The mean Harris score was 47.3 preoperatively and 83.2 postoperatively. The excellent and good rate was 90.1%. The position of prosthesis was appropriate, no loosening or sinking was found at the final follow-up evaluation. Radiotransparent region was found in one region of one case three months after surgery but with no sclerosis, rest pain or activity pain, fever, or local swelling.

Harris评分由置换前的平均47.3分上升到置换后的83.2分，优良率90.1%，最近一次随访X射线片评价假体在位良好，无松动、下沉现象，关节功能恢复情况满意。1例翻修患者于髋关节置换后3个月复查时发现1区有局限性透光带，无明显硬化带，患者无静息痛或活动疼痛，无全身发热、局部红肿表现，为骨长入性稳定。

After flow and transient stability calculating of the 330kV grid, we got the over-load and hazard lines set. Then we gained the redundant network needed to be built according to the increasing power supply and load in 2010. Adopting regradation step-by-step algorithm by which we can improve the calculation efficiency , we compared the validity of every line, deleted lines with low validity until no redundant line is in the network. At last we got the target network framework adopting the improved ant colony algorithm. Flow distribution, construction investment assessment and target framework of Gansu long-term planning all be considered, from the viewpoint of to be economic and reliability the feasibility of the improved ant colony algorithm is discussed.

在对2006年该网架结构进行了潮流计算与暂态稳定计算分析后，得出了系统的过负荷与危险线路集，并针对2010年新增的电源和负荷点确定了冗余的待建网架，然后利用逐步倒推法比较各待选线路在系统中的有效性，逐步去除有效性低的线路，直到网络中没有冗余线路为止，以此来以提高优化算法的计算效率，最后利用改进后的蚁群算法确定优化后的目标网架结构，并从潮流分布、建设投资估算等方面与甘肃电网远期规划中确定的目标网架进行了比较，从可靠性和经济性角度论证了改进蚁群算法在网架优化中的可行性。

Although rare, another potential complication that can occur is the development of a sternal infection due to a significant decrease of sternal blood supply in the retrosternal area when harvesting the internal thoracic vessels.27

虽然罕见，另一个潜在的并发症是胸骨感染，由于分离出胸廓内动脉后显著减低了胸骨后的血供。
