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。

The ratios of k~1 and k~2 varied within the range of 4.24～133, which showed that the control step for oxidation of CO over REFeO~3 was the reoxidation step of reduced catalyst.

催化剂用CO还原的速率常数k~1比还原了的催化化剂用O~2再氧化速率常数k~2要大， k~1/k~2值在4.22～133之间，这说明在REFeO~3上CO氧化的控制步骤为还原催化剂的再氧化。

Obviously, if it's a critical step, than the expectation is that it would have been validated initially, and if you repeat in the reprocess a critical step, there's really no expectation to revalidate it because it's already been validated.

很显然，如果是关键步骤，我们会要求在一开始就验证了，如果你重复的返工步骤是关键步骤，那么没有必要再验证它因为你已经验证过了。
