1)  5 F7
5'F7
1.
Aim:To investigate the distribution of R353Q,5 F7,IVS7 polymorphisms of the FⅦ gene in Chinese Han population.
方法:利用PCR-RFLP技术,分析560名河南汉族正常人FⅦ基因R353Q、5′F7和IVS7多态性分布情况。
2)  F7 fault
F7断层
1.
The Elastic-visco Displacement Back Analysis of Wushaoling Tunnel F7 fault;
乌鞘岭隧道F7断层的黏弹性位移反演分析
2.
This displacement of the rock wall is not convergence in a long time after excavating in F7 fault of the Wushaoling tunnel,and the time for lining executed can not meet the request of "The Code for Design of Railway Tunnel ".
乌鞘岭特长隧道11#斜井处正洞在穿越F7断层时,由于隧道埋深大,断层岩体破碎,岩体完整性差,围岩自稳能力弱,受挤压影响等,开挖后围岩变形长时间不收敛,50d后的变形仍有2—4mm/d,累计最大变形量已超过60cm,部分地段严重侵限,不能满足《铁路隧道设计规范》关于二次衬砌施做的规定。
3.
Combined with the measurement data from Wushaoling tunnel traversing the F7 fault,and taking the surround rock as isotropic body,the initial ground stress is postulated to be in well-proportioned distribution,the tri-element model was utilized.
结合乌鞘岭隧道穿越F7断层所取得的量测资料,将计算区域内的岩石视为均质各向同性体,初始地应力假设成均匀分布,采用三单元模型和工程实践及三维有限元分析结果,围岩变形规律通过引入位移释放系数考虑测点的时空效应,对有限元黏弹性问题进行优化反演分析,得出围岩区域内的水平侧压力系数和所使用模型中的弹性模量和黏滞系数,为挤压性断层中隧道的支护设计、施工组织提供可靠的依据。
3)  F7 gene
F7基因
4)  Anti-disease grass F7
抗病草鱼F7
1.
Random amplified polymorphic DNA(RAPD) technique was applied to study the genetic relationships of Anti-disease grass F7(83-2 strain F2) and Ctenopharyngoden idella,Cyprinus carpio red.
用RAPD技术对抗病草鱼F7(83-2系鱼F2)与原代亲本草鱼、兴国红鲤进行亲缘关系的研究。
5)  ZSM-5 zeolite
ZSM-5
1.
Controlled synthesis of larger crystal ZSM-5 zeolites using different templates;
采用不同模板剂控制合成较大晶粒的ZSM-5分子筛
2.
The effects of the reaction temperature, space velocity, and benzene/propane molar ratio on the alkylation of propane with benzene over Pt/HZSM-5 zeolite.
结果表明,Pt/HZSM-5具有较好的催化性能。
3.
β zeolites with different silica/alumina ratio and commercial promoters prepared from ZSM-5 zeolite were tested on FFB and ACE FCC apparatus,using heavy oil(70% Xinjiang paraffin oil and 30% Xinjiang residue) as the feed.
以重油(70%新疆蜡油掺和30%新疆渣油)为原料,在FFB和ACE装置上对3种不同硅铝质量比β分子筛和工业应用的ZSM-5分子筛制备的催化裂化助剂的反应性能进行对比评价。
