The outstanding functions of this multi-fucntional wheelchair is that the hight of the seat could be adjusted at will. So that it may stretch users' operating space and make up users' physical handicap.It could alleviate the workload of paramedics as well. It is more advanced than previous products.This wheelchair could be driven by hand or electricity. Thus, the shortage of physical force of old and handicapped people could be solved. At the same time, users could still operate this wheelchair when batteries run out. Such design eliminate worries of users on a long-distance trip.In addition, a super big storage box on tail of wheelchair brings great convenience to users. backrest can be adjusted multi-anglely. Adjusted feet board increases cosiness. A small table of this wheelchair really brings extraordinary convenience when users want to read, write or do other activities.

本设计的多功能轮椅最突出的一个功能就是座位的高度可以根据使用者的需求随意进行调节，这样就可以大大扩展使用者的操作空间，补充了使用者在身体上的缺陷，也可以减轻照顾人员的工作负担，比起以前的产品有了较明显的改进；其他功能还有轮椅的手动电动两种驱动方式，这样可以解决老年人和残疾人在体力上存在的问题，同时在外出时遇上没电的情况也不至于显得无能无力，消除了使使用者在长途奔波时的顾虑；此外位于轮椅尾部的超大储物筐，给使用者携带物品带来了极大的方便，靠背的多角度调节，脚踏板的高度调节大大增加了使用者的使用舒适度，轮椅上小桌的设计给使用者读书，写字，进行其他活动带来了极大的方便。

The comprehensive treatment project of Tong Ken landslide consists of whittling slope、anti-landslide pile with anchoring cable、retaining wall、building ground drainages leveling off and calking slope、vegetation protection etc. After managing, under the action of earthquake load and watery the stability coefficient of landslide is up to 1.10.Then, this text researches the structural optimization design of anti-slide pile with anchoring cable. On the condition that the width of section is invariable, the height of section is confirmed by structural optimization method. This will change traditional method to optimize the height of section so that design is simplified and cost is lower.

These results show that:(1) the results retrieved from the Abel integral and absolute TEC inversion are consistent on the whole at higher orbits altitude (~800 km), and in good agreement with those measured by ionosondes; the results retrieved from absolute TEC inversion are in better agreement with those obtained from ionosondes than that by the Abel integral inversion at lower orbits attitude (~500 km);(2) the maximal electron density N m from absolute TEC inversion is closer to N mF2 from ionosondes than that from Abel integral inversion, and the method of the former is more rigorous and effective than that of the latter;(3) absolute TEC is more sensitive to cycle slip than Abel integral, but for the two ways significant loss of inversion precision due to cycle slip always exists.

结果表明：（1）在较高轨道高度（约800 km），Abel积分与绝对TEC方法的反演结果基本一致，都与电离层测高仪反演结果符合良好；在较低轨道高度（约500 km），绝对TEC反演精度优于Abel积分反演精度；（2）绝对TEC反演的最大电子密度 N m较Abel积分法获得的结果更接近于电离层测高获得的峰值电子密度 N mF2，绝对TEC反演法更加严密和有效；（3）周跳对绝对TEC反演结果的影响较Abel积分反演结果的影响更为敏感，但无论哪种方法，周跳对反演精度都造成严重损失。
