双星

A Kalman filter is given to fit the systems. The feedback amendable technique of instrument errors and the accuracy assessment of fall points are also discussed.

论文建立了适用于SINS／双星组合导航系统的Kalman滤波模型，并研究了Kalman滤波模型中SINS工具误差的反馈修正方法以及弹载SINS／双星组合导航的精度分析方法。

The correlation between short period and weak magnetic field of binary pulsar and millisecond pulsar implies that these pulsars are the recycled pulsars of existing binary accretion process.

双星脉冲星和毫秒脉冲星的短周期和弱磁场相关性暗示这些脉冲星是存在双星吸积过程的反加速脉冲星。

By the country more the name is " state-operated factory of the 9th rubber ", 1963 brand once more more the name is " roc " card, take meaning for roc volant flying meaning, mix in that great leap forward however the times of the wind be current of Culture Revolution, roc not only not volant fly, drop into trough for a time instead, the edge that reached to go bankrupt.

双星集团的前身是民族资本家杨子生于1921年创办的，在青岛西镇的荒凉海滩上，置起十余间简陋的土瓦房，"维新染料厂"开工了，这就是双星集团最原始的生命。1955年被国家更名为"国营第九橡胶厂"，1963年商标再度更名为"大鹏"牌，取意为大鹏展翅腾飞之意，然而在那个大跃进和文革之风盛行的时代，大鹏不但没有展翅腾飞，反而一度跌入低谷，到了破产的边缘。

In general , ba stars belong to binary system , and their heavy - element overabundances are due to the accreting material from the companions ( the former tp - agb stars and the present white dwarfs ). carrying out a series of monte - carlo simulations , the changes of orbital elements of binaries are recalculated for wind accretion scenario of the total angular momentum conservation

研究表明，钡星应该属于双星系统，其重元素超丰来自双星吸积，它的伴星已经经历了s -过程核合成，而且由在以前发生的同其伴星(以前是agb星，现已演化为白矮星)的质量传输过程中，从伴星那里获得了富含重元素的物质，这样造成了钡星的重元素超丰。

W UMa systems are very common, comprising some 95 per cent of eclipsing variables in the solar neighbourhood.

相接双星的存在又十分普遍，在太阳系附近，95％的食双星都是W UMa型相接双星。

According to the characteristic of Beidou double-star positing system, this paper puts forward the optimal predication model of double-star position/SINS integrated system.

摘要根据北斗双星定位系统的特点，提出了北斗双星与SINS组合的最优预测模型。

Furthermore, Binary stars have been neglected in most studies of the integrated light of the stellar populations with the EPS methods. However in real clusters and galaxies over 50% stars are in binaries, and binary interaction can result in some important classes of objects, such as blue straggles and subdwarf B stars (sdB, also referred as extreme horizontal branch ) which contribute significantly to the integrated light.

另外，多数演化星族合成模型在对星族进行研究时没有考虑双星作用，而在真实星团或星系中50％以上的恒星属于双星系统，双星相互作用可以产生一些重要天体，例如蓝离散星和B型亚矮星，而这类天体对积分光谱有重要影响，因此本论文研究目的之二就是在演化星族合成模型中考虑双星作用。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
