链表

The dissertation advances multi-linked list, which denotes subroutine structure and subroutine calling relationship, and is displayed by the way of hierarchy structure tree. And according to this, the dissertation designs an algorithm to abstract and adjust the code structure and flows.

提出了子程序结构与子程序调用关系的多重链表和层次结构树表示方式，设计了代码结构与流程提取和调整算法。

In the CAD system for progressive dies, the method is introduced to automatically generate geometric models of stampings through inputting the product drawings by AutoCAD and picking-up the entity information from DXF files and programming with ObjectARX and C＋＋ language, at the same time, generating algorithm of close contour lines and unidirectional chain-table structure are used to express the models of stampings, the class and direct judgment of contour lines are realized and the entity existing side is judged by analytical geometry, which efficiently solves the problem of automatic input of drawings of stamping and providing information of process planning and mold design.

在级进模CAD系统中，将产品的图形信息以AutoCAD直接绘图形式输入到计算机中，从AutoCAD的图形交换文件中提取信息，采用面向对象的二次开发工具ObjectARX和C＋＋语言编写接口程序，并通过封闭轮廓的生成算法自动生成冲裁零件的几何模型，且用单向链表的形式加以表达，同时对冲裁零件图形的轮廓进行分类与走向判定，采用简单的解析几何方法对实体存在侧进行判定，有效地实现了零件图形的自动输入，为级进模CAD系统的工艺计算和模具工作部分的设计等提供了必要的信息。

There's, however, a problem if you want to append a node in a shared linked list, for example.

还有的，但是，一个问题，如果你想在一个共享的追加链表节点，例如。

Long int readData(Buffer * pBuffer,/* pointer to the abstract buffer */ byte * pOutput,/* pointer to the output byte array */ long int offset,/* offset of the output byte array */ long int arrayLength /* size of available output byte array */){ while (there is something more to read and there is room for output){ read from the first memory block; if (the first memory block is empty){ delete the first memory block from the linked list and free its memory

在 清单 5 中，该函数销毁性地从 pBuffer 所指向的抽象缓冲区最多读取 arrayLength 个前导字节，并在内存块变为空时从链表中删除它们，然后返回成功读取的字节数目。如果需要，您可以实现一个类似 readData 的函数来允许非销毁性的读取。实现一个函数来返回当前存储在抽象缓冲区中的字节数目，这样可能会带来好处。清单 6。返回抽象缓冲区中的字节数目

Then the beside question is: what are the stuff at the beginning of the chain.

那么，在链表开头的是些什么东东呢？

Nantong University,Nantong 226019,ChinaAbstract:Comparing with the three basic structures of linked list、tree and graph, the thesis expounds the hypothesis and method of row vector leading linked list data structure to unite the three basic structures which can decrease complication of the algorithm.

本文通过对线性表、树和图三类基本结构的比较分析研究，提出了由行向量引导的链表存储结构来统一三种结构存储的设想和方法，使得某些问题的解决能建立在相对统一的存储结构上，试图降低算法的复杂程度。

Effects : Unlinks the next node of prev_node from the circular list.

作用： 在链表中断开 prev_node 的下一个节点的链接。

Effects : Unlinks the node from the circular list.

作用： 从循环链表断开该节点的链接。

Effects : Unlinks the next node of prev_node from the circular list.

作用： 在循环链表中断开 prev_node 的下一个节点的链接。

Effects : Unlinks the node b, e from the circular list.

作用： 从循环链表断开节点 b， e 的链接。

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。
