结点

The human moving system is defined as a rigid frame, which contains 19 articulate entities. Entity rotates around the father node and its son node is the father of another entity at the next level.

将人体运动系统视为一由19个实体构成的刚性框架系统，每一实体上的父结点绕与上级实体连接的关节点旋转，该实体另一端的子结点则作为下一级实体的父结点。

Firstly, several kinds of schemes were proposed according to the design demand. The best scheme was chosen after analyzing and comparing the schemes. The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced. The manipulative interface about the kinematics equation direct solution and inverse solution was completed with VC++ and the velocity Jacobian of displacement matrix was constructed using differential transform method. In the process of the trajectory planning based on robot's kinematics analysis, I propone a method by which we can get middle nodal point with normalizing factor in order to simplify our searching for these middle nodal points. In addition, I give these middle nodal points with actual physics signification. For eliminating contradiction between real-time and accuracy, I bring forward separately limit of error and reversal interpolation method. For decreasing calculation quantity, we resort to tri-spline interpolation in the articulation space.We analyse the work range of the robot by resorting to graphic means.

首先，作者针对机器人的设计要求提出了多个方案，对其进行分析比较后，选择其中最优的方案后用Pro/Engineer和AutoCAD软件进行了机器人模型结构设计；其次，进行了运动学分析，用D-H方法建立了坐标变换矩阵，推算了运动方程的正、逆解，运用VC++制作了正、逆运动学求解的求解界面；并且用微分变换法推导了速度雅可比矩阵；在基于机器人的运动学的轨迹规划中，通过在操作空间的规划，提出了归一化因子来求解中间结点，通过它可以使求解中间结点变得更简单，并且赋予这些中间结点实际的物理含义，对于规划中精确性和实时性的矛盾，提出了以误差极限法和反向插值法来解决的方法；为了减少规划过程中计算量，在关节空间进行三次样条插值；然后借助图解法进行工作空间分析，作出了实际工作空间的轴剖图。

Routing Information Protocol make every node know information of its neighbors.

正确的路由选择需要知道路由中结点的信息，路由信息协议使每个结点知道相邻结点的信息。

An example of a Markov chain is a simple random walk where the state space is a set of vertices of a graph and the transition steps involve moving to any of the neighbors of the current vertex with equal probability (regardless of the history of the walk).

举一个马尔科夫链的简单例子-----随机移动。随机移动的状态空间是由一组结点够成的图，而状态的改变是因为从当前的结点以相等概率的方式移动到任意一个相邻结点。（而这种移动是与原先的随机移动没有关系的。

Then, in the procedure of triangulation, we introduce the concept of front splitting and discontinus increasing, so that the procedure can be used to form triangular elements within muti-connected domains with arbitrary boundaries and nodes without any regularity.

然后，在将内部结点和边界结点连成三角形的阵面法中提出了生成阵面增长和分裂的概念，使得该方法能够适应于结点疏密程度变化很大的任意边界内的三角形网格的生成，并能够自动处理多连通域问题。

Reply: I think of FSBK offer be duplicated very likely to come over by the net inside school, we can look, basically the Information Industry, I consider as 20 years big metempsychosis, 35 years a truckle is answered, it is WT proposes form for the foundation next PC individual machine so a times, arrive next now, everybody considers as GLOG information an age that establishs for core before, now not so think, now is it is core with the person with the net inside school, it is node with the person with factitious ligament, before is information is node, now is with person node, because true so essence of life is collected, so this upgrades to what whole industry brings very big industry.

回答：我认为FSBK的提供很有可能被校内网复制过来，咱们可以看，基本上信息产业，我认为是一个20年大轮回，三五年一个小轮回，然后是WT为基础建构了PC个人机那么一个时代，然后到现在，大家以前认为是GLOG信息为核心建立的一个时代，现在不那么认为，现在是以校内网以人为核心，以人为纽带以人为结点，以前是信息为结点，现在是以人结点，因为真实所以精采，所以这个对整个行业带来很大产业的升级。

Stack will be the first to use infix form of the formula into the form of the suffix and then form the basis of the suffix from the beginning of leaf nodes corresponding binary tree structure Finally after by traversal of the tree, and the value of the subtree, that is, for every arrival a node, the value of its sub-tree has been calculated, when the reach the root node, the obtained value is the formula of true value.

首先利用堆栈将中缀形式的公式变为后缀形式；然后根据后缀形式，从叶结点开始构造相应的二叉树；最后按后序遍历该树，求各子树之值，即每到达一个结点，其子树之值已经计算出来，当到达根结点时，求得的值就是公式之真值。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
