Based on the model of DLA, this paper simulates the process of aggregation's growth for random walk particles from local area on two-dimension Euclidean plane. The aggregation is confined to Euclidean circular plane for large enough particle walking area and far enough partial source distance. The centre of the Euclidean circular plane is on the line between the particle source's symmetric centre and the seed particle, and is more closer to the particle source than the seed particle. Though the rate of aggregation growth is different in different directions, the whole aggregation shows fractal structure.

以DLA模型为基础，模拟研究了在二维欧几里德平面上由局部区域内产生随机运动粒子的聚集生长过程，发现对于足够大的粒子运动区域和足够远的粒子源距离，凝聚集团大体上被限制在欧氏圆形面内，圆心在粒子源对称中心和种粒子的连线上，且比种粒子更加接近粒子源；凝聚集团朝各个方向的平均生长速率虽然不同，但整体仍呈分形结构。

The round, arch wall and hemicycle were with the obvious stress concentration at the top of chamber, close to point of concentration.

The transition radiation faculae on the rear side of a 20m thick target Ta was a smooth round structure with the center brighter than the periphery, indicating incoherent transition radiation and coherent transition radiation, which is close to the results of the theoretical simulations. For a 100m thick target Ta, the faculae was a star-structure and became smaller, which resembles a star-structure of the energetic proton emission. For a 10μm Ta+10m Cu+5m Ta composite target, the faculae was a ring structure and became bigger and non-uniform, looked like two apart faculae.

在厚度为20μm的Ta靶背表面观测到渡越辐射光斑呈现较平滑的圆形结构，而且中心亮度高于周围，这包含了非相干与相干渡越辐射的成分，与理论模拟结果接近；在厚度为100μm的Ta靶背表面观测到渡越辐射光斑呈现出星状结构，光斑较小，与高能质子发射出现的星状结构极其相似；在复合靶背表面观测到渡越辐射光斑虽然也呈现大致的圆形结构，但光斑较大，而且极不均匀，中间有很明显的光斑分裂。

The shape of the Translate Y curve illustrates why.

接近60帧时，曲线是软圆形的。Y平移值逐渐的减少到一点，然后又逐渐增加。

The sphere aggregate model and the circle aggregate model based on Walraven formula can usually be used to approximate gravel aggregates and spherical aggregates, but it can not be applied for detritus aggregates.

球形骨料模型和基于瓦拉文公式生成的圆形骨料模型基本上能够接近卵石、砾石等球状或浑圆状的骨料，但与一般碎石骨料的形态差异较大。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
