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.

The first type, kamafugite, is plagioclasefree, consisted of Tirich phlogopite, melilite, leucite and nephelite. They have lower contents of SiO2 and Al2O3, but have high TiO2, CaO, MgO contents and K/Na and Mg# ratio whereas the second type, potassic trachybasalt, is abundant in plagioclase and contains no phlogopite, melilite, leucite and nephelite. They have higher SiO2, Al2O3,(Na2O+K2O), and lower TiO2, CaO, MgO, and K/Na and Mg#, in comparision to the first type of rocks.

钾霞橄黄长岩是一种不含斜长石，但普遍含有高钛金云母、黄长石、白榴石、霞石的岩石，全岩化学成分具低SiO2和Al2O3，富TiO2、CaO、MgO和高K/Na、高Mg#值的特征；钾质粗面玄武岩含有大量斜长石但是缺乏高钛金云母、黄长石、白榴石和霞石，全岩化学中SiO2、Al2O3明显高于前者，而TiO2、CaO、MgO、K/Na和Mg#值要比钾霞橄黄长岩低。

Virtual bone dragons posture lightsome, action quick, easy to grab a pair of long arms and hands, and long and narrow jaw bone.

In keeping with his size, his whip was of Lilliputian proportions, being made of a stick about two feet long and a thin rope of the same length.

他那鞭子很小，是用两尺长的木棍系一根同样长的细绳做成的，同他的身材倒还相配。

But in consideration of the limitedness and insufficiency in practicing the theory, this research still needs development and improvement.

由于本人水平有限，课题研究时间不长，提出的一般模式有待长时间的检验和完善，仍有一些问题有待深入研究。

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。

High oil absorption resins of higher n-alkyl acrylates modified cotton linter were synthesizedby supension graft copolymerization. The effects of the ratio of n-alkyl acrylates to linter, the kinds and amounts of crosslinker, the amounts of initiator, as well as reaction temperature and time on oil absorbency were investigated.

以棉短绒为基材，丙烯酸长链酯为单体，双丙烯酸二元醇酯为交联剂，采用悬浮接枝共聚法合成了高吸油性材料，考察了棉纤维与单体的投料比、交联剂种类与用量、引发剂用量、聚合反应温度与时间等因素对该材料吸油性能的影响，得到了不同丙烯酸长链酯与棉纤维接枝聚合制备吸油材料的最佳工艺条件。

One chip is verified by these Litho Rules, we analyze the result, and find the bottle neck : first the runtime, for mask simulation cost long runtime.

并且基于实际的chip，分析了光刻规则在实际设计流程中的瓶颈：1）运行时间长，版图模拟时间长 2）内存消耗大。

First and foremost, we exposed just eight crew members — we typically flew with a pilot, copilot, loadmaster, and a second loadmaster who also acted as a scanner — and only two aircraft to the enemy threat, as opposed to three aircraft and eighteen crew members had we used the older aircraft.

第一个也是最首要的，相对于旧型号飞机我们要用3架飞机和18名机组成员执行任务，我们只有8名机组成员——飞行时我们的标准组成是一名驾驶员，一名副驾驶，一名装卸长，还有一名装卸长助手，他通常也扮演巡视员的角色——和两架飞机暴露在敌人的威胁里。
