然而,氢气储运仍面临较大的成本和安全难题,有机液体储氢化合物(LOHCs )储放氢技术以其储氢密度较高、储存条件温和、运输方便等优势成为氢气储运可供选择的技术之一。

相比稠环芳烃类化合物,含氮有机储氢化合物具有更温和的催化加氢和脱氢条件,可有效提高储放氢鲁棒性和反应能效。

基于此,本文系统综述了含氮有机储氢化合物加氢及脱氢反应研究进展,阐述了两类反应的路径和催化作用机制,从催化剂活性中心和载体、双金属协同效应、反应条件、催化剂稳定性等方面系统分析了加氢/脱氢催化剂,并详细总结了基于连串反应、反应网络等模型的反应动力学。

介绍了含氮有机储氢化合物储氢技术目前面临的挑战并提出未来的研究思路及展望。

但是该技术仍存在较多问题,应在有机储氢化合物配方体系、储放氢连续反应系统、催化剂设计与制备、催化剂构效关系、精准反应动力学和全面理化性质数据库等方面进行深入研究。

However,hydrogen storage and transportation are still facing problems of high cost and safety. The hydrogen storage and release technology based on liquid organic hydrogen carriers (LOHCs) has become one of the available technologies with its advantages of relatively high hydrogen storage density, mild storage conditions and convenient transportation. Compared with polycyclic aromatic hydrocarbons, nitrogen-containing LOHCs is milder in catalytic hydrogenation and dehydrogenation, which can effectively improve the robustness of hydrogen storage and release and the reaction efficiency.

助溶剂法生长碳化硅晶体

助溶剂法生长碳化硅晶体

助溶剂法生长碳化硅晶体英文回答:Growing silicon carbide crystals using the solvent-assisted method is a common technique in crystal growth research. This method involves the use of a solvent to enhance the solubility of the silicon and carbon precursors, allowing for the controlled growth of high-quality crystals.In this process, a solvent is chosen that has a high solubility for both the silicon and carbon precursors. Common solvents used include toluene, xylene, and acetone. The solvent is then mixed with the precursors, such as silicon tetrachloride (SiCl4) and a carbon source like propane or acetylene.The solvent-assisted method offers several advantages over other crystal growth techniques. Firstly, it allowsfor better control over the crystal growth process,resulting in higher quality crystals with fewer defects.The solvent acts as a buffer, preventing the formation of impurities and ensuring the crystal grows in a controlled manner.Additionally, the solvent-assisted method enables the growth of larger crystals compared to other methods. The enhanced solubility provided by the solvent allows for the incorporation of more silicon and carbon atoms into the crystal lattice, leading to larger crystal sizes.To illustrate this, let's consider an analogy. Imagine you are baking a cake. The solvent in this case is like the cake batter, which helps to dissolve and evenly distribute the ingredients (silicon and carbon precursors) throughout the mixture. Without the batter, the ingredients may clump together or not mix properly, resulting in an uneven and poorly formed cake (crystal).Now, let's move on to the 中文回答:助溶剂法生长碳化硅晶体是晶体生长研究中常用的技术。

