文章通过大型有限元分析软件A BA QU S对5片不同轴压比下钢筋混凝土剪力墙模型进行循环往复加载,通过变换轴压比分析对剪力墙抗震性能的影响.分析结果表明:无论轴压比如何变化,剪力墙的损伤均始于墙底端部,轴压比在0.1～0.3时,剪力墙呈现弯曲破坏,轴压比在0.4～0.5时,剪力墙呈现出斜压破坏,随着轴压比的提高,剪力墙抗剪承载力增大,而其塑性变形能力在减弱,剪力墙抗侧承载力存在阈值,且剪力墙出现损伤后,抗剪承载力下降较快,刚度退化速率下降速率较快.

Year 2021 is special.It sees the renaissance of concept of phase and the birth of a phase theory for matters much beyond complex numbers and single-input single-output(SISO)linear time-invariant(LTI)systems while we celebrate the 60th birthday of Lei Guo,
利用5年的欧洲中心集合预报产品数据,通过格点插值和中国气象局评分检验方法,对西藏全区的主要站点及拉萨的首场降雪和极端降雨个例作了检验评估,得出了可用于实际预报业务的参考指标:最小值产品全区晴雨准确率超过73％,察隅的中雨和日喀则的大雨最大值产品几乎无漏报,对帕里预报明显偏大,嘉黎明显偏小.拉萨第一场雪的中大雪过程,控制预报,平均数和中位数有较好的参考价值,对于小雪量级及以上过程提前一天有预报提示,拉萨强降雨的预报和实况出现时段较一致,但预报量偏小10倍以上,无极端天气出现的预报提示.
Nowadays the semi-tensor product(STP)approach to finite games has become a promising new direction.This paper provides a comprehensive survey on this prosperous field.After a brief introduction for STP and finite(networked)games,a description for the prin
This is an overview paper on the relationship between risk-averse designs based on expo-nential loss functions with or without an additional unknown(adversarial)term and some classes of stochastic games.In particular,the paper discusses the equivalences b
提高科技创新能力是产业实现高质量发展的动力源泉,对于西藏决胜全面建成小康社会具有重要意义.文章根据西藏的科技创新发展情况,发现西藏技术创新发展能力较难支撑区域产业发展的需要.因此从资源配置效率的视角提高西藏科技创新能力,进而提出推动西藏产业高质量发展提出相应的政策措施.
What makes biological systems different from man-made systems?One distinction is explored in this paper:Biological systems achieve reliable functions through randomness,i.e.,by both mitigating and exploiting the effects of randomness.The fundamental reaso
将从西藏地区分离纯化获得的6株木质纤维素分解菌作为复合菌剂接种入以牛粪和青稞秸秆为原料的堆肥体系中,在高原条件下考察外加木质纤维素分解菌对堆肥体系的促进作用.结果表明,与对照组相比接菌处理延长了堆肥的高温期,使高温期增加了4d,并提高了10.5℃的堆肥峰值温度.此外,接菌处理对堆肥体系的pH值、电导率、含水率、可溶性化学需氧量、挥发性固体有机物、氨氮含量、发芽指数以及纤维素酶活性都有不同程度的影响,且各类指标均满足堆肥腐熟的要求.接种木质纤维素分解菌提高了最终堆肥产品的腐殖化水平和腐熟度,有益于高原条件下
This work is concerned with controlled stochastic Kolmogorov systems.Such systems have received much attention recently owing to the wide range of applications in biology and ecology.Starting with the basic premise that the underlying system has an optima
桦褐孔菌是一种珍惜食药用,其多糖在预防、抑制或治疗疾病方面起着重要作用.文章通过在西藏桦褐孔菌产地米林、波密和吉隆等地对西藏桦褐孔菌子实体的采集、收集、分离并纯化培养得到3株桦褐孔菌菌株(D ZCR 161、G P2018、XA G 2403,其中XA G 2403保藏于西藏种质在资源库,菌种保藏号为A F0002051XA G 2403),通过其D NA序列分析进行分子鉴定,确定3株菌种都是桦褐孔菌;通过对3株菌株液体发酵,以相同条件下每个菌株产胞内、胞外多糖的总量作为评价指标,初步筛选出由西藏种质资源
In social networks where individuals discuss opinions on a sequence of topics,the self-confidence an individual exercises in relation to one topic,as measured by the weighting given to their own opinion as against the opinion of all others,can vary in the
