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。

Each cell was mapped by the center point on the cell of transverse section with extended up and down for four pixel (nine-pixel lengths in total) and two pixels in width, and thereafter line convoluted dot map was obtained. Through Fourier transformation, the frequency distribution of power spectrum pattern from both horizontal and vertical direction was obtained, and the cell diameter in radius and tangential direction was known from the maximum value except 0 in the distribution.

In order to know the effects of mulch-drip irrigation on soil enzyme activities of saline-sodic soil with shallow water table, activities of alkaline phosphatase, urease, and invertase around the dripper, within 30 cm in horizontal direction and 40 cm in vertical direction from the dripper during the reclamation process, were investigated. Changes and distribution of soil enzyme activities, also their relationships with principal soil environment factors were studied.

为了解地下水浅埋区重度盐碱地覆膜滴灌对土壤酶活性的影响，测定了重度盐碱地在滴灌利用过程中距离滴头不同水平位置（0～30 cm）和垂直深度（0～40 cm）的土壤碱性磷酸酶、脲酶和蔗糖酶活性，并对土壤酶活性的变化、空间分布特征及与土壤环境因子之间的相关关系进行分析。

It is the basis for designing balance mass. And, the couple between flexure and torsional vibration is calculated, which is QRSs intrinsic zero drift, and is also main considerations of determining scale factor.(3) There is a difference for equivalent elastic compliance constant of quartz crystal between the X-direction and the Z-direction. It is related directly to each parameter of QRS.

2对由机械耦合产生的零漂作了系统的定量描述，指出质量不平衡等因素产生的零漂可以由加质量和去质量来消除，这是我们设计平衡质量的依据；同时，计算了弯曲振动和扭转振动之间的耦合，指出它是QRS的固有零漂，也是确定QRS标度因子时所必须考虑的主要因素之一。

The exchange of the electrovalence of the cupric ion has been testified by XPS-ESCA.Graphite and chloride in the stage structure,seem to be the conductor and insulator,which form the "sandwich" structure.This special structure produced a weak chemical bond belt and provided the carrier space in the perpendicular direction to the c-axis.These factors in and vertical to the direction of c-axis together increased the electrical properties.
