On the base of researching the theory of the scheme and analyzing the signal feature, it is obtained that the existence manners and character of distance information in the differential frequency signal. at the same time, a new conclusion is gained that the technology of frequency agility can decrease the constant error of system. it is also to say that frequency agility and frequency modulation fixed - distance fuze has the similar feature to random period frequency modulation fixed - distance fuze. according to the theory of address coding in the hopping - frequency communication, the paper presents the principle of selecting the frequency agility sequence which fit to the radio fuze and constructs the frequency agility sequence family based on the rs codes
在深入研究方案原理和分析信號特徵的基礎上，獲得了該體制引信差頻信號中，距離信息的存在形式和特點，得出了頻率捷變技術的引入降低了系統定距固定誤差這一新的結論，即頻率捷變調頻定距引信在定距性能上具有類似隨機周期調頻定距的特徵。本文引入跳頻通信地址編碼理論，結合無線電引信的具體特徵，提出了適用於無線電引信的頻率捷變序列的選擇原則，並構造了基於rs碼的寬間隔頻率捷變序列族。 -
The research paper is based on the the latest softwares of the managing inventory, its research subject is about simulating the most appropriate inventory quantity and ordering quantity by statisticing the probability of the random require quantity. its purpose is to provide the relied basement for determining the most appropriate inventory quantity and ordering quantity, the deterring policy quality will be raised, so the damage caused by unfit inventory quantity and the benefit of the entrerpreneur will be raised. the research method is by building the inventory management information system, the system includes automated management of parts entering and going out the datasbase. requesting the records of parts entering and going out the datasbase and displaying the sygonal when the inventory quantity is short out. computer calculating the fix period remaining, requesting remaining at any time and displaying if goods need ordering, all the partsof certain a product going out of basement and at the same time checking if the storaging quantity is enough. then simulating the most appropriate inventory quantity and ordering quantity simulating method is as follows : statisticing the random required quantity. calculating the probability, standing for the values with data range producing random data by function accordingly calculating the random required quantity. thenext step is simulating all the projects after pressing in the simulating conditions. finally selecting the best
本文通過分析國內外關于庫存管理軟體的發展情況，提出在線統計貨物出庫情況的基礎上利用模擬方法確定最優存儲方案，其目的是為制定合理的貨物安全庫存量和訂貨量提供可靠的依據，提高企業管理人員的決策質量，從而減小資金的佔用和缺貨損失，提高企業的經濟效益。通過研製庫存管理信息系統使庫存信息管理自動化，也就是實現貨物入出庫管理計算機管理、自動查詢貨物入出庫情況並在缺貨時給予提示、使用計算機貨物余額定期結算、貨物余額實時查詢並顯示是否需要訂貨、裝配出庫管理使得只要輸入需要裝配產品代號和數量，組成它的所有零件就會自動檢庫和出庫。然後對安全庫存量和訂貨量進行模擬，模擬方法是首先自動統計貨物在過去某一段時間內的需求量，計算出概率，用隨機數的范圍表示其概率數值的大小，利用隨機函數產生隨機數、從而間接的產生隨機需求量，給定模擬天數和其他模擬條件模擬各種方案，從眾多的存儲方案中找出最優存儲方案。 -
Time domain noise is simulated by the mathematical pseudo uniform or normal random variable and coupled to deterministic signals such as rectangular ( rect ), triangular ( tria ), unit step exponential ( uexp ), even exponential ( eexp ), or gaussian ( gauss ) pulse voltages in finite number of time samples in finite time period

Under the influences of random variabilities, during both construction period and operation period, the temperature field within a gravity dam body could be regarded as a random one. in this paper, stochastic finite element methods are suggested to deal with the random temperature field. by use of the suggested methods, the influences of random environmental and random hydration heat of concrete and the initial temperature of concrete as well as the thermal parameters of both concrete and rock foundation are all taken into account. according to a scheduled time table of construction, random temperature fields of a typical concrete gravity dam within both the construction period and the operation period are calculated by emulation the layer constructing of the dam. some useful conclusions are obtained from the computational results
由於施工期和運行期各種隨機因素的影響，使重力壩溫度場成為隨機.本文綜合考慮了環境溫度（包括氣溫和庫水溫度） 、混凝土絕熱溫升、入倉溫度以及混凝土和基巖的熱學參數隨機性的影響，基於隨機有限元法，給出了重力壩隨機溫度場的計算方法，對一典型重力壩按給定的施工進度模擬分層澆築施工過程，對施工期及運行期前期的隨機溫度場進行了計算，並得出了一些有益的結論 -
