Abstract: With the research of association rules comprehensive evaluation, this article proposes a books recommended model based on the factors of Support, Confidence, Jaccard Interestingness, Attraction and Profit, and it is also oriented to online bookstores and digital libraries. At the same time, this article determines the weights of the factors in the model by the entropy method and the relative comparison method, and research on the algorithm of the model. Finally, it verifies the function of the model by the developed online bookstore system. The running results of the online bookstore system show that the model can provide the recommended book for users excellently.

Abstract: 具有良好性质的伪随机序列在信息安全与通信中有广泛的应用。根据广义分圆定义构造了一类周期为pn+1的几乎平衡的6阶广义分圆三元序列利用经典的6阶分圆数和部分指数和进一步计算了该序列的自相关值和线性复杂度。结果表明该序列有较好的线性复杂度。
Pseudorandom sequences with good properties have wide application in information security and communications et al. This paper construct an almost balanced generalized cyclotomic ternary sequence with period pn+1 based on the definition of generalized cyclotomic. Further, the autocorrelation values and linear complexity of this sequence are calculated. The method are based on using the classical cyclotomic numbers of order six and the values of partial exponential sums of cyclotomic class of order six over an extension field of GF(3). Results show that this sequence possesses good linear complexity.

Abstract: 利用1998和1999年引进的海湾扇贝(Argopectenirradiansirradians)原种F1进行了连续2a的原种保持实验,包括实验性及生产性两种规模,并用所得原种F3与对照群体进行比较,以探讨在国内进行原种保持的技术措施。2000年,实验性原种制备共培育出M贝(来源于Massachusetts州)原种F2330kg,V贝(来源于Virginia州)原种F2320kg,生产性原种制备共培育出原种F255000kg。2001年,实验性原种制备共培育出M贝原种F3和V贝原种F3均为280kg,生产性原种制备共培育出原种F315000kg,原种F3的肉柱得率(15.42%)明显高于对照组(13.16%),依然保持了引进群体肉柱得率高的特性,因此在国内进行原种保持是可行的。
碎屑岩-碳酸盐岩混合地层沉积特征与演化-以神木气田太原组为例

地质学报 , 2011,
Abstract: 鄂尔多斯盆地东缘的神木气田太原组为特征性的碎屑岩与碳酸盐岩互层含煤岩系。近期天然气勘探证实其具有良好的开发潜力。为指导神木气田太原组开发和盆地太原组储层勘探,根据测井、录井、常规薄片、铸体薄片、物性和粒度资料,结合岩心描述,研究了神木气田太原组地层组合、沉积特征、沉积环境演化、砂体宽度以及沉积相对储层控制作用。太原组地层发育了碎屑岩型、灰岩型和互层型三种组合。地层颜色、粒度、成分、结构、沉积构造、岩石相、测井相、含有物以及沉积序列特征反映其为潮控三角洲与低能碳酸盐台地沉积,主要发育三角洲平原分流河道、分流间洼地微相,三角洲前缘远砂坝、分流间湾微相,以及碳酸盐灰坪、灰泥坪微相。太原组下部(太2段)以三角洲平原沉积为主,分流河道砂体发育,但宽度较窄(7.1-131.9m),上部太一段为三角洲前缘与碳酸盐潮坪沉积,反映其经历了一个沉积水体总体逐渐加深的海侵过程和/或碎屑供应逐渐减少的沉积过程,而太一段碎屑岩与灰岩的互层沉积则反映了太原组晚期沉积水体的振荡性加深→变浅和/或陆源碎屑供应的周期性缺乏。储层主要发育在太二段高能量的三角洲平原分流河道中、粗砂岩中。
农村土地承包经营权抵押贷款供给效果评估――基于农户收入差距的视角
?|,罗剑
南京农业大学学报(社会科学版) , 2015,
Abstract: 本文运用有序Probit模型从农户收入差距视角评价2013―2014年宁夏农村土地承包经营权抵押贷款供给效果。研究发现,农户对农村土地承包经营权抵押贷款供给效果总体评价较高;整体来看,农户对抵押贷款政策的了解程度、参与意愿、贷款资金预期满足程度、资金满足度、贷款资金对家庭帮助、贷款流程、贷款估价等是决定农户满意度评价的主要因素;从农户分组情况来看,影响不同收入农户对贷款供给效果满意度的因素也不尽相同。基于研究结论,提出进一步拓宽抵押担保物范围和模式,加大农村土地承包经营权抵押贷款业务的宣传力度,开展农户贷款流程再造,完善利率定价机制,依据不同贷款对象和用途划分贷款额度和利率水平,不断提高服务质量、改进服务方式,提升客户体验等建议。

中国古亚洲域沉积盆地火山岩油气藏储层特征比较及其差异分析
杨明慧,
地质学报 , 2012,
Abstract: 在中国古亚洲域沉积盆地火山岩储层母岩年代和岩性、储集空间类型以及火山岩岩相综合分析的基础上,探讨了火山岩油气藏的储层特征及其差异性。研究表明,中国古亚洲域火山岩储层的母岩发育年代西早东晚,西部的准噶尔、三塘湖和吐哈盆地发育晚古生代海相、海陆交互相的中基性安山岩、玄武岩及火山碎屑岩;东部的松辽、二连和海拉尔盆地发育中生代陆相中酸性流纹岩、安山岩。火山岩原生储集空间包括气孔、孔洞以及冷凝收缩裂缝等;次生储集空间包括各种溶蚀孔及构造裂缝、风化裂缝等。火山岩岩相可分喷出相、火山通道相、次火山相和火山沉积相。其中中基性岩类多以溢流相开始,相序类型为溢流相、爆发相/火山沉积相;中酸性岩类多以爆发相或火山通道相发端,主要相序为爆发相、溢流相/侵出相。溢流相一般发育原生气孔、构造缝;爆发相多为粒间孔,而侵出相以角砾间孔和原生裂缝为主。火山岩储层的差异受多因素影响,包括岩性岩相、喷发环境以及后期构造、成岩作用等。前者奠定火山岩储层形成与分布的基础和储集空间的发育程度;后者则改造储层的储渗性能。

基于蛛网原理的协同创新过程研究
?遐,
科技进步与对策 , 2014, DOI: 10.6049/kjjbydc.201410x091
Abstract: 协同创新过程是由协同创新主体间的相互作用推动的。不同的协同创新主体有着不同的目标,企业看重收益,科研单位看重研究成果,这导致了它们在协同创新过程中的决策方式不同。借鉴蛛网原理的动态均衡分析,解释了企业与科研单位决策变动互相影响的过程和结果。在没有外部干涉时,不同协同创新目标的动态均衡不同。对于可以自动实现均衡的协同创新目标,政府是否干预取决于其政策方向。协同创新均衡模型创新主体蛛网原理
