1.带电粒子在电磁场中的经典 Hamiltonian 设粒子的质量为,电荷为q,电场强度为E,磁场强度为B,那么直接写出这个粒子的经典运动 方程是 B).(SI制) 现在我们问:什么样的H(F,P)给出的正则运动方程是上面这个方程(P是粒子的“正则动量”)?

This equation accounts for the kinetic data given in Figure 8-15.At very low substrate concentration, when [S] is much less than KM, V [s]Vmax/KMi that is, the rate is directly proportional to the substrate concentration At high substrate concentration, when [SI is much greater than KM, V=Vmax; that is, the rate is maximal, independent of substrate