Structural features, properties, and possible applications of mesocrystals are summarized in this paper. Due to their unique structural features and the resulting physical and physicochemical properties, mesocrystals are expected to play a significant role in improving the performance of materials in many applications. These are as diverse as heterogeneous photocatalysts, electrodes, optoelectronics, biomedical materials, hard templates, and lightweight structural materials.In the past 6 years, more and more attention has been paid to mesocrystalline materials. An increasing number of papers have been published in the literature. Most of these focused on the characterization of structures and the investigation of formation mechanisms. The results indicate that the structure and formation mechanism of a mesocrystal are related to the shape of the nanoparticle, colloidal stabilization, and vectorial long-range interaction potentials. Surface interaction between the nanoparticles plays a critical role during the formation process of a mesocrystal and may be responsible for the formation of external faces. The reason for the remarkably (almost perfectly in some cases) ordered alignment of nanoparticles is still poorly understood. Special emphasis has been placed on the different possible forces that may drive orientation and assembly between nanoparticles.This work describes the real-time and quantitative analysis of calcium phosphate mineralization using a quartz crystalmicrobalance (QCM) sensor and synthetic DNA templates. In typical mineralization studies, static end-point analysis and surface characterization is common, while real-time quantitation focusing on time of nucleation, nucleation rates, time of crystal growth, and growth rates has not been widely explored. A better understanding of these parameters in coordination with structural analysis could aid in the assessment of template molecules and could provide insight into biological and biomimetic mineralization. QCM is a dynamic, real-time analytical technique that can be generalized to a variety of minerals and can be integrated with widely used surface characterization techniques. As a template for mineralization, DNA has only recently been studied, although it has potential as an anionic polynucleotide with unique programmability and structural diversity in folding.Living organisms are well known to exploit the material properties of amorphous and crystalline minerals when building a wide range of organic–inorganic hybrid materials for a variety of purposes, such as navigation, mechanical support, photonics, and protection of the soft parts of the body. The high level of control over the composition, structure, size, and morphology of biominerals results in materials of amazing complexity and fascinating properties that strongly contrast with those of geological minerals and often surpass those of synthetic analogues.[1] It is no surprise, then, that biominerals have intrigued scientists for many decades and served as a source of inspiration in the development of materials with highly controllable and specialized properties. In this Review we aim to provide an overview of the different nature-drawn strategies that have been applied to produce materials for biomedical, industrial,and technological applications. We will first illustrate the diversity of biogenic minerals and their overall properties, and describe the most general approaches used by organisms to produce such materials. We will then discuss several approaches inspired by the mechanisms of biomineralization in nature, and how they can be applied to the synthesis of functional and advanced materials such as bone implants, nanowires, semiconductors, and nanostructured silica. In the final section, we will discuss methods that are necessary to study and visualize the formation of synthetic materials in situ so as to better understand, control, and optimize their synthesis and properties.Nanoparticles with dipole or magnetic moments will create local dipole/magnetic fields and can mutually attract each other in crystallographic register. The same is true for anisotropic particle polarization, where particle surfaces with equal polarizability attract each other by directed van der Waals forces. This concept requires the nucleation of a large number of nanoparticles of about the same size with the requirement of anisotropy along at least one crystallographic axis. This anisotropy can also be inherent to the crystal system as was observed for the case of amino acid crystals or might be induced by selective polyelectrolyte adsorption to expose highly charged faces simultaneously with their oppositely charged counterface. Amino acids are an ideal system for the study of mesocrystal formation since simple pH variation can vary the crystallization path between classical and nonclassical crystallization, the supersaturation, and crystallization speed as demonstrated for DL-alanine. Indeed, very recently, mesocrystals were also observed for the same system by precipitation in water–alcohol systems.。

描写刀鱼 英文作文

描写刀鱼 英文作文

描写刀鱼英文作文The Yangtze River, a lifeline of China, cradles within its depths a treasure,a delicacy so prized that it borders on the mythical - the knife fish. Its slender, silver form, shimmering like a blade under the watery sun, has captivated poetsand gourmands for centuries, its name whispered with reverence and longing. Butthe knife fish is more than just a culinary icon; it is a symbol of the river's fragile ecosystem, a testament to the delicate balance between nature and human intervention. The knife fish, or Coilia ectenes, is an anadromous fish, spending most of its life in the ocean but returning to freshwater to spawn. It is during this arduous journey upstream, against the mighty currents of the Yangtze, thatthe fish undergoes a remarkable transformation. Its body, lean and muscular from battling the ocean tides, fattens, its flesh becoming rich with a unique, buttery flavor. This transformation coincides with the arrival of spring, and for generations, the appearance of knife fish in the markets has been a harbinger of the season's bounty. The allure of the knife fish lies not only in its taste but also in its ephemeral nature. Its season is fleeting, lasting only a few precious weeks in spring. This short window of availability, coupled with its delicate texture and exquisite flavor, has made it a highly sought-after delicacy, a prize to be savored and celebrated. In the bustling markets of Shanghai and surrounding cities, the arrival of the knife fish triggers a frenzy of activity, with customers vying for the freshest catch. Prices soar, and the fish become a status symbol, a testament to discerning palates and extravagant lifestyles. Traditionally, the knife fish is steamed whole, its delicate bones softening to become almost edible. The simplicity of this preparation allows the pure, clean flavor of the fish to shine, a testament to the belief that the best ingredients need little embellishment. Served with a drizzle of soy sauce and a scattering of spring onions, the dish is a symphony of textures and flavors, a celebration ofthe ephemeral bounty of the river. However, the reverence for the knife fish is tinged with a growing sense of urgency. Overfishing, coupled with the damming of the Yangtze River and pollution, has drastically reduced the knife fish population. The once abundant schools, shimmering like silver ribbons in the river's depths, have dwindled, their numbers a shadow of their former glory. The soaring prices,once a sign of the fish's desirability, now reflect its increasing scarcity, a grim reminder of the fragility of this iconic species. The plight of the knife fish serves as a stark reminder of the interconnectedness of ecosystems and the impact of human actions on the natural world. As the Yangtze River, the lifeblood of China, faces increasing pressure from development and pollution, the fate of the knife fish hangs in the balance. Its decline is a warning, a plea for sustainable practices and a renewed commitment to safeguarding the treasures of this mighty river. The hope remains that the iconic knife fish, a symbol of spring and a testament to the delicate balance of nature, will not become a mere legend, a ghost of the Yangtze's past.。

