To improve the accuracy of node trust evaluation in a distributed network, a trust model based on the experience of individuals is proposed, which establishes a new trust assessment system by introducing the experience factor and the comparative experience factor. the new evaluation system considers the differences between individuals and interactive histories between nodes, which solves the problem that nodes have inaccurate assessments due to the asymmetry of nodes to a certain extent. the algorithm analysis indicates that the new model uses different deviating values of tolerance evaluation for different individuals and uses different updating values embodying node individuation when updating feedback credibility of individuals, which evaluates the trust value more reasonably and more accurately. in addition, the proposed algorithm can be used in various trust models and has a good scalability
為了提高分散式網路中各節點信任評價的準確度,提出了一種基於個體經驗的信任模型.該模型通過引入經驗因子和相對經驗因子的方法,建立了新的信任評價體系.這種新的信任評價體系考慮了個體節點的差異問題,在計算節點的信任值時考慮了節點間的交互歷史,這在一定程度上解決了由於節點的非對稱性而導致的信任評價不準確的問題.演算法分析表明:新模型能夠針對不同的個體節點,採用不同的最大容忍評價偏差,並且對個體節點的反饋可信度進行更新時,採用不同的更新值,體現了節點的個性化特徵,使信任評價更加準確合理.此外,所提出的新演算法能夠運用到多種信任模型中,具有很好的可擴展性The questions the researcher concerned are which system will be chosen and how to obtain the good lithium ionic conductor materials, which is the basic departure of the paper. the addition of second phase in composite can change the interface structure and the conduction mechanism, improve the matrix conductivity and other function such as the sintering, crisping and so on, so the research of composites are an interesting field of the ionic conductors. the synthesis of lithium ionic conductor is often by solid state reaction, but this method needs high temperature and leads to the volatility of lithium which not only causes the drift of the compounds but gets the no well - distributed materials
研究者所關注的問題是選擇新的體系進行研究,以期得到性能更好的鋰離子導體材料,這也正是本論文的基本出發點;復合離子導體中第二相的加入改善了基質的界面結構和導電機制,不僅可以提高基質材料的電導率,還可以在一定程度上改善材料的其它性能,如燒結性能、脆性和機械強度等。因此復合材料的研究是離子導體一個有廣闊前景的發展方向;合成鋰離子導體,特別是成分復雜的體系以傳統的固相合成法為主,但這種方法需要較高的溫度,容易引起鋰的揮發,從而造成產物組成的偏移,而且不易得到顯微結構均勻的材料。Among the adaptive beam - forming algorithms, the least mean square algorithm is widely used because it has a simple configuration and it is apt to come true and have nice convergence. on the other hand, it has a disadvantage that it converges slowly and there is a conflict between the fixed step and the convergence pace or the error in stabilization. so people have developed many improved least mean square algorithms which generally start from convergence, stabilization, misadjustment, and robustness and come to a formula about variational step in the end
在自適應波束形成演算法中,最小均方( lms )演算法因結構簡單,易於實現,能穩定收斂而得到廣泛應用,但它也存在收斂速度受限的缺點:固定步長因子無法解決收斂速度和穩態誤差之間的矛盾。因此,人們提出了各種改進的最小均法演算法來解決這一問題。改進的最小均方演算法通常從如何改進收斂速度、穩態誤差、失調量和魯棒性等指標上出發,最後在新演算法最終表達式中的步長公式上變化。Abstract : the causes for low efficiency of the heater in no. 2 crude unit of jpc refinery are described and analyzed including water leaking of steam soot blower, dew point corrosion caused by steam, soot deposits in convection chamber owning to poor soot blowing, high flue gas temperature, no heat recovery of flue gas, and poor performance of insulation lining, etc. by using sonic soot removing system, flue gas recovery system, spray coating of fiber and rock wool, as well as adjustment of flow scheme accordingly in the technical revamping. the dew point corrosion is completely eliminated, the insulation performance is improved, the heat loss is reduced by 1. 25 %, the flue gas temperature is reduced to about 170, and the heater efficiency is increased from 83 % to more than 90 %

Cmcpe具有了一般碳糊電極的特點,同時又因為修飾了特定物質,使cmcpe具有了特定的功能,越來越受到電分析工作者青睞。而超分子化學是一個新興的跨學科的交叉前沿領域,由於超分子化學解決了一直困擾化學工作者的選擇性問題,因而從其理論提出以來,就得到了巨大的發展。可以預期超分子化學在化學修飾電極方面將有非常廣闊的應用前景,但現在由於將超分子試劑修飾在電極這一環節上存在困難,所以現在超分子試劑在cpe上應用較少,在cmcpe中的應用更少。Thereinto communication with host machine comes downto time ' s checking and synchronization, the corresponding method is combined with valid calling core and makes the delay to the least. we also use the display board with electronical map and settle the matter of orientation. to the problem of historic data, we have resolved the redundance of data and reduced the space of data ' s copying
