托木尔峰自然保护区地衣的补充研究

我们根据多年的研究并结合前人的工作进一步地整理了分布在新疆托木尔峰自然保护区的地衣种类。分析该地区的地衣种有１２０个，分别隶性于４９属，其中有１１个变种和４个变型。调查中我们还发现该地区地衣随着海拔高度的升高而有所不同，北坡和南坡也有明显的差异。     

东祁连山几种高山杜鹃的种群垂直分布对策

东祁连山大阴坡几种杜鹃种群在不同海拔高度上的垂直分布对策是各物种生态位重叠与分离的结果:千里香杜鹃和头花杜鹃为海拔3300m以下梯度内的优势种;陇蜀杜鹃在海拔3300m以上更湿冷的范围内开始增加,并占绝对优势;烈香杜鹃在3400m时分盖度最大,在低处与千里香杜鹃和头花杜鹃伴生,在高处与陇蜀杜鹃伴生。     

蛋鸡舍湿墙降温设施的应用效果分析

通过对某鸡场三种不同的纵向通风与蒸发降温设施在夏季的使用效果的观察，证明纵向通风加湿帘系统在降低鸡舍环境温度、缓解热应激、降低鸡群生产性能下降幅度等方面效果最好。纵向通风与湿墙降温系统也具有一定的效果，从性价比来讲也不失为一种好的环境控制措施。

结构动力分析的竖向子结构法

从工程设计应用出发提出一种高层建筑结构三维直接动力分析方法，该方法通过利用子结构技术将高层建筑结构规模庞大的空间整体分析模型沿超重方向划分成若干个规模相对很小的竖向子结构，从而最大限度地降低了三＝维动力分析中整体结构动力平衡方程的阶数。     

青冈常绿阔叶林的太阳辐射分布特征

通过野外定位观测，对青冈（Ｃｙｃｌｏｂａｌａｎｏｐｓｉｓｇｌａｕｃａ）常绿阔叶林太阳辐射分布特征进行了研究．结果表明，青冈林反射辐射、透射辐射和吸收辐射的季节动态与太阳总辐射的季节动态相似，各辐射分量均为夏季最大，冬季最小，四季中群落的反射率、透射率和吸收率分别为１６％～２２％、９％～１２％和６７％～７４％．林冠层对光强的衰减率达８０％～９０％，且衰减率随太阳高度角的增大而增大．群落中部以下光强的衰减很小     

441千瓦双船底拖网网口高度与网口周长的关系

本文报道了１９８６￣１９９２年期间对４４１ｋＷ渔船使用的１顶度拖网网口高度的海上实测结果。结果表明：网口高度是网口拉直周长的５．５￣７．３％。两者的关系可用经验公式表示为：Ｈ＝０．２６０９Ｌ＾０．７３４４。     

回转窑燃烧图像中火焰区的动态标定

提出一种动态标定火焰区的方法，以彩色图像中的红色绿色成份的线性加权组合图像作为研究对象，利用其垂直灰度投影曲线和水平灰度投影曲线确定火焰区的重心，采用由内到外扩散的办法确定火焰区的左右边界和上下边界，标定火焰区。实验表明，该方法能正确地动态标定出火焰区，并能满足实时处理的需要。     

The Vertical Distribution of Soil Seed Bank and Its Restoration Implication in an Active Sand Dune of Northeastern Inner Mongolia,China

Although the functions and characteristics of soil seed banks in topsoil layers have been described for various ecosystems, the spatiotemporal pattern of the seed bank in deep soil and its ecological implications for vegetation restoration of active sand dune have not been fully explored. In 2007 and 2008, seed densities with regard to dune position, soil depth and season were investigated on an active and a stabilized sand dune of northeastern Inner Mongolia, China. Seeds in the 0–10 cm topsoil layer accounted for 60% of total soil seed bank on the stabilized sand dune, while more than 40% of seeds were stored in the 50–100 cm layers on the active sand dune. Seed density declined significantly with soil depth on the stabilized sand dune, but it was relatively constant across the 0–100 cm soil profile on the active sand dune. Seed density fluctuated with soil depth on the active sand dune suggesting that seeds were either relocated upward or downward over time. Seeds of annual non‐psammophytic species accounted for the majority of soil seed bank on the stabilized sand dune, while pioneer psammophytes contributed more to the soil seed bank of the active sand dune. Our data suggest that seeds in the deep soil layers of active sand dunes account for a large proportion of the whole soil seed bank. Because of the effect of wind erosion, seeds in deep soil could be gradually exposed to shallow soil layers and potentially contribute to population recruitment and vegetation restoration on active sand dunes.

The Transportation and Lifting Facilities in Chongqing and the Industrialised Housing

This article introduces that there are good basic conditions and big development space for the industrialized housing development in Chongqing Municipality-the biggest municipality in the country.And it introduces the capabilities of horizontal transportation by land or sea and vertical lifting in Chongqing. And it puts forward that is more economical, reliable and safer than which has the advantages of best weight lifting capacity, service radium. Lifting height and smallest site occupation and the assemble of bigger components even the whole industrialised house.
