观测的

A frame is set up in this paper that the unit vector of the star is taken as Z axis of the frame, and all the constant gyro drifts of inertial navigation system are projected on to the frame .

如果建立一个以星体方向为Z轴的坐标系，并将陀螺漂移投影到该坐标系，文中将证明绕该坐标系Z轴方向的陀螺漂移是不可观测的，并分析由此引起的导弹落点误差。

The switching law is assumed to be unobservable Markov process.

对于切换律是可观测的情形，利用线性矩阵不等式和共同2次Lyapunov函数的方法，给出具有参数不确定的切换系统2次镇定的充分条件。

Copula function keeps unchanged within a regime, and the transitions are driven by an unobservable Markov Chain.

该模型的特点是，Copula函数在一个状态内是固定的，在不同状态之间的转移过程是一个不可观测的马氏链。

This is true whether your subject is a dim galaxy that can hardly be told from the blackness of space, or detail on the Moon or a planet where the light is almost blindingly bright.

这是事实，不管你观测的是一个仅能从天空背景中区分出来的星系，或是月面上的细节，或是一颗明亮的行星。

The observed light curve continued to track the〓Co decay until t～800 days. After day 800, the observed bolometric light curve had an excess above the decay line required by〓Co.

但在800天以后，观测的热光度曲线的下降变缓，且大约在900天至1200天有一目前的理论模型均无法解释的热光度&鼓包&。

Such rapid orbits mean the planets in question are close to their parent stars, and thus likely to be tidally locked.

如此快速的运行轨道意味着被观测的行星离它们的母体恒星很近，也就是说很有可能出现潮汐锁定的现象。

At last, aimed at the stochastic system in which the uniform target at the same periods is observed by sensors possessing different characters at multiple scales, we present a method of the multiscale representation based on unregular tree. We develop the multiscale stochastic model based on scale sequence at odd- and even-numbered scale and on different order trees.

针对不同尺度上具有不同特性的传感器在相同周期内对同一目标观测的动态系统，给出了一类系统基于不规则树结构的多尺度表示方法，并建立了基于尺度序列奇偶相间阶树、不同阶树的多尺度动态模型。

Key to these direct detections have been big telescopes and the latest technology to pick out a vanishingly faint planet from its host star's overwhelming glare.

这些直接观测的关键在于大望远镜和最新技术，用它们来从主恒星强烈的光芒中捕捉到行星微弱的几乎消失的踪影。

For fiatΛCDM cosmogonies withσ8 normalized by recent weak gravitational lens-ing observations, the best results are obtained forΩ0～0.3;Ω0≤0.2 leads to too large galaxy correlation lengths, whileΩ0≥0.4 gives too high mass-to-light ratios to match the observed TF relation.

对于平直ACDM宇宙学模型，根据最近的弱引力透镜给出的σ8值，条件光度函数模型给出了最佳值为Ω0～0.3；当Ω0≤0.2时，星系相关长度过大；而Ω0≥0.4则给出了太高的质光比，和观测的TF关系不符合。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
