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。

Under the leadership of the Communist Party of China and the guidance of Marxism-Leninism, Mao Zedong Thought and Deng Xiaoping Theory, the Chinese people of all nationalities will continue to adhere to the people's democratic dictatorship and the socialist road, persevere in reform and opening to the outside world, steadily improve socialist institutions, develop the socialist market economy, develop socialist democracy, improve the socialist legal system and work hard and self- reliantly to modernize the country's industry, agriculture, national defense and science and technology step by step to turn China into a socialist country that is prosperous, powerful, democratic and culturally advanced.

中国各族人民将继续在中国共产党领导下，在马克思列宁主义、毛泽东思想、邓小平理论指引下，坚持人民民主专政，坚持社会主义道路，坚持改革开放，不断完善社会主义的各项制度，发展社会主义市场经济，发展社会主义民主，健全社会主义法制，自力更生，艰苦奋斗，逐步实现工业、农业、国防和科学技术的现代化，把我国建设成为富强、民主、文明的社会主义国家。

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。

This thesis studied three different kinds of hydrolytic condensation methods of Me_3SiCl and MeSiHCl_2: co-hydrolytic condensation reaction, step-by-step hydrolytic condensation reaction and reversive hydrolytic condensation reaction, and analysized the hydrolytic condensation mechanism of chlorosilane.

Of hypertension, heart disease, mouth sores, a calcium deficiency disease, scurvy, such as a certain degree of efficacy, as people eat lemons, usage, and uses step-by-step know, lemon market capacity will be more and more large, lemon is a perennial small evergreen tree, which is Rutaceae, Citrus.

对高血压、心脏病、口舌生疮、缺钙症、坏血病等一定的疗效，随着人们对柠檬吃法、用法及用途的逐步了解，柠檬市场容量将越来越大、柠檬是一种多年生常绿小乔木，属芸香科，柑桔类。

The results show that the SAPO–5 has a pillar-like morphology with the size of about 20 μm×5 μm×5 μm.The ratio of P:Al:Si is 1:1.19:0.67 in its crystal structure, the content of Si is high. The total acidimety fo the SAPO–5 is 578.0 μmol/g , hihger than that of prepared by one step crystalline hydrothermal method.And its initial catalysis character performance on normal butane isomerization reaction reach 24.8 %, higher than that of prepared by one step crystalline hydrothermal method.

实验结果表明：产物为柱状的磷酸硅铝分子筛，其晶粒尺寸大约为20 μm×5 μm×5 μm，其晶体结构中P：Al：Si＝1：1.19：0.67，硅含量较高；采用分段晶化方式制备的SAPO-5分子筛的总酸量为578.0 μmol/g高于一段晶化方式制备的SAPO-5分子筛的总酸量；采用分段晶化生成的SAPO-5分子筛的催化正丁烷异构化反应初始活性可达到24.8 %，远高于一段晶化制备的SAPO-5分子筛的初始活性14.1 %。

Sodium lauroyl sarcosine was used as a denaturant, a novel protein refolding method, which was proposed on the basis of one step-AMC and IEC, one step-AMC-IEC was used on the refolding of denatured/reduced lysozyme.

一步人工分子伴侣-离子交换色谱法辅助还原变性溶菌酶的复性：以月桂酰基肌氨酸钠(Sodium Lauroyl Sarcosine，Sarkosyl，SLS)作为蛋白变性剂，发展了一步人工分子伴侣-离子交换色谱法，对还原变性溶菌酶进行了复性研究。

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

塑宝SV泵剖面结构SV Super Series Analytical cross section SV泵剖面结构泵开始运转时，底部叶轮将液体逐步上推，待液体进入上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。