黄海生态系统高营养层次生物群落功能群及其主要种类张波;唐启升;金显仕【摘要】根据2000年秋季和2001年春季在黄海的两次大面调查,选取生物量占总生物量90%的生物种类为研究对象,分析了黄海生态系统以及3个生态区(冷水团海域、近岸水域和黄海南部水域)春秋两季高营养层次生物群落的功能群组成及其主要种类.结果表明,黄海生态系统高营养层次生物群落包括6个功能群.按生物量排序为:浮游生物食性功能群、底栖动物食性功能群、鱼食性功能群、虾食性功能群、广食性功能群和虾/鱼食性功能群,各功能群营养级范围分别为3.22~3.35、3.30~3.46、4.04~4.50、3.80~4.00、3.38~3.79和4.01.黄海生态系统的主要功能群为浮游生物食性功能群和底栖动物食性功能群,占总生物量的79.6%;主要种类包括13种:小黄鱼、鳀、细巧仿对虾、银鲳、细点圆趾蟹、带鱼、黑鳃梅童、黄鲫、龙头鱼、双斑蟳、细纹狮子鱼、三疣梭子蟹和凤鲚,约占总生物量的70.6%.从不同季节看,春季黄海不同生态区高营养层次的营养级接近,而秋季差别较大,这主要与生物繁殖和索饵群体组成及摄食习性相关.从不同生态区看,黄海冷水团海域高营养层次生物群落以浮游生物食性功能群为主,受季节变化的影响较小,其高营养层次的营养级接近.黄海近岸水域和黄海南部水域高营养层次生物群落功能群组成受季节的影响较大,秋季的营养级均高于春季的营养级.这表明黄海冷水团海域较近岸水域和南部水域稳定,是黄海的一个典型的生态区域.【期刊名称】《生态学报》【年(卷),期】2009(029)003【总页数】13页(P1099-1111)【关键词】功能群;主要种类;高营养层次;生物群落;黄海生态系统【作者】张波;唐启升;金显仕【作者单位】中国水产科学研究院黄海水产研究所,农业部海洋渔业资源可持续利用重点开放实验室,青岛,266071;中国水产科学研究院黄海水产研究所,农业部海洋渔业资源可持续利用重点开放实验室,青岛,266071;中国水产科学研究院黄海水产研究所,农业部海洋渔业资源可持续利用重点开放实验室,青岛,266071【正文语种】中文【中图分类】Q145;S92.9海洋生态系统中的生物种类繁多,食物关系错综复杂,并易受海洋理化环境变化的影响,但大量研究表明尽管生态系统中生物群落的种类组成会有显著的变化,但食物资源的利用方式,即功能群的组成还是相对稳定的[1]。

群控技术在C油田的应用与认识

群控技术在C油田的应用与认识

从能量角度观察,机械采油井地面系统是由供电系统、采油设备和井口装置组成,其中供电系统主要由变压器向机采井供电,带动抽油机进而带动抽油泵从井下抽汲原油至地面,整个系统属于“一变一井”系统,即一台变压器向一口机械采油井提供能量的系统[1-3]。

理论上讲,“一变一井”系统具有较大的节能潜力。

为进一步降低举升能耗,C 油田在机械采油领域的一个平台的丛式井上试验了群控技术,该技术的实施为机械采油系统的能源节约开辟了新的技术途径。

1技术组成与原理1.1技术组成群控系统应用于丛式机械采油井平台,由一台变压器、一台整流装置、供电线缆、逆变装置、配电箱、电动机、抽油机、井口及井下杆管泵系统组群控技术在C 油田的应用与认识江黎黎(大庆油田有限责任公司第七采油厂)摘要:群控技术采取“一变多井”模式,即一台变压器带动多口机械采油井,同时配备整流装置、逆变装置实现从交流电到直流电,再从直流电到交流电的转换。

