| 1 | Soil erosion and sediment interception by check dams in a watershed for an extreme rainstorm on the Loess Plateau,China显示文摘The magnitude of soil erosion and sediment load reduction efficiency of check dams under extreme rainstorms is a long-standing concern.The current paper aims to use check dams to deduce the amount of soil erosion under extreme rainstorms in a watershed and to identify the difference in sediment interception efficiency of different types of check dams.Based on the sediment deposition at 12 check dams with 100% sediment interception efficiency and sub-catchment clustering by taking 12 damcontrolled catchments as clustering criteria,the amount of soil erosion resulting from an extreme rainstorm event on July 26,2017(named '7·26' extreme rainstorm) was estimated in the Chabagou watershed in the hill and gully region of the Loess Plateau.The differences in the sediment interception efficiency among the check dams in the watershed were analyzed according to field observations at 17 check dams.The results show that the average erosion intensity under the '7-26' extreme rainstorm was approximately 2.03×10~4 t/km^2,which was 5 times that in the second largest erosive rainfall in 2017(4.15×10~3 t/km^2) and 11-384 times that for storms in 2018(0.53×10~2 t/km^2-1.81×10~3 t/km^2).Under the '7-26' extreme rainstorm,the amount of soil erosion in the Chabagou watershed above the Caoping hydrological station was 4.20 × 106 t.The sediment interception efficiency of the check dams with drainage canals(including the destroyed check dams) and with drainage culverts was 6.48 and 39.49%,respectively.The total actual sediment amount trapped by the check dams was 1.11 × 106 t,accounting for 26.36% of the total amount of soil erosion.In contrast,3.09×106 t of sediment were input to the downstream channel,and the sediment deposition in the channel was 2.23×10~6 t,accounting for 53.15%of the total amount of soil erosion.The amount of sediment transport at the hydrological station was8.60×10~5 t.The Sediment Delivery Ratio(SDR) under the '7·26' extreme rainstorm was 0.21.The results indicated that the amount of soil erosion was huge,and the sediment interception efficiency of the check dams was greatly reduced under extreme rainstorms.It is necessary to strengthen the management and construction technology standards of check dams to improve the sediment interception efficiency and flood safety in the watershed. | Leichao Bai Nan Wang Juying Jiao Yixian Chen Bingzhe Tang Haolin Wang Yulan Chen Xiqin Yan Zhijie Wang | 2020 | International Journal of Sediment Research2020，35，4： | 7 |
| 2 | Diamond Raman laser:a promising high-beam-quality and low-thermal-effect laser显示文摘Stimulated Raman-scattering-based lasers provide an effective way to achieve wavelength conversion.However,thermally induced beam degradation is a notorious obstacle to power scaling and it also limits the applicable range where high output beam quality is needed.Considerable research efforts have been devoted to developing Raman materials,with diamond being a promising candidate to acquire wavelength-versatile,high-power,and high-quality output beam owing to its excellent thermal properties,high Raman gain coefficient,and wide transmission range.The diamond Raman resonator is usually designed as an external-cavity pumped structure,which can easily eliminate the negative thermal effects of intracavity laser crystals.Diamond Raman converters also provide an approach to improve the beam quality owing to the Raman cleanup effect.This review outlines the research status of diamond Raman lasers,including beam quality optimization,Raman conversion,thermal effects,and prospects for future development directions. | Yulan Li Jie Ding Zhenxu Bai Xuezong Yang Yuqi Li Jingling Tang Yu Zhang Yaoyao Qi Yulei Wang Zhiwei Lu | 2021 | High Power Laser Science and Engineering2021，9，3： | 7 |
| 3 | Intellectual Property Protection and High-quality Development of Grape Industrial Clusters in Xinjiang显示文摘This paper introduced the grape industry in Xinjiang and its agricultural intellectual property resources,and analyzed six major problems such as the ineffective leading role of intellectual property rights in high-quality development.Finally,it proposed eight strategies to build a national-level regional fine-grain breeding base for grapes and develop“agricultural chips”in the context of the strategy of strengthening the country with intellectual property and innovation-driven development strategy. | Miaomiao XU Jinjin WANG Yulan BAI Jin ZENG Yuanpeng SUN Zhiguo SUN | 2023 | Asian Agricultural Research2023，15，5： | 2 |
| 4 | Intellectual Property Protection and New Development Pattern Construction of Xinjiang Jujube显示文摘'Three new developments'is the guiding ideology of Chinese-style high-quality development in the new era.Jujube(Zizyphus jujube Mill.)is a plant of Zizyphus of Rhamnaceae,which originated in China and has been listed as one of the'five fruits'since ancient times.Xinjiang is the most important jujube producing area in China,and its yield has accounted for 50%of the national jujube yield.In the five prefectures and cities of southern Xinjiang,as well as the regimental farms of southern and eastern Xinjiang of Xinjiang Production and Construction Corps,the jujube industry is an advantageous characteristic industry in agriculture.This paper studied Xinjiang jujube industry and its agricultural intellectual property resources,analyzed six major issues to be further implemented,such as the'three new developments'thinking and the strategy of building an intellectual property power,and puts forward eight strategies such as coordinating the two markets and two resources to accelerate the construction of a new development pattern and dual circulation of jujube. | Miaomiao XU Yulan BAI Jinjin WANG Yuanpeng SUN Jin ZENG Zhiguo SUN | 2023 | Asian Agricultural Research2023，15，7： | 2 |
| 5 | Microstructure and magnetic properties of CoFe_2O_4 thin films deposited on Si substrates with an Fe_3O_4 under-layer显示文摘The microstructure and magnetic properties of cobalt ferrite thin films deposited by the sputtering method on an Fe3O4 under-layer were investigated at different post-annealing temperatures.Results show that the Fe3O4 under-layer can accelerate the grain growth of cobalt ferrite films due to the phase transformation of the Fe3O4 under-layer at about 400°C-500°C.By introducing the Fe3O4 under-layer,cobalt ferrite nanocrystalline thin films with high coercivity can be obtained at lower post-annealing temperatures. | ZHONG ZhiYong ZHANG HuaiWu TANG X iaoLi JING YuLan BAI FeiMing LIU Shuang | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，7： | 1 |
