Response mechanism of soil microorganisms to simulated precipitation in the source wetland of Qinghai Lake

Ecological Processes 2024年第2期 61-71页

作者： xinye wang Ni Zhang Kelong Chen Tiexi Chen Desheng Qi Yuanxi Ma School of Geographical Sciences Qinghai Normal University National Positioning Observation and Research Station of Qinghai Lake Wetland Ecosystem in Qinghai National Forestry and Grassland Administration Key Laboratory of Tibetan Plateau Land Surface Processes and Ecological Conservation(Ministry of Education) Qinghai Normal University School of Geographical Sciences Nanjing University of Information Science and Technology Qinghai Provincial land spatial Planning Research Institute

Background Changes in precipitation patterns crucially impact soil microbial communities, and the ecosystem in Qinghai-Tibet Plateau(QTP) is highly vulnerable to climate change. However, we do not fully understand how soil microbial communities in the source wetlands of QTP respond to changes in precipitation. In this study, we employed advanced techniques such as high-throughput sequencing and metabolomics to investigate how soil microbial communities in a source wetland of Qinghai Lake respond to changes in precipitation after quadrennial precipitation *** Our findings showed that the predominant microbiota in the source wetland was Proteobacteria. Interestingly, alterations in precipitation levels, whether increased or reduced, did not significantly impact the diversity or functional groups of the microbial community. However, the structure of the microbial community did respond notably to changes in precipitation, leading to shifts in the relative abundance of Spirochaetes and Treponema. A notable finding was that reduced precipitation levels(– 25% and-50%) and mild increases in precipitation(25%) within the region contributed to increased soil carbon content. However, this effect ceased to manifest when precipitation increased by 50%. Additionally, the reduction in precipitation prompted the release of soil metabolites like syringic acid and aldosterone, while enhanced precipitation resulted in a decrease in aldosterone *** Precipitation changes altered the relative abundance of soil microbial communities and metabolites, which was conducive to increasing carbon storage in this alpine wetland.

基于高通量测序技术和数理统计手段,以小麦曲(原曲)为对照,探究按10%、20%和30%比例加入绿茶制曲,对大曲发酵过程理化特征、细菌群落多样性和演替方面的作用和影响。结果显示,添加绿茶可有效提升大曲群落多样性,并提高大曲糖化力、水分含量和酸度,但茶叶添加比例与群落多样性的升高不呈比例关系,各类曲中特有的群落系统进化结构是影响大曲理化特征的主要因素。发酵过程中,4类曲在中挺期开始出现演替分化,并至发酵结束形成各自独特的群落结构。变形杆菌门、厚壁菌门、拟杆菌门和放线菌门对4类曲群落演替存在不同程度影响,进而驱动各类曲出现不同的理化特征,其中Pseudomonas(假单胞菌属)是原曲和10%添茶曲的重要贡献菌群,乳酸菌Weissella(魏斯氏菌)和Pediococcus(片球菌)是20%添茶曲的重要贡献菌群,Bacillus(芽孢杆菌)是30%添茶曲的重要贡献菌群。本研究结果可为添茶曲的工艺优化和多原料制曲提供理论基础,对于大曲制备工艺和茶叶应用具有一定的指导意义。

建立了一种以面心立方三维光子晶体为基础的有限元预测模型,研究了纳米粒子折射率、溶剂折射率、粒子直径、粒子间距等参数对反射光谱的影响。根据预测结果制备了优化尺寸的Fe_(3)O_(4)@SiO_(2)纳米粒子电调谐器件。结果表明,有限元模型预测的反射光谱中心波长在680 nm至455 nm范围内移动,与制备器件的测试光谱匹配性良好。与解析预测模型相比,建立的三维有限元预测模型得到的反射光谱中心波长的预测结果准确性更高。对于非核壳结构,两种模型的预测误差范围分别为0.49%~1.70%、0.82%~1.49%,表现相当;对于核壳结构,两种模型的预测误差范围分别为3.51%~6.11%、0.28%~1.34%。本文建立的三维有限元模型将预测误差典型值降低为原来的1/5.9。所提模型可用于准确预测胶体体系下自组装光子晶体反射光谱的动态调谐能力,弥补了解析预测模型在核壳结构光子晶体预测准确性方面的不足,可指导粒子材料参数和结构参数设计,以及可调谐范围的优化区间筛选。对反射光谱幅值和谱宽预测准确性的提升需进一步考虑短程有序结构等随机微扰特性的影响。

在图像处理领域中,三维块匹配算法(BM3D)算法结合了空间域与频率域的相关特性,是当前图像去噪效果最好的算法之一。由于该算法存在计算耗时长、相似块提取不够准确、分割块内分布不同的相似特征无法提取等问题,论文提出基于Radon变换进行图像信息降维,并通过求解降维函数的方差值、以及方差最大值坐标定位进行相似块信息的判断,再计算各相似块相对参考块的像素均值比例,并放缩再用于去噪。实验结果显示,优化算法去噪图像相较于原算法去噪图像运行时间减短,图像质量提升。

Journal of Harbin Institute of Technology(New Series) 2016年第2期23卷 79-86页

作者： Huijuan Ye Hao Zhou xinye wang Department of Weaponry Engineering Naval University of Engineering Ministry of Science Research Naval University of Engineering

In order to study the underwater trajectory of the non-powered vehicle discharged from the broadside of the underwater platform,the simulation on the ascent process of non-powered vehicle was realized based on the mathematical model including the movement of the vehicle on the slope plate and in the seawater,the air chamber underwater working process etc. The simulation results show that the outlet speed and attitude of the vehicle meet the requirements of missile launching,the non-powered vehicle discharged from the broadside of the underwater platform is feasible. The simulation results with varying parameters show that the negative buoyancy of the vehicle imposes great impacts on the security of its discharge and the floating process,and the vehicle discharge depth is proportional to the floating time. The models and simulation result can be used in further research on the broadside discharging technology of the underwater platform.

谷赝自旋是构筑光学拓扑绝缘体的重要手段,其性质决定了光波拓扑传输特性。双波段能谷结构为同时调控多波段范围内的光波提供了重要平台。构筑了具有双波段能谷结构的光子晶体超胞,研究了zigzag型和armchair型界面在两个波段内拓扑边界态的传输特性及鲁棒性。结果表明:对于zigzag型界面,对称型界面与反对称型界面的光波传输特性差异显著,对称型界面允许平面波传输而反对称型界面大幅抑制平面波传输;而对于armchair型界面,对称型界面与反对称型界面的光波传输未表现出差异性。对于允许平面波传输的界面,无论是zigzag型还是armchair型界面均对杂质、缺陷、尖锐拐角等具有良好的鲁棒性。双波段拓扑边界态传输特性的系统性研究对于拓展光学拓扑绝缘体的应用空间具有重要价值。
