【正文】 ties of real data to be sure, do not need to microstructure of the material to make any assumptions, so analysis of the results of reasoning with a high degree of reliability, and coherent . This is its unique advantages. Ancient man long ago learned to make fire and use of fire, but then pay attention to explore the hot, cold real phenomenon. However, until the end of the 17th century, people still can not correctly distinguish between temperature and heat of these two basic concepts of nature. Popular at that time, said Heat and Mass Transfer under the rule, people mistakenly believe that the high temperature object is stored as a result of thermal mass number. 1709 ~ Fahrenheit temperature scale in 1714 and 1742 ~ 1745 Celsius temperature to establish the subject to move the temperature with accepted standards. Followed by calorimetry technology developed for Earth observation science and thermal testing means is provided so that thermal embarked on the path of modern experimental science. 1798, Langford was observed drilling with drill barrel, the consumption of mechanical work and the result are warming bit. In 1799, the British David with two resulting in friction between the ice surface melting, which is obviously not from the Heat and Mass said, be explained. 1842, Meyer made the conservation of energy theory, that heat is a form of energy can be transformed into mechanical energy with each other, and the air pressure from the specific heat capacity with constant volume specific heat capacity to calculate the difference between the mechanical equivalent of heat. British physicist Joule heating in the equivalent in 1840 to establish the concept in 1
