经济全球化对口译人才的需求

经济全球化给中国既带来机遇又带来许多挑战，急需高素质口译人才在国际合作与交流中承担重要的桥梁作用，也从多角度对口译人员提出了更高要求，口译人员不仅应具备政治道德修养，个人心理素质，语言文化素质，更要具备专业知识，还要掌握口译技能。而目前我国口译现状严重滞后，为此，口译人才培养要面向经济全球化，推行口译教学改革，最终满足社会对口译人员的迫切需求。

Estimation of Hourly and Daily Global Solar Radiation at Clear Days Using an Approach Based on Modified Version of Gaussian Distribution

The performance of two models,Jam and Baig,based on the modified version of Gaussian distribution function in estimating the daily total of global solar radiation and its distribution through the hours of the day from sunrise to sunset al any clear day is evaluated with our own measured data in the period from June 1992 to May 1993 in Qena Egypt The results show a high relative deviation of calculated values from measured ones,especially for Jain model,in the most hours of the day,except for those near to local noon.This misfit behavior is quite obvious in the early morning and late afternoon A new approach has been proposed in this paper to estimate the daily and hourly global solar radiation This model performs with very high accuracy on the recorded data in our region.The validity of this approach was verified with new measurements in some clear days in June and August 1994.The resultant very low relative deviation of the calculated values of global solar radiation from the measured ones confirms the high performance of the approach proposed in this work
