为了测定气体的γ(γ=Cp/CV),可用下列方法:一定量气体,它的初始温度、体积和压强分别为T0,V0和p0.用一根通电铂丝对它加热,设两次加热电流和时间相同,使气体吸收热量保持一样.第一次保持气体体积V0不变,而温度和压强变为T1,p1;第二次保持压强p0不变,
The ratio of heat absorbed by a substance to the temperature change is known as heat capacity. In terms of the actual amount of material being considered, most frequently a mole, it is usually stated as calories per degree (the molecular weight in grams). Specific heat is the heat capacity...
SIGN:此选项个人感觉可加可不加,如果设置AXIS为单个X,Y,Z的方向则此选项设置了也没有什么用,且SIGN默认为T。 &DISTANCE_FUNCTION:&DISTANCE_FUNCTION这个集合变量主要是用于整合两个distance,将其合并为一个distance类型的;集合变量,个人感觉如果在体系中你希望考察多个距离的变化过程,可以采用此CV,从而减少了由于通过...
Both strain rate sensitivity and strain hardening exponent decrease with prestrain. Fracture surfaces of the specimens show that fracture mechanism of all tested specimens is dimple fracture. The more ductile deformation in prestrained CP-Ti after annealing indicates that its ductility is improved by ...
