The use of "speculative fiction" in the sense of expressing dissatisfaction with science fiction was popularized in the 1960s and early 1970s by Judith Merril and other writers and editors, in connection with the New Wave movement.

超过百分之九十的现代推理小说都采用同一种视角：限制性第三人称视角&，这里把&Speculative fiction&翻译作&推理小说有些不同看法。

By using the fuzzy-inferential decision technique of the multi-point sensor information,the final optimal decision value for the temperature outrange possibility is calculated from the multi-point temperature monitoring information.

采用多传感器信息模糊化推理决策技术，对多点温度监测信息按模糊推理决策规则计算出温度超限可能性的总体最优决策量值。

The traditional opinion is that the logic form of retroduction is the form of affirmative consequent of hypothetical inference under ample conditions.

传统观点认为，回溯推理的逻辑形式是充分条件假言推理的肯定后件式。

Retroduction is a model form of inference which is:□q→(pq→◇p. There are two characteristics about this logic fo...

该逻辑表达式有两个主要特征：一是推理前提在形式上保真；二是推理的结论具有或然性

This paper presents a N-R method of acquiring multi-level reasoning production rules automatically based on NN, so as to resolve the bottle neckproblem in building a knowledge - based system-knowledge acquisition. This methodadopts a characteristic NN structure model and corresponding learning algorithm, so thatN -R method can fix the number of hidden nodes dynamically and form new conceptswhich are not defined in the sample set in the course of learning. Having been trained, NNis transforme...

本文为解决知识系统构造过程中的瓶颈问题──知识获取，提出了一种基于神经网络NN的自动获取多级推理产生式规则的N－R方法，该方法采用了特有的NN结构模型和相应的学习算法，使得NN在学习过程中动态确定隐层节点数的同时，也产生了样例集中没有定义的新概念，学习后的NN能用本文提出的转换算法转换成推理网络，最终方便地得到产生式规则集

C . the weak ability of the inference engine. because of the too simple inference methods and the unflexible control strategy.

推理方法简单，控制策略不灵活，导致推理能力弱；容易出现&匹配冲突&，&组合爆炸&及&无穷递归&等问题。

In degraded PSM matching classification, errors modification method of degraded PSM is presented and the matching tensor of every canonical scattering centers is given. In Chapter 4, the theory of wideband millimeter-wave radar target identification is introduced. It is indicated that, for HR radar target identification, description of temoral relations among features and pattern recogntion adaptive to variation of target angles are of key importance. A rule-based pattern recogniton method of sequential reasoning is proposed, which uses a series of rules to describe relations of features variation caused by target angles variation and has the advantages of adaption to unrandom variation and false probability control in classification over traditional statistical pattern recognitiop method. Feature extraction is crucial step in target identification. In range profiles identification application, features are extracted by means of range domain pre-processing algorithm, spacial and amplitude visual computation directly from range profiles and transform algorithm based on range profiles. Visual or transformed features are either sufficiently convinced or necessarily convinced and both of them are effective and robust to range profiles identification.

在第四章，首先对宽带毫米波体制背景下目标识别方法的一些特点进行了阐述并指出，在毫米波雷达目标识别中，特征之间动态关系的描述以及能适应目标姿态角变化的模式识别方法的研究乃是要解决的关键问题；进而提出了一种基于规则库的序贯推理模式识别新方法，在这种方法的研究中，主要包括序贯推理规则库的规则排列与特征选用顺序以及规则库的收敛等问题；这种方法克服了传统的统计模式识别方法特征利用效率不高、难以适应特征值的非随机性变化的缺点，把姿态角变化所引起的特征的变化用一系列规则加以表示，其优点是能适应特征值的非随机性动态变化，并能控制分类过程中的差错概率α；特征抽取是目标识别中的关键步骤，在基于目标距离像的特征抽取方法研究中，提出了距离空间域的预处理算法、距离空间域与幅度域的直观特征抽取方法以及基于目标距离像变换分析的特征抽取方法。
