浅谈地震科技档案鉴定的意义

地震科技档案鉴定是档案管理部门的一项重要工作。针对地震科技档案鉴定工作的重要意义进行了分析，定期对地震科技档案鉴定有利于优化馆藏、对重点地震科技档案的保管；并对提高档案工作服务水平和档案人员业务素质进行了探讨。     

Monumental space and the uncanny

This paper takes up the attempt to theorize the relation between the subjectivity of the political actor and the ideological aura of the monumental site. It does this with reference to the spatial history of Strijdom Square in Pretoria, South Africa, a cultural precinct and monumental space which was the site of a series of brutal racist killings committed by the Square’s unrelated namesake, militant right-winger Barend Strydom. This troubling intersection of subjectivity, space and ideology represents something of an explanatory limit for spatio-discursive approaches, certainly in as much as they are ill-equipped to conceptualize the powerfully affective, bodily and fantasmatic qualities of monumental spaces. In contrast to such approaches I offer a psychoanalytically informed account which grapples with the individualized and imaginative identities of space, with space as itself a form of subjectivity. I do this so as understand the ideological aura of monuments as importantly linked to the ‘intersubjectivity’ of subject and personified space. I then turn to Freud’s notion of the uncanny as a theory able to explain a series of disturbing affects of monuments, such as those of ‘embodied absence’ and ‘disembodied presence’. These and similar affects of ‘ontological dissonance’ (such as unexplained instances of doubling or repetition) may function in an ideological manner, both so as to impose a ‘supernaturalism of power’, and to effect an uncanny form of interpellation.     

北天山重点监视区地下流体临震前兆标志探讨

在“八五”短临预报和“九五”中短期（１年尺度）前兆研究的基础上,运用整点值、日测值、原始曲线法、一阶差分法和日工法,系统地分析了北天山１９８５年以来的地下流体前兆观测资料,研究了在此期间控制区范围内发生的７次Ｍs５.０级以上中强地震前临丑异常显示特征,探索了中强地震发生前地下流体临震前兆标志,表明只要正确地识别地震前兆的中长期向中短期、短期、临震前兆过渡的标志,并进行短临跟踪,是可以实现临震预报的。     

两株琼胶酶高产细菌的筛选和鉴定

从海洋环境中筛选得到两株琼胶酶的高产菌株，通过形态观察和生理生化反应，确定它们属于弧菌属，通过BIOLOG细菌鉴定系统鉴定，并同弧菌属标准菌株分析比较，确定上方宝剑两株菌都是塔式弧菌（Vibrio tubiashii)，这两株菌在碳源利用方面存在差别。     

气相色谱指纹法在海上油污染源鉴别中的应用

通过一个具体案例,探讨了气相色谱指纹法在海上油污染源鉴别中的应用。该鉴别方法基于样品的正构烷烃气相色谱指纹分析,选择既能表征油种固有特性,又受风化影响较小的正十七烷(n-C17)、正十八烷(n-C18)、姥鲛烷(phy)、植烷(phy)和正二十烷(n-C20)等特征烷烃作为判据,可信度大,而且整个操作流程短(一般不超过半天),较简便易行。     

产过氧化氢酶菌株CE-1 的筛选与鉴定

经过含H2O2的平板初筛和摇瓶发酵复筛,从保存的水样中筛选到一株过氧化氢酶高产菌株CE-1,其所产过氧化氢酶活性和比活分别为1 356.2 U/mL和3 401 U/mg。菌株CE-1为革兰氏阴性杆状细菌,根据其形态特征、16S rRNA基因序列系统进化树分析和生理生化特性,以及属内不同种间性状差异等因素的综合分析,将菌株CE-1鉴定为气单胞属(Aeromonas)细菌。     

Identifying geospatial services across heterogeneous taxonomies

Geospatial services with different functions are assembled together to solve complex problems. Different taxonomies are developed to categorize these services into classes. As differences in granularity and semantics exist among these taxonomies, the identification of services across different taxonomies has become a challenge. In this paper, an approach to identify geospatial services across heterogeneous taxonomies is proposed. Using formal concept analysis, existing heterogeneous taxonomies are decomposed into semantic factors and their various combinations. With these semantic factors, a super taxonomy is established to integrate the original heterogeneous taxonomies. Finally, with the super taxonomy as a cross-referencing system, geospatial services with classes in original taxonomies are identifiable across taxonomies. Experiments in service registries and a social media-based spatial-temporal analysis project are presented to illustrate the effectiveness of this approach.     

养殖黄颡鱼(Pelteobagrus fulvidraco) 鮰爱德华氏菌(Edwardsiella ictaluri)的分离鉴定与生物学特性研究

从四川眉山与新津两地患红头病的养殖黄颡鱼体内分离到2株优势菌(CHNYC001与CHNYC002),以腹腔注射与浸泡的方式进行人工感染试验,证实其为养殖黄颡鱼红头病的病原菌。根据分离菌株的形态、生理生化特性,结合16SrDNA序列测定(GenBank登录号分别为FJ766524、FJ766525)与系统发育分析,将其鉴定为鮰爱德华氏菌(Edwardsie lla ictaluri)。分离菌株最适生长温度为20—30℃,最适生长pH为7.0,在含盐量2%以上的培养基上不生长,对氟苯尼考、强力霉素、洛美沙星等敏感,对乙酰螺旋霉素、磺胺甲基异噁唑和麦迪霉素等不敏感。临床病理特征分析发现,养殖黄颡鱼感染爱德华氏菌临床上分为急性与慢性两种类型,急性型主要表现为败血症的病变特征,慢性型表现为头顶出血,发红与溃疡的病变特征。     

鄂尔多斯盆地陕北斜坡延长区块储层流体识别

延长油田区块位于鄂尔多斯盆地陕北斜坡东部延安单斜的中间部位,为研究天然气储层及储层中高含气分布区,2008年在延长油田区块内完成三维地震勘探344km2。本文对三维地震资料应用吸收系数、频谱分解、振幅衰减等地震属性进行流体识别试验。试验结果表明振幅衰减对含气层段异常响应相对敏感,吸收系数对高含气层段有一定反映。利用天然气储层各层段振幅衰减极大值,参考吸收系数剖面的高值层段,分析预测了三维区块含气概率高的平面分布区,2009年在预测的含气概率高分布区进行了探井验证,取得了比较理想的效果。
