Now the controllability theory in linear systems over the field R of real numbers has been heavily studied. This theory is efficacious for analyzing the characters which are determined by the value of physical parameters and system structure, nevertheless a practical system has a definite structure and has approximate, even unknown parameter sometimes because of a limit to experiment conditions, or a limit to making technology, the errors of observation. It is inconvenience for a linear system over the field R of real numbers to analyze the structure characters of a physical system, such as structural controllability.

目前，实数域上的系统的完全能控性理论研究已经很成熟了，它用于分析系统结构和物理参量的值共同决定的那些性能是有效的，然而，在工程中，由于实验条件或者制造工艺上的限制和观测上的误差，以及人为地对数据的近似处理，一个实际系统往往其结构是确定的，而参数只是近似的甚至未知的，实数域上的系统不便于分析物理系统的结构性质，如结构能控性。

Credible transmission of fire parameter is the key to improve the reliability of fire automatic alarm system.

火灾参量的可靠传输是提高火灾自动报警系统可靠性的关键。

On the respect of partially-premixed combustion research, we systematically studied the structure of partially-premixed flames in counter-flow and coaxial jet flow by using direct calculation and flamelet modeling.

在部分预混燃烧研究方面，本文结合火焰面模型和直接求解的方法，在对撞射流流场和同轴伴流流场中系统研究了部分预混火焰的结构特征，提出以预混燃料的当量比和当量混合标量耗散率作为描述部分预混火焰结构变化的参量的观点，并比较了它和非预混火焰的异同。

Moreover, to achieve better control, neural network based FLC's proposed for tuning FLC's parameters.

而且， 达到更好的控制，神经网络基于的FLC 的提议为定调FLC 的参量。

Establish the practical model of combustion rate about propellant, and formate the software for analog calculation.

与密爆测试中得到的燃速相比，能较好的消除药型尺寸带来的误差，可直接代入到内弹道方程组中计算炮口参量。

For different parameters, the diffraction patterns of the expression of the Fraunhofer diffraction are identical, indicating the correctness of the expression.

在各种参量条件下，近似解析式所表示的衍射图样与严格的夫琅和费衍射积分的衍射图样完全一致，这表明用此解析式表征远场衍射是正确的。

The second part is in uniform convergence conditions function series, function and parameter improper integral. We properties.

第二部分是在一致收敛条件下函数列、函数项级数以及含参量反常积分的性质。

Factor analysis is a very popular multivariate statistical analysis method. It can summarize some unobservable factors from the test results which can summarize most of the observed data. The factor analysis suggest the DP, furfuran and CO_X can be divided into insulation aging factor, while the hydrocarbon gas and hydrogen were divided into another group which can be called insulation fault factor. The result of the factor analysis

因子分析作为一种常用的多元统计分析方法，可从众多可观测变量中，概括和推论出少数不可观测的潜变量，用最少的因子去概括和解释大量的观测事实；本文将试验过程中90℃下油中溶解气体、绝缘聚合度、糠醛等参量进行因子分析，结果表明：绝缘聚合度、糠醛、CO_x被分为一类，代表绝缘老化因子：烃类、氢气、被分为一类，代表绝缘故障因子；因子分析结果与现场经验一致，相互印证，具有重要意义。

To compare the performances of the proposed method with those of the commonly used image fusion methods, such as the usual wavelet fuser, the intensity-hue-saturation fuser, and the principal component analysis fuser, the SPOT and the landsat thematic mapper images are used to perform the experiment. The results show that the balance between spectral characteristics preservation and high spatial resolution retention can be achieved at different levels in image fusion.

使用法国地球资源探测卫星图像和陆地资源卫星专题绘图仪图像，将该方法与传统的小波变换融合法、强度色散饱和变换融合法和主成分变换法进行对比试验，结果表明，该方法可以在细节保留和光谱保持两方面达到不同程度的平衡，在合理的参量组合下，融合图像的目视效果和统计指标优于传统融合方法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
