Using this scheme, the triangle satisfies Delaunay condition, and the unstructured grids are optimized.

研究了非結(jié)構(gòu)網(wǎng)格的局部加密問題欧美一级免费性爱，可以采用局部增加節(jié)點(diǎn)的方法国产偷情在线、采用局部極坐標(biāo)網(wǎng)格的混合加密方法。

The advantages of this new method are:(1) The field conductivity distribution function is fitter the actual condition than tradition methods:(2) On the condition of triangle elements cut of field, making the calculation speed increase in large degree than tradition methods.

與單元電導(dǎo)率重建算法相比国产欧美第一页，節(jié)點(diǎn)電導(dǎo)率重建算法的優(yōu)點(diǎn)有：(1)使場域電導(dǎo)率分布函數(shù)更符合實(shí)際情況日韩美女福利禁止观看网站视频免费，克服了傳統(tǒng)算法中對電導(dǎo)率作離散化處理的缺陷；(2)當(dāng)場域采用三角形單元剖分方式時日本三级网站，在場域的剖分密度保持不變的情況下看av网址，可以大大提高重建計算的速度；(3)在場域采用三角形單元剖分方式時欧美高清国产在线有码，場域的剖分密度可以比以前加大一倍3P视频国产，在不降低重建計算速度的前提下，可以改善重建計算的精度中文自拍日韩在线视频观看网站；(4)由于重建的是所有節(jié)點(diǎn)的電導(dǎo)率一区视频免费观看，避免了先前單元電導(dǎo)率重建圖像中"階梯"狀邊緣和"鋸齒"狀邊緣的出現(xiàn)，明顯地改善了圖像的視覺效果欧美性爱调教美女视频播放三区。

By analyzing the characteristics of the several common load harmonic sources, this paper inducted the resistance formulas, sequence resistance and sequence impedance matrixes of tri-phase universe loads, star and triangle connection loads under harmonics condition.

It proposed that during the structural deformation (about in the Yanshan～Himalaya movement epochs), under the control of the right triangle boundary condition and in the united stress field in which the three boundaries were acted on by three side forces vertical to them at the same time, petroleum/gas substances in the block that had been in fluid/gas state at that time might move driven by high pressure driving from the side parts to the center of the triangle block along with deformation of the rock beds, forming industrial gas fields in the suitable structure parts of the triangle block.
