Based on Phylogenetic analysis of sequences from these 10 phytoplasmas using PAUP (phylogenetic analysis using parsimony) software, these phytoplasmas could be classified into five groups. These phytoplasmas groups and strains were: group 1, sweetpotato witches' broom, mainland China strain of sweetpotato witches' broom, peanut witches' broom and Ipomoea obscura witches' broom; group 2, loofah witches' broom; group 3, elm yellows; group 4, rice yellow dwarf and sugarcane white leaf disease; group 5, New Jersey strain of aster yellows and western strain of aster yellows.

从spacer序列堆衍的亲缘演化树显示这10种植物菌质体可分为5群：第一群，甘薯簇叶病、甘薯簇叶病、花生簇叶病及细花牵牛簇叶病等菌质体；第二群，丝瓜簇叶病菌质体；第三群，榆树黄化病菌质体；第四群，水稻黄萎病及甘蔗白叶病菌质体；第五群，翠菊黄化病菌质体。

介绍了煤矿单体液压支柱维修现状和一种用于单体液压支柱拆卸的专用拆卸机械，讨论了该机的结构组成、工作原理、液压系统，适应工作条件，主要特点，指出该机所解决的技术问题以及采用该机可达到的目的。

Introduces a type of special honer repairing hydraulic support cylinder using coal mine and other mine,main discuss its composing of hydraulic system,working principle,technics process,electrical control system and relation about each other lock moment,beeline move forword timing method,and its characteristic, attainability purpose using this machine.

介绍了一种用于煤矿或其他矿山的单体液压支柱维修专用珩磨机，重点讨论了该机的液压系统组成、工作原理、工艺过程、电气控制系统、运动互锁关系、直线进给调速方法以及特点，采用该机可达到的目的。

The most important of them are position sensors and distance sensors. This paper presents one method to compute the change of joint angles in chain using the information from position sensors, as well as another method to compute the six degree-of-freedom offsets between two connection plates using IR sensors among the automatic docking process. These computation methods provide some theoretic sustain for self-reconfiguration.

论文提出利用位置传感器感知的模块连接角信息计算对接过程中模块的相对位置和角度变化，还提出利用红外传感器的感知信息计算进行对接的模块两个连接面板之间六自由度方向的位置偏移量，这些计算方法为实现模块化机器人自动重组提供了理论支持。

In the aspect of the sexual difference, the tradition females are tended to use Chinese autonym. The females used more picture signs than the males, such as sign. In using picture sign aspect, the males does not like the females using the emotional pictures, they preferred charcters.

以性别来说，传统女性偏向使用中文本名，且女性相较於男性会使用较多的图像符号，男性在使用图像符号时，不若女性那般会使用直接的情绪性图像。

By using the solutions of a new auxiliary elliptic equation,a direct algebraic method is proposed to construct the exact solutions of some nonlinear evolution equations.The main difference between this method and previous auxiliary elliptic equation methods is that the balance order becomes smaller after using the new auxiliary elliptic equation.Therefore,the derived algebraic equations are greatly simplified.

利用一个新的辅助椭圆方程将求解非线性发展方程精确解的问题转化为一个代数方程组进行求解，与已有的辅助椭圆方程法的主要不同是，应用这一新的辅助椭圆方程后降低了平衡次数，减少了所得的代数方程组的个数和方程的项数，从而大大地简化了代数方程组的求解。

Based on the chemical equilibrium flow assumption, the electron density at the exit of the nozzle is determined using the minimum free energy rule. A numerical model based on auxiliary difference equation is derived to simulate the plasma in the time domain and the calculating results are compared with that using Z transform.
