柴油机颗粒捕集器是能够有效减少颗粒物排放的装置,而颗粒捕集效率很大程度取决于其内部的气流分布。基于体积平均法建立了捕集器内的三维流体模型,并对流场分布进行分析。在六种入口轴向速度下,研究了进排气通道的平均轴向速度以及多孔壁面的平均渗流速度特点。结果表明:进气通道的平均速度非线性减小,排气通道平均速度非线性增大,交叉点之后平均速度的变化明显加快;多孔壁面的平均渗流速度先减小后增大;进、排气通道平均轴向速度交叉点以及多孔壁面平均渗流速度的最小值出现在捕集器中心处之后。

村级组织负责人“一肩挑”是新时代加强党的全面领导的一项有力制度安排,能够对村庄组织、利益、价值进行有效整合,继而推进以党为中心的村域治理共同体构建.首先,在组织层面,能够在党的领导下理顺纵横向治理体系,使之有效运转起来,为村域治理共同体构筑坚实组织基础;其次,在利益层面,能够将民主协商贯穿村级治理全过程,在利益诉求收集、协商和落实的过程中,提供公共利益基础;最后,在价值层面,可将宣传教育与行动示范等举措与村级日常治理予以深度融合,不断凝聚各主体对村庄公共生活的集体意识,铸牢价值基础.因此,必须进一步探索村级组织负责人“一肩挑”与村域治理共同体的深度耦合机制,以期实现乡村善治及其全面振兴.

In plants, photoperiod is an important cue for determining flowering. The floral transition in Arabidopsis thaliana is earlier under long-day （LD） than under short-day （SD） conditions. Flowering of Arabidopsis plants under SD conditions is mainly regulated by the plant hormone gibberellin （GA）. Here, we report two WRKY transcription factors function oppositely in controlling flowering time under SD conditions. Phenotypic analysis showed that disruption of WRKY12 caused a delay in flowering, while loss of WRKY13 function promoted flowering. WRKY12 and WRKY13 displayed negatively correlated expression profiles and function successively to regulate flowering. Molecular and genetic analyses demonstrated that FRUITFULL （FUL） is a direct downstream target gene of WRKY12 and WRKY13. Interestingly, we found that DELLA proteins GIBBERELliN INSENSITIVE （GAI） and RGA-liKE1 （RGL1） interacted with WRKY12 and WRKY13, and their interactions interfered with the transcriptional activity of the WRKY12 and WRKY13. Further studies suggested thatWRKY12 and WRKY13 partly mediated the effect of GA3 on controlling flowering time. Taken together, our results indicate that WRKY12 and WRKY13 oppositely modulate flower- ing time under SD conditions, which at least partially involves the action of GA.

Recent studies in Arabidopsis have revealed that some vq motif-containing proteins physically interact with WRKY transcription factors; however, their specific biological functions are still poorly understood. In this study, we confirmed the interaction between VQ1o and WRKY8, and show that VQ1o and WRKY8 formed a complex in the plant cell nucleus. Yeast two-hybrid analysis showed that the middle region of WRKY8 and the vq motif of vqlo are critical for their interaction, and that this interaction promotes the DNA-binding activity of WRKY8. Further investigation revealed that the VqlO protein was exclusively localized in the nucleus, and VQ1o was predominantly expressed in siliques, vQ1o expression was strongly responsive to the necrotrophic fungal pathogen, Botrytis cinerea and defense-relatedhormones. Phenotypic analysis showed that disruption of VQlo increased mutant plants susceptibility to the fungal pathogen B. cinerea, whereas constitutive-expres- sion of VQlo enhanced resistance to B. cinerea. Consis- tent with these findings, expression of the defenserelated PLANT DEFENSIN1.2 （PDFt2） gene was decreased in vqlo mutant plants, after B. cinerea infection, but increased in vQ1o-overexpressing transgenic plants. Taken together, our findings provide evidence that VQlo physically interacts with WRKY8 and positively regulates plant basal resistance against the necrotrophic fungal pathogen B. cinerea.
