可观测的

Therefore there exist the so called vacuum fluctuations. In the QED, for example, there exist the effects of zero-point oscillations of photons, the effects of vacuum polarization of electron-positron paris, and so on. They all could result in observable consequences , such as the anomalous magnetic moment of the electron, the spontaneous emission of atoms in excited states, the Lamb shift and the Casimir effect, which have been verfied in experiments.

例如，在量子电动力学中真空中存在着光子的真空零点振动效应，正负电子对的真空极化效应等等，它们都导致可观测的物理效果，如磁矩反常、激发态原子自发辐射、兰姆移动、卡西米尔效应等。

It has shown that the system is controllable, observable, and its stability may be gua...

证明该系统是可控的、可观测的，其稳定性是可以保证的。

System observability is examined and two necessary conditions for the system to be observable are obtained.

首先分析了系统的观测性，得出了系统可观测的两个必要条件。

The specific content of man-made earth satellite motion theory, power of observation and owned satellite operator, observation equipment and the establishment of such a number of observation points the content of .20 century, 60-70 years, have been used as a weather observation satellite launched high-altitude balloon, as the satellite observed the law of geometric measurement objectives of the United States launched TRANSIT .80 era satellites, it has several flights along different directions through the ring of satellites to address at any time, there will be a satellite-observable problems.

具体的研究内容有人造地球卫星运动理论、动力式卫星的观测及归算、观测仪器和观测点的设立等多项内容。20世纪60—70年代，曾用为气象观测发射的高空气球卫星，作为卫星几何测地法的观测目标。80年代美国发射子午仪卫星，它有几个沿不同经圈方向飞行的卫星，以解决任何时候都会有一颗卫星可观测的问题。

According to two factors between the observability and the stability in the paper, a practical phasor measurement unit configuration scheme based on weak voltage area surveillance and incomplete observability is proposed.

本文同时考虑系统可观测性和电压稳定性两方面因素，提出了一种基于电压薄弱区域监视的非完全可观测的同步相量测量单元配置方案。

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。

The supply chain coordination with sales effort effects is explored. This work designs a contract to coordinate the supply chain in case of observable sales effort; it proves that the usual contracts can never coordinate the supply chain, but a modified scheme can improve the performance of the whole system in term of inobservable sales effort.

分析了进取型供需链的协调问题，如果促销行为是相互可观测的，设计了一种特殊合同策略来协调该系统，如果促销行为相互不可观测，则证明了常见合同策略无法完全使系统达到协调，但适当的设计可以改善系统性能。

Time the city can be observed up to 2 hours and 40 minutes; followed by the sea there is no shelter material, while other cities are in the basin, the mountain block and more is not conducive to observation; Third, the total solar eclipse occurs when the sun altitude angle Zhoushan the largest observed the best results.

全市可观测时间可长达2小时40分；其次海面上没有任何遮挡物，而其他城市大都位于盆地，山体遮挡多，不利于观测；第三，日全食发生时，舟山的太阳高度角最大，观测效果最佳。

Identification of the surface starting from the photon far-field, and assuming that the relevant physical quantities of the medium are known.

假定介质的各种相关物理量都是已知的，光子密度是可观测的，识别介质的表面。

We find that model LBGs can have the same Two Point Correlation Funtion over the range of observable separations even though the cosmology and/or galaxy formation model are different. Moreover, with similar galaxy formation models, different cosmologies can result in both the same TPCF and the same PVD.

进而发现：(1)即使宇宙学和星系形成模型均不同，模型Lyman Break星系在可观测的尺度上也可以表现出一样的两点相关函数；(2)另外，不同的宇宙学模型可以预言相同的TPCF和PVD；(3)然而，不同的星系形成模型即使保持TPCF一样，也将预言截然不同的PVD。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
