| 1 | Development of a mobile powered hole digger for orchard tree cultivation using a slider-crank feed mechanism显示文摘The powered hole digger is one of the most important orchard machines.The power consumption of its drill is an important factor affecting the performance and operation of the device.The drill power consumption of the digger at a constant feed rate is directly proportional to digging depth.This research discusses a newly designed powered hole digger using a slider-crank feed mechanism.The motion characteristics of the powered hole digger feeding mechanism was analysed.Additionally,an experiment was conducted to determine the characteristics of the drill power consumption.It can be concluded that there was a positive correlation between the drill power consumption and the powered hole digger feed rate.It was observed that when digging depth reached 200 mm,the drill power consumption reached the maximum power rating;subsequently the drill power consumption decreased with an increase of digging depth.When the drill reached the bottom of the hole,the power consumption of the new powered hole digger did not exceed the maximum designed power rating,hence the drill motor would not stall. | Zong Wangyuan Wang Jingliang Huang Xiaomao Yu Dong Zhao Yingbiao Sean Graham | 2016 | International Journal of Agricultural and Biological Engineering2016，9，3： | 3 |

| 11 | Development characteristics and formation analysis of the Liangjia Village earth fissure in the Weihe Basin,China显示文摘Liangjia Village earth fissure,one of the 79 earth fissures along the Kouzhen-Guanshan fault located in the northern Weihe Basin,causes severe damage to buildings and farmlands.Since the late 1950s,40 earth fissures have occurred in a similar east-west(EW)direction parallel to the Kouzhen-Guanshan fault,and a further 39 earth fissures have occurred with north-west,east-north,or north-east orientations intersecting the fault.In this study,a case study of Liangjia Village earth fissure was conducted to investigate the mechanisms of fissure generation in detail.Geotechnical and geophysical methods including measurements,trenching,drilling,and seismic exploration were used to reveal the basic characteristics,geological background,and origin model of the Liangjia Village earth fissure.This earth fissure,with a total length of 800 m in 2014,runs EW parallel to the Kouzhen-Guanshan fault,and it has damaged buildings and farmlands by forming sinkholes,gullies,subsidence,and a scarp.The trenching results indicated that this fissure underwent multi-phase activity.Analysis of geological drilling and shallow seismic profiling results showed that the fissure also possessed characteristics of a synsedimentary fault.Regarding its genesis,the fissure was formed through the combined actions of three factors:an earthquake created the fissure,the Kouzhen-Guanshan fault controlled its development,and loess erosion and groundwater runoff subsequently enlarged the fissure.Regional extension first generated many buried faults along the hanging wall of the Kouzhen-Guanshan fault before seismic activity caused the buried faults to propagate to the surface,where loess erosion and ground-water runoff promoted the formation of the current earth fissure. | Junhua Zhu Jianwei Qiao Feiyong Wang Quanzhong Lu Yuyun Xia Ransheng Chen Haiyuan Zhao Jingliang Dong | 2020 | Frontiers of Earth Science2020，14，4： | 0 |
| 12 | A comparison study of hydrogen storage performances of SmMg_(11)Ni alloys prepared by melt spinning and ball milling显示文摘The melt spinning(MS) and ball milling(BM) technologies are thought to be efficient to prepare nanostructured Mg and Mg-based alloys for improving their hydrogen storage performances. In this paper, two technologies, viz. melt spinning and ball milling, were employed to fabricate the SmMg_(11)Ni alloy. The structure and hydrogen storage performance of these two kinds of alloys were researched in detail. The results reveal that the as-spun and milled alloys both contain nanocrystalline and amorphous structures. By means of the measurement of PCT curves, the thermodynamic parameters of the alloys prepared by MS and BM are ΔN_(Ms)(des) = 82.51 kJ/mol and ΔH_(BM)(des) = 81.68 kJ/mol, respectively, viz.ΔH_(MS)(des) > ΔH_(BM)(des). The as-milled alloy shows a larger hydrogen absorption capacity as compared with the as-spun one. The as-milled alloy exhibits lower onset hydrogen desorption temperature than the as-spun one. As to the as-milled and spun alloys, the onset hydrogen desorption temperatures are557.6 and 565.3 K, respectively. Additionally, the as-milled alloy shows a superior hydrogen desorption property than the as-spun one. On the basis of time that required by desorbing hydrogen of 3 wt% H_2, the as-milled alloy needs 1488.574,390 and 192 s corresponding to hydrogen desorption temperatures 593,613,633 and 653 K, while the as-spun alloy needs 3600,1020,778 and 306 s corresponding to the same temperatures. The dehydrogenation activation energies of the as-milled and spun alloys are 100.31 and105.56 kJ/mol, respectively, the difference of which is responsible for the much faster dehydriding rate of the as-milled alloy. | Yanghuan Zhang Meng Ji Zeming Yuan Jingliang Gao Yan Qi Xiaoping Dong Shihai Guo | 2018 | Journal of Rare Earths2018，36，4： | 0 |
