Zero velocities on the cylinder were satisfied at the node points. 圆柱上速度为零在节点上满足。
Therefore, study on the container rail-water intermodal transportation network optimization, reasonable container rail-water intermodal transportation organizations and investment and construction of node points is particularly important. 因此,通过对集装箱铁水联运网络进行优化,进行合理的集装箱铁水联运组织和结点站投资建设变的尤为重要。
Based on the structural cyclic symmetric property of the cyclic symmetric structures, the eigenvalue equations of the whole structure is uncoupled with the cyclic symmetric conditions of node points of the sectors and the complex constrained conditions of the displacements of the node points. 利用循环对称结构的循环对称性,通过扇区结点循环对称条件和结点位移复约束条件,解除结构特征方程中各个扇区之间的耦合关系;
A further study given by the paper shows that so long as appropriate starting point is selected and reasonable locations of node points are positioned, two-dimensional quadratic splines always give precise approximation to many typical types of two-independent-variable chemical engineering curves. 本文还考察了将二维二次样条用于逼近各类典型的二维化工曲线族的误差,发现只要选取恰当的起始点和合适的节点布置,一般均能获得满意的精度。
A regression model for the relationship among re - reddening temperature, time and distances from different node points to the surface is thus obtained in re - reddening zone. 在返红区域回归出返红温度随经历时间和各点到表面距离的变化规律的关系模型。
