廠址在本市東河河村東南部，北靠大塘公路，東鄰小南頭化工廠，距變電站約三公里，地下水源豐富，交通運輸方便。The directional routing protocol ds _ dsr put forward by the author is the improvement of the current protocol dsr, complete routine discovery and maintenance by directional neighbor nodes routing table, source routing and directional steering. the research discovers the application of the directional antenna, compare the omnidirectional antenna can increases the networks " total throughput, obviously reduces the co _ channel interference ( cci ), multiple access interference ( mai ), enlarges the nodes " signal and interference to noise ratio ( sinr ), and because of the high gain of directional antenna can realize the communication with farther distance and less jump, end to end delay can decrease deeply, simultaneously, security of networks can be improved partially, the node energy also can be saved easily by power control
本文提出的定向路由協議ds _ dsr是基於對現有協議dsr的改進下實現的，通過定向鄰節點路由表、定向源路由和定向搜索來完成路由發現與維護。研究發現，定向天線的應用，相比全向天線可明顯提高網路的總的吞吐量，減少通道干擾、多址干擾，提高信干噪比，且由於定向天線的高增益可實現較遠距離、較少跳數的通信，減少了路由發現時間，這樣大大減小了傳輸時延，網路的整體性能得到了不同程度的提高，同時部分地解決安全問題，通過功率控制還可較容易的實現節能的目的。The fengtu charitable granary is a research object to the thesis, first, set out from the traditional agriculture culture, and set a background with the the history of granary system granary construct, combinatively based on the economy and political of weibei in in the end of qing dynasty, analyzed the fengtu charitable granary history of the origin and development and its military intention which showed in the origin. lt combinatted the nature geography general situation of the east of guanzhong and the history of the ancient city of chaoyi, discussed the double significances of the store for grain and military in the choose the site of the fengtu charitable granary ; at the same time analysised and compared with the other granary constructs
在光緒末年到宣統年間，大部分義倉已經消失，而豐圖義倉仍然完整地保存著，一定有其歷史原因與存在價值。本文能在這方面起到補充和拾遺的作用。本文首先從傳統農耕文化出發，以古代倉廩制度和倉廩建築的歷史為背景，結合清末渭北政治經濟，分析了豐圖義倉歷史沿革及其建造起源中所體現的軍事意圖；結合關中東部的自然地理概況和朝邑古城的歷史，論述了豐圖義倉選址中儲糧功能和軍事性質的雙重意義；同時與其它倉廩建築進行了分析和比較。Socket function mainly realizes setting up and initializing service unit socket, initializing service unit and service unit serial and so on. bind funcion primarily binds local address and port for the socket. listen function is to evaluate the max length of server ’ s listening queue. connect function and accept function set aside rate ahead, infrom user ’ s request of establishing virtual circuit to suna, cooperate with suna to establish the connection between client and server, return the result. we make use of three handshake with data protocol and virtual circuit mode, in this way, when we translate data, we can look up communication course according to virtual circuit number, at the same time, there aren ’ t source ip address and port, end ip address and port in the head of data package, the speed of translating data advances in a certain extent. send function and recv function is to send data collaborating with suna, and copy data from the receiving queue of socket to user ’ s buffer. close function cooperate
Socket （ ）函數實現創建、初始化服務元套接字，初始化服務元及服務元序列等。 bind （ ）函數為套接字綁定本地地址和埠號。 connect （ ）和accept （ ）函數主要是根據用戶要求預留帶寬，將用戶的建立虛電路請求轉達給服務元網路體系，協作服務元網路體系採用捎帶數據的三次握手協議建立虛電路，並告訴用戶處理結果，一方面，捎帶數據的三次握手協議在一定程度上可提高數據傳輸速度;另一方面，採用虛電路方式，使得數據通信可直接根據虛電路號查找相應的通信進程，而且數據包的包頭中省去了源ip地址、埠號和目的ip地址、埠號，提高了數據傳輸速率。In order to decrease the influence of the interference sources during the test and acquire more reliable and more accurate data, this paper has made a comprehensive investigation on the process of performance measurement based on hardware performance monitoring, including main work as follow : ( 1 ) we have investigated the function and bottom implement of the performance monitoring hardware, and deeply studied on the ia - 64 processors with more advanced mechanism of hardware performance monitoring than others, including program counter sampling 、 period statistics 、 invalidated event address sampling and event restriction
