TBS分选机在洗煤厂处理粗煤泥中的试验研究

The Impact of Intercultural Sensitivity on Ethnocentrism and Intercultural Communication Apprehension

针对螺旋分选机分选粗煤泥效果不佳,决定采用TBS分选机进行粗煤泥分选试验,试验结果表明,TBS分选机相比于螺旋分选机分选粗煤泥所得精煤灰分平均降低了2.35%,尾煤灰分提高了1.26%,精煤产率提高了1.5%~2%。TBS分选机的应用对于提高精煤质量、产率和选煤厂经济效益具有显著的效果。

With questionnaires, this study explores the impact of intercultural sensitivity on ethnocentrism and intercultural communication apprehension of Chinese college students. The results show that （ 1 ） among the five dimensions of intercultural sensitivity,participants get the highest score at respect for cultural differences, followed by interaction engagement, interaction enjoyment and interaction attentiveness in sequence, and the lowest score at in- teraction confidence; （2） there are significant negative correlations between intercultural sensitivity and both ethnocentrism and intercultural communication apprehension;（3） eth- nocentrism can be best predicted by respect for cultural differences, and intercultural com- munication apprehension can be best predicted by interaction enjoyment.
