uld be extracted from some lasers. Chemists, physicists, and engineers quickly recognized that such pulses would allow direct temporal studies of extremely rapid phenomena requiring, however, development of revolutionary ultrafast optical and electronic devices. For basic research the development ofFLIC 发表于 2025-3-30 21:57:10

bio-acoustics. In the last 35 years a completely new branch of bio acoustics, involving ultrasounds, has been made possible by technical developments that now allow these inaudible sounds to be detected and studied. This subject has a personal fascination for the authors, perhaps because of the noDecibel 发表于 2025-3-31 08:43:06

This instrument allowed the neurosurgeon to selectively remove tumor tissue with decreased blood loss and tissue trauma. The ability now of ultrasonic equip令人发腻 发表于 2025-3-31 20:58:32
Ulrich Heyderal wave is composed of oscillations of discrete particles of material. The motion carried out by a small mass attached to a spring as shown in Fig. 1.1 if pulled down once and released, is called an oscillation. Left to itself, the mass oscillates about the equilibrium position. The nature of this o起草 发表于 2025-4-1 01:42:52
