Having noticed that the number indicating the greatest depth was apparently in the centre of the map, I laid a rule on the map lengthwise, and then breadthwise, and found, to my surprise, that the line of greatest length intersected the line of greatest breadth exactly at the point of greatest depth,notwithstanding that the middle is so nearly level, the outline of the pond far from regular, and the extreme length and breadth were got by measuring into the coves; and I said to myself, Who knows but this hint would conduct to the deepest part of the ocean as well as of a pond or puddle?

发现那记录着最大深度的地方恰恰在湖心,我用一根直尺放在最长的距离上画了一道线,又放在最宽阔的地方画了一道线,真使人暗暗吃惊,最深处正巧在两线的交点,虽然湖的中心相当平坦,湖的轮廓却不很规则,而长阔的悬殊是从凹处量出来的,我对我自己说道,谁知道是否这暗示了海洋最深处的情形之正如一个湖和一个泥水潭的情形一样呢?

Methods Marshland areas near high endemic villages of schistosomiasis in the Poyang Lake region were selected. Corresponding map was digitized and (Landsat 5 TM) the image was corrected according to the digital map. The image where water and land shifted during floody and dry seasons was extracted and classified by unsupervised method. The image in dry seasons was calculated by both Normalized Difference Vegetation Index and Tasseled Cap model. Traditional snail survey was done at the same areas and recorded the geographic position by Geographic Position System. Some cultured lands inside the embankment and water pound in marshland areas were selected as control group. Results The image of pilot areas was classified into 10 classes.

方法选择鄱阳湖区内3个洲岛型血吸病重度流行村周围的洲滩地图进行数字化,在数字化地图的基础上分别对两张Landsat 5TM卫星遥感片进行校正,并提取出冬陆夏水洲滩部分,运用ERDAS IMAGINE软件对此洲滩进行计算机非监督分类、校正植被指数(Normalized Difference Vegetation Index, NDVI)和穗帽湿度变换指数(Tasseled Cap, TC)模型计算;用传统方法进行螺情调查,卫星定位仪记录有钉螺点的经纬度,同时选择部分堤内的农田和水溏作为对照点。

As for CD8~+ T cells,the 3-D reconstruction map and grayscale map, which imply the distribution mode/pattern of membrane receptors,also illustrate that CD8 and CD69 receptors inhomogeneously distributing on cell membrane and forming nano-/microstructural domains:5 Atomic force microscopy is a rapidly developing tool recently introduced into the evaluation of the age of bloodstains,potentially providing useful information for forensic investigation.
