| 5. | It is easily to measure the volume of the discrete - phase in two - phase flow in a pipe based on the 3d reconstruction image . the 3d reconstrution images and the result of volume indicate the more sections interpolated , the better the 3d reconstruct image will be , but not the less the volume error will be
重建的三维图像和体积计算结果表明，随着插值轮廓数的增加，重建的三维图橡质量得到了提高，但只增加插值轮廓数量并不能明显的喊少体积误差。 |
| 6. | Since it is difficult for the cable or beam model to consider the large deformation in the pipe crossing section , the fem analysis with shell element has been proposed to investigate the response of pipe . takada ( 2000 ) proposed a simplified design formula to obtaining the maximum strain in steel pipes based on the parametrical study using a beam - shell hybrid fem
现在的抗震规范和有关研究中，还很少有估计大变形时管子内的应力应变的方法，虽然2000年高田至郎等人基于壳有限元模型的参数研究提出了设计用的简化计算公式，但在他们的分析模型中存在一些问题有待改进。 |
| 7. | Depending on different natures of materials to be conveyed , the pipe inner surface can be lined with a metal either the same as or other than the pipe base metal by means of the plastic deformation complex technique so as to meet the following requirements : 1 ) increasing both corrosion resistance and wear resistance of the pipe inner surface ; 2 ) reducing the friction factor and the resistance against the materials being conveyed in the pipe line ; 3 ) easy processing , installation and maintenance of the pipe line
根据输送物料的性质，采用塑性变形复合方法在管道内壁镶衬异种或同种金属管，可以实现以下目的：增强管道内表面的耐腐蚀性和耐磨性；降低摩擦系数，减小物料的输送阻力；便于管道的加工、安装和维修。 |
