[Introduction] In the coastal thermal power plant, the unit circulating cooling water system usually adopts the secondary circulation way, which needs to transfer water from the seaside to the front pool of the circulating pump house through the open water intake channel. An inverted trapezoidal section is generally used in the open water intake channel, while a rectangular section is generally used in the front pool of the circulating pump house. Therefore, the connection between the two requires an itd, which is connected from an inverted trapezoidal section to a rectangular section. [Method] In the engineering of the past, and flow in open channel water pump room link transition section of the former pool there are many kinds of forms, the most commonly used were divided into two kinds, one kind was through the connection of reinforced concrete box culvert, another was by reinforced concrete buttressed retaining wall connection, the former for wave conditions demand was not high, the latter for demanding wave conditions. [Result] Combined with the actual situation of the project site, a special curved surface transition scheme was innovatively proposed to connect the open water intake canal with the front pool of the pump house, and solve the connection difficulties and construction complexity of the transition section between the open water intake canal and the front pool of the pump house. This kind of special structure can not only give full play to the function of gravity retaining wall depending on backfilling soil and its own gravity resistance to sliding, but also reduce the occupied area and greatly reduce the project cost. [Conclusion] The engineering practice proves that this new type of curved surface transition section not only satisfies the actual use function of the site, but also saves the cost of the project and facilitates the construction.

Frequency Selective Surface (FSS) is a kind of spatial filter, it is widely used in many fields, such as radar and microwave communication, remote sensing and telemetry, and so on. However, design and fabrication of curved FSS for curved electromagnetic window is one of the bottlenecks for its engineering applications. To solve the problem of fabrication of curved frequency selective surfaces (FSS), a novel method of fabricating curved FSS based on threedimensional (3D) printing technique was developed. To testify the feasibility of this method, according to the shape of a radom of a missile, a curved FSS with undevelopable shape was designed and fabricated. First, FSS that adapted to large angle of incidence in the nose cone direction of the radome was designed, there was less than 200 MHz frequency drift with the range of 0° ~ 7 0° incident angle. Then, the 3D model of the curved FSS was created in UG and was digitalized, and the prototype of the curved FSS was fabricated by a 3D printer. Finally, a 10 microns thick aluminum film was coated on the outer surface of the curved FSS by a vacuum coater. The transmission performance of the curved FSS was tested using free space method. It showed that frequency selection characteristic of the curved FSS reached the design requirements. The passband was in the Ku-band and the transmission rate on center frequency was 63% for electromagnetic wave incident on nose cone direction. [ABSTRACT FROM AUTHOR]
