That system could collect simulation signals from four routes ( the height of the combine harvester, the grain humidity, the grain temperature and the grain flux) at real time, digital signals from two routes (field speed and rotate speed of grain elevator ) and GPS differential signals.

该系统能够同时集割台高度、谷物水分、谷物温度和谷物流量等4路模拟信号以及地速和升运器转速等2路数字信号和GPS差分信号，并且能够每隔1秒钟向CF卡存储一次信息。

The model impacts a pair of tunable parameters on the tolerance relation derived from an IDT between objects by attribute values and a threshold on inclusion relation between subsets to form lower and upper approximations in the model for processing the table.

在该模型中，设定一对可调的参数使其作用于由IDT衍生出的限制容差关系，从而形成上下近似集。

And the evaluation effects of China's Stock Market's volatility by different ARCH models from different point of view are compared. In addition, by using two mixed distribution models, the leptokurtosis and fat-tail of stock return are examined. Based on the above analysis, an improved Laplace distribution model is proposed. Furthermore, the root generating non-Gaussian return distribution of the stock market ? is expounded from the perspective of both economy and capital market.

首先分别从分布和波动性模型出发，研究中国股票市场收益分布特征与波动性特征：从ARCH族模型出发，考察了中国股票市场波动性的异方差、集群性、杠杆效应以及长记忆性特征；从两个混合分布模型出发，结合随机模拟考察了收益分布的尖峰、厚尾和偏态特征，并提出了改进型LapJace分布。

Given the assumption of analysis-of-variance model, the text selection can be transformed to a linear parameter estimation problem, which can then be solved by a greedy matroid cover algorithm.

在方差分析模型的假设下，最优文本选择就转化为线性参数估计问题，相当于寻找拟阵的最小代价覆盖集，从而可通过贪心算法求解。

A new approach for packing the missing attribute value is presented based on the breaking point sets in the information system table.

在粗糙集理论的研究中，目前有一些关于遗失数据的填补方法，如均值法、大频率法等，但这些大都没有很好地与信息表这一表现形式的特点相结合，填补数据的质量较差。

First, TMA method for multistation, is presented using multi-bearings, frequency in different way including focus and contributed ways.

首先研究了一种基于多方位、频率测量的TMA方法，分别采用集中式、分布式等不同结构来实现。然后研究了多平台基于时延差、方位测量的TMA方法。
