查询词典 simulation

Firstly, the transient stability of the modes by which some kinds of huge power suppliers are connected with AC power grid is analyzed and compared in detail; then a detailed transient stability simulation of a certain large-scale demonstration system is performed; finally some helpful conclusions are obtained: in the general situation, the bundling power transmission mode is favorable to increase the stability of sending system; if it is helpful to evidently increase the inertia of the equivalent leading group, the mode that connects the huge power supplier with sending system will be helpful to enhance the stability of sending system, however it is necessary to perform simulation and analysis while these principles are applied to FACT systems.

首先从机制上对几种大电源接入交流系统方式的暂态稳定性进行了详细的分析和比较；然后对大型算例系统进行了详尽的暂态稳定仿真；最终得出了一些有用的结论：一般情况下，打捆送电方式有利于提高送出系统的稳定性；如果有助于显著增加领前群的惯量，则与送端系统相联的方式也有助于提高送电系统的稳定性，但仍要结合具体系统进行分析。

The simulation outcome demonstrates that various control measures after April 20,2003 in Beijing and the public holidays starting from May lst to May 5th have a significant impact on containing the epidemic situation. The most dangerous days, around April 27, when the number of uncontrolled SARS patients in the society reached at its peak, can also be calculated. The SARS infectiousness number newly reported in Beijing has been at a low level since May 20. But simulation experiments describe that it may fluctuate with import of SARS infectiousness from outside Beijing, weakening of quarantine, more social activities, and so on.

同时应用动力学模型，对北京的SARS疫情进行分时间段的模拟与SARS实施控制因素影响分析，结果表明，2003—04—20以后一段时间内实行的各种控制措施，以及5月1日—5月5日的长假对于北京SARS疫情的控制是非常有效的；而4月27日左右北京市社会上未得到有效控制的SARS病人数达到高峰，是最危险的时期。5月20日以后，北京的SARS疫情基本保持在低发的平台期，但是如出现较多的外来SARS病例输入，而内部隔离强度又减弱、社交活动增加等情况下，北京SARS疫情可能会有一定程度的波动与反弹。

The concept of digital life was first presented in computer simulation experiment by Thomas.S.Ray. Based on it, the theory knowledges were introduced such as complex adaptive system and Agent model-building. Then two kinds of different digital lives and their coexistence environment were constructed. Nature lives' most foundational biological phenomenas like reproduction and annihilation were simulated. The interactive behavior between individual and community was observed by visualization windows. Finally, the inscrutability and emergence of the results were attained, and the simulation for two digital lives with Swarm was accomplished.

Visual Rice Growth Models system represented an effort to design crop modeling software with object-oriented paradigm and to organize classes in system with model-document-view architecture. Firstly, the crop-environment system was abstracted as many subsystems and physiological processes with object-oriented paradigm while many classes were established to simulate the behaviors of these subsystems and physiological processes. In VRGM, the document-view architecture in Visual C++ was extended as model-document-view architecture for agricultural integrated system. In the model-document-view architecture, document gets the final simulation results by manipulating the models classes and acts as a communicating intermediacy between model and view. Views display the simulation results and translate users' operation and data entering to document. The architecture separates the domain models, data management and user interface.
