| 1 | Spatial distribution of ion polytropic index joint-modulated by temperature anisotropy and MHD disturbances in the southern high latitude magnetosheath显示文摘Using the Cluster data from 2001 to 2010, we studied spatial distribution of effective ion polytropic index in the southern high latitude magnetosheath, and joint-modulation of ion polytropic index by temperature anisotropy and MHD disturbances. The magnetosheath ions generally experience various polytropic processes with different polytropic index. The median polytropic indexes of magnetosheath ions in the GSE X-Y plane decrease toward the bow shock. Near the magnetopause, the median polytropic indexes are basically between isothermal and adiabatic except in the duskside flank close to the terminator. The analysis of correlation coefficient of perturbed ion number density with parallel magnetic field CC_δnδB_‖ and ion temperature anisotropy parameter A_T, indicates that the dominant MHD disturbance near magnetopause is slow mode with larger ion temperature anisotropy, and there are various modes of MHD disturbances with insignificant ion temperature anisotropy near the bow shock.The polytropic index modulated by slow mode disturbances is generally larger than that modulated by fast mode disturbances, and the larger ion temperature anisotropy, the larger polytropic index. The median polytropic indexes modulated jointly by slow mode disturbances and the strong ion temperature anisotropy can be larger than 1.0, while those modulated by fast mode disturbances and weak temperature anisotropy can be even possibly close to zero. Moreover, because of pronounced dusk-favored asymmetry of ion temperature anisotropy, the median polytropic index in the dawnside flank of the magnetosheath near the terminator is smaller than that in the duskside flank of the magnetosheath. The good correspondence between the distributions of median polytropic indexes and ion temperature anisotropy and MHD disturbances indicates that the ion temperature anisotropy and MHD disturbances determine the distribution of the polytropic index in the magnetosheath. | PANG XueXia CAO JinBin DENG ZeChao JIA PengYing | 2018 | Science China(Technological Sciences)2018，61，3： | 2 |

| 8 | The Functions of Discourse Markers in Chinese-English Consecutive Interpreting显示文摘The term “discourse markers”(DMs in short) was raised in the 1970s and 1980s. Fraser, a linguist, believes DMs have no truth-conditional meaning which means DMs do not change the prepositional meaning of the sentence. He classifies DMs into three categories: discourse topic markers, discourse activity markers, and message relationship markers. It can be concluded that in conference interpreting, DMs explicit internal structures in three aspects: parallel relation, contractive relation, and elaborative relation based on the analysis of DMs in rendition of Premier Li Keqiang’s press conference from 2014 to 2017. | ZHAO Zechao LI Ziang DENG Jianhua | 2019 | Sino-US English Teaching2019，16，2： | 0 |
