为了解城市生活固体废物焚烧过程中主要元素的迁移分布规律,分析焚烧炉运行过程中出现结渣现象的原因,并考察掺烧污泥和造纸废渣可能对灰渣特性造成的影响,本研究对焚烧炉中底渣和沿烟气流程各处飞灰的元素组成、物相组成以及微观形貌进行分析。结果表明:低挥发性元素Si、Al、Fe主要以氧化物的形式存在于底渣中,其含量分别为16.64%、4.26%、4.08%,沿烟气流向在飞灰中含量逐渐降低,布袋除尘器飞灰中其含量分别为1.15%、0.37%、0.31%;高挥发性元素Na、K、Cl在布袋除尘飞灰中的含量分别高出底渣5.53%、4.73%、23.74%,其主要以NaCl、KCl蒸汽的形式进入烟气中,并随着温度的降低逐渐冷凝到受热面和飞灰表面,沿着烟气流向,在飞灰中质量分数逐渐增加,分别从2.66 wt%升至8.19 wt%,1.77 wt%升至6.50 wt%,2.44 wt%升至26.18 wt%;底渣中NaAlSi_(3)O_(8)、KAlSi_(3)O_(8)、Ca_(2)Al_(2)SiO_(7)可能导致炉排发生结渣熔融现象,此外,二三烟道飞灰含有的CaSO_(4)、Ca_(2)Al_(2)SiO_(7)和水平烟道飞灰中的NaCl、KCl、CaSO_(4)容易导致受热面发生结渣现象;掺烧污泥和造纸废渣不会对底渣和飞灰的物相组成造成大的改变,但是高温过热器和反应塔飞灰NaCl、KCl、CaSO_(4)含量增加,可能加重烟道内结渣和腐蚀现象。

In the present study, laser alloying of electroless Nie P coating on aluminum substrate was conducted using Nd：YAG pulsed laser under the condition of 5.36 109W/m2 in power density and 3.0 mm/s in scanning speed. The rapidly solidified microstructure in the alloyed layer was studied. The results showed that the alloying element distributed in the alloyed layer is inhomogeneous. The dendrite containing relatively high Ni was identified as Al3Ni phase and the areas between the dendrites are rich in Al content. Featureless with cell structure in Al-rich areas was firstly displayed by z-contrast image. Amorphous structure was revealed to exist in Al-rich areas.

At present, 5G network technology is being applied to various social network modes, and it can provide technical and traffic support for social networks. Potential friendship discovery technology in 5G-enabled social networks is beneficial for users to make potential friends and expand their range of activities and social hierarchy, which is highly sought after in today's social networks and has great economic and application value. However, the sparsity of the dominant user association dataset in 5G-enabled social networks and the limitations of traditional collaborative filtering algorithms are two major challenges for the friend recommendation problem. Therefore, in order to overcome these problems regarding previous models, we propose a Hybrid Ensemble Multiple Collaborative Filtering Model (HEMCF) for discovering potential buddy relationships. The HEMCF model draws on a special autoencoder method that can effectively exploit the association matrix between friends and additional information to extract a hidden representation of users containing global structural information. Then, it uses the random walk-based graph embedding algorithm DeepWalk to extract another hidden representation of users in the buddy network containing local structural information. Finally, in the output module, the HEMCF model stacks and multiplies the two types of hidden representations of users to ensure that the information mentioned above is concentrated in the final output to generate the final prediction value. The magnitude of the prediction value represents the probability of the users being friends, with larger values representing a high probability of the two users being friends, and vice versa. Experimental results show that the proposed method boosts the accuracy of the relationship prediction over baselines on 3 real-world public datasets dramatically.

苹果斑点落叶病菌是苹果生产过程中常见的病害,严重危害苹果农作物的产量.脂肽作为一种主要来源于微生物次生代谢产物的抗菌剂,具有广谱抑菌、低耐药性、安全低毒等优势.本研究发现,解淀粉芽孢杆菌wxy-b3产生的脂肽类物质能够抑制苹果斑点落叶病菌的生长,对苹果斑点落叶病菌的最小抑菌浓度为16 mg/mL,此浓度可造成该病原菌细胞膜电位超极化、线粒体膜电位去极化、大分子蛋白质和核酸泄露,以及胞内活性氧和丙二醛含量分别累积增加0.33倍和5.44倍,并通过扫描电镜进一步观察到MIC处理组的细胞形态起皱、细胞膜破损.上述结果表明,脂肽可能通过破坏细胞膜系统,导致细胞形态发生变化,细胞膜破裂,改变细胞膜通透性来达到抑菌效果.该研究将为脂肽作为抑制苹果斑点落叶病菌的抗菌剂奠定理论基础.

水泥剂量是控制流态固化土强度的关键指标,工程中多采用EDTA滴定法进行检测,但流态固化土制备过程中含水量与水泥水化时间偏差会导致检测数据失真.研究了EDTA二钠标准溶液消耗量随水泥剂量、含水量和水化时间三因素的变化规律;基于回归正交试验,开展了多因素及交互影响的主次关系分析与显著性评价,建立了考虑三因素综合影响的EDTA二钠标准溶液消耗量回归方程.试验表明,EDTA二钠标准溶液消耗量与水泥剂量近似呈线性正相关,随含水量增大或水化时间延长近似线性降低;影响因素主次顺序为水泥剂量、含水量、水化时间,交互作用不显著;因素水平在回归正交试验组范围内,回归方程计算值误差低于2.40%;含水量或水化时间分别偏差2.9%、86min,将造成水泥剂量检测值增减约0.5%.研究成果可为完善流态固化土水泥剂量检测技术提供参考.

不同于政治权力,资本权力是内在于市民社会的权力形式。资本权力并非天然存在,而是在社会历史的演进中形成。随着交换关系的日益频繁和扩展,财富从支配劳动产品到支配劳动力本身,劳动力成为商品是货币权力上升为资本权力的关键一环。资本统治着商品生产过程使劳动绝对从属于资本,工场手工业时代,工场内部的分工导致工人片面化、畸形化,工人的个体劳动依附于庞大的分工体系。机器大工业时代,自动化的机器体系升格为生产过程的“主体”并成为镇压工人反抗的强大武器,科学为资本服务变成统治活劳动的异己权力。围绕分工、机器、科学建立起的现代工厂制度对工人进行极致地剥削,工厂被称作“温和的监狱”。资本将个人劳动社会化地组织起来,极大地促进了生产力的发展,与此同时,资本对活劳动的统治形式也变得愈加抽象。扬弃资本权力是共产主义的本质要求,智能化的机器体系将会是实现人的解放的重要物质力量。
