Previous studies on erosional relations between inter-gullied and gullied lands have mainly concentrated on exploration of water and sediment relations, with few quantitative studies of evolution relations between inter-gullied land and gullied landform erosion in small catchments. This paper, using information from a 1:5000 digital orthophotomap (DOM), digital elevation model (DEM), and topographic map of the same period and of the same scale, quantitatively analyzes the impact and interactions of inter-gullied and gullied land geomorphologic characteristics on the dissected extent of a catchment using orthogonal polynomial regression analysis. Results indicate that gullies play a leading role in the catchment morphologic evolution and extent of cracked ground surface. When inter-gullied land areas are the same, a 0.1 km2.gullied land area has the maximum effect on the erosive evolution intensity of the catchment cracked degree. The smaller the catchment area is, the greater the extent of cracked ground surface and gully intensity would be. The geomorphologic evolution mechanism of gullied catchments can be explained as a function of geomorphologic indicators of inter-gullied and gullied land characteristics.

提出了一种基于IEKF序列图像分析的航天器间相对状态单目视觉测量方法.该方法利用具有正方形几何结构的4个目标特征点在物体坐标系中的空间坐标及它们在像平面上成像点的图像坐标,根据估计理论,采用迭代扩展卡尔曼滤波(iterated extended Kalman filter, IEKF )方法解算出目标航天器与图像传感器的相对状态.试验结果表明:该方法不仅使作用距离大大提高,而且极大地提高了测量的稳定性.该测量方法可直接用于航天器编队飞行及空间站交会对接过程、空间监视、目标拦截等应用领域中航天器间相对状态测量.

Objective To examine the immunoregulation of Celastrus orbiculatus extracts (COE), a traditional Chinese medicine, on maturation and function of dendritic cells (DCs) in vitro and in vivo. Methods In vitro, after treated with COE in different nontoxic concentrations (0, 10, 2., 40, 80, and 160 μg/mL) for 5 d, the surface immunological molecules and cytokine secretion of mice bone marrow-derived DCs in response to COE were analyzed by flow cytometric analysis (FACS) and enzyme linked immunosorbent assay (ELISA), respectively. In vivo, mouse hepatoma cells (Hepa1-6, 1 × 106) were injected sc and were treated with different dosages of COE (10, 2. or 40 mg/kg/d). Effects on tumor growth were determined by tumor volume and histology analysis after 2. d administration of COE. The relative proportions of mature DCs and CD8+ T cells were measured in mononuclear cells that had been isolated from spleen by FACS. Results COE stimulated IL-2.and IFN-γ secretion of DCs, simultaneously enhanced the maturation of DCs by enhancing immunological molecule (CD40, CD80, CD86, H-2.b, and I-Ab) expression in a dose-dependent manner. Furthermore, the chemotactic responses of DCs were significantly higher in COE-treated than untreated DCs, in association with higher chemokine receptor 7 expression. Furthermore, COE increased DCs produce IFN-γ and IL-2.in a dose-dependent manner when the concentration of COE less than 40 μg/mL, decreased DCs produce IL-10 and IL-4 also in a dose-dependent manner. In in vivo studies, COE can not only suppress growth of malignant hepatocellular carcinomas but also stimulate maturation of DCs, associated with strongly enhanced CD8+ CTL responses. Conclusion These data provide new insight into the mechanism of action of COE and indicate that the stimulation of maturation and function of DCs by COE contributes to its immunoregulatory effects.
