matcont的计算信息

matcont给出的计算结果
label = ZH , x = ( 1.005275 0.000000 0.755702 0.889333 8.087400 1.273323 )
(s,theta,E0)=(-1.000000e+000, 7.302754e-002, -1)


label = GH, x = ( 0.142877 0.000000 -0.056995 1.004500 1.211508 11.070389 12.533192 )
l2=-8.007226e-002


label = BT , x = ( 1.704205 0.000000 0.301404 0.227797 3.248850 1.953330 )
(a,b)=(-1.850276e+000, -3.181614e-001)


Limit point cycle (period = 1.783310e+000, parameter = 1.078014e+001)
Normal form coefficient = -2.763830e+000


Period Doubling (period = 2.104968e+000, parameter = 1.129444e+001)
Normal form coefficient = -6.727362e+001


ZH-----Zero Hopf bifurcation
BT-----Bogdanov-Takens bifurcation
GH----Generalized Hopf bifurcation


以上信息中的:
(s,theta,E0)=(-1.000000e+000, 7.302754e-002, -1);
l2=-8.007226e-002;
(a,b)=(-1.850276e+000, -3.181614e-001);
Normal form coefficient = -2.763830e+000
分别代表什么意思?和系统的稳定性有关吗?小于0是否就说明是稳定的?有什么依据吗?
