Currently,CO_(2) conversion and utilization have become a key to mitigate the global *** this study,a novel separate-type autothermal dry reforming of methane(S-ATDRM)system is proposed and simulated,in which the methane dry reforming combined with methane partial oxidation is performed in a circulating fluidized bed with exergy recuperation to eliminate the negative effect of the products of CH_(4) partial oxidation on the DRM reaction and further improve the CO_(2) conversion *** results demonstrate that this S-ATDRM system can achieve an exergy efficiency of 84.7%,and about 1055.7 kW of exergy can be recuperated from the process for crude syngas cooling and reapplied for pre-heating of feedstocks of CO_(2),O2 and CH_(4).It is found that the largest exergy destruction in this system occurs in the partial oxidation reactor,which occupies ca.45.6%of the whole exergy *** with the conventional ATDRM system,although the exergy of S-ATDRM system is decreased by approximately 0.3%,the CO_(2) conversion is substantially increased by about 11.3%.

A transport bed flash calcination(TBFC)process applied to magnesite is systematically investigated through process simulation to optimize the energy-saving *** high-temperature calciner flue gas is used to preheat the fed magnesite,while the sensible heat with the caustic calcined magnesia(CCM)product is cooled by air sent to the ***-decomposition of magnesite during preheating is considered on basis of the kinetics measured using a micro fluidized bed reaction analyzer that allows the minimized effect of external diffusion on *** staged fuel gas supply the TBFC process allows the equivalence ratios around 1.2 for *** preferred arrangement of stages for magnesite preheating and CCM cooling are respectively 4 and 2,leading to the energy consumption of 4100 kJ/kg-CCM and the energy efficiency of 66.8%,which is almost doubly higher than the 33.9%of the conventional reverberatory furnaces(RF).The pre-decomposition occurs mainly in the 1st-stage preheater,and the maximal conversion is about 13%.Varying the stages of preheating appears more influential on the energy saving than varying the cooling stages,while residence time above 1 s in the preheaters has limited effect.

非英语母语国家的英语语音教学中，越来越多引入了英语母语国家的自然拼读教学法。然而，缺乏先前音-义连接经验的非英语母语者能否从这种形-音对应训练中同等获益呢?为了检验非英语母语者中音-义连接经验对拼读教学法效果的影响，以120名四年级小学生为被试，采用单因素三水平(前置音-义连接训练组作为实验组，前置首音辨别训练组作为积极对照组，无前置训练组作为消极对照组)被试间实验设计，考查了拼读法训练效果。结果发现，在前置训练中建立起单词音-义连接的儿童从随后的拼读法训练中受益更多，表现出更强的单词拼读能力，并且在新词材料中表现出了近迁移效应。该结果提示在汉语母语者中引进自然拼读教学法的局限性以及解决思路。
