Examples
- In the brief introduction to geographical information system ( gis ) , this dissertation proves that by combining reliable management with gis technology , presents a method which built the power structure model and math calculation model by using spatial data in a good interface between computer and user . this dissertation makes a number of target for calculating the distribution system , mainly aimed at circumstances which have an effect on power station repair , switch breaker , type of t connection , and double lines supply via the usage of system reliability calculation . at the same time , it provides the projected estimatio n when power station or transmission line will be added into the power system , and furnishes the theoretical information that the professional needs for power structure programming , design and equipment management
通过建立输变电设施管理信息系统( mis ) ，真实地反映出油田电网输变电设施的运行管理现状，为网络可靠性计算提供可靠的计算依据；在简述地理信息系统( gis )技术的基础上，论证了可靠性管理与电力gis技术结合的可能性，创立了在简洁的人机图形界面下利用空间数据建立网络结构模型及可靠性计算模型的方法；通过建立网络可靠性计算系统，进行了计及变电所检修影响、切换开关、 t接点及双回线供电情况下的可靠性指标计算分析，对油田电网及变电所(线路)的改(扩)建方案、增强性措施及接入系统的可靠性给予了工程评估，为电网规划、设计及日常的设备管理提供分析决策依据。 - And more aperture extension is achieved in this novel esprit - based two - dimensional angle estimatio n scheme using a uniform rectangular array of vector hydrophones spaced much farther apart than a half - wavelength . this proposed scheme and the attendant vector - hydrophone array outperform a uniform half - wavelength spaced pressure hydrophone array with the same aperture and slightly greater number of component hydrophones by an order of magnitude in estimation standard deviation
结合实际的应用情况，对矢量水听器构成的阵列进行了初步的探讨，利用本文前面部分所分析的基于单矢量水听器的方法，实现了阵元间距突破半波长上限的局限，并解决了角度估计的循环模糊问题，以较小的硬件代价和运算代价实现阵列孔径的扩展，提高估计精度。
