In addition to the equations of linear impulse and momentum considered in the previous lecture, there is a parallel set of equations that relate the angular impulse and momentum. Angular Momentum We consider a particle of mass, m, with velocity v, moving under the influence of a force F. The angular momentum about point O is defined as the \moment\ of the particle's linear

1.理想气体状态方程式 pV=(m/M)RT =nRT 或Pm=p(Vn)=R 式中p,V,T及n单位分别为Pa,m3,K及mol。Vm=Vn称为气体的摩尔体 积,其单位为m3mol=8.314510jmo.k-1,称为摩尔气体常数 此式适用于理想气体,近似地适用于低压的真实气体
