The economy of China has turned to the stage of high-quality development. In this sense,the connotation of regional innovation capacity should reflect more aspects, such as better economic effectiveness, people-centered philosophy of development and better living conditions. This study aims at establishing the evaluation index system of regional innovation capacity under high-quality perspective.Then the dynamic evaluation method based on gray correlation degree and TOPSIS is improved. And the improved method is applied to evaluate the regional innovation capacity under high-quality development perspective. The results show that: 1) The regional innovation capacity of Jiangsu, Zhejiang,Shanghai and Guangdong under high-quality development perspective is better than other regions,while the regional innovation capacity of Beijing-Tianjin-Hebei is imbalanced. Regional innovation capability of Fujian, Shandong, and Hainan from a high-quality perspective is at the middle and lower levels. 2) From the perspective of development trends, the gap of regional innovation capacity between Beijing, Jiangsu, Zhejiang, Shanghai, Guangdong and Fujian, Hebei, Shandong is gradually narrowing.3) An in-depth analysis of the regional innovation capability of the eastern provinces and cities from the perspective of high-quality development through different dimensions shows that Beijing, Guangdong, Jiangsu perform well in all dimensions, while Fujian and Hainan need to pay more attention to innovation input and the creation of a better innovation environment to enhance innovation output and promote innovation effectiveness. At last, based on above analysis, relevant policy recommendations are proposed.

Rice-duck co-culture is an integrated farming technology that benefits rice production, grain quality, and ecological sustainability in paddy fields. However, little is known about the effects of rice-duck co-culture on enzyme activity involved in the biosynthesis of 2-acetyl-1-pyrroline (2-AP), the volatile that gives fragrant rice its' distinctive and sought-after aroma. The present study aimed to examine the influence of rice-duck co-culture on the photosynthesis, yield, grain quality, rice aroma, and the enzymes involved in 2-acetyl-1-pyrroline biosynthesis in the cultivar Meixiangzhan 2 during the early and late rice growing seasons of 2016 in Guangzhou, China. We compared the rice grown in paddy fields with and without ducks. We found that rice-duck co-culture not only improved the yield and quality of fragrant rice grain, but also promoted the precursors of 2-AP biosynthesis formation and 2-AP accumulation in the grain. Grain 2-AP content in rice-duck co-culture was noticeably increased with 9.60% and 20.81% in early and late seasons, respectively. Proline and pyrroline-5-carboxylic acid (P5C) (precursors of 2-AP biosynthesis) and the activity of enzymes such as proline dehydrogenase (ProDH), ornithine aminotransferase (OAT) and Δ1 pyrroline-5-carboxylic acid synthetase (P5CS) were all improved by 10.15%–12.99%, 32.91%–47.75%, 17.81%–26.71%, 6.25%–21.78%, and 10.58%–38.87% under rice-duck co-culture in both seasons, respectively. Overall, our results suggest that rice-duck co-culture is an environmentally-friendly and sustainable approach to improving rice aroma and grain quality of fragrant rice.

In this paper, highly dispersive nanosized copper particles with a mean particle size of less than 6 nm are prepared by an environmentally friendly chemical reduction method. Non-toxic L-ascorbic acid acts as both reducing agent and antioxidant in ethylene glycol in the absence of any other capping agent. Transmission electron microscopy （TEM） is used to characterize the size and morphology of Cu nanoparticles. The results of UV-Vis spectroscopy （UV-Vis）, energy dispersive spectroscopy （EDS） and high resolution TEM （HRTEM） illustrate that the resultant product is pure Cu nanocrystals. The size of Cu nanoparticles is remarkably impacted by the order of reagent addition, and the investigation reveals the reaction procedure of Cu^2＋ ions and L-ascorbic acid.

