十二面体

Heat, a mode of motion developed by such combustion, was constantly and increasingly conveyed from the source of calorification to the liquid contained in the vessel, being radiated through the uneven unpolished dark surface of the metal iron, in part reflected, in part absorbed, in part transmitted, gradually raising the temperature of the water from normal to boiling point, a rise in temperature expressible as the result of an expenditure of 72 thermal units needed to raise 1 pound of water from 50 degrees to 212 degrees Fahrenheit.

燃烧所引起的运动形式之一--热，不断地、加速度地从热源体传导给容器中的液体，由那凹凸不平、未经打磨的黑色铸铁面把热向周围发散出去；一部分反射回来，一部分被吸收，另一部分被传导，使水的温度从常温逐渐升到沸点。这种温度的上升可作为消费结果标志如下：将一磅水从华氏五十度加热到二百十二度，需耗七十二热量单位。

The numbers of clusters made up of 1551 and 1541 bonded pairs representing the non-crystal structure occupy predominate position and the small numbers of clusters made up of 1431, 1661 and 1441 bonded pairs coexist in the non-crystal system at 4×10〓K/s cooling rate, thus there exist a large number of icosahedra clusters in the non-crystal system. The numbers of clusters made up of 1421 bonded pairs corresponding to the fcc-like structure occupy predominate position and the small numbers of clusters made up of 1422 and 1551 bonded pairs coexist in the crystal system during the 4×10〓K/s cooling process, thus the system can form the regular fcc-like structure.
