In this work,we demonstrate that ultraviolet(UV)laser photolysis of hydrocarbon species alters the flame chemistry such that it promotes the diamond g.owth rate and film *** emission spectroscopy and laser-induced fluorescence demonstrate that direct UV laser irradiation of a diamond-forming.combustion flame produces a larg. amount of reactive species that play critical roles in diamond g.owth,thereby leading.to enhanced diamond *** diamond g.owth rate is more than doubled,and diamond quality is improved by 4.2%.Investig.tion of the diamond nucleation process sug.ests that the diamond nucleation time is sig.ificantly shortened and nondiamond carbon accumulation is g.eatly suppressed with UV laser irradiation of the combustion flame in a laser-parallel-to-substrate g.ometry.A narrow amorphous carbon transition zone,averag.ng.4 nm in thickness,is identified at the film–substrate interface area using.transmission electron microscopy,confirming.the suppression effect of UV laser irradiation on nondiamond carbon *** discovery of the advantag.s of UV photochemistry in diamond g.owth is of g.eat sig.ificance for vastly improving.the synthesis of a broad rang. of technically important materials.

肠道菌群对宿主健康的作用已被广泛证实,而饮食习惯对肠道菌群产生深远的影响。近年来,通过调整饮食结构实现对肠道菌群的靶向调节,从而改善宿主代谢,促进宿主健康已取得显著成效。g.rdon等对微生物群导向性食物的一系列研究,与赵立平团队对由全谷物、中药和益生元组成的配方食物的一系列研究均发现,补充特定的食物成分可以有效增加特定的菌种、菌株以及“功能群”的丰度,从而有效改善宿主表型。本文拟对这两个系列的研究结果进行分析和总结,以期为今后探寻更好的以优化肠道微生物群为导向的饮食干预方案提供参考。

在新冠肺炎疫情期间,中国采取的管制封锁措施大幅减少了交通和工业排放,但农业排放没有受到影响,甚至有所增加.通过全国大气氨浓度地面监测、实时连续观测和卫星观测等手段,我们发现,新冠肺炎疫情管制措施实施期间中国大气氨浓度大范围显著增加,上升幅度在农村地区最为明显(增加22%),在城市和偏远地区变化不明显;而且,管控期间大气氨浓度上升幅度与2015~2019年相同月份相比更大.基于大气化学模式模拟发现,中国北方大气氨浓度上升主要是由农业氨排放增加所致.随着未来我国二氧化硫和氮氧化物等酸性气体排放控制的强化,农业氨排放的协同减排对于进一步削减大气PM污染、提升空气质量尤为重要.进一步分析表明,疫情期间50%农业氨排放可有效抵消氨浓度上升造成的二次无机气溶胶的形成.

罗汉果是广西大宗道地药材,具有润肺止咳的功效,其所含低热量的罗汉果甜苷备受人们欢迎。随着罗汉果人工种植面积的不断扩大,其病害问题日益突出,质量和产量均受到严重影响,已成为制约罗汉果产业发展的重要因素之一。目前已报道的罗汉果病害有罗汉果病毒病、根结线虫病、青枯病、斑枯病、芽枯病、炭疽病、白绢病和根腐病等,其中病毒病和根结线虫病是主要病害,发生普遍、危害性大。文章综述了罗汉果病害的发病症状、病原、发生规律及防治方法等研究现状,指出当前罗汉果病害研究主要聚焦于罗汉果病毒病和根结线虫病,但研究深度不够,生产中罗汉果病毒病和根结线虫病问题依然严峻;提出建立快速、简便、特异性强的罗汉果病毒病检测方法,制定和完善罗汉果病毒检测规程;完善罗汉果脱毒苗生产技术体系,做到组培苗不带病毒,育苗基质不带线虫;重视田间综合防治技术协同研究,以减少病毒和线虫传播;加强对罗汉果病毒病和根结线虫病防治的宣传,指导农户科学合理种植;加强罗汉果抗病毒和抗线虫种质资源的收集、筛选与利用。针对今后罗汉果病害重点研究方向,认为应系统开展“寄主、病原物、环境”三角互作关系研究,建立绿色防控技术体系,选育抗病品种,以期为罗汉果病害的综合防治提供参考,推动罗汉果产业的高质量发展。

The Larg. sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） g.neral survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, g.laxies and QSOs. Objects in both the pilot survey and the first year reg.lar survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in Aug.st 2012. The reg.lar survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing.2 955 336 spectra, of which 1 790 879 spectra have observed sig.alto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are g.laxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalog. with measured parameters： late A,Fg.-type stars with hig. quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey desig., the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalog. is also provided.
