During the sustainable development of land surface system,different territories undertake different functions.The understanding and representation of territorial differentiation of the land surface system is the main purpose of comprehensive function regionalization research.Focusing on the theoretical gap of comprehensive geographical regionalization,that is,the spatial decoupling of the physical environment and human activities,the non-nested relationship of spatial scale transformation,and the persistence and uncertainty of the dynamic evolution of territorial functions,this research proposed the identification principles and division methods of comprehensive functional regions.Based on the major function zoning in China,the systematic classification method with function orientation was employed to delineate the comprehensive functions of each territory,such as ecological security,food production and urban development.Then,the geographical regionalization method,which follows the principles of interconnection of different regionalization objectives at different levels and a combination of top-down decomposition and bottom-up aggregation,was used to determine the geographic boundaries.To meet the objective requirements of flexible and dynamic boundaries,two sets of land regionalization schemes for 2035 and 2050 were finally formed,each of which had three spatial levels.The first-level regionalization identified four major regions,which comprehensively represented the relatively stable state of China’s land development and protection pattern under the leading role of physical environment differentiation.The second-level regionalization identified 12 regions,which comprehensively represented the spatial layout of a new development pattern of multi-and inter-provinces coordinating the innovation chain,industrial chain and supply chain based on a relatively independent and complete natural carrier.The third-level regionalization identified 80 sub-regions,which comprehensively represented the functional differentiat

With the development of Unmanned Aerial Vehicle(UAV)sprayers,the application of low-volume spraying of harvest-aid and other agrochemicals to cotton using UAVs is becoming a new agronomic trend worldwide.The effect of spray volume and canopy density for UAV spraying is significant but was rarely studied.In this study,five representative spray volumes were explored to examine the effect of spray volume on deposition and harvest-aid efficacy for cotton using a UAV sprayer.To explore the effect of canopy density,similar tests were carried out in a field located nearby with a lower leaf area index(LAI).A conventional trailer boom sprayer was selected for comparison.Different spray volumes had a significant effect on defoliation,but had no significant effect on boll opening and fiber quality.A higher defoliation rate was achieved in the lower LAI field.The total rate of defoliation using the UAV was inferior to the boom sprayer in the high LAI field for lower deposition and defoliation rate in the lower canopy.Considering the deposition,defoliation rate,and working efficiency,a spray volume of 15.0 L/hm^(2) with an average droplet size of 150μm is recommended for UAV application.

Ltd. Zibo 255000 China

The temperature dependence of the dynamic viscosity of Cu9In4 intermetallics melt has been investigated in five kinds of different heating and cooling processes with a torsional oscillation viscometer, It has been found that the viscosity of all Cu9In4 intermetallics decreases with increasing temperature in five kinds of different thermal processes. Thermal history has considerable effect on the viscosity. The viscosity in the cooling process with high superheating is greater than that in the cooling process with low superheating. The viscosity in the heating process is greater than that in the cooling process. No anomalous change in viscosity is measured in three kinds of cooling processes with low superheating. The anomalous change occurs at about 1050℃ in cooling with high superheating and at 800℃ in heating. Furthermore, the structural variation in different thermal processes has also been discussed on the basis of the change in viscosity and DSC analysis.

Background:The clinical features of enthesitis in patients with psoriatic arthritis(PsA)have been reported in some Western countries,but data in China are very limited.This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts.Methods:Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis(CREPAR)(December 2018 to June 2021)were included.Data including demographics,clinical characteristics,disease activity measures,and treatment were collected at enrollment.Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada(SPARCC),Maastricht ankylosing spondylitis enthesitis score(MASES),and Leeds enthesitis index(LEI)indices.A multivariable logistic model was used to identify factors related to enthesitis.We also compared our results with those of other cohorts.Results:In total,1074 PsA patients were included,308(28.7%)of whom had enthesitis.The average number of enthesitis was 3.3±2.8(range:1.0–18.0).More than half of the patients(165,53.6%)had one or two tender entheseal sites.Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis,reported a higher proportion of PsA duration over 5 years,and had a higher percentage of axial involvement and greater disease activity.Multivariable logistic regression showed that axial involvement(odds ratio[OR]2.21,95%confidence interval[CI],1.59–3.08;P<0.001),psoriasis area and severity index(PASI)(OR:1.03,95%CI:1.01–1.04;P=0.002),and disease activity score 28-C reactive protein(DAS28-CRP)(OR:1.25,95%CI:1.01–1.55;P=0.037)were associated with enthesitis.Compared with the results of other studies,Chinese patients with enthesitis had a younger age,lower body mass index(BMI),a higher rate of positive human leukocyte antigen(HLA)-B27,more frequent dactylitis,and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs’(csDMARDs)use.Conclusions:Enthesitis is a common condition among Chinese patients with PsA.It is import

The authors introduce and investigate the T_C-Gorenstein projective,L_CGorenstein injective and H_C-Gorenstein flat modules with respect to a semidualizing module C which shares the common properties with the Gorenstein projective,injective and flat modules,respectively.The authors prove that the classes of all the T_C-Gorenstein projective or the H_C-Gorenstein flat modules axe exactly those Gorenstein projective or fiat modules which are in the Auslander class with respect to C,respectively,and the classes of all the L_C-Gorenstein injective modules axe exactly those Gorenstein injective modules which are in the Bass class,so the authors get the relations between the Gorenstein projective,injective or flat modules and the C-Gorenstein projective,injective or flat modules.Moreover,the authors consider the T_C(R)-projective and L_C(R)-injective dimensions and T_C(R)-precovers and L_C(R)-preenvelopes.Finally,the authors study the H_C-Gorenstein flat modules and extend the Foxby equivalences.

Ltd.Beijing 100010China

Horizontal feeding devices and plate hob chopping devices are the key component of silage maize harvester.To solve the problem of feeding blockage,reduce energy consumption,and improve the chopping quality of the chopping device a horizontal different diameter five-rollers device(HDDFD)was designed and the plate hob chopping device was simultaneously optimized and analyzed.Through the dynamic analysis,the feeding conveying speed was determined to be 2.0-4.5 m/s.The distance equation of the actual and theoretical cutting-edge curve and the position of the fixed blade were finally obtained.Single factor and response surface orthogonal tests in the bench site were carried out with feeding speed,rotating speed of chopping cylinder,feeding amount,and feeding direction as influencing factors,standard grass length rate(SGLR),and energy consumption per unit mass(ECPUM)as evaluation indexes.The optimal working parameters for chopping performance could be concluded as a feeding speed of 3.39 m/s,rotating speed of the chopping cylinder of 1016.17 r/min,feeding amount of 8.04 kg/s,and feeding direction of 52.2°.In addition,the SGLR and ECPUM were obtained as 95.35%and 37.63 kJ/kg,respectively.The relative error between the experimental results with round parameter combination and the predicted value was verified to be less than 5%.Field tests verified the reliability of the optimized feeding and chopping device.It can be seen that the HDDFD and optimized plate hob chopping device can meet the requirements of mechanized silage harvesting which obviously improves the working quality and reduce the energy consumption of chopping.
