The formula reflects the macroscopic physical phenomena observed in concrete experiments that the nominal fracture energy of concrete increases with the increase of the specimen size and that the nominal fracture energy converges asymptotically to a constant when the specimen size tends to infinity. 该公式反映了混凝土实验中所观测到的宏观物理现象,即混凝土名义断裂能随着构件尺寸的增大而增大,而且当构件尺寸趋向无穷大时,名义断裂能趋近于常数。
The macroscopic spray characteristics of liquefied petroleum gas ( LPG) and diesel fuel spray were studied by the high-speed photography in a constant volume chamber. 在定容室内,采用高速摄影技术对液态LPG喷雾的宏观特性进行了研究,并与柴油进行了对比。
The simplicity sense of microcosmic constant and macroscopic constant were explained substantive thinking and ultimate thinking respectively, while the complexity sense of microcosmic variable and macroscopic variable were explained energy thinking and bifurcation and chaos thinking respectively. 实体思维和终极性思维分别阐释了微观不变和宏观不变的简单性观念,而能量思维和分岔与混沌思维则分别阐释了微观可变和宏观可变的复杂性观念;
