言语交际中的模糊语言及其语用分析

借助题旨情境，模糊语言在言语交际中十分活跃，语用灵活，可使言语表达更加有效、更加睿智、更加委婉、更加灵活。应结合语境并随语随文来剖析其表象，阐释其语义，体会其言外之意和弦外之乐。     

Bernoulli数模2r和3r的同余式

设{Bn}为Bernoulli数,m、n为自然数,本文证明了同余式(2-22n)B2n≡1-4n ∑mk=1(2n)/(2k)24kB2k (mod 24m 3)与(3-32n)B2n≡2-6n 2∑mk=1(2n)/(2k)32kB2k (mod 32m 1).取m=1,2,得到[5]中宣布的(2-22n)B2n(mod 27)与(3-32n)B2n(mod 35)的简单同余式.

金属在福州地热水中的腐蚀热力学研究──(I)、铜—地热水系统

作者从热力学角度以电位－ｐＨ图探讨金属在福州地热水中的腐蚀趋势．本文报导铜－地热水系统，采用ＢＡＳＩＣ语言编制程序在ＡＰＰＬＥ－Ⅱ微机上计算高温热力学数据，并以ＤＸＹ－８００绘图仪绘制电位－ｐＨ图．同时，测定了铜在福州Ｇｗ２井地热水中的实际腐蚀电位．结果表明：在此地热水中，当温度低于３１８Ｋ，铜表面生成Ｃｕ２Ｏ膜，高于３１８Ｋ，生成ＣｕＯ膜，二者都位于钝化区．

Functional magnetic resonance imaging of amphetamine craving

The aim of this study is to identify the brain activity associated with amphetamine craving for understanding the neurobiology of addiction by watching pictures of happy, sad or amphetamine. Brain activity was measured in 12 amphetamine addicts and 12 healthy subjects by fMRI while the subjects watched pictures designed to elicit happy feelings, sad feelings, or the desire to use amphetamine. The result demonstrated that amphetamine cues led to abnormally high cingulate and low frontal lobe activation in amphetamine addicts, who showed abnormalities in affect-related brain activation.     

An ERP study for the degrees of the difficulty in visual search

The present study mainly probed the relationships between ERP components and the degrees of difficulty in visual search. Three experimental and one controlled conditions were randomly selected. Results showed that the P1, N1, and P2 amplitudes and latencies had no significant differences among the three experimental and one controlled conditions, and the ERP waveforms of low perceptual load of visual search were different from that of high perceptual load. These results might indicate that the latencies and amplitudes of initial P1, N1 and P2 in high and low perceptual load conditions were almost the same. The ERP waveforms of parallel search were very different from that of serial search, and the ERP waveforms of serial search were very similar. The P3 amplitudes increased as the degrees of the difficulty in visual search decreased.
