A visible model of stand based on image of tree is introduced in this paper.A prototype of tree,which is with typical orm and structure of this species,is treated as the average tree in a stand.Using the image resampling technology,the image of this prototype tree can be magnified or reduced to different scale in order to simulate each tree in this stand.The coordinate of pixel and the scale of each tree in a projection plane is calculated by means of the projection principle.The scaled images of all trees are...

A visible model of stand based on image of tree is introduced in this paper.A prototype of tree,which is with typical orm and structure of this species,is treated as the average tree in a stand.Using the image resampling technology,the image of this prototype tree can be magnified or reduced to different scale in order to simulate each tree in this stand.The coordinate of pixel and the scale of each tree in a projection plane is calculated by means of the projection principle.The scaled images of all trees are moved to their corresponding coordinates in the display plate and the stand image is formed.This visible stand model can quickly provide more really stereoscopic image of the stand.An application software based on this model can be developed for the design and simulation of the landscape of forests and plants.

该文介绍一种基于树的图象的林分三维可视模型.以一株典型形体的树木为原型代表林分的平均木,应用图象重采样技术对该原型木图象按比例缩放生成林分中各株林木的图象.根据投影原理计算每株林木在投影平面上的象素坐标和缩放比例,对各林木图象再次缩放后移动到林木的平面坐标位置合成一幅有立体感的林分图.与基于规则几何体的和基于树的三维造型的林分三维可视模型相比,这种方法产生的林分立体图真实感强,速度快,适合开发成应用软件用于森林与植物景观的设计和仿真.

In this paper,the composition methods for places of Petri nets are presented.The conditions for preserving static properties(such as structural boundedness,repetitiveness,conservativeness,consistency,S invariants and T invariants,et al.)and dynamic properties (such as reversibility and lineness,et al.)of Petri nets after these operations are discussed, respectively.These results are useful for composition and analysis of complex systems.

In“Excess Pressure Seed Method"of synthesis diamond,we have observed the phenomenon that crystal seed grew floating up in the melting metal solvent under high temperature and high pressure by appropriate designing the composite cavity assembly,designing the way and the location of crystal seed plant and selecting of composite condition.The phenomenon is caused by the difference of specific gravity between metal and carbon.In the experiment,a close relation is shown between the crystal seed floating up phenomenon and the composite condition.An appropriately high temperature and pressure and necessary.The effect of buoyance has some influence on the formation of the diamond polycrystalline and crystal shape in excess pressure seed method. Key words: diamond;excess pressure;crystal seed;effect of the buoyancy force avy metals in pore water of reduction phase sediments and it forms sulfide with heavy metals again,and effects the chemical species of heavy metals in sediments.Study has been proven to be the dominant phase AVS reacting with heavy metals.Change of AVS can occur either through human activities,such as dredging waterways and harbors,or by natural phenoment,such as resuspension due to storms and changes in sediment Chemistry.The study passed a series of laboratory aeration experiments for 32 days,effect of probe the change of sulfide content on lead.The result shows that aeration of sediments results in rapid decrease of the (AVS).At the same time,distinct changes also occurred in the values of Pb, E h,DO,and pH.

在合成金刚石的“过剩压晶种法”中,通过适当设计合成腔组装、晶种植种方式及位置、合成条件的选择,观察到在高温高压条件下,晶种在熔化金属触媒中上浮并生长的现象。这一现象是金属与金刚石比重不同而引起的。实验发现,晶种上浮现象与合成条件有密切的关系,适当高的温度与压力是必要的。浮力效应对过剩压晶种法中,金刚石的连聚晶形成及晶体形态,都有一定的影响。
