Since 1980s, along with general trend of development of comprehensive mechanization in coal mine, concentrated mining production and raising capacity of single coal face, the mining geology was demanded to meet higher and higher requirements of PE ( precise exploration). 随着煤矿综合机械化开采、实行矿井集中生产、提高回采面单产效率的发展,对矿井地质工作提出了愈来愈高的要求。
The main reasons of concentrated coarse sediment of the river is severe erosive sediment yield, strong sediment transporting capacity and high sediment concentration; 侵蚀产沙强烈而粗泥沙集中,输沙能力强,洪水含沙量高,是黄河粗泥沙的集中来源地;
Compared with the traditional concentrated conference bridge, it can reduce the utilization of the trunk channel resource and expand the capacity of the conference bridge in some application case. 提出了分布式会议桥的思路,与传统的集中式会议桥相比,在某些应用场合下可减少电话会议局间信道资源占用量,并可扩展会议桥的容量。
The results show that initial imperfection, disposal manner of concentrated load and system temperature influence the ultimate load-carrying capacity lightly. 分析结果表明:初始缺陷、集中荷载作用方式以及体系温度对结构极限承载力影响不明显;
Obviously, the key points are how to prepare the dispersed, stable and low viscosity SiC concentrated slurry in order to improve the capacity of the casting process in vitrified abrasive product; 显然,本课题的技术关键及难点在于制备分散稳定且固相含量较高、黏度较低的SiC浆料,以解决陶瓷磨具成型工艺性能;
Because of the highly concentrated loading and eccentric loading, it is difficult to predict the failure mode and the ultimate bearing capacity when the thin-walled steel I-girders are subjected to eccentric patch loading. 薄壁工字形钢梁在小片荷载偏心作用下,由于荷载的局部高度集中,再加上本身加载有偏心,其破坏模式和承载力的估计是一个很复杂的问题。
The vertically concentrated load has visible effects on ( ultimate) horizontal bearing capacity and lateral displacement. 垂直集中荷载对框架的水平极限承载力、侧移有明显影响;
Root amount was bigger and concentrated in the upper layer of soil at filling stage, so the capacity of nutrient absorption increased in raised bed-cultivated rice. 总根量增加,上层根量所占比重大,养分吸收能力增强。
Its channels 'impact characteristics are the concentrated market areas, limited supply capacity of middlemen and distributors, limited financing capacity, old organizational system and the lack of marketing talents with comprehensive quality. 岳麓书社渠道影响特征为市场区域较集中,中间商、分销商供应能力有限,企业融资能力有限,组织制度陈旧,缺少综合素质的营销人才。
The actual competitive capability of each commercial bank is the key for winning the battle without fire in which the business performance is the concentrated expression of its competitive capacity. 商业银行在这场没有硝烟的战争中能否胜出,关键还是看各家商业银行的具体竞争力,而其中商业银行的经营绩效又是其竞争力的集中表现。
This paper is concentrated on the bearing capacity and construction control theory of concrete filled steel tubular ( CFST) long-span arch bridges. 本文主要研究大跨度钢管混凝土拱桥的承载能力与施工控制理论。
The current situation, elective courses in aerobics is not a lot of research papers, showing a balanced development trend of slight, mainly concentrated in teaching, training, basic theory and function of bodybuilding, while the capacity to foster innovative research negligible. 目前来看,健美操选修课方面的科研论文数量并不多,呈平衡略升的发展趋势,内容主要集中在教学、训练基础理论和健身健美功能研究,而对培养创新能力方面的研究微乎其微。
Currently, the study of DNA computing and P system is mostly concentrated in the feasibility and capacity of computing. 目前关于DNA计算以及P系统的研究主要集中在计算的能行性与计算能力方面,本文则致力于基本的算术运算研究。
