| 1 | Analytical algorithm for longitudinal deformation profile of a deep tunnel显示文摘To investigate the longitudinal deformation profile(LDP)of a deep tunnel in non-hydrostatic condition,an analytical model is proposed in our study.In this model,the problem is considered as a superposition of two partial models,and the displacement field of the second partial model is the same as that of the concerned problem.Therefore,the problem can be solved by a model with simple boundary conditions.We obtain the solutions for the stress and displacement fields of an infinite body caused by arbitrary surface tractions on the boundary of the coming tunnel(zone inside the tunnel before excavation)by integrating the extended Kelvin solution over the boundary.The obtained stress solution is used to solve the specific surface tractions,which can satisfy the boundary conditions of the second partial model,on the boundary of the coming tunnel in an infinite body.Then,the specific surface tractions are substituted into the obtained displacement solution to solve the displacement on the wall and face of the tunnel.Therefore,the LDP can also be calculated.The proposed solution is verified by both numerical simulation and the LDP functions recommended by other researchers.The major advantage of our analytical model is that it can consider the effects of the axial and horizontal lateral pressure coefficients.It is revealed that the horizontal lateral pressure coefficient majorly affects the LDP behind the tunnel face,while the axial lateral pressure coefficient dominates the LDP ahead of the tunnel face.Furthermore,the deformation characteristics of the LDPs ahead of the face and the unexcavated core are investigated.The axial displacements of the excavation face can be used to predict the crown displacements ahead of the face. | Qian Fang Gan Wang Fucai Yu Jianming Du | 2021 | Journal of Rock Mechanics and Geotechnical Engineering2021，13，4： | 2 |

| 4 | Modelica-based Object-orient Modeling of Rotor System with Multi-Faults显示文摘Modelica-based object-orient method is proved to be rapid,accurate and easy to modify,which is suitable for prototype modeling and simulation of rotor system,whose parameters need to be modified frequently.Classical non-object-orient method appears to be inefficient because the code is difficult to modify and reuse.An adequate library for object-orient modeling of rotor system with multi-faults is established,a comparison with non-object-orient method on Jeffcott rotor system and a case study on turbo expander with multi-faults are implemented.The relative tolerance between object-orient method and non-object-orient is less than 0.03%,which proves that these two methods are as accurate as each other.Object-orient modeling and simulation is implemented on turbo expander with crack,rub-impact,pedestal looseness and multi-faults simultaneously.It can be conclude from the case study that when acting on compress side of turbo expander separately,expand wheel is not influenced greatly by crack fault,the existence of rub-impact fault forces expand wheel into quasi-periodic motion and the orbit of expand wheel is deformed and enhanced almost 1.5 times due to pedestal looseness.When acting simultaneously,multi-faults cannot be totally decomposed but can be diagnosed from the feature of vibration.Object-orient method can enhance the efficiency of modeling and simulation of rotor system with multi-faults,which provides an efficient method on prototype modeling and simulation. | LI Ming WANG Yu LI Fucai LI Hongguang MENG Guang | 2013 | Chinese Journal of Mechanical Engineering2013，26，6： | 1 |

| 7 | Research Progress of Metal-Based Shielding Materials for Neutron and Gamma Rays显示文摘The radiation generated by nuclear reaction is harmful to human body and equipment,thus the radiation shielding materials that employ the shielding ability from neutron and gamma rays are the best candidates according to application situations and radiation sources.In this paper,the researches of metal-based neutron and gamma rays or multiple purpose shielding materials are systematically summarized,and the respective and principal problems of these materials with respect to shielding effectiveness and other performances,such as corrosion,mechanical properties,manufacture,etc.,are discussed.Finally,the prospect of shielding materials is outlined,which suggests that the development of highly efficient and multiply functional radiation shielding materials with good environmental compatibility is one of the future development trends. | Bin Gan Shichang Liu Zhen He Fucai Chen Haoxuan Niu Jingchang Cheng Bo Tan Bo Yu | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，12： | 1 |
| 8 | Pyramiding of multiple genes generates rapeseed introgression lines with clubroot and herbicide resistance, high oleic acid content, and early maturity显示文摘Clubroot and herbicide resistance,high oleic acid(OA)content,and early maturity are targets of rapeseed(Brassica napus L.)breeding.The objective of this study was to develop new male-fertility restorer lines by pyramiding favorable genes to improve these traits simultaneously.Seven elite alleles for the four traits were introduced into the restorer line 621R by speed breeding with marker-assisted and phenotypic selection.Six introgression lines(ILs)were developed with four-to seven-gene combinations and crossed with two elite parents to develop hybrids.All ILs and their corresponding hybrids displayed high resistance to both clubroot pathotype 4 and sulfonylurea herbicides.Three ILs and their hybrids showed large increases in OA contents and four showed earlier maturity.These new ILs may be useful in rapeseed hybrid breeding for the target traits. | Zhaoyang Wang Fucai Wang Zihan Yu Xiaorui Shi Xianming Zhou Pengfei Wang Yixian Song Dengfeng Hong Guangsheng Yang | 2023 | The Crop Journal2023，11，3： | 0 |
| 9 | The stimulation on shedding reactions of sea urchins by K^+ and Li^+ immersion显示文摘INTRODUCTION Sea urchin is a marine animal of economic value. The gonad of Hemicentrotus pulcherrimus A. Agassiz and Anthocidaris crassispina A. Agassiz may be offered as food and medicine, the sea urchin shell may be used as fertilizer and artware and moreover, the sea urchin eggs are important materials for the studies in embryology and molecular biology. With the increasing exportation of sea urchins in China, the natural resources are gradually decreasing.
