| 1 | Long-term thermal regimes of the Qinghai-Tibet Railway embankments in plateau permafrost regions显示文摘Ten years of ground temperature data(2003–2013) indicate that the long-term thermal regimes within embankments of the Qinghai-Tibet Railway(QTR) vary significantly with different embankment structures. Obvious asymmetries exist in the ground temperature fields within the traditional embankment(TE) and the crushed-rock basement embankment(CRBE). Measurements indicate that the TE and CRBE are not conducive to maintaining thermal stability. In contrast, the ground temperature fields of both the crushed-rock sloped embankment(CRSE) and the U-shaped crushed-rock embankment(UCRE) were symmetrical. However, the UCRE gave better thermal stability than the CRSE because slow warming of deep permafrost was observed under the CRSE. Therefore, the UCRE has the best long-term effect of decreasing ground temperature and improving the symmetry of the temperature field. More generally, it is concluded that construction using the cooling-roadbed principle meets the design requirements for long-term stability of the railway and for train transport speeds of 100 km h?1. However, temperature differences between the two shoulders, which exist in all embankments shoulders, may cause potential uneven settlement and might require maintenance. | NIU Fu un LIU MingHao CHENG GuoDong LIN ZhanJu LUO Jing YIN GuoAn | 2015 | Science China Earth Sciences2015，58，9： | 14 |
| 2 | Acoustic experimental study of two types of rock from the Tibetan Plateau under the condition of freeze-thaw cycles显示文摘Under the condition of freeze-thaw cycles,two types of rocks(granite and andesite),used as slope protection for the Qinghai-Tibet Railway,were tested according to the special climatic conditions in the Tibetan Plateau,and their various damage processes in appearance were carefully observed.Observation results show that damage of andesite was more serious than that of granite.Using an acoustic instrument,ultrasonic velocity was tested.The changing trends of velocity with the number of freeze-thaw cycles were analyzed,and the freeze-thaw cycle damaging the physical and mechanical properties of rocks can be seen.According to the changing trends of ultrasonic velocity with the number of freeze-thaw cycles,mechanical parameters of rocks,such as dynamic elasticity modulus,Poisson's ratio,and dynamic bulk modulus were analyzed.It is found that they all have declining trends as the number of freeze-thaw cycles increases,and in particular,when the cycle number reaches a certain extent,the Poisson's ratio of rocks begins to become negative. | Hua Liu FuJun Niu ZhiYing Xu ZhanJu Lin Jian Xu | 2012 | Research in Cold and Arid Regions2012，4，1： | 10 |
| 3 | Study of stimulated Raman and Brillouin scattering in a finite interaction region under the convective instability condition显示文摘We discuss stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS) under the convective instability condition with a one-dimensional three-wave interaction (3WI) model.Using linear theory,we deduce the temporal growth rate,gain exponent,and reflectivity of the backward scattered wave in a finite interaction region.We find that the growth rate is not only determined by the laser intensity and plasma density and temperature,but also related to the spatial gain.The length of the interaction region is important to the gain exponent and backscattering level.We simulate the developments and evolutions of SRS and SBS based on the 3WI equations.Our numerical results consist with the linear theory. | HAO Liang LIU ZhanJu ZHENG ChunYang XIANG Jiang FENG Wu HU XiaoYan LI Bin | 2012 | Chinese Science Bulletin2012，57，21： | 5 |
| 4 | Dichotomous roles of neutrophils in modulating pathogenic and repair processes of inflammatory bowel diseases显示文摘Neutrophils are considered as complex innate immune cells and play a critical role in maintaining intestinal mucosal homeostasis.They exert robust pro-inflammatory effects and recruit other immune cells in the acute phase of pathogen infection and intestinal inflammation,but paradoxically,they also limit exogenousmicrobial invasion and facilitate mucosal restoration.Hyperactivation or dysfunction of neutrophils results in abnormal immune responses,leading to multiple autoimmune and inflammatory diseases including systemic lupus erythematosus,rheumatoid arthritis,and inflammatory bowel diseases(IBD).As a refractory intestinal inflammatory disease,the pathogenesis and progression of IBD are associated with complicated immune response processes in which neutrophils are profoundly involved.However,the consensus on potential roles of neutrophils in modulating pathogenic and repair processes of IBD remains not fully understood.Accumulated infiltrating neutrophils cross the epithelial barrier and contribute to microbial dysbiosis,aggravated intestinal architectural damage,compromised resolution of intestinal inflammation and increased risk of thrombosis during IBD.Paradoxically,activated neutrophils are also associated with effective elimination of invaded microbiota,promoted angiogenesis and tissue restoration of gutmucosa in IBD.Here,we discuss the beneficial and detrimental roles of neutrophils in the onset and resolution of intestinalmucosal inflammation,hoping to provide a precise overview of neutrophil functions in the pathogenesis of IBD. | Huimin Chen Xiaohan Wu Chunjin Xu Jian Lin Zhanju Liu | 2021 | Precision Clinical Medicine2021，4，4： | 3 |
| 5 | In-situ testing study on convection and temperature characteristics of a new crushed-rock slope embankment design in a permafrost region显示文摘For the purpose of enhancing air convection and controlling solar radiation, a new crushed-rock slope embankment design combined with a sun-shade measure is proposed. A newly designed embankment was constructed in the Tuotuohe section of the Qinghai-Tibet Railway and a field-testing experiment was carried out to determine its convection and temperature characteristics. The results show that distinct air convection occurred in the crushed-rock layer of the new embankment, especially in cold seasons, which was enhanced when it flowed upwards along the slope. This preliminarily indicated that the new design of the embankment slope was good for reinforcing air convection in the crushed-rock layer. The frequent fluctuations of the convection speed and the environmental wind speed were in good agreement, suggesting that the convection in the crushed rock primarily came from the ambient wind. It was also preliminarily determined that the new embankment had a better cooling effect and sun-shade effect for decreasing the temperature of the embankment slope compared with a traditional crushed-rock slope embankment, and the mean temperature difference between them was up to 1.7 °C. The mean annual temperature at the bottom boundary of the crushed-rock layer was obviously lower than that at the top boundary, and heat flux calculation showed that the shallow soil beneath the embankment slope was weakly releasing heat, all of which indicated that the new embankment slope design was beneficial to the thermal stability of the embankment. This study is helpful in providing some references for improved engineering design and maintenance of roadbeds in permafrost regions. | MingHao Liu FuJun Niu JianHong Fang ZhanJu Lin Jing Luo GuoAn Yin | 2014 | Research in Cold and Arid Regions2014，6，4： | 3 |
| 6 | Dating of two thermokarst lakes in Beiluhe Basin, Qinghai-Tibetan Plateau显示文摘Most of the thermokarst lakes are spread appreciably in Beiluhe Basin,Qinghai-Tibet Plateau,China,where ice-rich permafrost exists.Two typical thermokarst lakes with differing area and depth were examined to ascertain their age.We obtained lake-bottom samples of 50 cm length from lake BLH-A and 25 cm length from lake BLH-B.Environmental 137 Cs and 210 Pb and radiocarbon age dating techniques were applied to the 50 cm and 25 cm samples,respectively.The results indicate that the initiation of BLH-A is about 800–900 a B.P.,and approximately 1,450±30 a B.P.to 2,230±30 a B.P.for BLH-B.These results will provide scientific bases for sedimentological study and thermokarst activity in Beiluhe Basin. | ZhanJu Lin FuJun Niu Jing Luo MingHao Liu GuoAn Yin | 2014 | Research in Cold and Arid Regions2014，6，5： | 1 |