目的探究血清维生素D状况对妊娠女性子代胎儿期长骨发育的影响。方法回顾性收集2018年7月至2020年6月在我院产前诊断中心就诊的第1胎妊娠女性1193例,均行产前胎儿超声检查与血清维生素D水平检测,根据第1次检测维生素D后的给药剂量分为基础剂量组(维生素D3,1600 IU/d,口服)、足量补充组(维生素D2注射液60万U/2周,肌肉注射),比较两组妊娠女性在治疗12周和24周时血清25-(OH)D水平及妊娠女性其胎儿长骨生长情况,采用多因素logistic回归分析胎儿长骨长度的相关影响因素。结果足量补充组相比基础剂量组在治疗8周、治疗12周、治疗24周均能明显提升妊娠女性血清25-(OH)D水平。两组妊娠女性在给予治疗12周[(4.93±0.75)cm对(4.61±0.73)cm,P<0.05]和治疗24周[(7.92±0.84)cm对(7.25±0.92)cm,P<0.05],足量补充组相比基础剂量组更能增加胎儿的长骨长度,尤以治疗24周时两组长骨的差异更为明显。母亲身高、基础维生素D水平、孕24周维生素D水平与胎儿长骨长度呈正相关。结论孕妇应保持相对较高的基础维生素D水平,并在孕期重视维生素D水平对胎儿的影响,足量补充维生素D对胎儿长骨发育具有重要意义。

Manganese oxide(Mn_(3)O_(4))is of great potential for lithium storage based on conversion reactions,but its application in rechargeable lithium batteries is severely hindered by the low electric conductivity and large volume variation during lithiation/delithiation.Herein,a biomimetic ear-of-wheat-like nanocomposite of ultrafine Mn_(3)O_(4)nanoparticles(MONPs)and multi-walled carbon nanotubes(MWCNTs)is prepared using a facile solvothermal method.The tightly packed MONP"cereal-grains"are directly grown and uniformly interspersed on the outer surface of skeleton MWCNT"central stems."The ultrafine MONPs are favorable to lithium incorporation/extraction while the interconnected MWCNT skeletons provide a highly conducting network for electron transportation.Consequently,a high reversible capacity of 810 m A h g^(-1)is obtained at the current density of 40 m A g^(-1).After 50 cycles at 160 m A g^(-1),the nanocomposite still delivers a capacity up to 796 m A h g^(-1),which is higher than twice of that of pure Mn_(3)O_(4)nanopowders.The unique nanostructure and the facile biomimetic method can be widely extended to design and explore various highperformance energy materials for lithium/sodium ion batteries and fuel cells.

【目的】探究饲粮表观代谢能(apparent metabolizable energy,AME)水平对1~28日龄三穗鸭生长性能、屠宰性能及血浆生化指标的影响,并根据回归模型估算AME需要量。【方法】试验选取336只健康1日龄三穗鸭公鸭,采用单因子完全随机设计将试验鸭平分为6组,每组7个重复,每个重复8只鸭。试验鸭分别饲喂AME为10.92、11.38、11.80、12.26、12.68和13.14 MJ/kg的玉米-豆粕型饲粮,试验期28 d。试验结束后,统计生长性能、屠宰性能,并检测血浆生化指标。【结果】饲粮AME水平显著影响日增重、料重比和腹脂率(P0.05);饲粮AME水平显著影响血浆谷草转氨酶(AST)活性(P0.05)。基于直线-折线回归模型,以料重比、日增重和腹脂率为评价指标估测1~28日龄三穗鸭AME最低需要量分别为11.83、11.42和12.24 MJ/kg。【结论】饲喂11.38 MJ/kg AME饲粮可有效改善1~28日龄三穗鸭日增重和料重比,并降低腹脂率。综合考虑,1~28日龄三穗鸭AME最适需要量为11.42~12.24 MJ/kg。

AlN ceramics were prepared by plasma activation sintering(PAS)with compound additives yttrium acetylacetonate(Y(acac)_(3))and melamine(C_(3)H_(6)N_(6)).The effects of compound additives on the microstructure,density,and thermal properties of Al N ceramic were studied.Y(acac)3and C_(3)H_(6)N_(6)can form Y_(2)O_(3),residual organic carbon and reducing gas during the heating process,which improves the Al N sintering performance at a temperature of 1700℃and the bulk thermal conductivity.When the content of Y(acac)_(3)is 10 wt%and C_(3)H_(6)N_(6)is 3 wt%,the thermal conductivity of Al N ceramics is 105.6 W/(m·K),which is much higher than that of Al N ceramics with Y_(2)O_(3)under the same sintering conditions.This work provides theoretical reference for the preparation of high-performance Al N ceramic.
