Examples
- Adopting different cfvm concretes with different workability were achieved while the same proportioned mortars and the same kind of coarse aggregates were used . 3
用障碍坍落度试验测试混凝土的工作性发现，砂浆填充系数不同时，用同一种砂浆和粗集料可配制不同工作性的混凝土。 - Discussing on the present development of macroeconomic early - warning , this paper points to the present problems about macroeconomic early - warning ; at the same time , it introduces the theory of macroeconomic early - warning and discusses on the problems , such as , the design of early - warning ( e - w ) indexes , the choice of e - w model , and the decision of e - w deadline . by analyzing two methods : artificial neural network ( ann ) and rough set ( rs ) , we connect the theory of rough set with artificial neural network and build the model of macroeconomic early - warning system based on rough set and artificial neural network ( me - rsann ) . on the basis of it , the paper introduces the basic content about me - rsann and researches the realization of early - warning ways including the structure model of ms - rsann , resolvement of problems during operation of early - warning model , the design of specific early - warning deadline , and so on ; finaly , using statistics data , we carry out quantitative analysis according to the model of me - rsann
本文首先对国内外宏观经济预警进行概述，提出目前在宏观经济预警方面存在的主要问题；并在此基础上阐述宏观经济预警理论体系，讨论了预警指标的设计、预警方法的选择和预警警限的界定等问题；在分析和讨论人工神经网络( ann )预警方法和粗集( rs )理论方法的优势互补后，建立了基于粗集与神经网络相结合宏观经济预警系统模型，详细地论述了基于粗集-神经网络预警方法的基本原理，研究了预警方法的实现，其中包括建立粗集-神经网络预警的结构模式、解决粗集-神经网络预警操作中的问题、提出具体的预警警限的界定方法；最后，利用我国的统计资料，对ann预警和粗集-神经网络相结合预警方法进行了实证分析和比较研究。
