1.Comparative Implementation of AOP and OOP on GoF23 Observer Design Pattern
GoF23中Observer设计模式的AOP实现与OOP实现的对比
2.At first several common methods are studied deeply such as U-I observer I-n observer U-n observer and low pass filter(LPF) observer and the advantage, short-coming are analyzed.
首先详细分析了几种常用的观测方法:U—I观测法,I—n观测法,U—n观测法以及低通滤波器观测法,并分析了它们的优缺点。
3.It is pointed out that the Coriolis force upon a particle observed by an observer on a rotating disk depends only on the rotation of the observer and is independent of the rotation of the disk (i.e., the revloution of the observer).
指出了转盘上的观者在观测一个相对于他运动的质点时，该质点是否受到科氏力只取决于该观者是否有自转而与转盘的转动（即观者的“公转”）无关．
4.So far China has sent 522 military observers, liaison officers or advisers and 800 men in two batches from engineering units to the UN peace-keeping operations, including the United Nations Truce Supervision Organization (UNTSO), United Nations Iraq-Kuwait Observation Mission (UNIKOM), United Nations Transitional Authority in Cambodia (UNTAC), United Nations Mission for the Referendum in Western Sahara (MINURSO), United Nations Operation in Mozambique (ONUMOZ), United Nations Observer Mission in Liberia (UNOMIL), United Nations Observer Mission in Sierra Leone (UNOMSIL) and United Nations Mission in Sierra Leone (UNAMSIL).
至今为止，中国已先后向"联合国停战监督组织"（UNTSO）、"联合国伊拉克-科威特观察团"（UNIKOM）、"联合国柬埔寨临时权力机构"(UNTAC)、"联合国西撒哈拉公民投票特派团"(MINURSO)、"联合国莫桑比克行动"(ONUMOZ)、"联合国利比里亚观察团"(UNOMIL)、"联合国塞拉利昂观察团"(UNOMSIL)和"联合国塞拉利昂特派团"(UNAMSIL)等多项联合国维和行动派出军事观察员、军事联络官和军事顾问共522人次，派出工程兵部队两批800人次。
5.The comparison between estimation performance of the PI observer and Luenberger observer shows the better performance of the former.
仿真结果表明 ,比例积分观测器的估计性能优于常规 Luenberger观测器
6.Current was the input of observer, and gap position can be got from observer.
采用电流作为观测器的输入,通过观测器得到气隙位置等状态量。
7.To investigate the problem of whether a single p assive observer can locate maneuvering emitter through its bearings and bearing s changing rates. We introduce algorithms of maneuvering target tracking by rada r named adjustable noise level (ANL) method, interacting multip model(IMM) metho d and by introducing maneuvering target model such as singer model, Constant Acc eleration(CA) model, two algorithms of single observer passive tracking maneuver ing emitter using bearings and its changing rates were studied.
针对单站无源定位中对于机动辐射源利用角度及其变化率能否定位的问题,引入雷达对机动目标跟踪的多级噪声自适应(ANL)法和交互多模(IMM)方法,以及机动目标运动模型如Singer模型、匀加速模型等,研究并提出了两种对机动辐射源利用角度及其变化率进行单站无源跟踪方法。
8.By using the Lyapunov stability theory,the gain of the observer could be obtained by solving a linear matrix inequality(LMI) in Matlab LMI toolbox,which solves the unstable problem of the adaptive speed observer using pole-placement technique.
应用Lyapunov稳定性理论,观测器的增益借助于Matlab中LMI工具箱求解一线性矩阵不等式得到,它解决了采用极点配置的自适应速度观测器存在不稳定区域的问题。
9.A reduced-order state observer and a control law based on the observer are designed.
建立了相应的数学模型，并在此模型的基础上，设计了降维状态观测器和基于观测器的反馈控制律。
10.The CAAC shall nominate a person or persons to attend meetings of the National Aerospace NDT Board with Observer status. The Observer shall not have voting rights.
中国民航总局(CAAC)推荐一名或几名代表，以观察员的身份参加航空航天无损检测认证部的会议。观察员无表决权。
