The main usefulness of the tourist area life cycle is to seek common regular issue on space trend of tourist development. It is not a long time for the theory coming into being. It contributes to describing and forecasting the developing track of tourist area and to guidance the plan.

旅游地生命周期理论的主要作用在于探寻旅游地空间发展趋势方面的一般规律性问题，它的产生时间不长，作为一条理论所具有的贡献有：描述、预测旅游地的发展轨迹，以及对规划的指导作用。

This manner can form continuous arrangement effect of hoop bar with less space, and be fit for concrete restricted by stirrup. It also can reduce the concrete crack arised by retortion in the region of frame column, and improve the ductility capability under the earthquake. The construction quality of frame column is improved simultaneously.

该布置方式形成连续且间距较小的箍筋布置效果，有利于发挥箍筋对混凝土的约束作用，减小各种因素可能引起框架柱扭转而在柱非加密区产生的裂缝，改善柱中部区域在地震作用下的延性性能，同时可以提高框架柱的施工质量。

In this paper, the authors classify the problems into landslide, rockfall and collapse of river bank, and relevant influence factors, for example, geo-material properties, weathering and surface/ground water, and finally suggest some control measurements.

文章根据多年积累的大量实际资料分析研究，总结了南充市区的主要斜坡工程地质灾害类型为滑坡、崩塌及岸坡失稳。其中以滑坡最为常见；影响斜坡工程地质问题产生的主要因素为岩土性质、风化作用和水的作用；针对不同的斜坡工程地质问题，提出了具体的工程防治对策。

It is thought that the channel bay line evolution processes can be divided into four stages. The first stage is soon of the sea level stable when the bayhead mountines are eroded and developed abrasion geomorphy and the productive materials were transport into the bay deposition by the tidal current and wave current and were reworked into gravel dams. The second stage is characterized by the fluvial output sediments and eroded sediments mixed deposition in channel bay and developed marine accumulation plain and sand riges in the plain under the wave reworked. The third stage developed clay silt marine accumulation plain under the action of the channel current and the wave action is very limited. The fourth stage is marked by human being reclaim which result in the channel bay filled and evoluted into a strait arce coast.

文章认为，峡道海湾的充填经历了四个阶段，第一阶段以峡道海湾湾顶山体在波浪作用下产生的侵蚀物质充填为主，发育了海蚀崖、海蚀洞、海蚀穴等侵蚀地形和湾顶砂砾石堤等堆积地形交替的峡道湾顶地貌，第二阶段以河流输出物质和峡道湾岛屿、礁石侵蚀物质在潮流作用下向峡道湾输运，由潮流和波流共同沉积为特征，发育海积平原，部分粗颗粒泥沙在波浪的改造峡，发育平原沙堤，第三阶段以河流输出物质为主，在涨落潮流搬运下进入峡道和峡道湾沉积，在峡道湾中发育以淤泥质粉砂为主要物质的海积平原，第四阶段以人类围涂造田为标志，加速峡道湾的充填过程，使峡道海湾最终趋于夷平，形成顺直均衡的弧形海岸。

Saprophytic fungi are fundamental to decomposition and energy flow of mangrove, additionally, their potential toxicity also exists. Pathogenic fungi have significant effects on mangrove survival, growth, and fitness. Endophytic fungi, the most prolific source of diverse bioactive compounds found among that of mangrove-associated fungi, are found in most species of mangroves.

其中腐生真菌对于红树林生态系统的降解和能量循环方面起着重要的作用，另外，它们也会产生一些毒素：寄生真菌对于红树林的存活，长势和健康程度起着重要的作用；而内生真菌分布于大部分红树之中，所产的活性物质是红树林真菌中最丰富的。

Photoelectron rise and decay signal curve of various emulsion samples, which is exposed by 35ps short pulse laser, is measured. The corresponding relation of photo-absorption saturation curve and the photographic characteristic curve is obtained, and farther the quanta efficiency of free photoelectron is also obtained.

本文从卤化银材料的微观光作用动力学的角度出发，依据微波吸收原理，设计并建立了纳秒量级卤化银材料光生电子信号检测装置，在超短脉冲激光作用下，测量了不同材料的光电子产生与衰减信号曲线。

Under the function of semipermeable membrane, a reasonable adjust of the drilling fluid activity to be less than formation water activity will transfer water from formation to drilling fluid because of the existence of osmosis pressure.

在半透膜的作用下，适当调整钻井液的活度小于地层水的活度，渗透压会使地层中的水向钻井液运移，避免或减少因钻井液向地层运移而产生的负面影响，对地层的稳定起到积极作用。

In this model, not only natural convection that is caused by different vertical density, and the baffle effect of shearing stress caused by viscosity is considered, but also the effect of concentration distinction itself to leaky flow is considered

该模型不仅考虑了由于密度差引起的自然对流作用，粘滞性产生的切应力对水流运动的阻滞作用，还考虑了溶质浓度的差异对越流的影响。

Results With different concentration of sodium arsenite 0.5 ～ 5.0 μmol/L, the skin fibroblasts were markedly stimulated, and a dose effect relationship was observed.

结果与对照组比较，皮肤成纤维细胞经不同剂量的亚砷酸钠诱导后，吸光度值均有改变，存在剂量效应关系（P〈0.01）。0.5～5.0μmol／L浓度的亚砷酸钠对皮肤成纤维细胞有明显的增殖作用，而10μmol／L浓度的亚砷酸钠产生明显的毒性作用。
