摘要：A new approach is proposed which can satisfy the range ambiguity requirement while keep the antenna width not to be enlarged and get the high quality image also. Here the chirp slope of the transmitted linear frequency modulated pulses is reversed alternately. Therefore, during the range compression significant portion of the ambiguous return which is due to the mismatching with the signal reference function is suppressed. The suggested method provides significant improvement in range ambiguity ratio and can be utilized in attaining wider swath.

摘要：ambiguity is a unique linguistic feature and is caused by many factors. This paper first introduces the definitions of ambiguity and then mainly illustrates ambiguity in our daily language usage in both English and Chinese from phonetic level and syntactic level. People can learn the relationships among those levels and grasp the rule of learning language. Thus, people can realize the complexity and importance of using language and know that it is not easy to express ideas accurately.

摘要：Distinguishing the difficulty degree of top coal caving was a precondition of the popularization and application of the roadway sub-level caving in steep seam. Because of complexity and uncertainty of the coal seam, the expression of influence factors was diffi-culty with exact data. According to the fuzzy and uncertainty of influence factors, triangular fuzzy membership functions were adopted to carry out the factors ambiguity, of which the factors not only have the consistency of semantic meaning, but also dissolve sufficiently expert knowledge. Based on the properties and structures of fasART fuzzy neural net-works of fuzzy logic system and practical needs, a simplified fasART model was put for-ward, stability and reliability of the network were improved, the deficiency of learning sam-ples and uncertainty of the factors were better treated. The method is of effective and practical value was identified by experiments.

摘要：俯冲前斜SAR(Synthetic Aperture Radar,SAR)具有各方向分辨特性非均匀的特点,传统的合成孔径雷达分辨率描述方法具有一定的局限性,不适用于俯冲前斜SAR的分辨率分析.为了完备地描述前斜SAR系统的分辨率特性,提出了一种基于分辨椭圆的前斜SAR分辨率分析方法,采用广义模糊函数推导了前斜SAR斜平面和地平面分辨椭圆的表达式.仿真结果表明:该方法可以适应SAR系统不同的几何构型和系统参数条件,为前斜SAR系统的参数设计和几何构型配置提供了理论依据.

摘要：Relative clauses(RCs)processing has been a hot issue in *** from head-initial languages have found that SRCs were easier to comprehend than ORCs,and many different models were constructed to account for SRCs *** are head-final languages and the head noun phrases are behind the *** a great difference in syntactic structure made Chinese to be the optimum material to test the models mentioned *** the paper,two experiments were carried out using eye-movement tracking methods to explore the difficulty with RCs processing in mandarin,and results showed that:when the two noun phrases were both from animate category,SRCs were more difficult than ORCs,but when the noun phrases in the internal-relative-clause were inanimate and the noun phrases in the matrix were animate,the difficulties with SRCs were greatly *** on these findings,we hold that the linear syntactic distance between the gap and the filler was not the key reason to the difficulty with *** the contrary,the ambiguity in argument construction may be the most important.

摘要：In this paper, we theoretically and numerically study a combined monopole–dipole measurement mode to show its capability to overcome the issues encountered in conventional single-well imaging, i.e., the low signal-to-noise ratio of the reflections and azimuth ambiguity. First, the azimuth ambiguity, which exists extensively in conventional single-well imaging, is solved with an improved imaging procedure using combined monopole–dipole logging data in addition to conventional logging data. Furthermore, we demonstrate that the direct waves propagating along the boreholes with strong energy, can be effectively eliminated with the proposed combined monopole–dipole measurement mode. The reflections are therefore predominant in the combined monopole–dipole data even before the signals are filtered; thus, the reflections' arrival times in each receiver are identified, which may help minimize the difficulties in filtering conventional logging data. The optimized processing flow of the combined measurement mode logging image is given in this paper. The proposed combined monopole–dipole measurement mode may improve the accuracy of single-well imaging.

摘要：King＇s narratives exemplify the themes of the uncanny, of masking and unmasking, of the corporeal otherisation and of the questioning of identity. This paper is an invitation to go beyond what may commonly be thought of as a uniform looking-glass so as to discover King＇s particular treatment of the body. Far from shying away from sexuality, the American writer depicts it in an ambivalent or disguised manner （Thinner, Mr. Mercedes, Christine, Misery, Cycle of the Werewolf）. If the female body is mainly connected with the taboos of rape and incest （Gerald＇s Game, Dolores Claiborne, Bag of Bones, Under the Dome）, or with ungenderisation （The Tommynockers, Rose Madder）, the notion of monstrosisation can nevertheless be applied to both male and female bodies （The Shining, Desperation, ＂The Raft,＂ ＂Survivor Type＂）. Oscillating between hypermonstration and avoidance, King pulls the strings of the fragmentation, even of the silencing of the body. The fissure impregnating the characters＇ identity and bodies is enlightened by the shattering of the very connection between signifiers and signified, inserting the reader into a state of non-knowledge： a mesmerising dance of disembodied bodies within disembodied texts.

摘要：复义(ambiguity)是指语言中对一个词语或一种结构有两种或多种解释。在广告文体中,复义是一种常见而有力的表现手段。广告商们常常有意识地利用复义这一手段,用简洁的语言表达丰富的思想内涵,以增强广告的特殊效果。本文试从复义在广告英语中的形式和广告功效这两个方面进行如下初探。

摘要：＂Indeterminacy（不确定性）＂是美国当代文学批评家依哈布·哈桑（Ihab Hassan）对后现代主义基本特征的概括性描述,它揭示了后现代主义审美特征的精神品格。这一复杂的现象具有多重的所指：含混（ambiguity）、不连续性（Discontinuity）、异端（Heterodoxy）、多元性（Pluralism）、随意性（Randomness）、叛逆（Revolt）、变态（Perversion）、变形（Deformation）。延伸在艺术创作领域,后现代美学或艺术敏锐地承袭了这种游移的特性。

摘要：英国语言学家露丝·肯普森(Ruth M·Kempson)在她的《语义学理论》中对自然语言的含糊与歧义作过详细的论述.她指出,含糊(Vagueness)与歧义(ambiguity)是语义学中常见的现象,它们是两个不同的语言学范畴.她归纳了各种不同的含糊现象,并把它们分为四类.另外,她还设计了一种叫“to do so too”的歧义句检验法.试图区别歧义句与含糊句.然而,在她的分类中,我们可以看出她对含糊的基本定义是不严密的,因而,她用来区分歧义与含糊的歧义检验法也就不可能凑效了.肯普森认为,凡可容纳多种不具体解释的语句是含糊语句,而可容纳两种或更多的具体解释的语句是歧义语句.这种定义本身是可以接受的,然而,她对这一定义的论证过程是不严密的,甚至是错误的.
