The use of unbonded tendons is now common in prestressed concrete structures, and they may be in the form of internal or external tendons.With the increasing use of unbonded tendons in both new construction and retrofitting of existing structures, there is the need for a closer look at their design and analysis.

采用无粘结预应力是现在常见的预应力钢筋混凝土结构，并且它们可能采取的形式是内部或外部tendons.with越来越多地使用无粘结预应力在这两个新的建设和改造现有的结构，有必要建立更密切看看他们的设计与分析。

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先，钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能，并且有明显的协同作用，从而能抑制部分点蚀核的产生；其次，钼酸盐复配缓蚀剂的使用，从电化学的角度分析，具有明显的钝化性能，且钝化区间较宽、维钝电流密度较小，从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化，得到有效的修复；最后，对于还有部分蚀孔发展成为闭塞腐蚀电池的情况，钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐，从而有效地减缓了点蚀的恶化，抑制了腐蚀的发展。

The results indicate: diversion shell can transform the kinetic energy of fluid into pressure energy well, and eliminate the circumferential component of fluid; the inlet incidence angle of vaned diffuser increases at the condition of O.8Q, and it results in flow separation very likely and the hydraulic loss increases; it is nearly non-impact inflow at the condition of 1.2Q, and the velocity distribution is uniform at the inlet of vaned diffuser and flow separation dose not appear.

结果表明：导流壳能很好地将叶轮中流出的流体的动能转化为压能，并消除速度的圆周分量；在0.8Q工况下，空间导叶的进口冲角增大，容易在空间导叶背面产生流动分离，造成水力损失增加；在1.2Q工况下，空间导叶的进口接近无冲击入流，在进口处流速分布较均匀，其内部未发生流动分离现象。

The auther adopted virginly the technique of the 3DPIV at home, and acquired the reliable measurement data, which assumes the important realistic signification for revealing the essence of the flowing in the pump sump, verifying the mathematical model of the CFD computation and boundary conditions, and optimizing the hydraulic design of the pump sump.

In the process of different people accepting creation education, the characteristics in psychological process and personality's difference are always being neglected the component obstacle is baffling the creation education, education system inner part in narrow sense, analyze the teaching barriers of the creation education in teaching the current course structure exists some problem in itself constructive factor the current course contents escapes from the source of creation education namely the student's living world, the course implement process emphasizes to accept study and memorize or train mechanically, seldom let the student obtain the knowledge through his own activities and practice, the student rarely have the opportunity to express his viewpoint and opinion through his own understanding, this annihilates the student' personality and corpus such instruction process is nearly making the student under control according to the craft process, The student can't creatively express himself, so it constitute the obsatacle of creation education.

社会本位观突出了要求个体奉献社会的一面，忽视了个体突破已有社会秩序与常规的富有建设意义的独创思想与行为对社会发展的价值；同时从心理学的视角，对创造教育的心理障碍进行了剖析，不同的个体在接受创造教育的过程中，心理过程的特点与个性差异的被忽视，构成的障碍阻碍着创造教育；在狭义的教育系统内部，就创造教育的课程教学障碍进行了分析，当前的课程结构在其构成要素上本身存在一些问题；现行课程内容脱离创造教育之源，即学生的生活世界；课程实施过程存在过于强调接受学习、死记硬背、机械训练的现状，很少让学生通过自己的活动与实践获取知识，学生少有根据自己的理解发表看法与意见的机会，这是对学生个性的抹杀，这样的教学过程几乎是根据工艺流程对学生进行控制的过程，学生无法创造性地表现自己，对创造教育构成了障碍。

First, the paper analyzes 217 factory"s exterior environments completely and objectively by the models of PEST and Boter "s "five forces" and it points out the opportunities and the challenges for 217; Second, making use of the strategic groups theories, the BOSTON matrix analysis, the core ability theories and value chains theories, the paper analyzes the competition position of 217 factory in AC profession. It explicates the main rivals of 217 and the present conditions that 217 factory makes use of chances and averts the exterior threat; The third, according to the exterior environment and internal resources-ability of analysis, the paper makes use of the theories of SWOT to map out competition strategic projects.
