In the fields of materials science and engineering, measuring temperature has become one of the most fundamental and important issues.
Ultrasound is expected to be an alternative for monitoring the internal temperature and its gradient in materials because of its capability to probe the interior of materials and its high sensitivity to temperature [2-7].

Scientific Feature of the Definition As a scientific abstract of functions of the people, animals (biological creatures) and all man-made machine system, Generally, TM consists of four parts, materials, tools, power and information.
Since the existence of TM is base on materials as defaulted, "Top Machine" (as shown in Fig.2)is formal defined as a triad, namely TM::= (F,P,I).
