| 1 | 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 |
| 2 | Spraying printing of liquid metal electronics on various clothes to compose wearable functional device显示文摘Liquid metal printing is emerging as an important tool for making wearable electronics. However, very limited academic efforts were made to fulfill such an increasing need. This paper is dedicated to present relatively complete theoretical and experimental characterizations for liquid metal spraying printing towards developing wearable electronic textile. The practical conditions of liquid metal droplets in the spraying printing process such as the jet velocity, the size distribution of droplets and their evenness degree, the morphology of droplets and their unrolling areas after impacting the substrate are quantified. The dominating factors, including the oxidation of liquid metal and the pressure force on cloth substrate during the impacting process, which ensure liquid metal firmly adhere to the cloth, are clarified. Further, various clothes are comparatively investigated to test their capabilities in printing liquid metal conductors, where the resistance difference can be over thousand-fold. In addition to interpreting the basic mechanisms and performances of the spraying printing, two programmable flexible circuits with specifically designed functions such as blinking LED lighting and wireless infrared temperature measurement via current manufacture technology were also demonstrated and evaluated for their washable ability. With the realization of wearable modules via liquid metal printing technology, it can be expected that flexible functional devices on cloth fabricated quickly and directly would witness more broad applications in the coming time. | GUI Han TAN SiCong WANG Qian YU Yang LIU FuJun LIN Ju LIU Jing | 2017 | Science China(Technological Sciences)2017，60，2： | 8 |
| 3 | Design and simulation of an innovative cylinder fabricated by selective laser melting显示文摘Additive Manufacturing(AM) processing has attracted wide attention due to its advantages, e.g., rapid prototyping and free design. In aeronautic and astronautic engineering, it is especially attractive to apply AM processing, especially Selective Laser Melting(SLM), into primary structures that always occupy most of the whole mass of aircraft or spacecraft. In this paper, an innovative lattice sandwich structure that is suitable to be manufactured with SLM is adopted to design the typical cylinder under axial compression. Firstly, the mechanical properties of pyramidal lattice are investigated, and the bearing capacity of the lattice sandwich cylinder is given analytically for each failure mode. Secondly, a composite cylinder is re-designed in the form of lattice sandwich structure, which sizes are ultimately obtained through optimization. Finally, finite element model of the innovative cylinder is established and several kinds of imperfection are introduced to simulate the defects caused by SLM. Numerical result shows that the lattice sandwich design can obviously enhance the bearing capacity of cylindrical shell even though the original one is designed with composite material. In other words, SLM has great potential in improving the primary structure of spacecraft in the future. | Guang MENG Bin JI Han HAN Chengzhang GU Renbang LIN Fujun PENG | 2019 | Chinese Journal of Aeronautics2019，32，1： | 7 |
| 4 | 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 | Fossil Liverworts from the Lower Cretaceous Huolinhe Formation in Inner Mongolia, China显示文摘A new genus and species, Rebouliothallus huolinhensis sp. nov., and two uncertain species, Ricciopsis sp. and Hepaticites sp., are described. The fossils were collected from the Lower Cretaceous Huolinhe Formation of Huolinhe Basin, northeastern China. The new genus Rebouliothallus was established in the Aytoniaceae family of Marchantiales. Rebouliothallus huolinhensis appears to be quite similar to species of the extant genus Reboulia Raddi. The species is characterized by the relatively large ventral scales. Ventral scales are large, imbricate and arranged in two rows on the ventral surface. Rhizoids are either pegged or smooth. Ricciopsis sp. is characterized by the rosetteforming thallus. Hepaticites sp. shows some similarities to liverworts. Of the forty-nine Early Cretaceous floras of China, only two floras, one from the Huolinhe basin, Inner Mongolia and the other from the Jixi Basin, Heilongjiang Province, contain fossil liverworts. The rare fossil liverwort records in the Early Cretaceous floras of China may be the result of taphonomic bias. | LI Ruiyun WANG Xuelian JIN Peihong MA Fujun YAN Defei LIN Zhicheng SUN Bainian | 2016 | Acta Geologica Sinica(English Edition)2016，90，3： | 2 |

| 8 | 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 |
