Subsequently, through the dynamic mechanisms of investment, the endogenesis of price, consideration of the resource constraints and the alternativity between productive factors, this paper completed the historic simulation to update key data, then built the closure criteria for baseline simulation, combined the dynamic recursive methord, finally assessed the long-term impact for member states in terms of policy changes under 4 scenarios. Different to the analysis from perspective of comparative static, the assessment of long-term economic impact was started from the macroeconomic point of view and import and export trade to reflect the relationship between short-term influence and long-term impact under 4 kinds of possible policy changes.

首先从CGE模型传统的比较静态的框架下，就GDP、贸易规模、双边贸易、贸易结构及产出水平、国民福利等方面来阐释各政策情景产生的冲击效果；然后通过投资动态机制与价格的内生化，考虑资源限制及生产要素间的替代性，以逐年递归动态求解方式，分国别从宏观经济、进出口贸易角度出发，对于成员国在政策变动后可能产生的远期影响进一步做出评估，以此来反映各种可能的政策变动对成员国经济的短期影响与长期影响之间的关系。

Drought caused photoinhibition and increased the damage of reactive oxygen. Antioxygenation of fast-growing 107 was stronger than Populus pseudo-simonii.2. As expected, both NO and ABA can induce stomatal closure of detached populus leaves.

107杨具有较强的抗氧化能力，干旱诱导酶活性提高；小青杨抗氧化能力较弱，造成活性氧积累，导致光氧化伤害。

A method using planar antipodal grasp theorem and another theorem from it proposed by Ebert-Uphoff to determine the boundary of force closure workspace for wire-driven parallel manipulators with 1R2T class with 2-2 type has been demonstrated.

利用平面对心抓取定理与Ebert-Uphoff提出的相关定理，确定2-2型1R2T机构的力封闭工作空间边界。

Initially, the approach involved a simple ring closure, but this technique failed because the deeper aponeurotic tissues could not be approximated without tension in the repair. The plug-and-patch technique also failed to match the results of its open counterpart.

最早的术式为单纯环状缝合闭合术，但是存在深腱膜组织有一定张力的缺点；其次是堵塞和贴补术式，同样由于缺乏与开放式手术的竞争能力而宣告失败。

Methods:Select 11～18 year old patients with bimaxillary protrusion 20 cases were randomly divided into two groups:TPA group,TPA＋Nance arch group.Two cases are the uprooting of four first premolars,the use of straight wire appliance technology,one step closure extraction gap analysis before and after treatment lateral skull X ray film and dental cast changes in the indicators.

Results The long term results of the vascularized fibular graft varied in different types of bone defects. Nine patients with congenital pseudoarthrosis of tibia had the limb function restored in 65％ and one had nonunion of fibular graft, 3 fractures(7 times), and 5 angular deformities. Three patients with congenital radial deficiency had 62％ restoration of the limb function. All of them showed early closure of epiphyses of the grafted fibulae. Five cases with osteomyelitis and bone defects combined soft tissue deficiency had 94％ restoration of the limb function, and only one occurred fracture of fibular graft. One case with soft tissue defect and concomitant ulnar defect, ulnar nerve and median nerve injury, 67％ function of limb was recovered, and union of fibula graft was good. 100％ function of limb was recovered in 1 case with cavernoma of radius and without occurring valgus deformity of donor site.

结果应用带血管腓骨移植修复骨缺损的远期效果因缺损类型的不同而存在较大差异。9例先天性胫骨假关节患者，术后肢体功能恢复65％，其中移植腓骨骨不连1例、骨折3例(7次)、成角畸形5例；3例先天性桡骨缺如患者，术后肢体功能恢复62％，3例术后均出现移植腓骨骨骺线早闭，畸形复发；5例骨髓炎、骨外露、骨缺损并软组织缺损患者，术后肢体功能恢复94％，仅1例发生移植腓骨骨折；1例前臂软组织缺损并尺骨缺损，尺神经、正中神经损伤者，术后肢体功能恢复67％，骨愈合顺利；1例桡骨海绵状血管瘤者，术后肢体功能恢复100％，骨愈合顺利。
