利用这个关系，本文推广了上、下概率的概念，并用其解释了Guan和Bell提出的广义证据理论，同时还证明了Guan和Bell定义的条件信任函数，实际上是Dempster条件规则的推广。

In this paper, an approach to handling this problem is proposed. Before adopting the Dempsters rule to combine belief functions, the assignments of mass functions are pretreated by the disturbance of ignorance.

提出一种新的冲突证据合成方法，即在Dempster合成之前，基于未知扰动对mass函数进行预处理，并通过预处理来解决标准化问题。

The pretreatment is in favor of the normalization of combination. Compared with other alternatives, the new approach is consistent with Dempsters rule in the form and flexible to combination, especially, it can be theoretically explained by the generalized Bayesian formula.

与其他相关方法相比，这种新方法不仅和Dempster规则形式上一致，合成过程比较灵活，并且可以通过扩展的Bayes公式得到理论上的解释。

Generalizing the concepts of upper and lower probabilities, the paper gives a kind of interpretation for the generalization of evidence theory which was defined by Guan and Bell, and proves that the conditioning belief functions defined by Guan and Bell is,in fact, a generalization of Dempsters rule of condition.

利用这个关系，本文推广了上、下概率的概念，并用其解释了Guan和Bell提出的广义证据理论，同时还证明了Guan和Bell定义的条件信任函数，实际上是Dempster条件规则的推广。

The combination of conflicting evidences has been one of the important issues in Dempster-Shafer theory since the example of Zadeh paradox produced by Dempsters rule of combination was found. There is no solution accepted universally as yet.

自从发现Dempster合成可能导致悖论以来，冲突证据合成一直是Dempster-Shafer理论的重要研究方向之一，迄今尚未有统一的解决方法被广泛接受。

The approach converts linguistic variables and calculates the basic utility assignment value of each focal element. The values are integrated according to Dempsters rule of combination. Alternatives are then ranked by comparing the values of belief function and plausibility function. The last chapter summarizes all the work of this paper, and gives some useful suggestions for future research.

该方法首先首先对多个专家给出的不同语言变量进行转化处理；然后计算各焦元的基本概率分配函数值，最后通过Dempster合成法则对其值进行合成，依据合成后的信度函数值和似真函数值对方案进行排序。

The energies in different scales after the wavelet decomposition respectively are applied to extract feature, and absorptive method based on Dempsters rule is used in feature fusion of multi-source information. The results of the simulations between absorptive method and nearest neighbor method are compared, which show the effectiveness of evidence reasoning used in multi-target recognition.

利用了小波分解尺度细节信号能量特征作为四类目标声信号提取的特征，采用基于D-S的新组合规则吸收法对多传感器信息进行特征融合，并对吸收法及最近邻法两种情况下的识别效果进行了对比，仿真结果表明证据推理为声信号多目标识别提供了一种有效的方法。

In the days of sailing vessels the crew were afraid they would be becalmed on the ocean.

在使用帆船的时代，船员们担心他们会因为无风而无法在海洋上航行。

As long as foreign donors pay the PA's salary bill, few expect a new intifada.
