日本超声电机的产业化,应用和发展

叙述了日本超声电机的产业化现状、应用研究和新型超声电机的发展情况。大量实例充分证明：日本超声电机技术处于世界的前列。在这个技术领域，我国与日本尚有很大的差距。文中分析了产生这个差距的原因，并提出了迅速地缩小这个差距的有效途径。最后总结出我国必须努力跟上世界超声电机技术的发展步伐，并且要在短期内达到与日本超声电机技术相同的水平的结论。

Industrialization,Applications and Development of Ultrasonic Motors in Japan

From October 4 to October 20,1998,the authors paid a visit to six universities and four compaines in Japan for an invesigation concerning the progress of ultrasonic motors in the country.This paper describes in detail their present status of industrialization and applied researches of the motor,and its development of new types.The investigation demonstrates that Japan stands in the forefront of ultraoanic moter technology in the world,and there is a great gap between China and Japan in this field.After analyzing the causes of the existence of the gap,an effective way to narrow the gap is suggested.Finally,the paper comes to the condusion that China should do the best to keep pace with the development of the technology in the world,and attain the same technical level as that of Japan in a short time.
