| 1 | Application of grey model on analyzing the passive natural circulation residual heat removal system of HTR-10显示文摘Using the grey correlation analysis,it can be concluded that the reactor pressure vessel wall temperature has the strongest effect on the passive residual heat removal system in HTR (High Temperature gas-cooled Reactor), the chimney height takes the second place,and the influence of inlet air temperature of the chimney is the least.This conclusion is the same as that analyzed by the traditional method.According to the grey model theory,the GM(1,1) and GM(1,3) model are built based on the inlet air temperature of chimney,pressure vessel temperature and the chimney height.Then the effect of three factors on the heat removal power is studied in this paper.The model plays an important role on data prediction,and is a new method for studying the heat removal power.The method can provide a new theoretical analysis to the passive residual heat removal system of HTR. | ZHOU Tao PENG Changhong WANG Zenghui WANG Ruosu | 2008 | Nuclear Science and Techniques2008，19，5： | 2 |

| 5 | Optimization and verification of wind tunnel free-flight similarity law for separation of cluster munition显示文摘In view of the separation form of the separator from the back of the carrier upward and from the side of the carrier outward, separation-safety research is carried out by taking the separation of a cluster munition as an example. In previous wind tunnel free-flight tests, the similarity law of vertical, downward, moving submunition was used to design submunitions at different positions in different initial-velocity directions, which resulted in large discrepancies between wind tunnel test results and real flight. In a wind tunnel test, each submunition has an independent time-reduction ratio with respect to the dispenser. Even if the separation trajectory of a single submunition is accurate, there will be errors in the position of each submunition at a given time. Therefore, it is necessary to determine the time-reduction ratio between submunitions, and to modify the test results later. In order to ensure the accuracy of wind tunnel test results, the similarity law of a freeflight test in a wind tunnel is derived in this paper. The time-correction scheme to ensure motion similarity between submunitions is solved. Numerical simulation is used to simulate the separation of a wind tunnel test and real aircraft, and the motion parameters of different submunitions are solved. The results show that the new similarity laws derived for different types of submunitions can greatly reduce the errors caused by previous similarity laws. In addition to the case for the separation of a cluster munition, the similarity law can also be applied to the free-flight test design of wind tunnels for vertical separation and horizontal separation of other kinds of aircraft. | Fei XUE Jun TANG Huaqiang WANG Zenghui JIANG Yuchao WANG Han QIN Peng BAI | 2021 | Chinese Journal of Aeronautics2021，34，3： | 1 |

| 8 | Metasurface-enabled polarization-independent LCoS spatial light modulator for 4K resolution and beyond显示文摘With the distinct advantages of high resolution,small pixel size,and multi-level pure phase modulation,liquid crystal on silicon(LCoS)devices afford precise and reconfigurable spatial light modulation that enables versatile applications ranging from micro-displays to optical communications.However,LCoS devices suffer from a long-standing problem of polarization-dependent response in that they only perform phase modulation on one linear polarization of light,and polarization-independent phase modulation-essential for most applications-have had to use complicated polarization-diversity optics.We propose and demonstrate,for the first time,an LCos device that directly achieves high-performance polarization-independent phase modulation at telecommunication wavelengths with 4K resolution and beyond by embedding a polarization-rotating metasurface between the LCoS backplane and the liquid crystal phase-modulating layer.We verify the device with a number of typical polarization-independent application functions including beam steering,holographical display,and in a key optical switching element-wavelength selective switch(WsS),demonstrating the significant benefits in terms of both configuration simplification and performance improvement. | Zhaoxiang Zhu Yuanhui Wen Jiagi Li Yujie Chen Zenghui Peng Jianxiong Liz Lei Zhu Yunfei Wu Lidan Zhou Lin Liu Liangjia Zong Siyuan Yu | 2023 | Light(Science & Applications)2023，12，7： | 0 |
