Zhalong National Nature Reserve （Zhalong） is an important stopover for migratory birds. In recent decades, Zhalong has become the focus of researchers and public discussion in relation to irrigation. We studied relationships between birds and habitats at different water levels to guide development of more effective habitat management measures. We used line transects to survey bird numbers and distribution during April-May from 2005-2009 at Zhalong, and used cluster analysis and Chi-Square tests to analyze data. We recorded 139 bird species of 39 families and 13 orders during spring migration, including Anseriformes, Charadriiformes, Ciconiiformes, Columbiformes, Coraciiformes, Cucu- liformes, Falconiformes, Galliformes, Gruiformes, Passeriformes, Pici- formes, Podicipediformes, Strigiformes. Dominant vegetation and geo- graphic region were the main influence factors of avian distribution. Different ecological groups preferred different water levels （p〈0.01） and different habitat types （p〈0.01）. Grallatores, Natatores and Passeres were the main ecological groups in different wetland habitats, and reed marsh and lake are the main habitats for management. Grallatores preferred reed marsh and lake with water levels 〉30 cm and 5-15 cm. Natatores preferred lakes with deep water （〉30 cm）. Passeres preferred open forest and reed marsh with no surface water. Different avian ecological groups occupied specific habitats depending on water level and we recorded some overlaps in bird distribution.

为化解产品变型设计过程中参数关联结构关系复杂的问题,将产品结构层次用广义模块进行表示,以减少产品结构层次,缩短参数传递链。运用有向图理论,提出了广义模块参数关联结构有向图的概念,用有向图顶点表示广义模块、子模块和零件,将参数关联驱动关系用有向边表示,得到广义模块参数关联有向图的性质。通过产品广义模块化结构层次关系,将广义模块参数关联结构有向图划分为多个子图,并对子图中顶点之间的横向有向边进行分解,建立了一种规范的参数关联结构关系,给出了其分解算法和参数关联的数学描述,为变型设计参数关联分析提供了理论依据。最后,以皮带输送机为例说明了该方法的有效性。

AIM: To investigate and determine the mechanism and signal pathway of tetradecanoylphorbol-1, 3-acetate (TPA) in degradation of RXRα.METHODS: Gastric cancer cell line, BGC-823 was used in the experiments. The expression level of R XRα protein was detected by Western blot. Nuclear and cytoplasmic protein fractions were prepared through lysis of cell and *** and translocation of RXRα were observed under laser-scanning confocal microscope through labeling specific anti-RXRα antibody and corresponding immunofiuorescent antibody as secondary antibody. Different inhibitors were used as ***: In BGC-823 cells, RXRα was expressed in the nucleus. When cells were treated with TPA, expression of RXRα was repressed in a time-dependent and TPAconcentration-dependent manner. Meanwhile, translocation of RXR from the nucleus to the cytoplasm occurred, also in a time-dependent manner. When cells were pre-incubated with proteasome inhibitor MG132 for 3 hrs, followed by TPA for another 12 hrs, TPA-induced RXRα degradation was inhibited. Further observation of RXRα translocation in the presence of MG132 showed that MG-132 could block TPAinduced RXRα redistribution. Conversely, when RXRαtranslocation was inhibited by LMB, an inhibitor for blocking protein export from the nucleus, TPA could not repress expression of RXRα.CONCLUSION: TPA could induce the degradation of RXRα protein in BGC-823 cells, and this degradation is time-and TPA-concentration-dependent. Furthermore, the degradation of RXRα by TPA is via a proteasome pathway and associated with RXRα translocation from the nucleus to the cytoplasm.
