分析的准确性 meaning in English
precision of analysis
Examples
- A complicated model has been setted up to simulate the sodium flow in hot and cold plenum under normal condition and reactor scram of cefr , using fine grid to simulate the reactor internals and important equipments . this slove the problem that the simulation grids are very coarse in the precedeable work , and the accuracy and reliability of the simulation are improved . 4
对cefr的额定工况和全厂断电工况下的堆内过程进行了复杂的数学建模和分析，使用了精细的六面体网格，对堆内构件和重要的设备进行了三维的数值分析，克服了以往数值模拟中网格过于粗糙的缺点，使数值分析的准确性和可信度大大提高； 4 - The set of these eigenvalues can be regarded as the eigenvalues of primary system approximately . this method not only can control the scale of the block - decoupling subsystems , but also achieves the reduced - order eigenvalue calculation for multi - machine power system . so this method can avoid the dimension disaster in the qr and calculate all the eigenvalues of large power system with the effect of damping windings considered
这一方法可以控制分块解耦子系统的规模，实现多机系统特征值的降阶计算，避免特征值qr算法的“维数灾难” ，同时为采用计及发电机阻尼绕组作用的详细模型计算大型电力系统的全部特征值、提高电力系统小扰动稳定分析的准确性提供了一种方法。 - Almost there is n ' t one kind of data can reflect fully it ' s scale and quality . even it has n ' t been brought into the statistics of the countries " foreign trade . this bring undoubtedly much inconvenience to relevant study , especially the accuracy of microcosmic analysis is worth deliberating
然而，边贸发展历程与双边关系并不合拍，几乎没有一种数据能充分反映其规模与质量，甚至根本没有将其纳入两国外贸统计，这无疑为相关研究带来了诸多不便，尤其是微观分析的准确性值得推敲，故而，人们通常从宏观角度进行推测与评估。 - The paper analyses the necessity of the investment risk analysis of chinese petroleum enterprises in dint of the development about the same business in home and overseas and gives a new method - monte carlo simulation method through connecting with general theories of investment risk analysis and basing on analyzing the problems which lie in the investment risk analysis and management and by grounding on original evaluation guideline system of investment risk analysis and decision - making model . the merits are that the method not only embodies uncertainty of risk elements but also makes up the limitation rooted in underestimating influence extent about all of risk elements by com bining original break even analysis and sensitivity analysis . the method perfects deeply investment risk analysis system and improved the accurateness of investment risk analysis
本文结合石油企业投资风险分析在国内外的发展状况，分析了我国石油企业进行投资风险分析研究的必要性，结合投资风险分析的一般理论，在分析我国石油企业目前投资风险分析与管理方面所存在的问题和我国石油企业原有的投资风险分析评价指标体系与决策模型的基础上，根据我国石油企业实际情况，引入蒙特卡罗模拟方法，充分体现各风险因素的不确定性，使之与原有的盈亏平衡分析、敏感性分析相结合，以弥补原有石油企业投资风险分析决策模型对各风险因素的影响程度考虑不足的缺陷，进一步完善投资风险分析系统，增强石油企业投资风险分析的准确性，并将其应用于辽河油田冷家西部开发方案中。 - In order to be better used in faults simulation and analysis , the accurate of model needs to be improved . the research of marine diesel engine generator system simulation includes modeling and simulation results " analysis . based on mechanism of the marine diesel engine power system , and according to the marine power system of yunhe vessel , this dissertation sets up a simulation model of yunhe generator system
由于船舶电力系统模型是轮机模拟器中电站部分的核心，为了使建立的模型精度更高，更具有系统故障仿真和分析的准确性，本文从船舶柴油发电机系统的机理出发，应用电力系统稳定性理论，结合云河轮电力系统，在matlab软件平台上，建立了云河轮柴油发电机系统的模型，并对该系统进行了仿真运行和分析。
