赤道陀螺的方位角和高度角的函数。
