The result shows that the mixed boundary condition can greatly reduce the calculation area without affecting accuracy of the solution.It is followed by the higher accuracy of Dirichlet boundary condition which makes the boundary error greater when measured points is near the boundary, so we must take a sufficiently large border region.The homogeneous boundary condition has relatively large error, but the use of non-triangle poles devices makes apparent resistivity calculation error become small, because of elimination of the effect on potential difference for the infinite boundary. In inversion, in order to save computing time, homogeneous boundary conditions are often used to perform finite element forward calculation.
结果表明,混合边界条件精度最高,可大大缩小求解区域而不影响计算精度,其次是Dirichlet边界条件精度较高,但测点越靠边界误差会越大,必须取足够大的边界区域,齐次边界条件的误差比较大,但如果采用非二极装置,通过电位差计算得到的视电阻率,由于无穷远边界对电位差的影响基本消除,视电阻率计算误差与混合边界条件下的接近,在反演中,为了节省计算时间,经常使用齐次边界条件进行有限元正演。

Based on thoroughly research, the author draws some following conclusions:(1) the origin of new bilateralism in Asia-Pacific is that each country altered its trade policy to maximize its gains from trade when they faced common external shocks, which is not only to satisfy the restrains of internationally political and economic environments but also to help each government to balance internal political economy when they implement trade liberalization;(2) it has been a common trade policy for each country in Asia-Pacific to set up bilateral trade agreements as soon as possible and as much as possible to obtain hub position in the network of bilateralism;(3) with the inevitable spread of bilateralism, China, as a developing large trade economy, should take first start to guide a favorable process of regional economic integration depending on its booming economy, large domestic market, cheap labor price and abundant natural resources in aim to get much more benefits and advantages.
经过笔者研究,《亚太新双边主义的政治经济学分析》一文得到如下结论:其一,亚太新双边主义的兴起是20世纪末亚太地区各经济体在面临外部冲击的情况下,权衡内部政治经济,选择在当前国际政治经济环境的约束下能够最大化自身利益的贸易政策的必然结果;其二,尽可能快尽可能多地签订双边自由贸易协定,谋求新双边主义中的"轮轴国"地位已经成为各经济体今后较长时间内对外贸易政策的共识;其三,区域经济一体化中的新双边主义趋势已经不可避免,中国作为发展中的贸易大国,应该凭借不断增长的经济、广阔的国内市场、廉价的国内劳动力和丰富的国内资源,发挥先发优势,谋求以我为主的区域经济一体化进程,争取有利的战略地位和更多的利益。

The observational and calculated results are well matched. The calculated mean diameter, mean square-root diameter, mean cube -root diameter and liquid water content are all well matched with the observational results; In the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region. It is found that F-100, 2dc, and 2dp's particle concentrations increase in leeward region, but rising extent is different, which is likely to be due to difference of seeding effect time.
拟合值和观测值吻合的较好,计算出的平均直径、均方根直径、均立方根直径和粒子浓度与观测值也比较吻合;本文对两组个例的催化影响区域及可能采集到相应值的下风方区域进行了分析,催化下风向影响区的F-100、2DC、2DP的粒子浓度比背景值都有所增加,但是增加的幅度不同,应该是催化响应时间的原因。

The shape information of surveillance objects is represented as macro-block coordinates. The temporal redundancy is eliminated by motion estimation within the surveillance region in the reference frame. Since the number of luminance levels is reduced due to enhancement process, the residual error of motion estimation is compressed with lossless entropy coding.
监控对象的形状信息表示为宏块坐标;监控对象之间的时间冗余通过运动估计来消除,但搜索范围限制在前一帧监控对象区域之内;由于增强处理使得监控区域的灰度级减少了,所以对运动估计的残差进行无损熵编码。

The results are displayed vividly in virtual scene which is established with program language of Visual C++ and OpenGL. At present flow field simulation manner mostly has time delay, deficient controllability, so this paper brings forward the methods of drawing flow velocity vector graphics with OpenGL in the 3D virtual scene to simulate and analyze flow field. At the same time cross section and flood analysis are completed. Accordingly, it assists flood flow field visualization and provides the more effective analysis method for the flood mathematics model research and application.

We present an efficient approach for generating the correspondence between two homeomorphic 3D polyhedral models. The user can select vertices on the polyhedra to decompose the boundary of each polyhedron into the same number of morphing patches. Further, the user can specify the feature points on the morphing patch pairs to improve the morph. After the morphing patch pairs are be mapped to 2D regular polygons, they are merged and reconstructed to generate a morph. In the main procedures of our approach, we propose an easy mapping method and a foldover-free warping technique. And we also propose a most efficient merging algorithm. The merging can be completed in O.
