What differ from that of the researchers in the past is the consideration of the direction of Hopf bifurcation with Dirichlet boundary condition , that is, the conditions when the Hopf bifurcation periodic solutions are orbitally asymptotically stable with asymptotic phase.Our basic idea come from the results given by Tang[30]. We adopt the method used by Hassard in the Hopf bifurcation theorem in [24], which is to judge the existence and the direction of Hopf bifurcation, and the stability of the Hopf bifurcation periodic solutions.

与以前的研究者不同的是，本文不仅讨论了在Dirichlet边界条件下系统的Hopf分支在以扩散系数为分支参数的情况下的存在性和分支周期解的空间非齐次性，而且更多的关注了系统在Dirichlet边界条件下Hopf分支解的稳定性及Hopf分支的方向，也即系统定态解在何种条件下，当分支参数如何变化时产生Hopf分支且分支周期解是带渐近位相轨道渐近稳定的。

Analytic branch amount and branch angle are right produce can influence discovery: Mi Qian is planted increase of number of branch of? of You of that a pavilion or house on a terrace of joyous ǖ of Сざ sew, produce can reduce somewhat, think branch well should not seek overmuch branch amount, with 2~3 branch is advisable; branch angle increases, the yield of much branch well also can increase, but addition extent decrescent.

分析分支数目和分支角度对产能的影响发现：在总分支长度一定的情况下，分支数目增多，产能略有降低，认为分支井不应追求过多的分支数目，以2~3个分支为宜；分支角度增大，多分支井的产能也增大，但增加的幅度变小。

Therefore, based on numerical calculation of a multibranch well's productivity, the influences of the branch angle, branch interspaces and branch length on the gas yield are investigated. The results show that a.
