查询词典 observer

However, unlike the light source relative to the rest of the observer to see is the colorless astigmatism, and the light source relative motion of the observer to see is the red-shift light ( achromatous astigmatism occurs redshift of red-shift light ); Although the different inertial reference frame of the observer can see the speed of light, after the Lorentz transformation is the same as after c; but a different observer are exposed to the light energy is not the same achromatous (astigmatism energy and achromatous astigmatism occurs after the red-shift of red-shift of the light energy is out of the same ).

但是，与光源相对静止的观察者看到的是无色散光，而与光源相对运动的观察者看到的是红移光（无色散光发生红移后的红移光）；虽然，不同惯性参照系的观察者看到的光速，经过洛伦兹坐标变换后都一样为c；可是不同的观察者所承受到的光能量是不相同的（无色散光的能量和无色散光发生红移后的红移光能量是完全不相同的）。

In this paper, a parametric approach for the design of Luenberger observer is proposed, and the problem of robust Luenberger observer design for systems with parameter perturbations is then considered based on the criterion of minimum observer condition error. A simple and effective algorithm is given.

本文首先提出了Luenberger观测器设计的一种参数方法，然后根据使观测器条件误差为最小的准则，考虑了具有参数摄动的系统的鲁棒Luenberget观测器设计问题，给出了简单、有效的算法。

A torsional oscillation observer based on the general observer was discussed to estimate the speed of the turbine generator. The dynamic characteristics of standard Luenberger observer with quantization effects were studied by Lyapunov stability criterion. It is concluded that the state estimate error can not asymptotically converge to zero in-the-large in presence of quantization effects.

讨论了基于状态观测器的汽轮机轴系扭振测量方法，采用李亚普诺夫稳定性判据分析存在量化效应的条件下标准龙贝格观测器的动态特性，指出由于数字系统中的有限字长效应会使观测器的跟踪性能恶化，估计误差不能在大范围内渐进收敛。

The packed planes imply a cramped space (as John Locke's "Private Room of Mind"), either overly lit or too dim because of camera flash, and the observer behind the camera. The flat square disarranges the domain allotment between subject and object or the observer and the observed. The lack of depth gives the observer a superior status as a judge in a secretive trial that has been carefully arranged by the artist. The scene provokes a lot of doubt in the mind of the audience and they feel they are exiled.

尹朝辉的作品多以拥挤的画面象征忧郁狭小的房间（暗喻洛克John Locke的「心灵所在的私室」），光线过亮或不足、强烈急促的光影表现，隐喻了闪光灯和观察者的存在，压平的四方造型拉近且打乱了主体和客体／观察者和被观察者的场域分配，毫无景深的视觉提示则赋予房间内的主动观察者更高阶的审判者的地位，但艺术家刻意营造的匿名性却又将这一连串的审判过程私密化，徒留给被动观察者一连串的疑问，以及成为局外人的被抛弃感。

So far, the ordinary observer; an extraordinary observer might have seen that the chin was very pointed and pronounced; that the big eyes were full of spirit and vivacity; that the mouth was sweet-lipped and expressive; that the forehead was broad and full; in short, our discerning extraordinary observer might have concluded that no commonplace soul inhabited the body of this stray woman-child of whom shy Matthew Cuthbert was so ludicrously afraid.

这只不过是用普通人的眼光看，如果是目光更敏锐的人来观察，便能发现，这个女孩儿长着尖尖的下巴，棱角分明，两只大眼睛里充满了朝气与活力，嘴唇线条优美，长得可爱逗人，藏着丰富的表情，前额宽阔——总之，这位有眼力的观察者可以得出下面的结论：这个无家可归的女孩身上蕴含着一种与众不同的气质。

The bow is centred on the shadow of the observer's head, or more exactly at the antisolar point (which is below the horizon during the daytime), appearing at an angle of 40°–42° to the line between the observer's head and its shadow.

船头是集中在阴影中的观察员的头，或更确切地说在antisolar点，出现在角40 °-42 °之间的界线，以观察员的头部和自己的影子。

A back electromotive force observer is constructed to acquire the information of speed as well as acceleration. By selecting the time constant or observer gain properly, the current command reduction characteristics can be adjusted freely in some range.

其中的反电动势观测器能方便地获得速度和加速度信息，通过适当调整观测器的时间常数和增益，就能使驱动电流指令值在一定范围内自由调解以达到控制目的。

A reduced order state observer is adopted to reconstruct the rotor flux component, and the poles of flux observer are assigned properly by pole assignment algorithm to satisfy the performance criteria of system and to get the purpose of observing flux.To start with the basis concept of space vector, the paper analyzes the relationship of stator phase voltages and voltage vectors in space.

磁通观测器采用降维观测器，仅对转子磁通分量进行重构，并通过极点配置算法，合理配置观测器的极点，使观测器满足系统的性能指标，达到磁通观测的目的。

该文给出超临界机组协调受控对象的一种实用数学模型，采用观测器预估燃煤的热值，设计一种基于增量式函数观测的状态反馈+串级PID+智能控制+热值补偿的综合型协调控制系统。

An optimal path planning algorithm of the observer is proposed in this paper, which is based on the dynamic programming. Based on the data measured at the current stage, the optimal moving direction of the observer at the next stage is calculated aiming at the maximum area of the target feasible region convergence.

该算法在当前测量时刻所测数据的基础上，以目标位置可行域收敛面积最大化为目标，分析出观测站运动到下一测量时刻的最优运动方向，从而达到缩短定位时间和抑制定位误差的目的，实现整个测量路线的最优化。

The antiquarian refers the vase to the second century.

古董收藏家认为这花瓶是公元2世纪的文物。
