Results show that floes' VC and D at the surface water were closely related to current velocity; and the peaks of VC lag those of the current velocity. The lag variation during ebb and flood tides is 10-30min and 30-50 min, respectively. Current velocity at 50 cm/s is a turning point of D vs. vertical average current velocity, before the point, Dm increases with current velocity, and decreases after the point. Similarly, VC at 75μl/L becomes a critical point in the surface water, below the point, D increases with VC, and above the point, D stabilizes.Δp is D dependent, larger floes have much lower Δp than smaller floes. Both D and Δp of floes affect ω. In the surface water during spring tide and neap tide, a power exponent relationship exists between Δp and D, and ω and D.

研究表明：①长江口徐六泾表层絮凝体体积浓度主要受水流流速影响，再悬浮现象明显，体积浓度过程线滞后流速过程线，落潮期间滞后10-30min，涨潮则滞后30-50min；②小于一定流速时絮凝体平均粒径随流速增大而增大，大于一定流速时絮凝体平均粒径则随流速增大而减小，徐六泾夫、小潮表层絮凝体在50cm/s的垂线平均流速时出现平均粒径与垂线平均流速关系的转折；③徐六注大、小潮表层絮凝体平均粒径在体积浓度75μl/L时出现平均粒径与体积浓度关系的转折，体积浓度小于75μl/L时粒径随体积浓度增加而增大，超过75μl/L时粒径随体积浓度的增加变化不明显；④絮凝体有效密度由粒径大小控制，粒径大，有效密度小，反之亦然，粒径和有效密度共同决定絮凝体静水沉速，有效密度和沉速与平均粒径之间均存在良好的幂指数关系。

However,some of the faster nonimpact printers can produce multiple copies of the same report faster than the time it takes impact line printers to do a single run with mult-plypaper 2 But user should be careful about possible "head crash",which means the surface of the read/write head or particles on its surface come into come into contact with the disk surface,causing the loss of some or all of the data on the disk 3 Like music CDs,a CD-ROM is a read-only disk that the disk's content is recorded at the time of manufacture and cannot be written on or erased by the user.

应该是这样： 1然而，其中一些更快nonimpact打印机能产生多份副本，同时报告速度比所花费的时间影响线打印机做一个单一的运行与多plypaper 2 ，但用户应小心可能的"头部撞车"，这意味着表面上的读/写头或微粒表面，其生效接触到磁盘表面，从而导致丧失部分或全部的数据，就磁盘三喜欢音乐光碟，唯读光碟，是唯读磁盘磁盘的内容，是记录当时的制造和不能写上或擦除由用户。

First, we extract the boundaries between two different materials by weighting with gray-level gradient,and only voxels on these boundaries participate in the generation of each image, so it drastically reduces the rendering time. Second. We think the voxels on boundaries as the mixture of different materials,so in every voxel there is a surface. We use the oriented cube-interpolation technique to get the intersection point of viewing orientation and the surface in the voxel, then compute the surface normal of the intersection point. We use the normal to shade the voxel in order to improve the image quality.

首先，采用灰度梯度加权提取出三维数据场中不同物质间的边界，根据显示的需要只对这些边界上的体元赋予相应的阻光度并进行光亮度合成计算，因而可大大减少计算量，提高显示的速度；将边界上的体元作为不同物质的混合体，采用与方向有关的三线性插值来计算视线方向与体素内等值面的交点，根据交点的法向量进行光照效应计算以提高显示图像的质量；最后用投影成像法显示最终的图像。

Within GVS, a terrain surface is represented internally as a mathematical structure and offers the user sophisticated "intersection" and "collision detection" capabilities including inquiries about height-of-surface, orientation of surface, range to intersections, information about which object instance in a scene may have been intersected, which "subobjects" have been intersected, even down to the individual user defined composition types (e.g., water, mud, metal) which have been intersected.

在GVS中，一个地形表面是作为数据结构在内部描述的，碰撞检测包含查询表面高度，表面方位，交集范围，关于场景中的哪个实体虚像应该已经被碰撞，哪个"subobjects"已经被碰撞，甚至到个别用户定义需要被碰撞的物体成分类型。

The error compensation is introduced in the interpolation algorithm to increase the interpolation point's solution precision in the cutting direction of the parametric curved surface. The reasonable simplification of the computed result of the interpolation point's parameter value is carried in the operation process by focusing on the character that curvature of slow-varying parametric curved surface changed slowly and the feature that the scanned profile of translational scanned curved surface is parallel along the scanned line.
