| 1 | Design and physical model experiment of an attitude adjustment device for a crawler tractor in hilly and mountainous regions显示文摘To address the problems of difficult leveling and poor stability of hill crawler tractors,an attitude adjustment device based on a parallel four-bar mechanism was designed,and the mechanical reasons for the sideslip instability of hill crawler tractors were analyzed.On this basis,a posture adjustment mechanism based on a parallel four-bar mechanism was proposed,and the structure of the complete attitude adjustment device was designed.To ensure that this device meets the strength requirements during operation,a mechanical analysis of the key components(active rocker and slave rocker)was carried out to accommodate the load during leveling.Based on ANSYS software,a finite element simulation analysis was used to determine the maximum stress position of the active and slave rockers.Finally,to verify the accuracy of the above simulation analysis results and determine the influence rules of the lateral slope angle,longitudinal slope angle and loading quality on the abovementioned maximum stress,a physical model test bench of the attitude adjustment device was built.An orthogonal regression experiment was carried out with the maximum stresses of the active and slave rockers as the test indices.The experimental data were analyzed by Design-Expert 10 software,and the results show that the order of the primary and secondary factors influencing the maximum stress of the active rocker was the loading mass,lateral slope angle and longitudinal slope angle.The order of the factors influencing the maximum stress of the slave rocker was the longitudinal slope angle,lateral slope angle and loading mass.The active and slave rockers meet the strength requirements.This work provides technical support for the production of hill crawler tractor physical prototypes. | Jingbin Sun Chong Meng Yazhou Zhang Guoping Chu Yanjie Zhang Fuzeng Yang Zhijie Liu | 2020 | Information Processing in Agriculture2020,7,3: | 5 |
| 2 | Initial carbon release characteristics, mechanisms and denitrification performance of a novel slow release carbon source显示文摘External carbon source addition is one of the effective methods for the treatment of wastewater with low carbon to nitrogen ratio(C/N). Compared with fast-release liquid carbon sources, slow-release solid carbon sources are more suitable for the denitrification process. A novel slow-release solid carbon source(corncob-polyvinyl alcohol sodium alginatepoly-caprolactone, i.e. CPSP) was prepared using corn cob(CC) and poly-caprolactone with polyvinyl alcohol sodium alginate as hybrid scaffold. The physical properties and carbon release characteristics of CPSP and three other carbon sources were compared. CPSP had stable framework and good carbon release performance, which followed the second order release equation. The formic acid, acetic acid, propionic acid and butyric acid released from CPSP accounted for 8.27% ± 1.66 %, 56.48% ± 3.71 %, 18.46% ± 2.69% and 16.79% ± 3.02% of the total released acids respectively. The start-up period of CPSP was shorter than that of the other carbon sources in denitrification experiment, and no COD pollution was observed in the start-up phase(25–72 h) and stable phase(73–240 hr). The composition and structure of the dissolved organic compounds released by CPSP and other carbon sources were analyzed by UV-Vis absorption spectroscopy and three-dimensional fluorescence spectroscopy,which indicated that CPSP was more suitable for denitrification than the other studied carbon sources. | Congyu Li Haiyan Wang Guokai Yan Weiyang Dong Zhaosheng Chu Huan Wang Yang Chang Yu Ling Yanjie Zhang | 2022 | Journal of Environmental Sciences2022,34,8: | 5 |

| 4 | A Water-Soluble Photothermal Host–Guest Complex with pH-Sensitive Superlarge Redshift Absorption显示文摘Near infrared(NIR)absorbers for photothermal therapy are arousing great attention in tumor diagnosis and ablation.However,the inevitably wide distribution of NIR absorbers generally causes equal photothermal injuries to tumor tissues and healthy tissues.An initiative targeting strategy based on pH-sensitive redshift absorption has been proposed for NIR-induced hyperthermia only in tumor tissue.In this work,we develop a NIR absorber with superlarge redshift from the middle visible light region to NIR light region once the pH value drops. | Xiao-Qi Xu Hongguang Liao Haocheng Liu Yanji Chu Yonglin He Yapei Wang | 2021 | CCS Chemistry2021,3,10: | 1 |

| 9 | Effectiveness of Mind-Body Exercise on Burnout and Stress in Female Undergraduate Students显示文摘This study was to investigate the effects of mind-body exercise on burnout and perceived stress among female undergraduate students.A sample of 146 female undergraduate students took part in this study.They were assigned to mind-body exercise group(n=91)and control group(n=55).Mind-body exercise group received three 90-min sessions of Baduanjin exercise per week lasting for 12-weeks.There was no intervention in the control group.The Maslach Burnout Inventory-Student Survey was used to assess burnout level,and the 10-item perceived stress scale was used to assess stress level.Significant decreases in emotional exhaustion(p<0.001),cynicism(p<0.001)and perceived stress(p<0.001)were found in the mind-body exercise group compared with control group.Furthermore after 12-week mind-body exercise,emotional exhaustion,cynicism and perceived stress had greater reduction.Mind-body exercise(Baduanjin)may be considered an alternative strategy to reduce burnout and perceived stress in female undergraduate students. | Xiaohong Zhu Tongyang Chu Qian Yu Jinming Li Xingyu Zhang Yanjie Zhang Liye Zou | 2021 | International Journal of Mental Health Promotion2021,23,3: | 0 |
| 10 | Second Near-Infrared Photothermal Therapy with Superior Penetrability through Skin Tissues显示文摘Photothermal therapy(PTT)triggered by second near-infrared(NIR-II)light(1000–1400 nm)has shown great potential in tumor ablation because of its good tissue penetrability.However,NIR-II PTT still cannot treat tumors underneath skin because of the light scattering effect of skin components.This research aims to promote the NIR-II penetrability of skin tissue by weakening the light scattering effect from the refractive index inhomogeneity among skin constituents. | Yanji Chu Shenglong Liao Hongguang Liao Yang Lu Xiaodong Geng Di Wu Jian Pei Yapei Wang | 2022 | CCS Chemistry2022,4,9: | 0 |
