郭家岭岩体矿物包裹体研究

通过对胶东金成矿区郭家岭岩体中熔融包裹体、含石盐子晶包裹体、ＣＯ２三相包裹体和Ｈ２Ｏ两相包裹体的显微测温,结果表明,该岩体在岩浆结晶晚期发生过高盐度流体与硅酸盐熔体的不混熔过程。根据熔融包裹体均一温度与均一过程的时间,利用相应公式,计算出郭家岭岩体包裹体熔体的粘度和含水量,认为该岩体是从一种高温高粘度的岩浆中结晶成岩的。

ER智能材料在结构振动控制中的应用

ＥＲ智能材料是一种可控流体,它能在电场的作用下可从牛顿流体变为剪切屈服应力较高的粘塑性体,且这种转变连续,可逆,迅速,因此,可用它来制作可调阻尼器,实现对工程结构风振和地震反应半主动控制,本文在简要地介绍了ＥＲ智能材料电流变效应的基本原理和影响因素之后,建立了适用于土木工程结构控制用的二种类型的ＥＲ可调阻尼器的工作原理和力学模型,并在介绍了ＥＲ可控阻尼器对工程结构风振和地震反应半主动控制的实施原则

Application of quantitative PCR method in detection of Lymphocystis disease virus China （LCDV-cn） in Japanese flounder （Paralichthys olivaceus）

Lymphocystis disease causes serious economic losses in the fish farming industry. The causative agent of the disease is Lymphocystis disease virus China (LCDV-cn), which has a wide range of hosts. Based on competitive quantitative PCR technology, we established a method to quantify the LCDV-cn in tissue. Results demonstrate that the average amount of LCDV-cn in the peripheral blood of infected flounder with evident tumors is about 106virions/ml while the average amount in those flounder with no evident tumor but cultured with the flounder with evident tumor is about 104virions/ml. No virus was found in the negative samples of flounder.

INTEGRAL/XMM views on the MeV source GRO J1411-64

The COMPTEL unidentified source GRO J 1411-64 was observed by INTEGRAL and XMM-Newton in 2005. The Circinus Galaxy is the only source detected within the 4σ location error of GRO J1411-64, but in here excluded as the possible counterpart. At soft X-rays, 22 reliable and statistically significant sources (likelihood >10) were extracted and analyzed from XMM-Newton data. Only one of these sources, XMMU J141255.6-635932, is spectrally compatible with GRO J1411-64 although the fact the soft X-ray observations do not cover the full extent of the COMPTEL source position uncertainty make an association hard to quantify and thus risky. At the best location of the source, detections at hard X-rays show only upper limits, which, together with MeV results obtained by COMPTEL suggest the existence of a peak in power output located somewhere between 300–700 keV for the so-called low state. Such a spectrum resembles those in blazars or microquasars, and might suggest at work by the models accordingly. However, an analysis using a microquasar model consisting on a magnetized conical jet filled with relativistic electrons, shows that it is hard to comply with all observational constrains. This fact and the non-detection at hard X-rays introduce an a-posteriori question mark upon the physical reality of this source, what is discussed here.     

吉尔吉斯斯坦布丘克造山型金矿床：来自流体包裹体、H- O- S同位素证据

吉尔吉斯斯坦北天山构造带的矿床学数据缺乏,制约了天山造山带境内外成矿对比。布丘克金矿床位于吉尔吉斯斯坦北天山构造带中部。金矿体为石英复脉,呈带状发育于NWW向韧性剪切带中。矿体倾向SSW,倾角60°～70°,赋矿围岩主要为侵入于早古生代变质碎屑杂岩中的正长斑岩。布丘克金矿床成矿期石英流体包裹体观察、石英H-O同位素、硫化物S同位素测试结果显示,布丘克金矿床石英脉中包裹体大小集中在2～10μm之间,类型以H₂O-CO₂型、富CO₂型、水溶液型包裹体为主,成分以富CO₂、含CH₄为特征。成矿流体具有中温(200～320℃)、低盐度(3%～7%NaCl_eqv)特征;石英δD_V-SMOW值介于-108.1‰～-90.2‰之间,δ¹⁸O_流体值介于4.86‰～9.26‰之间;黄铁矿δ³⁴S分布在0‰左右(-0.9‰～1.6‰)。综合本文数据、矿床地质特征、区域地质资料,本文认为布丘...
