target fluctuation

According to researches, there are three useful methods about software data mining: target evaluation method, fluctuation degree method, center knowledge method.

提出了3种实用的软件数据挖掘方法：评价指标法，中心知识法，偏离度法。

Definition of Exchange Rate Target Area Fluctuation Based on Equilibrium Analysis

基于均衡分析的汇率目标区浮动区间确定

Using K as the evaluation amount of fluctuation of the pre and post net assets per share, listed firms from 2000 to 2002 as the study target, we analyse the related problems of the assets quality and the earnings ability of the listed firms.

以K值作为衡量调整前后每股净资产的波动幅度的指标，以2000-2002年上市公司3年的样本为研究对象，分析了我国上市公司资产质量及其与盈利能力的相关问题。

To analyze and evaluate the effect of target's RCS fluctuation on the performance of radar detection, a series of statistical models are introduced.

为分析和评估目标RCS起伏对雷达检测性能的影响，常用一些统计模型来描述目标RCS的起伏。

Assuming that the target RCS fluctuation characteristic is the Gaussian spectrum characteristic, this paper simulates the target RCS fluctuation characteristic by white Gaussian noise passing through a lowpass filter with Gaussian spectrum shape.

在假定目标RCS起伏为高斯形状频谱特性的前提下，将高斯白噪声通过一个高斯谱特性的低通滤波器来模拟目标RCS起伏特性。

The author discusses the defects of the existing primary model of exchange rate target area and puts forward a way to decide the exchange rate target area fluctuation based on equilibrium analysis.

本文分析了汇率目标区基本模型存在的缺陷，在此基础上提出以均衡分析为基础确定汇率目标区浮动区间的基本思路。
