| 1. | This paper presents a theoretical model for the coefficient of restitution calculation of point impact 摘要建立了一种计算点接触正碰撞恢复系数的理论模型。 |
| 2. | Also note that you can calculate the dot product only if the two vectors have the same number of components 另外请注意,只有当两个矢量的组件数相同时,才能计算点积。 |
| 3. | After the lode disappearance , the stress of each calculation point in the road diminishes quickly , particularly the verticial stress 当载荷消失后,路面内各计算点的应力值迅速减小,尤其竖向应力减小幅度更大。 |
| 4. | Moving least squares interpolants do not pass through the data because the interpolation functions are not equal to unity at the nodes unless the weight functions are singular 但是,移动最小二乘法的近似函数不一定精确地通过计算点,除非使用奇异的权函数。 |
| 5. | Under vertical dynamic loading , the max deflection value will decrease with the loading time diminishing and also that of the stress of asphalt pavement 路面最大弯沉值与路面内各计算点的应力最大值出现时间不同,应力在载荷消失后立即达到最大值或延迟时间非常扳,而弯沉最大值延迟时间相对较长。 |
| 6. | This is a disadvantage of efgm as it suffers from problems in the imposition of essential boundary conditions and the application of point loads . however , these do not disadvantage efgm significantly 由于移动最小二乘法的近似函数不一定精确地通过计算点,从而使本质边界条件的施加和集中载荷的处理变得复杂。 |
| 7. | The approach includes : obtain cutter location points from cutter contact points ; interference pretreatment by convex box of data cloud and reducing check area ; interference detection and tool - position correction based on data cloud 通过计算点云模型的曲率,确定切削步长和行距,采用基于点云的干涉检查模型,推导出干涉处理的解析式,得到了无干涉加工刀轨。 |
| 8. | 2 . with the method of multiple point regression , a general formula was established to estimate the annual precipitation at different elevation . rr = 1056 . 9 + luhzr in the equation : r x is the increasing rate of annual precipitation , and unit is mm / m 根据多点回归建立起估算区境任一海拔高度年降水量的通式: rz = 1056 . 9 + r hz r式中: r为需要计算点年降水量的垂直递增率,单位为mm / m 。 |
| 9. | Note that while database maintenance and query operations are performed under the auspices of the rdbms , real - time performance for telemetry and calculated point update can only be achieved by supplementing the relational database with a distributed memory - resident , real - time subset 注意到数据库维护和查询操作是在关系数据库管理系统和遥测点及计算点的实时更新的支持下执行,这就只能通过增加具有分布式常驻内存的实时子集的关系型数据库来实现。 |
