2. An Opening Address (a Model) Образец вступительной речи председателя на научной встрече

Chairman: Distinguished guests, ladies and gentlemen, clear colleagues! It is a great pleasure for me as Chairman of the Organizing Committee to welcome you to the International Symposium on Semiconductor Device Research sponsored by the Division of Chemical Physics of the American Physical Society. I would like to give a special welcome to the President of the American Physical Society, Professor Kenneth Johnson who has found the time to attend our meeting. I express our warmest welcome to the Assistant Director of the Massachusetts Institute of Technology, Professor Charles Stucky. I am sure you will join me in extending a particular welcome to our colleagues from other countries. We are pleased that so many outstanding researchers from all over the world have come to attend this Symposium. We would like to convey our best wishes to all the participants and guests. Two years have passed since our last meeting in Germany. It is a short time, but it has fumed out to be very fruitful There has been remarkable progress in our understanding of the device operation and some underlying phenomena. The most notable achievement is die discovery of room temperature superconductivity. It has brought about improvement in structure technology and in designing new devices and materials. However, our knowledge of the mechanism of superconductivity still remains incomplete. Our main goal in holding this Symposium is to discuss various aspects of new materials for semi- and superconductor structures. The range of subjects to be considered is quite large. But it is our hope that the Symposium will show the current state of things in this rapidly developing area and stimulate new ideas. Because the meeting has brought together scientists with different points of view, with different backgrounds of training and experience, we; expect stimulating discussions of theoretical and experimental problems. I wish you success. Thank you.
