近代科学技术发展的一个重要特点是向高精尖前进!在声学领域中,特超声正是这样的产物.它是在近代固体物理、微波和低温等技术基础上发展起来的. 频率在1千兆赫以上的声波称为特超声或微波超声.称为特超声是因它的频率远远地高于一般的超声频率,而微波超声的命名则是由于它的频率是与微波频段相对应的.千兆赫级的特超声早已在1947年获
One of the important features of the development of modern science and technology is to advance to the sophisticated! In the field of acoustics, special ultrasound is such a product.It is based on the modern solid state physics, microwave and low temperature technology based on the development of the frequency of 1000 Sound waves above megahertz are referred to as echosound or microwave ultrasound, which is called echosound because of its frequency far above the general ultrasonic frequency, which is named because its frequency corresponds to the microwave frequency band. Gigahertz ultra-special ultrasound was acquired in 1947
