( 5 ) analysis of data measured with multi - element regression , and optimized mathematics model of grain moisture measurement is brought forward based on contrast of several stat parameters . the particular operating of data fusion method based on parameter estimation is used . the validation is proved by increasing the measurement precision and reducing the ucertain factor ( 5 )采用多元回归分析的方法，对检测数据进行了分析，在运用各种统计参数进行比较分析的基础上提出了粮食水分检测的最佳数学模型。分析了采用基于参数估计方法进行数据融合的基本原理，验证了此方法对于减小不确定因素影响，提高检测精度的作用。
The research work is held on schedule ; the first sample machine was taken testing in foundry plant of tsinghua university in late of 1995 and confirmed systematical control thought and technical parameter ; it is proved that this system has high precision of moisture measuring and creditability that establishes good preparation for new research 研制工作如期进行，一九九五年底第一代试验样机在清华大学铸造厂进行试验，初步确定了系统的控制思路及各项技术参数，验证了自行开发的水分检测装置的精度及可靠性，为产品的样机设计打下坚实的基础。
The third generation sample was purchased by no . 1 foundry plant of dongfeng automobile company and passed identification in 1997 ; the experts gave high appraise : systematical moisture testing and control software belongs to pioneer in our country and fills up our black that has reached advanced level of 90s in developed country 第三代样机产品被东风汽车公司铸造一厂定购，并于1997年进行了鉴定，与会的专家给予了高度评价：系统的水分检测与控制软件属国内首场，填补国内空白，达到九十年代国际先进水平。
This paper researches the following questions : ( 1 ) testing rheology behavious of a kind of sample of the nuv cement slurry , which is solid - liquid suspension non - ncwtonian fluid . ( 2 ) getting the relation between the water content and the rheology behavious , and to obtain the singnificant formula in designing the revolving detector 本论文以水泥生料浆为例研究了以下几个方面的问题： ( 1 )非牛顿流体?料浆的流变特性， ( 2 )料浆的水分含量与流变特性之间的关系，得出对设计旋转式料浆水分检测头有意义的计算公式。
This paper presents a multisensor intelligent measuring system based on can bus , which measures parameters of the grain in storage : temperature and moisture content of the grain in storage , temperatures and humidity of the outside air and inside air respectively . the methods of information processing in the system are also importantly discussed based on this system . this paper introduces soft measurement technology , the same and difference between soft measurement and virtual instrument , and how to predict the state of grain condition according to the measuring data with fuzzy rules and fuzzy reasoning 本文即以一种基于can总线的集温度、湿度、水分检测为一体的多传感器智能化粮情自动检测系统为实例，着重对系统中的信息处理方法进行了研究，并介绍了软测量技术、以及它与虚拟仪器的相同点和不同点，详细阐述了其在系统中的应用及如何根据测量数据利用模糊规则库和模糊推理对储粮状态进行估计，最后提出了利用工程软件matlab进行粮情参数检测信息处理与图形化显示方法，给出了上述信息处理方法的软件流程和部分程序，提高了整个系统的可靠性，使得粮情判断与决策等信息处理具有较高的准确性。
