| 3. | During the previous analysis of asphalt pavement structure with cracks , the stress intensity factors were usually calculated approximatively using plane strain model for some limitation . however , the assumptive load of this model is not coincident to the practical load 在以往分析含裂缝的沥青路面结构时,由于条件的限制,通常是假设沥青路面结构近似为一平面应变模型,但是这种模型所假设的荷载与实际作用的荷载有较大的区别。 |
| 4. | Multi - carrier adaptive multilevel modulation technology maybe regards as a kind of transform combination by n single - carrier adaptive multilevel modulation technology approximatively . multi - carrier transmission can improve performance of the attenuation consumedly but single - carrier transmission ca n ' t 多载波自适应多元调制可以近似看成由n个单载波多元调制的变换组合,但由多载波传输对衰落的改善是单载波传输所不能比拟的。 |
| 5. | These relations are ambiguous and are n ' t able to be formulated today . making use of the artifical neural network ( ann ) , those relations between dsps and damage / health status are ascertained approximatively . by monitoring these dsps in structures , healthy status could be supervised 这些标识量和结构的损伤状态存在着确定的但是目前无法解析出来的映射关系,通过神经网络可以较准确地来拟合这种标识量和损伤失效状态之间的关联。 |
| 6. | The distance from figure center of the parabola to the potential slide surface is less than half of the section length . mechanical conditions of this method include not only force equilibrium but also moment equilibrium . as for the beam - on - foundation , its pressure can be calculated by homogeneous hypothesis or winkler foundation hypothesis or infinite half elastic foundation hypothesis on the pulling anchor - cable step and by coulomb active earth pressure theory approximatively on the long term working step 对于桩在滑面以上段所受的坡体荷载,提出可按形心偏下的抛物线型分布模式计算,并在满足力的平衡条件的同时还满足力矩平衡条件;对于地梁上作用的坡体荷载,提出在锚索张拉阶段可按均布或温克尔( winkler )地基假定或弹性半无限体地基假定来计算,在工作阶段则一般可以近似按库仑主动土压力理论计算。 |
| 7. | And the basal laws of these changes are also summed up in the paper . in the paper , rectangle concrete cross section with steel band to replace approximatively the mutil - limb steel tubular truss section is brought up to calculate and check calculation in the cfst arch bridge . the method has been verified partially by the procedure algor93 and can be applied in actual engineering 本文提出在钢管混凝土拱桥的内力计算及设计验算时,可用带有钢带的矩形混凝土截面近似代替多肢桁式钢管混凝土拱截面,并通过algor93程序进行计算分析,在部分方面验证了这种近似替代的可行性,为实际工程设计中计算多肢桁式钢管混凝土拱桥提供了一种可行的计算模式。 |
| 8. | By an imaginary uniform sampling on the original triangle mesh , our algorithm makes the 3d point set using in icp algorithm not only approximatively uniformly distribute in the measured object surface , but also possess of more information of the object surface than classical icp algorithm 通过在三角形网格上按面积均匀分布的假想抽样,在没有明显增加计算复杂度的情况下,使得代入icp算法的3d点集,不仅是近似均匀地分布在物体表面上,而且更加充分地反映了被测物体的表面信息。 |
| 9. | Reference to the convention means of the analysis and research for energy spectrum hardening and photon scattering in internal and external , and based on the physical mechanism of radial interacts with matter , this paper approximatively deduce a theoretical formula of correction of energy spectrum hardening and scattered radiation in transmission industrial x - ray computerized tomography from a ideal model . and presented a correction computer program 本文在分析研究国内外有关射线能谱硬化和散射修正问题的分析方法及其研究状况的基础上,从射线同物质相互作用的物理学机理出发,从理论上近似推导了x射线能谱硬化和散射修正计算公式,建立了散射修正的分析模型,并编制了相应的计算机修正程序。 |
