| 摘 要： | 针对Goldbeter五维果蝇生理节律模型进行了分析,得出系统平衡点的渐近稳定性条件,同时分析了果蝇的生理节律.在L-D循环光照作用下,当果蝇的生物钟处于渐近稳定条件时,利用摄动理论证明系统可以产生周期振荡,且当果蝇的生物钟具有周期解时,系统在一定条件下可能出现倍周期现象.

| Abstract: | Based on the analysis of Goldbeter's five orders Drosophila circadian model,the asymptotic conditions of equilibrium points were derived.Besides,under the condition of L-D cycle and in asymptotic condition,by using perturbation theory analysis the Drosophila circadian oscillation,the paper obtains circadian oscillation.And based on this circadian oscillation,the phenomenon of period-doubling can ocuur under certain conditions. |

| Keywords: | L-D cycle asymptotic stable circadian oscillation |
