为了实现给水厂污泥的资源化利用,以某水厂污泥为例,分析了其理化性质与吸附除磷特性,并探究了玉米芯耦合给水厂污泥组合填料人工湿地系统在不同季节温度下的脱氮除磷效果。研究结果表明,给水厂污泥的平均铁、铝含量分别为(23.14±0.04)mg/g、(46.2±0.2)mg/g,磷饱和吸附容量为7.89 mg/g,污泥吸附磷的过程符合准二级动力学(R2=0.997)与Langumir模型(R2=0.979);湿地系统主要利用给水厂污泥吸附除磷,并依赖玉米芯进行异养反硝化脱氮;在HRT为1 d,进水氮、磷浓度满足GB 8978—1996《污水综合排放标准》一级A标准的条件下,常温条件下出水氮、磷浓度均达到GB 3838—2002《地表水环境质量标准》Ⅱ类水标准。

苯丙烷代谢途径是植物主要代谢途径之一,可产生黄酮、酚酸和木质素类等物质,这些物质不仅参与调控植物生长发育和抗逆等生理活动,还被用于预防和治疗疾病,是决定药用植物品质的关键因素之一。苯丙氨酸解氨酶(Phenylalanine ammonia-lyase,PAL)负责催化苯丙烷类代谢途径中第一个反应,是该途径的关键酶和限速酶。本文就药用植物中PAL基因的基本特性、表达调控机制等方面的研究进行综述,为进一步阐明药用植物中PAL的功能提供参考。

The effects of Ce addition(310 ppm and 1500 ppm)on the microstructure,texture and properties of ultrahigh-purity copper(99.99999%)were systematically studied using scanning electron microscopy(SEM),transmission electron microscopy(TEM)and electron backscattered diffraction(EBSD)analyses,combined with the microhardness and conductivity *** the microstructure of the as-cast and as-extruded samples,the addition of Ce refines the grain size of the ultrahigh-purity copper and the refinement effect of 310Ce alloy is greater than that of 1500Ce *** is due to the stronger compone nt supercooling and the accele rated recrystallization caused by lower Ce co *** addition,Ce can react with Cu to form the Cu-Ce eutectic phases,which are deformable during the hot ***,the added Ce can weaken the texture,showing a variation of brass recrystallization(BR),rotated cube,copper and S texture components,which depends on the recrystallization,the particle stimulated nucleation(PSN)as well as the stacking fault energy(SFE).Most remarkably,the introduction of Ce enhances the hardness of the ultrahigh-purity copper without obviously reducing its *** major{111}orientations and the stress distributions are responsible for such a superior conductivity of the Ce-containing alloys.

To generate dance that temporally and aesthetically matches the music is a challenging problem in three ***,the generated motion should be beats-aligned to the local musical ***,the global aesthetic style should be matched between motion and *** third,the generated motion should be diverse and *** address these challenges,we propose ReChoreoNet,which re-choreographs high-quality dance motion for a given piece of music.A data-driven learning strategy is proposed to efficiently correlate the temporal connections between music and motion in a progressively learned cross-modality embedding *** beats-aligned content motion will be subsequently used as autoregressive context and control signal to control a normalizing-flow model,which transfers the style of a prototype motion to the final generated *** addition,we present an aesthetically labelled music-dance repertoire(MDR)for both efficient learning of the cross-modality embedding,and understanding of the aesthetic connections between music and *** demonstrate that our repertoire-based framework is robustly extensible in both content and *** quantitative and qualitative experiments have been carried out to validate the efficiency of our proposed model.
