Then, Triangular Irregular Net ( TIN ) is established by the principles of Delaunay on the base of scattering 3D spacial points ( x, y, z ) whose 3D coordinates consist of the 2D coordinate and the value of residual chlorine; 再对由节点平面坐标和节点余氯含量构成的三维空间散点(x,y,z),用Delaunay三角网构网原则建立不规则三角网(TIN);
When the motion of the flux tube is oblique direction, most passage positions appear irregular FTEs, and the signatures of Bz is bipolar distribution. 当通量管在x方向有正或负速度分量即斜向运动时,大部分部位测到的Bx呈不规则变化,Bz表现为双极分布。
It is a highly variable and irregular source with X-ray emission that flickers in a hundredth of a second burst. 它是一个不规则的快速变化的X射线辐射源,每秒钟闪烁100次。
The discussion of irregular field prescription dose calculating method for low and middle energy X-rays 中低能X射线不规则野的处方剂量计算方法探讨
According to the shape of irradiation field, we advance two kinds of dose calculation models separately for high-energy X-ray regular and irregular field, thus achieving the compromise precision and speed. 文中根据照射野形状,将高能X射线分成规则野和不规则野两种类型,通过建立相应的剂量计算模型以取得折衷的计算精度和速度。
