将可再生能源发电丰沛期的电量用于电解水制氢并存储被认为是应对可再生能源发电不稳定缺憾的重要解决方案之一.氢气的比能在所有的燃料中最高,但其能量密度较低,存储一直是世界性难题,大量存储则更加困难.随着氢气存贮技术的不断进步,地下存储或地质存储被视为大规模储氢技术最具可行性的发展方向.

Soil shrinkage is an important factor in slope destabilization in granitic areas,which is also one of the most important conditions for the formation of permanent gullies.This study explored the effect of soil shrinkage on permanent gullies,and Benggang e
Rosa arabica Crép.is a perennial shrub belonging to the family Rosaceae.It is endemic to the high mountain area of St.Catherine Protected Area(SCPA)in southern Sinai,Egypt,and is listed as one of the most 100 threatened plants in the world.Recently,it has
为了解决现有激光打标系统出现的异形打标困难、字符图形不清晰、模糊等问题,搭建了一套多异形三维激光打标系统,此系统由硬件和软件组成.硬件部分在平面打标平台基础上引入分段扩展轴、旋转扩展轴,利用红外对焦定位系统,实现三轴联动打标;软件部分针对激光打标机无法在大幅面、异形等工件上自动打标雕刻的缺陷,设计了一种改进的标刻处理软件,并融合多电机控制实现平面与斜面一次性正焦和离焦打标功能.本系统可以实现斜面、段差、圆柱、圆锥、球面以及拉伸曲面等多种3D打标模式的功能.实验测试结果表明,该系统在多种异形工件上实现了无误
Biocrusts affect soil detachment through above-ground(top crust\'s surface covering)and below-ground(sub-crust\'s binding and bonding,B&B)effects,which might vary with biocrust development or coverage.However,these effects in humid climates are still
前陆盆地以蕴藏构造油气藏为主,岩性地层油气藏在以往被认为难以形成规模资源量.以库车坳陷东部中生界为例,在大量露头、钻井、地震和测井资料叠合分析的基础上,分析出吐格尔明大型背斜构造为古新世和上新世继承性基底冲断作用的产物,其变形主压应力场的方位为NNE--SSW向;依奇克里克背斜构造为基底卷入的冲断构造,其褶皱南翼相对简单,为迪北斜坡带,北翼呈低角度北倾,变形主压应力场的方位为NNW--SSE向.库车坳陷东部中—下侏罗统和上三叠统发育巨厚层煤系腐殖型和暗色泥岩腐泥型烃源岩,沉积中心分布在库车河地区、迪北地区
Rapid climate change has provided the opportunity for many species to learn to adapt fast enough to modify their range distribution.The positive and negative responses of the species in terms of distribution are related to parameters such as kind of speci
Accumulation and losses of soil organic carbon (SOC),total nitrogen (TN) and sulphur (S)influence food security and global warming.Therefore,their spatial distribution and variability at regional scale,and their relation to topographical variables are of
建立了制动盘有限元模型,仿真得到制动盘前五阶弹性模态;对制动盘进行模态试验,阐述了制动盘模态试验的参数选择、测点布置、模态置信度判断准则,并通过综合频率响应函数和模态置信准则验证了试验结果的可靠性;仿真与试验得到的制动盘模态振型、模态频率等结果误差很小,二者基本一致.结果表明,所建立的制动盘有限元模型可用于约束状态下制动盘振动和噪声性能的预测.
The rheological behaviors of highly concentrated fine particle suspensions(clay-silt-water mixtures)and coarse particle suspensions(coarse particles within a fine particle suspension)were investigated in this study.Experimental results demonstrated that t
The Central Himalayan region is vulnerable to the adverse effects of climate change and characterized by regional climatic conditions.The livelihood of the mountain communities across the Himalaya is at risk owing to the consequences of variable precipita
