| 1. | It presents images of electron density distribution inside the object 它可以提供关于物体内部物质电子密度分布的图像信息。 |
| 2. | Inner stress : inner stress is the stress which balances the object interior without exterior stress 内应力:内应力是在没有外力条件下平衡于物体内部的应力。 |
| 3. | Non - destructive testing ( ndt ) is a type of technology that detects and evaluates flaws in material without affecting its internal structure 无损检测是在不损害被探测对象使用性能的条件下探测物体内部缺陷的技术。 |
| 4. | Compton scattering imaging is a radiation imaging technique that forms the image of an object by measuring compton scattering emitted from the object while it is irradiated 康普顿散射成像是通过测量从被照物体中发射出来的康普顿散射线来对物体内部进行成像的放射成像技术。 |
| 5. | This algorithm uses the profiles collected from a number of angles to compute the x - ray attenuation coefficient of a cross section inside the body , then reconstruct the image of the cross section 该算法利用从各方向测量出来的投影值求出物体内部受检断面各点的x射线衰减系数,从而重建出整个人体横截面的图像。 |
| 6. | In this way , the intrinsic state and structure of objects can be perspective ; the images and movements can be simplified and purified ; the limitation of time and space are breached ; some natural phenomena are imitated 能透视,剖视物体内部的状态和结构;简化、纯化物体的形象和运动;突破时空局限,模拟、仿真某些自然现象。 |
| 7. | When the theory of temperature in solids 、 the equivalent tension - relaxation curve of final temperature , and the equivalent shear - relaxation curve is known , then the non - stationary stress is calculated 在非定常热应力计算时只要确定物体内部各点的温度历史,及其终态温度等效拉伸松弛曲线、等效剪切松弛曲线,便可计算出物体内各点的瞬态热应力。 |
| 8. | All algorithms that introduced hi my paper focus on the hollow hull of object , and the calculations are a series of intersection of face and line that have no ply . and by employing the topology information that come with the points since their generation , we can get the surface polygonal mesh without triangulation and reduce the time used in reconstruction of visual hulls and help to realize real - time rendering 本文提出可见壳的生成算法都是建立在无厚度的平面直线求交计算上,完全避免了对物体内部的冗余区域的计算,同时利用物体表面点集与生俱来拓扑信息,恢复物体表面的多边形网格,在一定精度范围内可以避免对散乱点集进行三角剖分,减少可见壳的生成时间并有助于实时绘制的实现。 |
