Because of the nonuniqueness in the positional solution, it's not easy to test the performance of the coordinated control system. So the model of NN was built to convert the vector of the length of 6 jars into the vector of the position of the motion deck. It's fast and accurate for the lengthwise direction. The state space system model of the six degree freedom motion simulator was built by the equations of electrodraulic servo mechanism and the multi-body dynamics equation of the six degree freedom motion simulator,the vector of the length of 6 jars was the control variable.

本文结合六自由度运动模拟器的多体动力学方程和电液伺服驱动机构的特性，经简化得出了具有实际意义的六自由度运动模拟器整体系统的状态空间方程式，通过分析该系统的稳定条件和能控性，采用状态反馈对系统的状态方程式进行合理配置，从而建立了以运动模拟器杆长向量为控制变量的运动模拟器整体控制系统，并将该控制系统输出的杆长向量转换为位置向量。

A unit of length equal to either the width or the length of the hand.

一掌长，一掌宽与手掌的长或宽相等的一种长度单位

This experiment works on:1.prepare marrow cell chromosome samples;2.take pictures of chromosome in karyon by lens-check;3.Measure the length of chromosome short arm and long arm,calculate the relative length of frog chromosome and the arm index and the position of centromere,with the leven method of outside-body karyon pattern analysis.

本实验制备了骨髓细胞的染色体标本，并且通过镜检拍下一个细胞核中染色体的照片，用leven方法进行体外核型分析，测量每条染色体的长臂长与短臂长，并计算出青蛙染色体的相对长度，臂指数和着丝粒。

The results show that smaller height of reaction channel can shorten the time which reactants diffuse from channel to reaction surface, longer length of micro-channel can extend residence time of reactants on the catalyst surface, and consequently increase the methane conversion and hydrogen production. The pressure drop between inlet and outlet increases lineally with the increasing of length, while the height influences the pressure drop significantly when the height is less than 0.4 mm. Based on the overall consideration for the methane conversion and resistance characteristic generally, the suitable height of channel should be between 0.4 mm and 0.6 mm.

结果表明：较小的通道高度能够减小反应物在通道中的扩散时间，较长的反应通道长度能够增加反应物与催化剂的接触时间，甲烷转化率和产氢率提高；通道长度线性地影响微通道进出口压降的大小，而在通道高度小于0.4mm时，通道高度显著地影响进出口压降的大小；综合考虑微通道的重整性能和进出口压降等因素，通道高度在0.4~0.6mm之间较为合适。

Used for reeling set length's yarn to test whose linear density and length.

Finally, the relationship between group delay, linear region and cavity length of Gires-Tournois filters is analyzed, and the suggestion on how to choose suitable cavity length is presented.

最后分析了群延迟、线性范围与Gires-Tournois滤波器腔长之间的关系，指出了如何根据实际要求选择腔长的方向。

This paper extracted and analysed 11Math-Mophological Features such as Area, Perimeter, X-Length, Y-Length, Shape-Parameter, Lobation, Sphericity, Circularity, Roundness, Eccentricity and HoleNumber. Based on 40 species of insects which belonging to 8 Orders, 25 Families. And then ranks the accountability of 11 features each in insect identification while assessing their implication to insect taxonomy on levels of Order, Superfamily, Family and Species. More than those, also describes the kinship among the insects of various categories within the same level from the perspective of mathematical morphology through cluster analyses.
