THE UNIFIED SOLUTION OF THE INCOMMENSURATE PHASE IN FERROELECTRICS

引用

Chinese Physics Letters 1984年第1期1卷 27-30页

作者： GUO Ru yang zhen-qing Department of Physics Nankai UniversityTianjinChina

We derive a unified multi-harmonic modulation solution of the incommensurate phase with a simple model by a method like that used in solving pendulum problems in mechanics. This solution reduces to single-harmonic modulation at the upper end of temperatures, and transforms into kink solution at the lower end of temperatures, The basic wave-vector decreases monotonically with temperature, as was observed in experimentation.

Unsuccessful letter–sound integration in English reading by native Chinese speakers: evidence from an event related potentials study

引用

Science Bulletin 2016年第24期61卷 1855-1864页

作者： zhen yang Cuicui Wang Liping Feng Shifeng Li Sha Tao State Key laboratory of Cognitive Neuroscience and Learning and IDG/Mc Govern Institute for Brain Research Beijing Normal University College of Chinese Language and Culture Beijing Normal University

Integrating letters and sounds are essential for successful reading in alphabetic languages. It remains unclear if native speakers of non-alphabetic languages integrate letters and sounds in reading an alphabetic lan- guage in the same way as native alphabetic readers do. Chinese is a morpho-syllabic system （each character cor- responds to one syllable） and contrasts sharply with alphabetic languages such as English. Several fMRI studies have shown that native Chinese speakers apply their native language system to read English words. By using the cross- modal mismatch negativity （MMN） paradigm, we directly investigated letter-sound integration for reading in English among native Chinese speakers. To investigate the effect of native language background on letter-sound integration in second language reading, a group of native Korean English learners served as a comparison group. We compared MMN responses between an auditory only condition （only vowels presented） and two audiovisual conditions （AV0, vowel presented synchronously with the corresponding letter; AV200, the letter presented 200 ms before the corresponding vowel） for both native Chinese and native Korean speakers. Native Chinese speakers demonstrated significantly attenuated MMN amplitudes in audiovisual conditions compared with the auditory only condition, regardless of their phonological decoding speed. In con- trast, native Korean speakers showed amplified amplitude MMN in AV200 compared with that in the auditory only condition. The results suggest that native language may shape the brain responses of second language learners to reading a second language in the early stages. Native non- alphabetic language speakers may be unable to use visual information to facilitate their phonological processing in the early stage while naT：lye alphabetic language speakers are capable of integrating letter sounds automatically.

Phase Probability Density Function in Two-Mode Fock Space

Chinese Physics Letters 1997年第7期14卷 481-484页

作者： FAN Hong-yi yang zhen-shan Department of Material Science and Engineering University of Science and Technology of ChinaHefei 230026

Based on the newly found representation|η>=exp[-(|η|^(2)/2)+ηa^(■)+η^(*)b^(■)-a^(■)b^(■)]|00>in which the phase operator√(a+b^(■))/(a^(■)+b)corresponding to Shapiro-Wagner phase measurement scheme manifestly exhibits its phase behavior,we construct the phase probability density function in the two-mode Fock space,which provides an alternative approach for analysing the phase properties of optical fields.

作者： DENG Zong-yuan SHAO Xi yang zhen Institute of Signal and Information Processing Nanjing University of Postsand Telecommunications Nanjing 210003 China

Steganalysis can be used to classify an object whether or not it contains hidden information. In this article, is presented, a novel approach to detect the presence of least significant bit（LSB） steganographic messages in the voice secure communication system. A distance measure, which has proven to be sensitive to LSB steganography by analysis of variance （ANOVA）, is denoted to estimate the difference between the host signal and the stego signal. Then an maximum likelihood （ML） decision is combined to form the classifier. Statistical experiments show that the proposed approach has a highly accurate rate and low computational complexity.

High Speed Aircraft Robust Fuzzy Controller Design Based on H_∞Performance

引用

Journal of Electronic Science and Technology 2017年第1期15卷 83-89页

作者： Chun-Ning yang zhen-yang Chai Quan-Jun Liu Hui Ge School of Aeronautics and Astronautics Zhejiang UniversityHangzhou 310027China Science and Technology on Space Physics Laboratory Nanjing 210000China Institute of Spaceflight Control Technology Shanghai 200000China

The dynamics of the high-speed vehicle（HSV） is partially or completely unknown because of various reasons, such as modeling errors, in-flight failure, and external disturbances. In this paper, a global stability robust fuzzy controller is designed to control the flight F-16 with uncertain perturbation. For the desired H_∞ output-feedback controllers, a necessary and sufficient condition of quadratic stability is derived with the well-established results of the Lyapunov stability theory and nonnegative matrix. The controllers not only guarantee the global asymptotically stability of the resultant closed-loop system with external disturbance and parameter perturbation, but also have a desired H∞ performance in a large flight envelop（LFE）.
