The composition of biomass pyrolysis gas is complex,and the selective separation of its components is crucial for its further utilization.Metal-incorporated nitrogen-doped materials exhibit enormous potential,whereas the relevant adsorption mechanism is still unclear.Herein,16 metal-incorporated nitrogen-doped carbon materials were designed based on the density functional theory calculation,and the adsorption mechanism of pyrolysis gas components H2,CO,CO_(2),CH_(4),and C2H6 was explored.The results indicate that metal-incorporated nitrogen-doped carbon materials generally have better adsorption effects on CO and CO_(2)than on H_(2),CH_(4),and C_(2)H_(6).Transition metal Mo-and alkaline earth metal Mg-and Ca-incorporated nitrogen-doped carbon materials show the potential to separate CO and CO_(2).The mixed adsorption results of CO_(2)and CO further indicate that when the CO_(2)ratio is significantly higher than that of CO,the saturated adsorption of CO_(2)will precede that of CO.Overall,the three metal-incorporated nitrogen-doped carbon materials can selectively separate CO_(2),and the alkaline earth metal Mg-incorporated nitrogen-doped carbon material has the best performance.This study provides theoretical guidance for the design of carbon capture materials and lays the foundation for the efficient utilization of biomass pyrolysis gas.

Metasequoia glyptostroboides(M.glyptostroboides)is a unique plant species related to relic flora in China.It plays a positive role in afforestation and its long-term protection with high paleoclimate research value.However,due to the nutrients-supply deficiency,it is a big challenge to cultivate the high-quality seedlings of M.glyptostroboides.In this study,a pot experiment in a greenhouse environment was carried out to identify the effect of N-exponential fertilization on the growth and nutrient distribution of M.glyptostroboides seedling.The M.glyptostroboides rooted seedlings with 12-month growth were chosen.Different N fertilizer levels with conventional fertilization(CF:5.0 g seedling^(−1)),exponential fertilization including EF1,EF2,EF3 and EF4 were determined.The relevant growth indexes were measured after 210-day growth.The results indicated that non-significant differences in seedlings’height and ground diameter were found among the above treatments(P>0.05);At the same time,N-exponential fertilization promoted the M.glyptostroboides’s biomass in different organs(P<0.05),with the maximum total biomass under EF3 treatment.The N accumulation in root and stem of the N-exponential fertilization treatments were increased in to some extent(P<0.05).The maximum N accumulation was also found under EF3 treatment.Therefore,steady-state nutrition and superior growth performance of M.glyptostroboides could be obtained by N-exponential fertilization of 5.0 g cutting^(−1).

Because pixel values of foggy images are irregularly higher than those of images captured in normal weather(clear images),it is difficult to extract and express their texture.No method has previously been developed to directly explore the relationship between foggy images and semantic segmentation images.We investigated this relationship and propose a generative adversarial network(GAN)for foggy image semantic segmentation(FISS GAN),which contains two parts:an edge GAN and a semantic segmentation GAN.The edge GAN is designed to generate edge information from foggy images to provide auxiliary information to the semantic segmentation GAN.The semantic segmentation GAN is designed to extract and express the texture of foggy images and generate semantic segmentation images.Experiments on foggy cityscapes datasets and foggy driving datasets indicated that FISS GAN achieved state-of-the-art performance.

The hyperaccumulator Sedum alfredii Hance(S.alfredii)may be employed for zinc(Zn)and cadmium(Cd)-polluted soil remediation.However,the low phytoremediation efficiency,related to the low biomass production,limits its use with that purpose.In this experiment,nitrogen(N),phosphorus(P),and potassium(K)fertilizers,and organic manure were applied to investigate the phytoremediation ability of S.alfredii.Hydroponic and pot experiments were conducted using Zn-Cd polluted soil.The hydroponic experiment indicated that appropriate fertilizer application could increase(p0.8 mmol L^(−1))P supply decreased growth,and Zn/Cd accumulation in whole plants of the studied species.The 0.1 mmol L^(−1) P was an optimal dosage for S.alfredii biomass production and Zn/Cd accumulation in shoots.The supply levels within the range from 0.3 to 1 mmol L^(−1) K could significantly improve the biomass production of S.alfredii and its capability to accumulate Zn and Cd in the biomass.The 0.5 mmol L^(−1) K was an optimal dosage for the whole biomass production and Zn accumulation in shoots,while the 1 mmol L^(−1) was an optimal K dosage for Zn accumulation in shoots,which was 17.2%higher than the control.Moreover,the soil pot experiment showed that the combination of organic(fermented manure)and inorganic fertilizers made significant effects on the Zn and Cd-polluted soil remediation by S.alfredii.These effects varied,however,with the application of different proportions of N,P,K and organic matter.The Zn accumulation by S.alfredii reached the highest efficiency ability under the highest fertilizer mixing rate(N:50 mg kg^(−1),P:40 mg kg^(−1),K:1

鉴于现行就业统计方式不能及时、准确反映经济运行形势,如何利用大数据对现有统计指标进行补充成为一个重要问题。鉴于短视频消费已经成为当今社会主要的休闲娱乐方式,文章将短视频消费纳入效用函数,通过失业人员与雇员在时间分配上的差异,揭示全社会用于观看短视频的时间与就业率之间存在的理论联系。通过计量分析,研究发现基于抖音在线人数计算的估计值与描述失业者寻找工作行为的百度搜索指数呈现正相关关系,可以借助短视频观看时长变动说明失业者寻找工作行为的变化。基于抖音在线人数估计的劳动参与率与16—24岁城镇调查失业率存在显著负相关关系,两者的皮尔逊相关系数为-0.862,因此估计的劳动参与率可以作为城镇调查失业率,特别是16—24岁劳动力调查失业率的补充。

本文通过梳理并分析道家思想在西方传播历程,阐述西方道家思想研究实现跨文化、跨学科的生态转向的过程。总体而言,道家思想传播在西方共经历三个发展阶段,分别为“归化思想”阶段、“替代智慧”阶段,以及作为生态主义理论建构重要参考的阶段。研究认为,道家思想在西方逐步摆脱了早期的基督教中心主义的研究桎梏后,其关联性思维和非二元思想的特质得到了广泛关注,因而与生态主义的联系随研究发展而愈发紧密,并成为当代生态主义建构的重要理论来源。
