Typically, online aggregation algorithms on multi-dimensional data need additional auxiliary data for estimation, which make the performance of the storage and maintenance of the data cube worse.

以往在数据立方体上实现的联机聚集往往需要附加空间来存储联机聚集估算所需要的信息，极大地影响了数据立方体的存储和维护性能。

Although the Preissman scheme of KP equation is multisymplectic, it took too efforts to realize, Hence we elimate the auxiliary variable by a trivial computation and obtained the multisymplectic forty-five points scheme of KP equation. And then, we test this forty-five points scheme on soliton and solitary waves over long time intervals, the numerical results shows the propagation and interact of soliton and solitary waves.

但是在实际的数值实验中，由于需要计算共轭动量的值，Preissman格式需要占用的计算内存比较大，计算时间比较长，因此我们在数值格式中消去共轭动量，最后得到与多辛Preissman格式等价的一个多辛45点格式，我们用这个格式进行了数值实验，数值实验结果很好地显示了孤立子和孤立波的传播与碰撞。

Based on the results of the study, suggestions are presented as follows:(1) Some of the old people who did not think to take a health examination. It is suggested that involved organizations ought to explore the real reasons of their averseness by conducting more investigations to make these services well.

根据研究结果提出以下之建议：许多未做健康检查的老年人因为不觉得自己需要做健康检查而未做，因此建议相关单位应透过更多的调查研究或深入社区去发掘不觉得需要健康检查的真正原因，以使这些服务达到最大效用。