选取一个平台的16口井开展了现场试验,对变压器容量、单井控制进行研究与论证,测试结果表明,直流电经过逆变器变成交流电的效率平均可达97.67%,变压器的效率由改造前的97.86%提升至98.71%,提高了0.85%。

应用群控技术后,变压器数量由16台减少为2台,产液单耗由18.24kWh/t 下降到15.34kWh/t,下降了2.9kWh/t。

通过试验与论证,群控技术适用于一个采油平台上多口机械采油井,且变压器与最远端井的距离在1000m 范围内。

长江芜湖江段鱼类多样性及其群落结构的时空格局

长江芜湖江段鱼类多样性及其群落结构的时空格局邓朝阳;朱仁;严云志【摘要】为制定合理的渔业资源保护措施与管理对策,2009年按季度共4次调查了长江芜湖江段鱼类多样性及其群落结构.结果显示:该江段现有鱼类54种,其中以似鳊(Parabramis pekinensis)、油(韰)(Hemiculter bleekeri bleekeri warpacho)、短颌鲚(Coilia brachygnathus Kreyenberg et Pappenheim)、鲫(Carassius auratus)等中小型鱼类为常见种和优势种,表明了该江段的鱼类组成存在明显的小型化特点.长江干流沿岸浅水区的鱼类多样性最高,江心深水区最低,而青弋江支流、漳河支流和漳河河口的居中,青弋江的鱼类种数和个体数都显著低于沿岸浅水区,但漳河的鱼类数量与沿岸浅水区无明显差异.江心深水区的鱼类群落与其它样点明显不同,而青弋江的鱼类群落与沿岸浅水区、漳河及其河口的鱼类群落也存在部分差异.鱼类群落结构的季节动态无显著性.%Identifying the spatial and temporal variations in fish assemblages is basic for fishery resource conservation and management. In this study, fish diversity and their assemblage structures in the Wuhu section of the Yangtze River were investigated seasonally during 2009. A total of 54 fish species were collected, of which the common and dominant species were Pseudobrama simony, Hemiculter bleekeri, Carassius auratus, Coilia brachygnathus, and so on, suggesting the miniaturization of fish species composition in this area. The highest species diversity was observed in the riparian shallow site of the mainstem, while the lowest diversity was in the middle deep site. Fish species and abundance in the Qingyijiang tributary were significantly lower than those in the riparian site of the mainstem, but no significantdifference was observed between the Zhanghe tributary and the riparian site. The assemblage structures in the middle deep site of the mainstem were substantially different from those in other sampling sites, and an obvious separation in assemblage structures was observed between the Qingyijiang tributary and other sites. However, fish diversity and assemblage structures in the Wuhu section did not show significant variations across seasons.【期刊名称】《淡水渔业》【年(卷),期】2013(043)001【总页数】9页(P28-36)【关键词】鱼类多样性;群落结构;时空格局;长江芜湖段【作者】邓朝阳;朱仁;严云志【作者单位】安徽省芜湖市渔业渔政管理中心,安徽芜湖241000;安徽师范大学生命科学学院,安徽芜湖241000;安徽师范大学生命科学学院,安徽芜湖241000【正文语种】中文【中图分类】S932.4近些年来,长江鱼类生态学及其资源保护已引起我国鱼类学家的广泛关注,有关长江鱼类的摄食、生长和繁殖等基础生物学[56]、种群统计学及其资源量[78]、早期资源现状和分布规律[910]、鱼类群落及其资源的分布格局[1113]、鱼类多样性及其资源保护[1]等已得到了较为深入的研究。

研究结果表明:在脱模过程中,通道底部最早与Ni 模芯分离,随后通道肩部开始分离,COC 和PP 脱模速度最快;随着脱模过程的进行,界面相互作用能先增大后逐渐减小,PMMA 的界面相互作用能最大,黏附能最大;在界面相互作用能作用下,聚合物层各部分的运动速度不一致,这是造成通道一定程度拉伸、凹陷和孔隙等变形行为的主要原因;脱模后聚合物整体密度减小和分子链回转半径增大,较好地解释了聚合物整体结构的变化情况。
